I have to say our office has a ghost and her name is Cini, last week we
came in and papers on desks were scattered everywhere and to boot the art
work had her face on it. So, in her memory we did not change anything
and ran with it, so this Cini edition we dedicate to all of you in reader’s
land who have lost your best pal! Oh, don’t mind her foot prints at the
bottom of the pages.
In this March issue we cover the exploration of hack not to hacking and a
chock full technology for our dogs and may I say I was totally awed by the
technology that is coming out for our loyal canine.

To Hack or not to Hack
Your cell phone
That is the question!
If I, Shakespeare, were alive today I would be having a field day with your
21 st century technology. So, you found, given, passed down to you, however
“legally” you got it, the fist thought is;
1: young, teenager range “let’s hack it”
2: mid 30’s to 40’s “I know a cell shop, money no problem”
3: 50’s + “Hey, I’ll just clean the data junk and apps I don’t want and
Set it up as a PDA!”
What is a PDA? I shall tell you, “A personal digital assistant (PDA), also
known as a handheld PC,[is a variety mobile device which functions as a
personal information manager. PDAs were largely discontinued in the early
2010 after the widespread adoption of highly capable Smartphone’s, in
particular those based on iOS and Android.”
So, aaaaaaaa love ya Billy, my turn!!!!!
I spent 4 days on research on how to hack a Samsung Galaxy J3
(pict 1) and bypass Google block, I can tell you that everyone in
cyber land has ―THE FIX‖ and I tried the top 30 and they are all
duds and the reason is you don’t know if or any updates were ever
done to the operating system which would have plug those holes.
Pict 1.. Samsung Galaxy J3
If you are asking why we reset the phone to factory, well, two
phones that came in to our possession the J3 on the left and the
one below Galaxy S6 – G920A. We kept the S6 for its memory,
speed and updates, so, the S6 was the 1 st to go on the bench and
we meticulously went through it , deleted all data and apps we did
not want then put in our own contacts and apps, now we have a
modern PDA, here is some the apps we installed from Google
1: Snap Biz Card
2: QR Code Reader
3: ES File Explore
4: File Manager +
6: Messenger... You can make private calls via internet
7: Dropbox & 4Shared
8: Textfree ... This app I have used over yrs, you get a phone
number you can use...Look into it
This is some of the business apps we use a lot, number 7 is
great, take pictures on the fly then up load then, call the
office and they have it of if they are out they can see it on

How These 5 Advances in Dog Tech Could Change
SXSW (South by Southwest) is happening right now, and in addition to new musical acts, it
increasingly highlights exciting developments in the tech world. And that includes the dog tech
According to the American Pet Products Association, Americans spent over 60 billion dollars
on their pets last year, and the tech world is cashing in with innovative, practical, and downright
silly stuff to make life with your dog more advanced. From pet wearable’s to doggy spy cams to
novelty tech that’s more fun than functional, these are the craziest tech advances for dogs.
One of the earliest and still-hottest tech trends for dogs is wearables that track their activity.
Dog fitness trackers are great if you’re trying to help your dog lose weight, or just want to
generate some cool charts and graphs based on their daily activity.
FitBark was one of the first pet activity trackers on the market, and may be the most popular.
It’s a colorful, bone-shaped device that attaches to your dog’s collar, monitors her activity
throughout the day, and syncs to your smartphone or computer via bluetooth. PC Magazine
praises FitBark’s app and build-in social network, which lets you set a ―BarkPoints‖ activity
goal, compare your dog’s stats to others, and track her progress over time.
Newer pet trackers emphasize safety over fitness, using built-in GPS to track your dog’s
whereabouts, which can provide life-saving location services if she gets lost. Devices like
Whistle let you set up ―virtual fences‖ by designating specific coordinates as your dog’s
home/safety zones. If your dog strays beyond the boundaries, the device will send an alert to
Surveillance Tech Toys

Do you come home from work to mysteriously chewed-up couch cushions? Wondering what
else your dog is up to while you’re out of the house? The latest tech for dogs combines good
old-fashioned surveillance with interactive features to remind your dog that you’re with them,
even when you’re not.
