Title: Sensor for measuring the concentration of a gaseous component in a fluid absorption
Inventor: NESTOR JAMES R
IPC: A61B5/145
Filed: 1987-07-13
Granted: 1992-05-26
Abstract: TAH:cp Abstract Apparatus and methods are provided for determining the concentration of a gaseous component in a fluid   A solid body of a natural or synthetic high polymer, which is permeable to the gaseous component, is exposed to the fluid, the polymer is exposed to infrared radiation, and the infrared absorption by the gas in the polymer is measured. In the preferred embodiment, a sensor is provided for making in vivo measurements of the concentration of CO2 in the blood.   The sensor includes an optical fiber which is nonpermeable to CO2 and substantially transparent at the CO2 absorption wavelength range, and a solid body of polymeric material at the distal end of the fiber which is substantially transparent to the absorption wavelength range and permeable to CO2.   An incident infrared signal is transmitted down the fiber, passes throught the body, is reflected off the distal end of the body, and the intensity of the return signal is measured by a detector.  The return signal is diminished in proportion to the concentration of the CO2 in the polymeric body. The sensor is disposed within a catheter and is positionable within the narrow blood vessels of the body for continuous real time monitoring of the carbon dioxide concentration of the blood.

Title: Vehicle anti-lock brake system
Inventor: ATKINS THOMAS M
IPC: B60T8/70
Filed: 1988-06-14
Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE    The present invention concerns a vehicle anti-lock brake control system which does not require the use of an auxiliary hydraulic pump and, in the preferred embodiment, is adapted to control only the rear brakes of a four-wheel vehicle.  The control system includes a normally open solenoid actuated isolation valve connected between the master cylinder and the rear wheel brakes, and a normally closed solenoid actuated dump valve connected between the rear wheel brakes and a fluid accumulator.  A computer control is connected to monitor the rear wheel speed and deceleration and, during braking of the vehicle, functions to control the application of hydraulic pressure to the rear brakes via the isolation and dump valves in order to prevent lock-up of the brakes.  In the event excessive rear wheel deceleration is detected during a vehicle stop, the computer control closes the isolation valve to hold pressure to the rear brakes at a relatively constant level. If, after the isolation valve has been closed, the difference between the actual rear wheel speed and a calculated theoretical speed ramp valve exceeds a predetermined slip threshold, the dump valve is selectively opened to reduce pressure to the rear brakes and correct the wheel slip condition.  The computer control is adapted to monitor several operating parameters while the system is in the anti-lock mode in order to determine whether additional pressure should be applied to the rear brakes by selectively opening the isolation valve.

Title: Control circuit with validity-determining arrangement
Inventor: RUTA JOSEPH W
IPC: H02H3/093
Filed: 1988-12-20
Granted: 1993-03-30
Abstract: ABSTRACT An arrangement is provided for checking the validity of a sensed-current signal from a current-sensing device. The sensed-current signal represents the current in a line. An associated control circuit utilizes the sensed-current signal to indicate or predict the presence of undesired overcurrent conditions. When such conditions may be present, the sensed-current signal is checked to determine if the sensed-current signal is valid; i.e., whether the sensed-current signal accurately represents the current in the line. If the sensed-current signal is invalid, no trip signal is generated to interrupt the current. If the sensed-current signal is valid, the control circuit generates a trip signal to control operation of a circuit-interrupting device. In a particular arrangement, the load on the current-sensing device is changed to determine if the sensed-current signal is valid. If the sensed-current signal is valid, the level of the sensed-current signal remains in a valid range and the overcurrent-detection circuit issues the trip signal. If the sensed-current signal is invalid, the level of the sensed-current signal changes. In response, the control circuit does not issue the trip signal and is reset to an initialized mode to monitor for a valid overcurrent condition in response to the sensed-current signal. In a specific arrangement, the current-sensing device is an iron-core transformer which saturates at high current levels.

Abstract: METHOD FOR CONNECTING DEVICES ON AN INTEGRATED      CIRCUIT SUBSTRATE TO A METALLIZATION LAYER     ABSTRACT OF THE DISCLOSURE         A method for connecting devices on an inte-grated circuit substrate to a metallization layer, where-in a thin layer of a dielectric material is deposited on the substrate,  and openings are formed in the di-electric layer wherein electrical connection is to be made to the substrate.  A metal barrier layer then is deposited selectively in the openings of the dielectric layer, the barrier layer completely covering the exposed portions of the substrate.  A pillar metal layer then may be deposited as a blanket coating over the dielectric layer and over the portions of the barrier layer covering the exposed portions of the substrate.  The pillar metal layer is etched for forming metal pillars extending from the exposed portions of the substrate.  The sub-strate then is planarized by depositing a dielectric layer and etching it back for exposing the pillars for coupling to a later deposited metallization layer.

Title: Method and device for the digital transmission of information in short-wave radio networks
Inventor: WIDMER HANSPETER
IPC: H04K3/00
Filed: 1989-03-31
Granted: 1992-11-24
Abstract: Abstract For the purpose of channel condition estimation at the receiver end, a reference signal (fq(t)) is added to and is transmitted with the data signal (fi(t)) containing the actual information.  The addition of the reference signal (fq(t)) to the data signal (fi(t)) is effected by means of a quadrature modulation with the reference signal on the Q-level and with the data signal on the I-level, the envelopes being selected so that the value of the complex envelope is constant.  The receiver has a function stage for preprocessing the receive signal, for quadrature detection of the data signal elements and reference signal elements (yi) and b(i) respectively, for selection of the data/reference signal and for estimating the channel condition.  This permits the operation of non-linear transmitter final stages and a maximum energy output from the transmitter, and the requirements of the short-wave range such as very low signal-to-noise ratio and signal interference ratio, fading, slightly drifting local oscillators and time bases, as well as high noise burst frequency are taken account of in an optimum manner.  In addition the send signal has a narrow bandwidth and a low sensitivity to bit slip, which increases the connection probability and the robustness of the transmission.

Inventor: NEWMAN KENNETH R
IPC: E21B19/22
Filed: 1989-06-23
Granted: 1992-06-30
Abstract: ABSTRACT    A method of inserting a well service tool for operating a coiled tubing which avoids the high and/or remote mounting of the heavy coiled tubing injector drive mechanism is disclosed.  The method comprises assembling the well service tool within a closed end lubricator, mounting the lubricator or the wellhead and lowering the tool into the wellbore to a distance whereby at least a portion of the tool is adjacent the pipe rams of the wellhead.  The pipe rams are then closed against the tool to effect a fluid tight seal and to hold the tool in position within the wellhead.  The lubricator is then removed and the coiled tubing and injector drive mechanism are connected to the tool and wellhead, respectively. the pipe rams can then be released and normal coiled tubing operations carried out.  The method offers the additional safety advantage of permitting pressure testing at each stage of the insertion process. Retrieval of the tool can be effected merely by reversing the process.
