Title: Oxygen monitoring devices
Inventor: SEGER JOHN L
IPC: G01N27/407
Filed: 1993-06-01
Abstract: OF INVENTION An oxygen sensor having a main body member with an interior chamber, made from material which is an oxygen ion conducting solid electrolyte when at specified temperatures. Electrodes made from material which is porous to oxygen molecules axe positioned opposite each other on the main body member, within the interior chamber and on the outside of the main body. Via a port which extends through the main body, changes in the absolute pressure of gas to be tested in the environs of the outer electrode are transmitted to the gas in the environs of the inner electrode. As a result of reference gas being introduced into the interior chamber of the main body through an orifice at a pressure sufficient to maintain the rate of flow at its critical (and therefore constant) rate of flow, the environs of the inner electrode are occupied by reference gas and a flow of gas results, through the main body member from the region of the inner electrode and out through the port. In optional embodiments, only a portion of the test gas directly impinges upon the outer surface of the outer electrode to minimize it being cooled, the main body member is heated to specified temperatures, means are provided to ensure a flow of test gas past the sensor, and/or the outside electrode periodically is exposed to reference gas to calibrate the sensor for cell constant.

Title: High Impedance Plasma Ion Implantation Method and Apparatus
Inventor: SCHUMACHER ROBERT W
IPC: H01J37/32
Filed: 1993-11-03
Abstract: A high dose rate, high impedance plasma ion implantation method and apparatus to apply high voltage pulses to a target cathode (6) within an ionization chamber (2) to both sustain a plasma in the gas surrounding the target, and to implant ions from the plasma into the target (6) during at least a portion of each pulse (18). Operating at voltages in excess of 50kV that are too high for the reliable formation of a conventional glow discharge, the plasma is instead sustained through a beam-plasma instability interaction between secondary electrons emitted from the target (6) and a background pulsed plasma. The voltage pulses are at least about 50kV, and preferably 100kV or more. Pulse durations are preferably less than 8 microseconds, with a frequency in the 50-1,000Hz range. The preferred gas pressure range is 1x10 -4 - 1x10 -3 Torr; auxiliary electrodes (24a, 24b) can be used at the lower pressures to provide sufficient seed electrons for initiating a plasma, which is sustained by the beam-plasma instability interaction.

Abstract: ABSTRACT   A  catheter  (10)  with  several  independent  lumens (36,40,44,48) extending longitudinally through the catheter (10) for accepting probes (82) and for introducing fluid through the  catheter  (10)  and  into a  body cavity  is disclosed.     The  catheter  outer  body  (12)   has  a cross-sectional maximum outer dimension.  The first lumen (36)   is  circular   in   cross-section,   and   has   a cross-sectional dimension of approximately half the maximum outer dimension of the catheter body (12).  The first lumen (36) is capable of accepting various probes (82), as well as allowing simultaneous fluid flow through the lumen (36). The second lumen (40) is crescent-shaped in cross-section and occupies at least a quarter of an arc around the cross-section  of  the  catheter  body  (12).    The  large cross-section of the second lumen (40) allows for a high fluid flow rate through the lumen (40).  The third lumen (44) allows for inflation of an inflation balloon (when present), and the fourth lumen (48) allows for the passing of a portion of an instrument along the length of the lumen.  A probe (82)  (for use with the catheter (10) is also disclosed.   The probe transducer portion  (92)  is constructed of a crystal hollow cylinder  (94)  with an inside lead (96) attached to the inner surface (106) of the crystal cylinder (94).  One end (116) of the outside lead (98) is positioned close to the outer surface (108), in a plane (120) tangential to the outer surface (108), and is coupled to the outer surface (108) of the crystal cylinder (94)  by  a  thin  sputtered  layer  (104)  of  conductive material.  The probe transducer (92) also includes a layer (100) of acoustically absorbing material on the proximal end  (124)  of  the  crystal  (94),  and  layer  (102)  of acoustically coupling material on the distal end (126) of the  crystal  cylinder  (94).    The  transducer  element simultaneously generates an axially oriented signal beam (144) at one frequency and a radially oriented signal beam (146) at a different frequency.  The signal beams (144,146) are analyzed to calculate the blood flow area (A) and the blood flow velocity (V), the product of which is the blood flow rate (Q).

Title: Power control module for computer monitors
Inventor: HEINEMAN LEE J
IPC: G06F1/32
Filed: 1994-08-31
Abstract: ABSTRACT      A self-contained power control module for controlling power to the peripheral output devices of an electronic data processing system.  The power control module automatically interrupts power to  the  peripheral  output  devices  of  the  system  after  a predetermined interval has elapsed without detection of data input, and restores power to the peripheral output devices upon detection of data input.  A pulse detection circuit, connected to the peripheral input devices, monitors the peripheral input devices for data pulses.  A timing module, connected to the pulse detection circuit, is reset upon the detection of a data pulse. After a predetermined interval has elapsed without detection of a data pulse, the timing module outputs a control signal to two switches.  A power switch, disposed between the power supply and the peripheral output device, controls power to the peripheral output device in response to the control signal from the timing module.  A data switch, disposed between the peripheral input device and the microprocessor of the data processing system, controls input of data to the microprocessor in response to the control signal from the timing module.

The container (22) also has a second material (20) disposed therein, which is adapted to be heated above a predetermined period of time. The second material (20) can be an inner layer of the container (22), can be applied to a microwave transparent sheet (62) surrounding the first material, or can be embedded in a silicone tube (63) surrounding the first material. The second material is in a heat transfer relationship with the first material. While the dispenser is being subjected to microwaves, the second material converts the microwave energy into heat and transfers the heat to the first material. The first material then changes to a state of low viscosity and can be dispensed from the container (22) through the outlet (24).