Sure, you could just set up a simple webcam to keep an eye on your dog during the day. But
why stop there? The PetCube camera syncs to your smartphone and lets you watch, talk to,
and even play with your dog from afar (though the built-in laser dot ―toy‖ may be more
appealing to cats than dogs). The PawsCam is a motion-activated camera that affixes to your
dog’s collar and points the lens outwards, so you can watch recorded video from your dog’s
point of view (I have a feeling I’d get an inside view of the cat’s litter box, my dog’s favorite
place to visit when I leave).
Then there are gadgets that combine monitoring with food motivation. For instance, the Petzi
Treatcam streams a basic video feed to an app on your phone, which you can use to monitor
your pup, connect with other pet people, and ―treat‖ your dog remotely. Very cool!
Looking for a fun, interactive puzzle toy to keep your
dog busy while you’re at work? There’s an app (and
gadget) for that!
Puzzle toys like the PupPod combine surveillance tech
(a camera that streams video) with training incentives (a
challenging game resulting in tasty treats), and it’s all
controllable remotely, so you can join in the fun from
Video games for dogs may sound like a joke, but guess
what: they’re already here! The CleverPet ―game
console‖ doesn’t have a camera or controller, but it’s a
treat-dispensing puzzle toy that challenges your dog
with light-based puzzles, and streams data to an app you
can follow from work.
Via NPR.org/Georgia Tech
Safety features are a major draw in dog tech, but some companies are taking it one step further
with products designed for dog and human safety alike.
The FIDO vest is wearable technology designed with service dogs in mind, meant to not only
supervise your dog, but provide extra safety to humans. FIDO stands for ―Facilitating
Interactions for Dogs with Occupations‖ and according to the creators, this vest was designed to
expand what service dogs can do (source). For instance, if a physically impaired person is in
danger, their service dog can use a tug or bite sensor on the vest to call 911. Now that’s lifesaving
If you’re looking for truly innovative, wearable, does-it-all pet safety tech, the Kyon Pet
Tracker may be your best bet. This sleek collar isn’t even available commercially yet, making it
all the more elite. In addition to activity tracking and a built-in GPS, the Kyon has a heat sensor
that sends an alert if the external temperature is dangerously high, and a water sensor for dogs
that aren’t strong swimmers. It even claims to sense your dog’s mood: if the Kyon notices your
dog’s activity level is especially low, it sends an alert to your phone reading, ―I’m not feeling
well!‖ With a starting price of $249, plus a $4.99/month fee to cover the cellular tracking
network, the Kyon collar isn’t cheap, but it’s hard to put a price on being the coolest canine tech
on the bloc.
Just for Fun
What’s the point of all this crazy new technology if we can’t have a little fun? There are plenty
of just-for-fun apps and devices available to make life with your dog more tech-savvy
If you’re looking for a fun diversion, check out Fetch!, the app that identifies breeds based on a
picture, but is most fun for categorizing humans as dogs. Fetch! had a little trouble identifying
my pit bull mix, but it correctly identified me as a pug at heart.
Then there’s tech-infused fashion for dogs, from a “smart harness” with a camera mount
to the DiscoDog LED vest, which lets you customize light shows and text messages to turn
your dog into a light-up billboard.
Finally, the craziest tech advance for dogs just might be the tech advance that is a dog: Boston
Dynamics’ robot dog, Spot. Though based on the video recently released by the design team,
Spot isn’t about to replace real dogs. Technology is cool, but nothing beats the good oldfashioned,
analog companionship of a warm-blooded dog.

Dogs, technology and the future of disaster response
May 6, 2014, North Carolina State University

Imagine a team of humans, dogs, robots and drones swooping onto the scene in the
aftermath of a disaster and working together to find and rescue anyone trapped in
collapsed buildings. That's the goal of a team of researchers from around the United
States working on what they call the Smart Emergency Response System (SERS).
The team is part of the Smart America Challenge, which kicked off in late 2013 to
highlight state-of-the-art, practical innovations stemming from U.S. research. The
SERS team is one of more than 20 research groups presenting projects as part of the
The SERS project's goal is to use cyber-physical systems to share information and
coordinate emergency and disaster response and recovery. These systems are
designed to work in real-time via a variety of wireless network technologies. In
addition to NC State, the SERS team includes researchers from MathWorks, the
University of Washington, MIT, BluHaptics, National Instruments, the University
of North Texas, Boeing and Worcester Polytechnic Institute.
