GUELPH, ON – Putting a square peg in a round hole. That’s the challenge

window blind manufacturers face when it comes to covering an arched shape.

With mechanical engineering know-how and a number of prototypes

along the way, Macadam Blinds (www.macadamblinds.com) has unlocked

this challenge with its hardcover retractable Moon Shade Blind design. Units are available

in motorized- or cord-driven versions.

According to Macadam Blinds president Tom Lokody, the company had to address

several innovation obstacles – simultaneously – in order to be in a position to economically

produce the blinds for this classical window opening shape: “Our shade looks

simple, but there is so much behind it.”

What we can learn from

Japan’s industrial design

Studying another culture’s desires can shed light on your own

Geeky-Girly Innovation: A

Japanese Subculturalist’s

Guide to Technology and

Design might not be an enticing title

for everyone to pick up and read.

But as the father of two teenage

Canadian girls obsessed by

Japanese manga (comics) and

anime (cartoons), as well as the editor of two design

engineering magazines, this book by Morinosuke

Kawaguchi from Stone Bridge Press (www.stonebridge.

com) had my name on it.

The art and science of industrial design dictates that

the product developer must study the demographics of

the target market. Author Kawaguchi, principal associate

director for the consultancy Arthur D. Little Japan

and a lecturer at the Tokyo Institute of Technology, is

considered the inventor of a new concept in product engineering

and technology development that draws from

Japanese culture.

Analyzing everything from super-toilets to cute character

stationery goods, Kawaguchi argues here that the

Japanese have leveraged the childlike, feminine, cute aspects

of their otaku (geek) culture into top-tier products

for world markets.

When you see “Hello Kitty” pajamas, toothbrushes

and luggage from Japan here in the West – that is just the

tip of the iceberg, according to Kawaguchi. Wide-eyed,

cute characters in this vein have proliferated across the

daily lives of Japanese. Everything

from vending machines to highway

warning signs is replete with sweet

images drawn to inform and entice.

In Part 2 of the book, Ten Geeky-

Girly Rules of Japanese Products,

the author details Rule #1 – Make

the Object (Almost) Human: Anthropomorphism.

Japan’s polytheistic culture observes a

life force not just in living things but also inanimate objects.

Therefore, when something dies or breaks beyond

repair, it can be given funeral rites. Sewing needles, chickens

and germs are all recipients of this treatment in Japan.

This is where you find KFC honoring the dead that have

fed so many.

I was beginning to wonder if the country’s demographics

were just too foreign to consider transferring

its ideas to the rest of the world, but Kawaguchi demonstrates

how attractive Japan’s cultural influences can be

when he discusses robot and automotive design.

Cover Story FEATURE

Moon Shade solves multiple challenges

continued from Front Cover

Not only did the product have

to be defined for a market that is

accustomed to refined appearances

in its finishes, but so did the production

process, assembly machine

design and the materials used in the

blind blades. “We spent the better

part of 2009 working on these steps

– it has been the hardest design engineering

project I have faced in 10

years,” said Lokody. He added that

the design challenge was much more

demanding than a typical automotive

special purpose machine project

that his other company (EMD

Integration) gets involved in since

there were so many variables that

needed to be satisfied.

blade material thickness and height.

That way, we can tell if the blade

is too long and define the product

around standard window valences.”

The goal of Lokody is to grow

Macadam Blinds organically by

scaling up production. He noted

that since his production process

has been perfected, options for

adding more facilities is now a

possibility, as is the opportunity to

license the technology.

The archway opening is as old as

architecture, but to successfully cover

a window required the ingenuity and

engineering know-how of Macadam Blinds.

The expertise of Lokody has

been crucial to bringing the Moon

Shade closer to success after company

founder Mac Foy appeared

on season three of CBC television’s

Dragon’s Den in 2008 (http://ow.ly/

goez4) to demonstrate the product

and look for investors. Foy was

inspired to create the original blind

after waking up with sun streaming

through the top of an arch window

opening.

The Macadam production

assembly machine can customize the

size of the blinds in seconds due to

the machine’s simplicity, explained

Lokody. “We found a Canadian supplier

of blades that is already in the

window blind industry. The blades

also use the same sunlight-resistant

material found in matching horizontal

or vertical blind configurations.”

SolidWorks software has been

instrumental in bringing the original

Moon Shade concept forward.

“We wanted to reduce the number

of prototypes for the blade assemblies,”

said Lokody.

