Title: Gas monitor circuits
Inventor: JONES GARETH J
IPC: G01N27/49
Filed: 1986-10-17
Granted: 1990-12-11
Abstract: ABSTRACT OF THE DISCLOSURE          Circuits are described in which the sensing and the reference electrodes of a gas sensor housed within a gas monitor are connected together through the source and the drain of a field effect transistor (FET). The gate of the FET is connected to a power source to apply a first voltage to the gate when the monitor is operational and a second voltage, which is preferably zero, when the monitor is not operational, the resistance between the source and the drain  of the FET being low when the second voltage is applied to the FET gate so that the sensing and reference electrodes are connected together in a short circuit. When the first voltage is applied to the FET gate, however, the short circuit is effectively broken. The circuit has output lines leading to an output device, e.g. for displaying information or an alarm. A resistor of large resistance is connected between the two output lines and, when a gas is sensed a large voltage change occurs across the resistor which can be used directly, i.e. without an intervening amplifier, for driving the output device. A further, small resistor is connected between the reference electrode and the sensing electrode to provide noise immunity to the circuit.

Title: Peripheral controller and adapter interface
Inventor: LEWIS RICHARD P
IPC: G06F13/28
Filed: 1988-06-02
Granted: 1992-12-08
Abstract: PERIPHERAL CONTROLLER AND ADAPTER INTERFACE               ABSTRACT OF THE DISCLOSURE      In a computer system, each of several peri-pheral devices communicates through an associated adapter with a controller.  The controller sequentially establishes direct memory access data transfers between main memory on a system bus and individual peripheral devices.  A sequencer establishes individual cycle times during which each adapter and an associated direct memory access controller is able to complete a DMA transfer.  The adapter is conditioned for DMA and other data transfers by control signals from the controller.  A demand signal is asserted by the adapter only when the buffer memory of the adapter is prepared to service the DMA transfer.  The sequencer responds to the demand signal to generate a request for a DMA transfer during which a predetermined, limited amount of data is transferred in a DMA operation. During start-up, the adapter responds to initial control signals to provide an identifier to the controller so that the controller is able to fetch the software required to communicate with the adapter.

Title: Double-acting hydraulic piston-and-cylinder device
Inventor: HORVATH EDUARD
IPC: A61F2/68
Filed: 1988-09-21
Granted: 1992-11-03
Abstract: ABSTRACT OF THE DISCLOSURE        A double-acting hydraulic piston-and-cylinder unit adapted to constitute a damper for movements in a human joint prosthesis has a boot sealingly connected to the cylinder and the piston rod to receive the hydraulic fluid under pressure as the hydraulic fluid is displaced from one or the other of two cylinder chambers upon displacement of the piston rod.  The boot has a conically widening region or segment sealingly secured to the rod and adjoining the cylindrical segment of the boot surrounding the cylinder in a transition segment formed as an outwardly convex bulge and designed to ensure that initial inward movement of the piston rod will give rise to a plate membrane deformation of the elastic boot while only further displacement will result in a rolling action of the membrane.  This ensures a generally cylindrical uniform configura-tion of the boot in all positions of the rod as is essential for effective use in a prosthesis.
