As part of the overall 3 Corner Satellite (3CS) project within the University Nanosat Program, the development and
testing of a communications subsystem for the satellite was undertaken at New Mexico State University in conjunction with
the other team members. This report describes the overall satellite project and the details of the development of the flight radio
system for 3C5. This report also documents the preliminary design of the LabVIEW software for linking the university ground
communications network.

Patent Info.: Filed: 7 Jun. 1999, Patented 21 May 2001; US-Patent-Appl-SN-326717
Report No.(s): AD-A406396; PATENT-6 393 305; No Copyright; Avail: US Patent and Trademark Office
A method to authorize or authenticate a user of a wireless telecommunication system (32), and includes steps of (a)
selecting a word at random from a set of reference words, or synthesizing a reference word; (b) prompting the user to speak
the reference word; and (c) authenticating the user to operate in, or through, or with a resource reachable through the wireless
telecommunication system, only if the users speech characteristics match pre-stored characteristics associated with the
reference word. In one embodiment the steps of selecting or synthesizing, prompting, and authenticating are performed in a
mobile station (10) having a speech transducer (19) for inputting the user’s speech, while in another embodiment at least one
of the steps of selecting or synthesizing, prompting, and authenticating are performed in a wireless telecommunications
network (32) that is coupled between the mobile station and a telephone network (35). In yet another embodiment at least one
of these steps are performed in a data communications network resource (38) that is coupled through a data communications
network (37), such as the Internet, and the wireless telecommunications network to the mobile station. The step of prompting
may include a step of displaying alphanumeric text and/or a graphical image to the user using a display (20) of the mobile
station.

Program Manager, Aircrew Integrated Systems (PM-ACIS) is developing a new helmet-mounted display (HMD)
technology based on scanning lasers. Under this program, Microvision, Inc., Bothell, Washington, has developed a scanning
laser HMD prototype for use with the Aircrew Integrated Helmet System (AIHS) Helmet Gear Unit - 56/P (HGU-56/P). As
part of a comprehensive laser safety evaluation plan, power measurements of the prototype system were made at the design
eye position for both normal and failure modes. For normal operation, right eye and left eye measurements of 1.48 and 1.58
microwatts were obtained. For total scanner failure, a value of 77 microwatts was obtained.

Future telemedicine systems will exploit mobile communications technology so that patients who are free to move around
at home or at work, or in emergency medical situations, can be monitored in a hospital. At present, the GSM mobile telephone
cellular network is limited to 9.6 kbps, but with the introduction of the third generation (3G) network, data rates of 144 kbps
will be available, giving scope for the transmission of much more biomedical data as well as voice and video data if required.
The paper discusses some of the issues involved and outlines the types of systems that will be viable with the new technology.