“Each customer provides dimensions

for a different opening, driving

the software to determine the proper

Sensors FEATURE

How to substantially reduce encoder cost

while gaining functionality

Multi-turn rotary position sensors employ a multi-layer scheme to accurately determine position

Many applications require

rotation counters that can

measure angles greater

than 360º. However, the low-cost

10-turn potentiometers most design

engineers are familiar with can’t

always meet user requirements for

resolution and reliability.

A better distribution

of the air is ensured in

the enclosure

As an alternative, optical absolute

encoders are too expensive for

many applications. These solutions

require a continuous power supply

or they will lose count when power

is restored. Also, geared technology/

rotation counters are subject to significant

wear.

Novotechnik RSM 2800 series

multi-turn rotary sensors address

this unfilled customer need. These

are the first rotation counters to be

based on Novotechnik’s patented

novoturn technology built on an

enhanced giant magnetic resistance

effect. They provide substantial

cost savings compared to optical

encoders, maintain reliability and

accuracy, plus they offer additional

useful features.

Magneto resistance is a phenomenon

in quantum mechanics that

occurs in thin film structures when

two ferromagnetic layers are separated

by a thin non-magnetic film.

It is a technology used in hard disk

drives. When the two magnetic layers

are parallel, resistance drops to a

minimal value. As the magnetic layers

are turned so they are no longer

in parallel alignment, electrical resistance

increases. This increase can be

By optimizing magneto resistive technology for encoder and positioning applications, Novotechnik has created a combined multi-turn

rotation counter and position sensor that senses without contact or power.

used to measure absolute position

values, e.g. full rotations.

Novotechnik has optimized this

patented technology for encoder and

positioning applications. The result

is a combined multi-turn rotation

counter and position sensor that

senses without contact or power. The

sensed count can be held without

power for years.

By measuring the resistance of

the structure, a custom integrated

circuit stores the changes of resistance

and applies a pre-determined

offset to count the number of turns.

The number of spiral tracks determines

the number of rotations that

can be detected.

A second 360° sensor is used

to determine the specific angle in a

single-turn range and combined with

the count sensor just described, this

technology can determine the angle

and number of turns- even tracking

when no power is present.

In the RSM 2800 series, two

multi-turn elements are offset by

90º in a diamond pattern. With this

structure, a clear rotation value can

be derived in any angular position

using a corresponding evaluation

algorithm.

The sensors are true “power on”

systems that provide these measured

values immediately following startup.

The technology eliminates the

need for the gears or the external

power supply required in conventional

rotation encoders. The result

is a series of very compact multiturn

sensors that can be easily integrated

into a wide variety of applications

to measure angles between

2 to 15 turns and supply absolute

position values over 360° without

mechanical gearing or a buffer.

And, since these are non-contacting

sensors, they provide long life and

can be easily integrated into a wide

variety of applications without the

need to create mechanical linkages.

The RSM 2800 is the first multiturn

rotation counter to be based on

novoturn technology. This sensor has

a 24 V power supply and 2 separate

0 to 10 V outputs (24 V supply) with

12-bit resolution. Units provide independent

linearity up to ±0.1% with

an electrical range up to 5400º. This

is a true power on sensor. The sensor

counts revolutions even with power

off, and no battery is required.

fulfill similar tasks but which are nevertheless

based on different protocols

continues to increase.

Turck has pursued a different

approach which provides a solution

for this challenge: The automation

specialist is launching the first multiprotocol

Ethernet gateways and

block I/O modules in the world that

can be operated with the Profinet,

Ethernet/IP or Modbus TCP Ethernet

protocols without any intervention

required by the user.

With its multiprotocol devices,

Turck is not only reducing the diversity

of proprietary device types, but

also the number of customers that

use different protocols in different

parts of their production or in different

country-specific versions of their

machines. In automotive production,

for example, it often occurs that body

construction and final assembly are

automated using different protocols.

In the future, all these users only

have to keep one gateway type in

stock, regardless of the Ethernet protocol

used. As purchasing and warehousing

are often centralized, this

will enable the costs and complexity

of inventory control to be effectively

reduced.

The multiprotocol devices make

it possible to implement machines

and plants that can be planned and

constructed identically. They can also

devices, Turck is offering

protocols.

be provided with different controllers

or masters to meet specific customer

specifications, enabling communication

in different protocols. Besides

the benefits with regard to spare parts

management and procurement, the

provision of multiprotocol devices

from other automation manufacturers

will make it possible to create

identical installation plans for electrical

designs which just have to be

duplicated.

