摘要： A coherent phase shift keyed demodulator [Figures 1, 2 (14); Figures 9-12] provides improved performance and simplified circuitry through the use of a reference vector signal generator [Figures 2, 10 (78)] which employs an intermediate reference vector (V2) generated from the phase [Figures 2, 9 (60, 62)] of an incoming carrier signal which, under certain conditions, is reversed in phase prior to being combined with a previous value (VR old ) of the reference vector to generate an updated reference vector signal (VR new ). The demodulator also includes apparatus [Figure 10 (66)] to perform concurrent carrier detection and bitsynchro- nization operations.

摘要： The invention provides a dual mode meter reading apparatus including a first dial register encoder (36) and a second meter pulse encoder (38) both responsive to the measuring element (14) of an integrating meter. Electronic data registers (60, 61) store both non-volatile dial totalized readings and higher resolution pulse augmented readings encoded by the first and second encoders, respectively. Comparison means and a selective logic readout of the two meter readings reduces erroneous meter reading outputs.

摘要： A microprocessor-based coherent phase shift keyed demodulator [Figure 1 (14); Figure 2] determines the phase of an incoming carrier signal (30) by analyzing zero-crossings (46) of the carrier derived by polarity sampling (38) of the carrier. The polarity samples (43) are initiated by sample pulses produced in bursts (37), with each burst being triggered by a single microprocessor (39) interrupt. The sample rate (l/m) within a burst is an exact multiple of the microprocessor clock frequency and is on the order of the basic microprocessor instruction time.

摘要： The invention provides a communication system including a remote terminal (LMT 1, 2, etc.) at each customer location which contains a role code identifying the remote terminal as an end device and a plurality of address codes. A plurality of signal repeaters (R1, R2, etc.) are each connected with certain of the remote terminals through a distribution network (32). Each signal repeater contains stored route and role codes as well as a unique address code allowing each signal repeater to be additionally addressed as an end device. A central station (12) produces an outgoing communication signal intended for at least one end device. A communication link (20, 21) couples the central station to the power distribution network. The communication signal includes a route code identifying a signal path to the end device, a role code identifying the first device in the identified route, an address code and a message code. Upon receipt of the communication signal by a signal repeater which is not the intended end device, the received route and role codes are compared to the stored route and role codes. If there is a match, the signal repeater removes its role code from the communication signal, inserts the role code of the next device in the identified route and retransmits the signal. The signal is continually modified and retransmitted until the message code is received by the intended end device.

摘要： A dual threshold method and apparatus [Figure 10 (109, 111)] is used in a coherent phase shift keyed demodulator [Figure 2 (14)] to distinguish situations in which an incoming carrier signal (30) is expected from those open ended conditions when a receiver is active, but when an incoming signal is not imminently expected. The use of a lower threshold [Figure 10 (111-1)] permits more rapid detection and demodulation of a valid carrier signal by utilizing a standard which is less strict to determine the presence of a valid carrier signal when an incoming carrier signal is expected.

摘要： A time diversity carrier signal sampler utilizes a shift register [Figs. 6, 7 (70); Fig 8 (170)] in conjunction with a timer (190) and a plurality of phase samples [Fig. 7 (61, 62, 63); Fig. 8 (196, 197, 198)]. The instantaneous logic level of each phase is measured on a time diversity basis in orderto avoid the disadvantageous affects of noise pulses [Fig. 5 (54, 55)] which can occur coincidently on all three phases. The resulting carrier signal data is then provided [Fig. 8 (199)] to a microprocessor [Fig. 7 (80); Fig. 8 [(180)] for subsequent analysis and phase characteristic determinations. By judiciously selecting the sample and clock frquencies of the shift register, the sampling frequency for each phase and the time between sampling each of the phases can be preselected.