The NC State researchers, Alper Bozkurt and David Roberts, are focused on a very
specific aspect of the SERS equation: dogs.
Roberts and Bozkurt have developed a high-tech harness equipped with sensors and
other devices that will both make the dogs more effective at collecting information
and incorporate the dogs into the larger network of a coordinated disaster response.
"We're using a range of technologies to modify off-the-shelf harnesses," Bozkurt
says. "And of course, all of the tech is supplemented by training for the dogs and
Credit: Alper Bozkurt "We're not trying to replace dog handlers – we're trying to open the door
to new possibilities," says Roberts, who is also an experienced amateur dog trainer.
The SERS dog harnesses include three kinds of technologies: environmental
monitoring, dog monitoring and active communication.
The dogs will be equipped with passive environmental monitoring devices – such as
microphones, cameras and gas sensors – that allow the dogs to retrieve and transmit
data from the field in real time.
"We're developing a platform for sensors that is designed to be plug-and-play,
allowing emergency responders to further customize the harness," Bozkurt says.
"For example, if there's the possibility of a natural gas leak, you could attach a
natural gas sensor. Or if there's the possibility of radiation, you could attach a
Geiger counter." Using wireless communications, the sensors can be monitored
remotely at a command center or by dog handlers on a handheld device nearby.
The harness also includes new sensors developed by Bozkurt and Roberts that
monitor a dog's behavior and physiology, such as heart rate. These sensors will
allow both dog handlers and the emergency response command center to remotely
track a dog's well-being and to determine if the animal has picked up a scent or
found a specific object or area of interest.
The active communication technologies on the harness will allow handlers to relay
commands to a dog remotely. Bozkurt and Roberts have incorporated audio
communication, via speakers, into the vest. However, they think the more reliable
remote communication will come via "tactile inputs" – they're training dogs to
respond to gentle "nudges" that come from within the electronic harness itself.
"I want to be clear that these are not aversive punishments, but slight, tactile nudges
from motors in the vest – like a vibrating cell phone. We're using exclusively
reward-based training techniques," Roberts says.
Bozkurt, Roberts and the rest of the SERS team will be participating in the Smart
America Challenge event in Washington, D.C., this summer.
"After that, we plan to continue to engage emergency response personnel to identify
and overcome any obstacles to putting these smart-recovery techniques to work in
the field," Roberts says.

New Technology to Help Search and Rescue Dogs
March 4, 2016
Rescue dogs may soon be equipped with new technology to help improve their
Japanese researcher Kazunori Ohno is in the midst of developing a technology pack
that includes a tiny camera and a GPS device to be strapped to a search dog. This
equipment will record exactly what the dog sees and transmit the live video and a
map to a handler’s tablet. This will help overcome a huge problem handler’s face
when dealing with rescue dogs: not knowing what happened to the pup once he
entered a damaged structure or a hard-to-access location.
―A handler can check a video to see where a dog is searching, how it looks inside a
building and where survivors are located,‖ Ohno told AFP News.
The hope is that this will help expedite rescue efforts, as searchers can more easily
find survivors. And with Japan being a hotspot for earthquakes and tsunamis, this
advancement could have major implications.
This sort of technology — cameras and GPS — have been used by other agencies,
including U.S. military units, but Ohno says his device is much more lightweight,
allowing smaller, more nimble dogs to use it. Also, his innovation allows the live
video to stream to various tablets, rather than just one.
While the researcher has also been devoting his time to developing rescue robots,
which allows agencies to work longer hours and enter more dangerous locations,
Ohno says these machines don’t match the canine’s ability to find survivors quickly
over a wide area.
―I’ve learnt what robots can and cannot do… So I thought I could develop a new
technology that can unite dogs and robots,‖ he told the outlet.
He is currently working with Japan Rescue Dog Association to refine the
technology and hopes to soon begin renting the packs out to search-and-rescue

TOP 5 TECH DEVICES FOR DOGS
November 14, 2014
by Alicia Rius
As humans, there are very few of us who aren’t constantly attached to our favorite
piece of technology. Our iPhones, our iPods, our FitBits and BlueTooth devices are
constantly in use. Technology though, isn’t just for humans any more. There is tons
of wearable technology out there for our pets. Yes, you read that right, our pets.
