Abstract: A comparator circuit for a switched resistive network, which may be combined with a transconductance amplifier, simultaneously and independently compares a plurality of input voltages to a reference voltage. The circuit comprises a current splitter having a current input, a plurality of comparator outputs, and a corresponding plurality of voltage inputs that control the fraction of the input current available at each comparator output. A reference output of the current splitter is provided as an input to a current mirror, and each of the comparator outputs of the current splitter is connected to a corresponding output of the current mirror. The current available at each of the current mirror outputs is a function of the reference input provided from the current splitter. The comparator circuit needs only one bias input and one reference input. The inclusion of a second biasing device with an associated mirror device produces a transconductance amplifier combined with the comparator circuit. This combination minimizes the integrated circuit area required for transconductors and comparators on image processing chips.

Abstract: An improved mechanical system selectively locks the tester valve of an annulus pressure responsive tester valve in position for an indeterminate number of well annulus pressure cycles.  The tester valve can be closed upon demand. The forces which accomplish opening of the ball valve act across a power piston, but the forces which close the valve act across an actuating piston. The tester valve can be run into a well with an operating element of the tester valve such as a tester valve, in a first position such as a closed position. Upon reaching the desired depth within the well and setting of an associated packer system, well annulus pressure is then increased to a first level above hydrostatic pressure to move the power piston and thus move the tester valve to an open position. During a normal mode of operation, well annulus pressure can be cycled between hydrostatic pressure and the first level to open and close the tester valve. If desired, the tester valve may be placed into a "locked open" mode of operation wherein the well annulus pressure can be cycled between hydrostatic pressure and the first level, such as would be done to operate a pressure annulus device elsewhere in the testing string. To place the tester valve into the "locked open" mode, a second level of well annulus pressure, which is above the first level, is applied to the well annulus and then released. Reapplication and release of the second level of annulus pressure will enable a selectively actuatable load transfer assembly to close the associated ball valve and return the tester valve to its normal mode of operation.     A fluid transfer assembly is included within the power piston which is operable to transfer fluid across the power piston. The fluid transfer assembly includes a pressure relief valve and fluid restrictor which will transfer fluid in one direction across the power piston in an overpressure condition when the well annulus pressure is increased to a second level above the first level.  The fluid transfer assembly also includes an oppositely disposed check valve to allow unrestricted fluid flow across the power piston in the opposing direction during a release of annulus pressure. The tester valve also features a multi-range metering cartridge which is operable to meter fluid over a wide range of differential pressures. The metering cartridge provides an adjustable resistance flow path which permits fluid flow across the cartridge. The resistance of the flow path is adjustable by selectively diverting the fluid through a series of fluid flow resistors.  Resistance may be increased either by adding a number of flow resistors serially or by adding a single flow resistor which itself provides a greater fluid flow resistance.

Abstract: An ATM cell flow control apparatus includes interface sections for terminating transmission lines of two systems which constitute a redundant structure and to which identical cell sequences are supplied.  Each interface section includes a cell synchronization section, a cell buffer, a policing section, and a delay control section.  The cell synchronization section performs cell synchronization control of an input cell sequence and outputs the sequence in units of cells.          The cell buffer performs delay adjustment of each cell output from the cell synchronization section.  The policing section detects the cell interval between cells output from the cell buffer, and discards cells having a detected cell interval shorter than a predetermined cell interval.  The delay control section detects the phase difference between a cell output from the cell buffer of a self-system and a cell output from the cell buffer of the other system, and controls the cell buffer in accordance with the detected phase difference.
