6163568 Broadband, low power FM/FSK transceiver for wireless communications systems December 19, 2000
An FM/FSK Transceiver for a wireless communications interface is disclosed which employs an offset phase lock loop which is accelerated into phase lock by a sweep signal to avoid data degradation, and which includes a feed forward compensation to accommodate a broadband response from DC
5828822 Watchdog circuit for carbon monoxide monitors October 27, 1998
A microcontroller supervision circuit comprising an electronic control capable of causing a high-impedance on at least one external pin upon occurrence of a reset condition. A supervision circuit is coupled to the at least one external pin for detecting the high-impedance condition. Upon
5659125 Automatic calibration method for carbon monoxide monitors August 19, 1997
A method and apparatus to automatically calibrate a carbon monoxide detector placed in an environment having a known concentration of carbon monoxide. The monitor is placed in a calibration mode in which it reads the output signal from the sensor and normalizes the output signal to a
5586054 time-domain reflectometer for testing coaxial cables December 17, 1996
A time-domain reflectometry device and method are provided wherein TDR may be performed on active Ethernet systems. A crossover network provides proper impedance termination both for pulse information generated by the TDR and for DC path signals. If a potential collision is detected when
5548222 Method and apparatus for measuring attenuation and crosstalk in data and communication channels August 20, 1996
A termination control circuit is coupled to a far end of a cable. A modulated test signal is reflected back to a near end of the cable at a different frequency but at substantially the same level of attenuation as the test signal. Signal attenuation in the reflected signal is then me
5198805 Method and apparatus for monitoring a network and locating a node using signal strength calculat March 30, 1993
Disclosed is a system that monitors the signal strength of each transmission by a node on a LAN cable of a local area network and determines the location of the node sending the signal. This system has a monitor at each end of the LAN cable, with one of the monitors typically being l