Turck multiprotocol devices have

gateways that feature internal switches

which enable installation in line.

The Ethernet IP, Modbus TCP and

Profinet protocols are combined in a

single device firmware.

The multiprotocol functionality

is made possible by an intelligent

identification routine of the gateways.

During startup, they determine

which Ethernet protocol is running

on the cable by listening to the traffic

in the so-called snooping phase. The

devices then automatically switch to

the detected protocol and ignore the

telegrams of the other two.

The implementation of the protocols

is in no way inferior to that

of the single protocol devices. In

Profinet mode, topology detection

and address allocation are supported

with LLDP, and Ethernet/IP with

QuickConnect and Device Level

Ring (DLR media redundancy).

However, the multiprotocol talent

is not the only source of innovation

on the new Turck gateways. The

multiprotocol devices also have a

turbo on board that enables a highspeed

startup. They support Fast

Startup in Profibus mode and feature

QuickConnect in Ethernet/IP mode.

Due to the extremely slim architecture

of the microprocessor and the

operating system, they can achieve

startup times that were previously

impossible.

The automotive industry in particular

required short startup times

in order, for example, to increase the

cycle rate for a tool change on robots

in body shell construction. The faster

the I/O module on the tool changer

returns to operational readiness, the

faster the cycle time for an operation.

For the automotive manufacturer, a

shorter cycle time means either more

output per unit of time or fewer

robots for a particular operation –

both significant alternatives from an

economic standpoint.

Turck developed an optimized

electronic architecture for its

Ethernet I/O modules that ensures

that processors are operational considerably

faster – largely regardless

of any protocol modifications – and

speeds up the startup times. The

Turck block type fast startup modules

now achieve startup times of

Improving safety in LNG applications

Automation control systems meet hazardous environment compliance

The chemical make-up of natural

gas induces complex contaminates

such as CO, H 2

S,

CO 2

and other acidic gases which

can hinder the liquefaction process.

Several operations are needed not

only to overcome the process bottlenecks,

but also to meet liquid natural

gas product specifications, and to

prevent corrosion of process equipment

and the plant environment.

This environment is known as

a Class 1, Div 2 hazardous location.

Several options are available to

deploy an automation control system

in a hazardous environment. In

the past, NEMA 7 Explosion Proof

Enclosures were predominately used

to prevent an arcing or flame from

a component failure inside to the

outside volatile process area. Today,

a NEMA 4/4X industrial enclosure

is commonly employed with an air

purge system.

As a replacement to both of

these options, E-T-A offers a line of

solid state electronic circuit breakers

for Class 1, Div 2 hazardous

location applications. This new

solid state technology is an alternative

to 24 Vdc field devices in a

hazardous location because as long

as all the components in an electrical

control enclosure have a Class

1, Div 2 approval, the NEMA 7

enclosure and/or purge system are

no longer needed to meet most

application specifications.

Integrating E-T-A’s solid-state

devices, a leading North American

liquid CO 2

and liquid natural gas

(LNG) system supplier has successfully

implemented the products on a

LNG pre-treatment application.

The company benefited from better

protection for field devices than

any other technology available for

24 Vdc switch mode power supplies.

The E-T-A product is designed

to detect both overload and shortcircuit

conditions within 200 ms of

the overcurrent event. Because this

component has a current-limit function,

it will supply no more than 1.3x

rated current of the circuit breaker at

any time during the fault condition,

then after 3 s it completely disconnects

the current from the switch

mode power supply to the load.

In the event of an overload or

short circuit, the device allows for

individual disconnection between

the power source and the load

via a power switch on the face of

the product. Other models have a

Remote Reset option allowing a

PLC/DCS control output to disable

or disconnect the current flow to

the field load preventing the power

supply from being compromised by

a single point of failure.

This product carries a UL 1604,

Class 1, Div 2 (CIDC) approval,

which allows it to be used in this

application with a CID2 switch mode

power supply, I/O modules, terminal

blocks, and industrial switches.

Motion Control FEATURE

Slide bush components inspire designs

Printer assembly and linear digital measuring device applications benefit

By Larry Hansen

Specialty Motions, Inc. (SMI), a

linear motion components distributorship

in California, was

inspired by simplicity – the simplicity

of creating assemblies that solved

motion control problems.

