Intrinsically Safe Telephone
View pageUS Patent:
51366304, Aug 4, 1992
Filed:
Jul 13, 1990
Appl. No.:
7/553538
Inventors:
Brian H. Breneman - Reading PA
Bruce Dale - Robesonia PA
Bruce Dale - Robesonia PA
Assignee:
Gai-Tronics - Reading PA
International Classification:
H04M 904
US Classification:
379 64
Abstract:
An intrinsically safe telephone as provided for use in hazardous areas. The telephone includes a single line instrument located in the hazardous area which, in turn, is coupled by a two-wire transmission path to a shunt diode barrier and a telephone line interface located in a safe environment. The telephone line interface reduces power of incoming ringing and audio signals. The telephone line interface further includes an off-hook indicating circuit which senses when the single line instrument is off-hook. The intrinsically safe telephone is useful in all hazardous environments as classified by the National Electrical Code and requires no explosion-proof housing.
Watchdog Timer
View pageUS Patent:
50480170, Sep 10, 1991
Filed:
Dec 29, 1988
Appl. No.:
7/291500
Inventors:
Brian H. Breneman - Hellam PA
International Classification:
G06F 1132
US Classification:
371 163
Abstract:
A watchdog device for monitoring control signals from a computer being used to control an operating system, is disclosed; said device having sufficiently low operating power requirements so that it is compatible with the power requirements of a series connecte LED indicator. The device is thereby capable of displaying a visual indication of its output status by activating an LED indicator which may be rack mounted or integrated into the device. In addition, the timer disclosed provides an adjustable timer interval which allows its adaptation to applications having widely differing time-out requirements. Depending on the requirements of the application, the adjustability is accomplished using a variable resistor, capacitor, or inductor for short timer intervals, or an oscillator driven frequency divider circuit for long timer intervals. Further, for steady state or non-periodic control signals, the device has no timing circuit, but provides an electromechanical relay to control the LED indicator and thereby provide a visual indication of control status.