This is a far-from-comprehensive list of some of the top tech tools out there for
Whistle is one of my favorite doggie tech products out there. It functions a lot like
the FitBit does for a human by tracking your dog’s activity 24/7. It allows you to
download your dog’s activity information and compare it to other dogs and breed
norms in certain areas.
I like that it is tiny and clips to your dog’s collar, it’s waterproof, and she’ll barely
even notice it’s there. It provides tons of cool and useful information.
Whistle retails for around $129 and you can purchase it here.
2. Fit Bark
Fit bark is a mobile wearable activity monitor for your dog. It clips on your dog’s
collar and you can monitor her activity via smartphone app.
I like it because it helps you take better care of your dog in getting them the
exercise they need.
You can learn more and pre-order FitBark here.
3. Pet ReMote
The Pet ReMote is a wearable mobile training device that allows you to train your
pet from your smartphone. A small device attaches to your dog’s collar and you are
able to control the device from a smartphone app using BlueTooth. The device uses
acoustic or vibration to correct behavior, never shock.
I like it because it simplifies training and doesn’t add any additional gadgets for me,
the human, since I already use my smartphone all the time.
You can purchase it here for about $30.
This is a hybrid GPS/pet-tracker. It not only tracks your pets whereabouts, but also
logs activity data for your pal. This awesome little gadget that clips on to your
dog’s collar will send text messages to your phone if your dog ends up outside of
the pre-set zone you set up so you can always be one step ahead of your dog.
I like this device because it lets you know when the battery is low by also sending
you a text message. This way, you can rest assured knowing the batteries are good
to go incase your dog decides he’s good to go!
Purchase Tagg here for $99.95.
PetHub is a dog ID that has gotten a dose of smart. There is a QR code on the back
of the tag that when scanned reveals all pertinent owner information so your pet can
be returned safe and sound. PetHub also sends you a notification when the QR
code is scanned so you will know right away if your dog has been found.
My favorite thing about PetHub is that is also lets you embed any necessary
medical information into the QR code as well. If you have a diabetic dog or a dog
with severe allergies and you can’t be reached right away, this allows your dog to
receive the care it needs in the interim.
PetHub tags start at just $9.95 and can be purchased here.

Armor to guard $50,000 dogs
K9 Storm's canine armor and communication systems help keep working dogs
safe on the front lines of wars and police actions.
By Jonathan Blum
Last Updated: November 30, 2009: 1:53 PM ET
(Fortune Small Business) -- It's a tough world for man's best friend. Patrol dogs dodge
bullets every day at home and risk their lives sniffing out trouble in Iraq and
As a result, K9 Storm in Winnipeg, Canada,
makes $5 million a year selling custom armor
for dogs in the U.S. Army, Navy, Marines and
Special Forces; police departments in 13
countries; and security firms worldwide.
Next up, the 12-employee firm is offering a new
way to communicate with canines. In 2010 it
launches the K9 Storm Intruder, a bulletproof
dog vest with a wireless camera, speakers and a
microphone built in. The handler can see what
the dog sees and issue commands through the
"This will change the way dogs are managed in
emergencies," says Glori Slater, 47, vice
president and co-founder of K9 Storm. "It will
extend the range of the handler to 300 yards."
Slater's husband, Jim, is a former dog handler
for the Winnipeg police department. For two
terrifying days in 1996, he and his German
K9 Storm makes custom vests,
like the harness worn by this
Special Forces dog.
shepherd Olaf helped subdue a prison riot in which the inmates were armed with
makeshift weapons. Slater worried more for Olaf than for himself.
"He was out working ahead of our lines," he says. "I realized it would be a bad way
for him to go down, stabbed with a screwdriver."
After the riot, Slater retrofitted a human flak jacket for his canine partner. That
prompted orders from fellow canine officers, and soon K9 Storm was in business.
The Slaters spent 11 years perfecting the vest. Quality control was crucial, given
that a poorly sewn seam can inflict crippling lesions on a dog that's on its paws for
12 hours a day. The Intruder is their lightest camera and audio system, weighing
less than seven ounces.