Specialty Motions

is now both a

distributor and a

manufacturer

For example, a client’s need for

an inexpensive, easy to maintain

way to load material into a printing

system led SMI (www.smi4motion.com)

to create a simple, reliable

X/Y assembly.

SMI attached aluminum pillow

block slide bush components to a

custom machined metal plate. SMI

founder Tom Corey explains the

choice: “If something were to happen

– say it (a bearing) wears out

over time – and everything wears

out – it is so easy to replace the bearings

inside an NB Corp. of America

(one of the manufacturers that SMI

carries) pillow block as opposed to

the competition.

“With (product from) NB, all

you do is take four fasteners off the

bottom, remove a skip plate and

the old bearing slides out. You put

the new bearing in place, put four

fasteners back in and you’re off and

running again. With the competition

on the other hand, they’re pinned in

place by a roll pin. You have to either

destroy the pillow block or the roll

pin to get this thing apart and typically

you can’t get the new one back

in using the same hole.

‘With the NB product you

can replace the bearings internally

without destroying the block.

With the competition you have to

replace the whole block and it is

twice as expensive.”

In the case of another SMI customer

application, SMI needed to

measure long flat, square or round

materials, such as shafts, right at

the shop floor – beyond what the

typical vernier caliper could measure.

To construct the measuring

device, they used the open pillow

block slide bush type TW8UU from

NB’s TOPBALL self-aligning slide

bush line.

SMI combined a half-inch slide

bush with a shaft and incorporated

a 120 in. linear scale with a Digital

Read Out. The DRO consistently

reads where the carriage is relative

to the end plate. The linear digital

measuring device (LDMD) can be

fixed or mobile. A “VEE” groove

allows the material to accurately

nest for measurement. The LDMD

is capable of accuracies up to ±.001

in. and any length up to 120 in.

The unique characteristics of a

tremendous variety of reliable and

easy to maintain slide bush components

made all of these assemblies

cost effective. Now SMI is both a distributor

and a manufacturer.

CAD Industry Watch

By Bill Fane

Prepare to set your sights on DraftSight

Is “free” really an actual price

ASolidWorks have been a

prime mover in the MCAD

market ever since they were

the first to release a parametric 3D

MCAD modeller written specifically

for Windows 95.

Dassault Systèmes

probably hopes to

make up sales by

attracting users to its

3D products

Before long, however, it realized

that not all MCAD design work should

or could be done in 3D and that

AutoCAD’s .DWG file format was

the de facto industry standard for 2D.

Accordingly, it soon began including

DWGeditor in its SolidWorks package.

A couple of years ago Dassault

Systèmes SolidWorks (www.solidworks.com)

announced it was discontinuing

DWGeditor and replacing it

with a new product called DraftSight.

Dassault Systèmes did more than

“replace,” however. DraftSight is available

as a free download for anyone

from www.draftsight.com, and is not

limited to being bundled with any

other CAD product. It’s available for

Windows 32-bit and 64-bit, Mac

OS-X, and in several Linux flavours. A

significant point here is that it is being

branded as a Dassault Systèmes product

rather than specifically SolidWorks.

So how do you make any money

from a free program An MBA would

reply, “They’ll make it up in volume.”

Dassault Systèmes, on the other hand,

probably hope to make it up by attracting

users to their 3D products.

Basic DraftSight is free, but it needs

registration (an e-mail address) and

activation to run. You can also pay

for the Premium version to get additional

features such as tech support

other than a discussion group, network

licensing, and support for Lisp programming.

Three factors to be considered

when discussing “compatibility” are

the user interface, commands and

options, and file format.

DraftSight V1R3, the latest version,

is much closer to being AutoCAD

LT than it is to full AutoCAD. Even

then, the user interface is an interesting

point. It is either very close to matching

AutoCAD or it’s completely different

in that it retains the “traditional”

interface of a menu and toolbars of

AutoCAD 2009 and earlier rather than

adopting the later Ribbon interface. I

leave it up to you to decide if this is the

good news or the bad news.

DraftSight nominally supports the

AutoCAD 2013 file format. AutoCAD

normally only changes format every

third release, so it will be interesting to

see how DraftSight handles AutoCAD

2014 and 2015 files. Even so, this still

puts it ahead of many of the clones and

compatibles that often lag behind by

one full file format.

DraftSight V1R3 significantly

improves file compatibility compared

to earlier releases. For example, selfscaling

annotative objects such as text,

dimensions, and hatching now survive

a round trip from AutoCAD out to

DraftSight and back again, but while

in DraftSight you can only see the scale

configuration that was current when

the drawing was saved in AutoCAD.

