Abstract: Accurate tuning of a satellite system's burst demodulator to a signal which is subject to frequency offset in the course of its transmission over the satellite link is achieved without the use of high precision oscillators at remote sites, or the transmission of a dedicated pilot tone. Instead, a dedicated high precision clock is used for the purpose of establishing both the outlink carrier and the return channel carrier. The modulation of the data on the outlink carrier is also derived from the precision clock source. At each remote station, the outlink channel is monitored to recover the high precision clock. This recovered clock is then used as a reference for generating the return channel carrier. The burst demodulator equipment at the master station monitors both the outlink channel continuous carrier and burst mode transmissions from the remote stations. Each of the continuous and burst mode carriers, having been transmitted through the satellite, will undergo the same frequency offset or modification, so that the frequency difference between the outlink channel carrier and the return link channel carrier will always be constant. The outlink channel carrier, which is available on a continuous basis, is used to derive a local oscillator frequency reference for establishing the burst demodulator's local oscillator reference.

Abstract: A programmable low voltage compressor circuit suitable for use with hearing aids is described. The compressor has a continuously variable compression ratio wherein the gain of the compressor may be programmably controlled over a wide range and the compressor may be powered from a power source as low as 1.1 volt. The compressor employs a variolosser wherein the gain is controlled by the ratio of the currents flowing out of first and second control terminals. A control circuit coupled to the variolosser controls the magnitude of the currents flowing out of the two control terminals. The control circuit includes a peak detector which generates a signal related to the peak positive envelope of the signal input to the compressor. A voltage to current converter is coupled to the peak detector for increasing the magnitude of the current flowing out of one of the control terminals of the variolosser as the voltage output of the peak detector increases. Furthermore, the gain and compression ratio of the compressor over a wide range is programmably controllable.

Abstract: A power control system for a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell site using code division multiple access spread spectrum communication signals. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna, transmitter and receiver and each cell-site also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to increases and decreases in received signal power. A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so as to arrive at the cell-site at a desired power level.

Date Sep. 17, 1992.A method of verifying that a safety valve, normally biased to a closed position and opened by hydraulic pressure applied thereto by a fluid supplied at a constant flow rate, is operating correctly within an oil well involves comparing reference and operating curves associated with the valve. The reference curve represents the hydraulic pressure over time applied to the safety valve to open the valve when the valve is operating correctly. The operating curve is prepared with the safety valve installed within an oil well and also represents the hydraulic pressure over time applied to the safety valve to open the valve. Any deviation between the reference and operating curves indicates a potential malfunction and, possible, a precise type of malfunction associated with the safety valve.

Abstract: A Parallel RISC computer system is provided by a multi-mode dynamic multi-mode parallel processor array with one embodiment illustrating a tightly coupled VLSI embodiment with an architecture which can be extended to more widely placed processing elements through the interconnection network which couples multiple processors capable of MIMD mode processing to one another with broadcast of instructions to selected groups of units controlled by a controlling processor. The coupling of the processing elements logic enables dynamic mode assignment and dynamic mode switching, allowing processors operating in a SIMD mode to make maximum memory and cycle time usage. On and instruction by instruction level basis, modes can be switched from SIMD to MIMD, and even into SISD mode on the controlling processor for inherently sequential computation allowing a programmer or complier to build a program for the computer system which uses the optimal kind of parallelism (SISD, SIMD, MIMD). Furthermore, this execution, particularly in the SIMD mode, can be set up for running applications at the limit of memory cycle time. With the ALLNODE switch and alternatives paths a system can be dynamically achieved in a few cycles for many many processors. Each processing element and memory and has MIMD capability the processor's an instruction register, condition register and program counter provide common resources which are used in MIMD and SIMD. The program counter become a base register in SIMD mode. In one embodiment all instruction registers are coupled to form a common broadcast path, and in an alternative embodiment, the ALLNODE switch is utilized as an alternative path for broadcast to all processors coupled by the interconnection network to be chosen as the system of choice. <IMAGE>