The vest is not cheap. The Intruder system starts at $20,000. But the Slaters say
they have dozens of preorders. Military working dogs are major investments,
costing up to $50,000 each to purchase and train.
There also are plenty of donors stepping up to help cash-strapped municipalities
buy the vests. Ben Roethlisberger, the quarterback for the Pittsburgh Steelers, gave
$250,000 to the Pittsburgh police and fire departments for canine armor.
The Massachusetts Society for the Prevention of Cruelty to Animals, which treats
50,000 animals a year, has received a $5,000 grant for dogs at Boston's police
department from Roethlisberger.
"Suspects pursued by police will stab, shoot and kick working dogs," says Brian
Adams, spokesman for the MSPCA-Angell veterinary hospital in Boston. "They are
like any officer of the law. We want to protect them."

Something to enlighten you up
Could the ancient Romans have built a digital computer?
The Romans were undoubtedly master engineers. They were experts at civil
engineering, building roads, improving sanitation, inventing Roman concrete, and
constructing aqueducts that adhere to tolerances impressive even by today’s
standards. Perhaps the best evidence of their aptitude is the fact that many of
those structures still stand today, almost 2000 years later. They even began
dabbling in technology vastly ahead of their time. Hero of Alexandria drew up
plans for a rudimentary steam engine in his Spiritalia seu Pneumatica. He called it
It didn’t work very well. However, by the late 3rd century AD, all essential parts for
constructing a steam engine were known to Roman engineers: Hero’s steam power,
the crank and connecting rod mechanism (in the Hierapolis sawmill), the cylinder
and piston (in metal force pumps), non-return valves (in water pumps) and gearing
(in water mills). That got me thinking: Could the Romans have built a digital
computer using only the technology and manufacturing processes available to
Maybe the first thing you would think of is a mechanical computer, like the
Babbage Difference Engine:
While it’s a beautiful piece of engineering, it’s actually not a computer. It’s a
calculator. Charles Babbage did design a mechanical computer, called the analytical
engine. It’s never been built, because it would take up an entire room and be
extremely expensive. I don’t think the Romans could have built the analytical
engine or other purely mechanical computer because of the tolerances required. I
don’t know much about their manufacturing abilities, but I know they didn’t do a
lot of it and imported most things. I couldn’t find the tolerances needed for the
Harvard Mark I, an electromechanical computer, but I’m hesitant to believe that
they could have built that either. It’s hard to know how precise manufacturing
techniques were back then, but one of the best clues we have is the Antikythera
mechanism. It uses hand cut gears that are surprisingly precise, but still probably
not good enough for a mechanical computer. Small inaccuracies in the gear trains
would add up, and this is evident in the Antikythera mechanism. It would be even
more pronounced in a room sized contraption and would almost certainly prevent
any useful calculations from being performed.
If the Romans couldn’t do it mechanically, they would have needed a
semiconductor. When most people think of semiconductors, they think of clean
rooms and millions of dollars of machinery. However, that kind of equipment is
only needed for high performance semiconductors used in modern integrated
circuits with high speed, high efficiency switching. It turns out that
naturally occurring semiconductors are actually quite common. Minerals like
zincite, bornite, and carborundum will work. However, the best mineral to use is
lead sulfide, AKA galena. It be used without any modification directly after mining.
It’s got a band gap of about 0.4 eV. Ancient societies knew all about galena, and the
Egyptians used it as makeup.
They could have easily made a cat’s whisker diode by using a small piece of
springy wire to touch a point on the galena crystal, creating a crude and unstable
metal-semiconductor junction called a Schottky barrier diode. Current will flow
from the metal into the galena, but not the other way around. This is the same
technique that was used in early crystal radio receivers. POWs in World War II
used the oxidation on razer blades as a semiconductor and a safety pin to create a
diode so they could build receivers to keep up to date with news on the war. It took
a lot of patience to find a perfect spot on the blade that would work, and likewise it
would take time to poke the galena with the wire in different spots to find a place
that would act as a diode.
If they could have built a diode, could they have built a transistor? The first
transistor that Bell Labs built (although not the first transistor ever built) was point
contact and looked pretty similar to the cat’s whisker diode.