The parametric functionality from

AutoCAD 2010 and later now seems

to survive a round trip with a couple

of interesting quirks.

First, if you edit the specific dimension

text or if you edit objects directly

using grip editing in DraftSight, then

everything updates back in AutoCAD –

sort of. Nothing happens in AutoCAD

until you click on an object that has

parametrics attached, and then everything

updates – sort of. If you changed

the parametric text in DraftSight then

the objects update, but if you edited

objects directly using grips then the

AutoCAD parametric values rule and

you lose the grip edits you did.

The other interesting quirk is that

somewhere during the round trip it

looks like all your dimensional constraints

have vanished, but all that

really happens is that the AutoCAD

system variable AnnoAllVisible gets

turned off.

But Wait! There’s more!

DraftSight V1R3 also introduces

several other new features. First, the

preferred way of working these days

is to create ortho views in model space

and then create paper space viewports

to arrange them to suit the sheet layout.

The problem has been that it wasn’t

easy to get the model views to align

correctly, but V1R3 adds new functionality

that greatly simplifies the process.

To further enhance this

DraftSight is available as a free download for anyone from www.draftsight.com, and is not

limited to being bundled with any other CAD product. It’s available for Windows 32-bit and

64-bit, Mac OS-X (shown), and in several Linux flavors.

The default screen for DraftSight V1R3 to start or modify a DWG-compatible 2D drawing.

drawing technique, V1R3 adds

“SmartDimensions.” They include the

ability to reach in through a sheet

viewport and snap onto model entities,

but better than that they are smart

enough to recognize the entity type.

Thus, a single run of a single command

can apply mixed combinations of horizontal,

vertical, or aligned dimensions

to lines, or between two points such

as the end of a line and the centre of a

circle, or the angle between two lines,

or the radius or diameter of an arc or

circle. That’s right; all from a single run

of one command!

Additional capabilities in

DraftSight V1R3 include revision

clouds, an in-place text editor, and

the ability to explode text plus several

more new or improved features.

Finally, it now offers 3D mouse

support. This may seem a little silly

for a 2D CAD program with limited

3D support, but it does make sense if

you’re running a 3D modelling program

on the same computer and are

using a 3D mouse for it. Now the same

mouse can serve both programs.

Is it still plagiarism if I copy from

myself The following summary is lifted

almost straight from my previous

review two years ago, but it still very

much holds true.

I would describe DraftSight as

“works very similar to” AutoCAD

2009 LT and is “mostly file compatible

with” AutoCAD 2013. In fact, it

is probably the most compatible of the

various “clones” that I have seen. It is

a competent, viable 2D product in its

own right, especially considering the

price.

Automotive Scene

By Bill Vance

Nissan makes steer-by-wire leap-of-faith

Solid mechanical link to wheels set to disappear

Since the dawn of the automobile

cars have been guided by a driver

turning a steering wheel, or

moving a tiller in some very early cars.

One characteristic of the system

was that there was always a solid

mechanical link, whether by gears,

shafts or rods, between the driver’s

hands and the vehicle’s tires. But the

method that has survived to this day

is about to be challenged.

Perhaps it is not surprising in an

era of electronically actuated throttles,

called drive-by-wire, which are now

almost universal in new cars, or even

the brake-by-wire that is starting to

creep in, that steer-by-wire is coming

on the scene. Nissan announced

in October 2012 that it will pioneer

automobile steer-by-wire in which

the traditional mechanical connection

between steering wheel and tires is

replaced by electronic signals. It plans

to introduce steer-by-wire on some

Infiniti G-series models within a year.

Steer-by-wire should not be

confused with increasingly popular

electrically assisted power steering

in which the traditional belt-driven

hydraulic pump is replaced by an electric

motor. Steer-by-wire is a different

concept, although it is not new, having

been used to regulate the movement

of control surfaces on airplanes for

several decades where absolute reliability

is critical. It is also found in

more mundane applications like tractors

and forklift trucks.

While Nissan’s will be the first

automobile production version of

steer-by-wire, it will not be the first

demonstration of the technology.

About a decade ago General Motors

showed its futuristic Autonomy concept

car powered by a fuel cell, and

with full by-wire capability, including

steer-by-wire. GM built several prototypes

but so far there appear to be no

firm production plans.

