Title: Multiple user digital receiver apparatus and method with combined multiple frequency channels
Inventor: KELLEY EDWIN A
IPC: H03B28/00
Filed: 1992-04-21
Abstract: A digital receiver apparatus and method, designed for multiple simultaneous users, digitizes a received analog RF signal and performs multiple frequency translations of the signal so that desired stations are grouped into a common frequency band separate from the remaining stations.  This frequency band is then isolated, and the individual select-ed stations are digitally separated, demodulated and audio processed to provide multiple simultaneous outputs.  The frequency translations are preferably performed initially on a time multiplexed basis.  Isolated station separation is performed either by time multiplexing, or by the use of multiple phase or tan lock loops.

Patent CA-2077747-A1 (CA)
Title: Telephone call detecting circuit and a method of remotely accessing and testing a telephone
Inventor: COMFORT JOHN J
IPC: H04M3/24
Filed: 1991-03-15
Abstract: A telephone circuit is provided for distinguishing between a normal incoming telephone call and a test telephone call. A series connection of capacitor (C1), bell (2) and relay (13) is provided across the telephone line pair (1). The relay (13) is normally open so that a ringing signal appearing across the telephone line pair (1) does not cause the bell (2) to ring. The ringing signal is sensed by a ringing detector (15) which supplies an output signal to a processor (6). If the ringing signal is present for more than a predetermined time, such as three seconds, the relay (13) is caused to close, thereby enabling the bell (2) to sound. When the telephone is polled from a central station to cause it to undergo a self-test routine, a ringing signal is used which consists of a series of three ringing signals each lasting less than the predetermined time. Consequently, when such a ringing signal is received, the relay (13) remains open, and there is no audible ringing tone. The system thus enables a testing routine to be carried out by the telephone without causing the telephone to ring.
