Sample Products Designed by EDA

A dual-accelerometer milling-machine tool breakage prevention monitor -- used in the automobile manufacturing industry.    Internal technology uses TI- TMS 320 DSP and isolated interfaces. A companion custom RS485 multidrop network interface box assures over 80 volts of common mode for large machines on an expansive factory floor.          ED-Chips1.jpg (62673 bytes)              ED-RS485Net.jpg (21896 bytes)   

   ...... a wireless remote entry and security system for Bonanza aircraft (300MHz):

 EDA-SmtLock.jpg (13234 bytes)  

.... and a service truck       monitoring  system for job-tracking and driver auto-mileage tracking in service fleets. Up to three weeks of collected data is automatically and wirelessly uploaded to the host site without air-time fees using custom-designed short-range FCC-ISM frequency-band binary FM radios. Custom designed drive-shaft and door sensors provided raw vehicle information.

            Here is a sixteen Channel EMG system designed for Motion Lab Systems, Inc. for use in hospital gait labs. A close up of the custom dry-electrodes with internal active pre-amplifier is adjacent. A single miniature coaxial cable connects the patient-carried "backpack". This cable carries both power and multiplexed high-speed EMG data on a multi-MegaHertz carrier signal..

              Pmi210.jpg (12789 bytes) This prototype oximeter's 1/4 VGA LCD main screen displays: Pulse Rate, SpO2   and Respiration Rate.  Associated with each variable is a five-minute trend line.  The selectable Trend Screen displays SpO2 , Pulse Rate, Respiration Rate and the two vertical, thirteen segment bar graphs. The core processor is a Pentium class card.

... and an example of a larger medical instrument to control endoscopic surgery motor-tools. It had voice prompting and status reporting with six selectable languages. ed-endo1.jpg (36056 bytes)       EDA-XPS.jpg (21815 bytes)

.... A nautical industry product combined a GPS receiver and wireless signaling inside of water-proof wrist-radio cases to immediately sound an alarm when a "man-over-board" event occurred. The system would log the GPS coordinates at the time of the "event" and sound a horn alarm. Unused wrist-radios recharged while in the wall-unit.                                              EDA-LifeWatch.jpg (16202 bytes)

Custom plastic packaging can be modeled in a CAD package and then prototyped using Stereo Lithography Apparatus (SLA). An example of a remote controlled lamp dimmer switch prototype follows:

EDA can design into your product custom LCD displays and keyboards using snap dome switches, membranes or silicone rubber keypads. An example of custom LCD displays and a magnetic (Hall effect) keyboard is this prototype battery operated electronic bingo game. Proximity coupling was used to both charge its battery and download game data.