Nissan calls its steer-by-wire system

Independent Control Steering

Technology because it “allows independent

control of a vehicle’s tire angle

and steering inputs.” When the driver

turns the steering wheel it sends a

message to the electronic control unit

(ECU) that processes the signal and

forwards the appropriate signal to two

electric motors, one for each wheel.

The motors instruct the steering

angle actuator (a rack-and-pinion

system) to direct the wheels. Nissan

says it eliminates the fatigue-inducing

need to grip the steering wheel

tightly to counteract the vibrations

and disturbances caused by things

like road irregularities, ruts, ridges

and potholes.

Steer-by-wire also compensates

for road camber changes, curves and

cross winds, and is said to operate

faster than a mechanical connection.

And lest driving enthusiasts despair,

“road feel” can be engineered into the

system, implemented by an electric

motor near the steering wheel.

The scheme uses Nissan’s

“straight-line stability system” in

which a camera mounted above the

rear-view mirror “reads” road markings

to provide lane control and monitor

road curves and vehicle direction

changes. If deviations are detected, it

signals the ECU (electronic control

unit) that makes slight steering angle

adjustments as required.

The system can also be engineered

to automatically steer the car

around obstacles such as pedestrians,

a feature that could make it a building

block for the totally autonomous

vehicle in the future.

Nissan claims several advantages

for steer-by-wire. Because there is no

mechanical connection between tires

and steering wheel, the system isolates

the driver’s hands from the road.

Another advantage is that the

steering ratio can be adjusted for

changing conditions such as high

speed cruising, slippery road surfaces

or even parking manoeuvres where

different rates of tire response to

steering wheel movement would be

advantageous.

The big concern of motorists, of

course – and a possible psychological

barrier – will be the fear losing control

of the vehicle in the event of a system

failure. Nissan recognizes this and their

engineers have built several steps of

redundancy into the electronic system.

In addition, they had provided the ultimate

failure insurance by retaining the

conventional steering column.

In the unlikely event of a power

failure a clutch automatically makes

a mechanical connection between the

steering wheel and the road wheels.

While it will seldom be required, it

will ease the mental barrier of transitioning

away from that age-old and

reliable mechanical link.

Steer-by-wire definitely appears

to in our future, but unlike throttle-by-wire

and even brake-by-wire,

electronic steering control will be a

larger, but likely not insurmountable,

mental hurdle for drivers.

Intelligent eyewear recovers usable vision

Sight, sound, taste and touch are the senses

that engage us with the physical world and

the loss of any one of them can seriously

compromise our work, our pleasures, our safety,

our security and our connectedness with others.

In 2006, Conrad Lewis, a well-known Ottawa

technology veteran founded the intelligent eyewear

company eSight Corp. (www.esighteyewear.

com). The eSight technology is an amalgam of

those that Lewis acquired from his Mitel and

Newbridge experiences and applied now in a

manner that can benefit people with impaired

vision.

Lewis is personally acquainted with vision

problems – although certainly not in the business

sense. His wife is severely nearsighted and he has

two sisters who have Stargardt’s disease, a disease

that causes people to be especially sensitive to

glare and the disease for which eSight developed

No other electronic low vision aid is mobile,

hands free, and suitable for near, far, and mid-range tasks.

its original prototype.

The eSight device consists of a headset, a

frame that includes personalized prescription

lenses, and a controller that holds a 4-hour battery.

Each unit can be calibrated to suit its user’s

medical condition and the lenses can zoom to

text and allow a book to be read at a normal

distance rather than holding it against the face.

The eyewear incorporates a high-resolution

video camera and a bright, high–contrast, “virtual”

display for each eye. The eyewear is

personalized and algorithms are programmed

according to the user’s eye condition and preferred

activities and, in addition, prescription

lenses can be built directly into the eyewear.

eSight is most suited to people with visual

acuity between 20:60 and 20:400, and for

people under 75 years old. It is not suitable for

those with severe tunnel vision.

Linear drive with adjustable pitch enables variable speed

without changing drive motor speed

All Uhing Model RG linear drives from Amacoil now feature a manual pitch control which permits a 10:1 adjust-

ment of the linear pitch of the drive unit. Each of seventeen Model RG drive units has a specific

maximum linear pitch. This is the linear distance the drive will move on the shaft per one

revolution of the shaft. The pitch control lets users turn the pitch down in 0.01 increments

across one hundred discrete settings. For example the model RG30 drive has a maximum

pitch of 26.0 mm and may be turned down to 2.6 mm.
