Granted: 1994-10-18
Abstract: ABSTRACT OF THE DISCLOSURE      A system for transmitting a comb of radar signals.          The invention includes a phase shifter for shifting the phase of an input carrier signal.  A frequency modulation signal is adjusted in amplitude by an attenuator 16 and input to a balanced mixer 14.  The balanced mixer 14 mixes the input carrier signal with the attenuated frequency modulation signal.  A summer 20 combines the output of the phase shifter 12 with the output of the balanced mixer 14.   The system 10 of the present invention provides an inexpensive means of generating and receiving a complex of illuminating signals having a spread spectrum consisting of lines (teeth) of carrier frequencies with controllable power.  The system 10 is agile in that the power levels and the spectral positions of the teeth may be varied.

Abstract: A system (8) is provided for weighing and monitoring flow from multiple fluid sources (76) into a flow system (10) wherein incoming fluid is received in a weighing bag (80) att-ached to a control system for monitoring the amount of fluid passed through the weighing bag (80) and for preventing admis-sion of air into the flow system (10). An alarm attached to the weighing bag (80) warns when fluid in the weighing bag (80) is approaching empty, so that the fluid in the weighing bag (80) can be replenished from the fluid source (76) before the weigh-ing bag (80) runs dry. If fluid in the weighing bag (80) is not re-plenished, the system automatically shuts down. The fluid pump (72) can be absolutely calibrated using the controlled admission of known amounts of fluids into the weighing bag (80) so that the amount of fluid introduced into the flow system (10) through the weighing bag (80) can be calculated automatically.

Title: Digital communication system using superposed transmission of high speed and low speed digital signals
Inventor: SUGIYAMA TAKATOSHI
IPC: H04N21/647
Filed: 1992-11-25
Granted: 1998-09-29
Abstract: A digital communication system using superposed transmission of high and low speed digital signals capable of transmitting superposed high and low speed digital signals through an identical frequency band efficiently by increasing a simultaneously transmittable number of channels in the low speed digital signals, while achieving the practically reasonable bit error rate performances for both the high speed digital signals and the low speed digital signals. In this system, the low speed digital signals are transmitted in a form of spread spectrum signals and the high speed digital signals are cancelled out from the superposed transmission signals in obtaining the output low speed digital signals by using the phase inverted replica of the high speed digital signals to be combined with the superposed transmission signals, so that it becomes possible to increase a number of channels for the low speed digital signals, while achieving the practically reasonable bit error rate performances for both the high speed digital signals and the low speed digital signals.
Patent CA-2085269-C (CA)
Title: Expandable time slot interchanger
Inventor: AARON CALVIN
IPC: H04Q11/08
Filed: 1992-12-14
Granted: 1997-05-06
Abstract: A transmission scheme serially propagates time slot data to a plurality of TSI modules with time slot data contained in one TSI frame being serially transmitted from module to module in a daisy-chain technique. A dedicated outbound transmission bus transmits the frame of data from one module to a dedicated inbound transmission bus of another module. The outbound and inbound data buses are connected by separate buses on a backplane which is coupled to each of the TSI modules. Preferably, the TSI modules do not transmit selected ones of the stored data to end destinations until the last TSI module has received the frame of data so that all modules can begin the transmission in time synchronization. Maximum transfer data rates can be achieved since undesired transmission line characteristics or disruptions are minimized by the use of dedicated input and output transfer buses between the modules. Additional modules can be added without disrupting the transmission data rate between existing modules, thereby permitting a growable TSI facility without adversely impacting the data transmission rate between modules.