Instead of a single point, they had two, each formed by the contact of the edge of a
piece of gold foil onto a hunk of Germanium. A simpler version of this can be done
by basically building a cat’s whisker diode but using two springy wires touching
two different spots on the galena. So couldn’t the Romans have just modified their
diodes to make transistors? In my opinion, no. When Bell Labs was experimenting
with transistors, they tried making a galena cat’s whisker version and ran into some
problems. To being ―transisting‖, the whisker tips had to be closer than 0.1 mm.
They also found that you had to use freshly cleaved galena surfaces and any
humidity would interfere. They had to make extremely sharp whiskers by
dissolving the ends with electrolysis. Now, I don’t want to underestimate the
Romans. Maybe they could have trained workers to be that precise or come up with
some other way of solving the problem. But we’re going to take it easy on them
because there’s a better way to get around the problem of no transistors.
The Romans knew how to make wire and also knew how to work iron. So now the
question is, can you build a computer using only diodes, wire, and iron? Well, prior
to 1953, no computers used transistors. The Romans knew how to work glass, but
it’s unlikely they could have manufactured vacuum tubes. While a lot of early
computers did use vacuum tubes, they often also relied on diode logic. There are
two major problems you have to solve with diode logic. First, diodes have a voltage
drop across them, which means you need to amplify the signal every so often. Early
designers solved this problem using transistors as amplifiers. The second problem is
that you can’t design a NOT gate (an inverter) using only diodes. Designers got
around this problem also by using transistors (or vacuum tubes). So how could the
Romans have done it without transistors? Well, you can build an inverter using a
transformer by simply flipping the secondary output wires around. A transformer is
just a square iron ring with wire wrapped around each side. You have to use
discrete pulses rather than continuous logic levels, but that’s how everyone did it in
the 40’s and 50’s. To solve the amplification problem, you can use a relay. You can
make a relay using only iron and wire, but they’re often small, intricate devices and
they have moving parts. I think if they recruited Roman jewelry makers and scaled
the size so it was reasonable to work with, they could have produced relays. There
are some really impressive pieces of Roman jewelry that have been found. The
image is too large to embed here, but take a look at the chain on this piece.
They also would have needed to make memory, a way to preserve the state of the
machine. The obvious candidate here is core memory. Most core memory was made
using ferrite, but regular iron can be used. I won’t go into detail here on how core
memory works because Wikipedia has a good article on it. If you’re not familiar, I
recommend checking it out. It’s a really neat idea. Incidentally, you can also make
logic using ferrite cores, like the Elliot 803 did, so that could be useful for
supplementing (or even replacing) diode logic.
The last, and perhaps most important thing you need for a computer is electricity!
We know that the Baghdad Battery existed back then, but it’s highly unlikely that a
plausibly large array of them could power this hypothetical Roman computer.
Instead, they would have had to use a generator. This is probably the most difficult
part of this hypothetical computer. To turn a water wheel into a generator, they
could have used a configuration like this:
But you need a magnet for that. Basically the only magnet they would have had
access to is Lodestone. There are a couple of ways they could have made a better
magnet. From Wikipedia:
Heating the [iron] above its Curie temperature, allowing it to cool in a
magnetic field and hammering it as it cools. This is the most effective method
and is similar to the industrial processes used to create permanent magnets.
Placing the item in an external magnetic field will result in the item retaining
some of the magnetism on removal. Vibration has been shown to increase the
effect. Ferrous materials aligned with the Earth’s magnetic field that are
subject to vibration (e.g., frame of a conveyor) have been shown to acquire
significant residual magnetism.
Stroking: An existing magnet is moved from one end of the item to the other
repeatedly in the same direction.
By iterating the process several times to make successively stronger magnets, the
Romans could probably have made some magnets good enough for a generator.
It’s important to note that I’m not a historian; I’m a computer engineer (who was
trained using modern techniques, at that). So this is all speculation. I think if you
traveled back in time to the Roman Empire and told them how to manufacture this
stuff, you could plausibly create a very modest computer. My main concern is
powering the device, I still don’t know if that would work well enough. But there’s
only one way to find out: Experiment…
Are you an expert at Roman history or the kind of engineer who remembers using a
mercury delay line? I’d love to hear about other tricks they could have used!
Come a Long Way Baby!
