Title: Microprocessor-based controller
Inventor: HOGLUND STEVEN R
IPC: F25B30/02
Filed: 1993-06-17
Abstract: A controller for a gas heat pump system wherein the controller has a variable capacity control capability that responds to thermostat output signals.  The variable capacity controller computes real-time performance parameters at variable capacity heating/cooling load conditions of the gas heat pump system.  A defrost controller calculates a maximum heat pump operating time period between successive defrost cycles and a minimum heat pump operating time period of each defrost cycle, during a heating mode of the gas heat pump.  Such values are calculated as a function of sensed time, temperature and variable capacity operating conditions which are calculated by the variable capacity controller.  The controller preferably has a manual mode for verifying correct operation of each actuator of the gas heat pump system, as a function of a sequenced input signal, while the gas heat pump system is in a shutdown mode.  The manual mode control also computes and generates an output signal for controlling each actuator to achieve efficient operation control of the gas heat pump system in various operational states, based upon predetermined operating parameters.

Title: Method for transferring information using modems
Inventor: SCOTT ROBERT E
IPC: H04B3/23
Filed: 1993-11-04
Abstract: A Method for Transferring Information Using Modems Abstract A modem (38)'s data reception rate is increased by decreasing the amplitude of the signals (34) transmitted by the modem (38). Decreasing the amplitude of the transmitted signals (34) reduces the amplitude of the resultingechoes, and thereby reduces the residual echoes that remain after echo cancellation. Reducing the residual echoes permits increasing the data reception rate. Decreasing the amplitude of the transmitted signals (34) also involves decreasing the data transmission rate; however, asymmetrical data transfer rates are acceptable for many modem applications.

Title: Manually changeable displays
Inventor: BAILEY WILLIAM M
IPC: G09F9/302
Filed: 1993-10-15
Abstract: Abstract of the Disclosure Two thin sheets (10, 11) of material have slits to define coplanar flaps (12AA-12GG and 12A-12G) that are configured and arranged in conformity with segments of a segmental display such as a seven-seg-ment digital display.   The layers are superimposed such that corresponding segments are superimposed. The layers have contrasting colors.  Applying a force against a typical overlying flap (12AA) in a segment causes the overlying (12AA) and underlying (12A) flaps to deflect in the same direction for the outer edges (22, 23) of the flaps to pass each other.  When the force is removed the flaps restore to positions that are substantially coplanar with the layers in which they are formed.  When the flap (12AA) in the overly-ing layer is coplanar with its layer that flap and, hence, the segment (A) is not visible because there is no contrast between the flap and the layer being viewed.  When the flap (12A) of the underlying layer is caused to switch over the flap (12AA) in the over-lying layer there is contrast between the flap and the overlying layer so the segment represented by the flap is visible.

Abstract: TITLE: Drift Free Low Noise Composite Amplifier and Method of Operation Thereof INVENTOR: Larry Douglas Coulson ABSTRACT OF THE DISCLOSURE A composite amplifier includes a discrete active gain  element with a feedback circuit that provides for low drift and low offset, but which also has low noise, short settling time and high bandwidth. This  is  accomplished  in  part  by  providing  an attenuator in the feedback circuit and by providing a voltage source for the source of the discrete active gain  element.  The  feedback  circuit  is  connected between the gate and the source of the active gain element and is responsive to a change in voltage at the gate to supply a voltage of equal but opposite magnitude to the source. The source has an impedance whose Johnson noise is less than the noise of the active gain element. A differential amplifier in the feedback is constructed in multiple stages with a first stage having lower gain than a second stage.

Title: A diagnostic catheter with memory
Inventor: YELDERMAN MARK L
IPC: A61B5/1495
Filed: 1992-09-29
Abstract: A catheter assembly having a catheter (100) with at least one transducer (110) associated therewith for directly measuring physiological parameters of a patient or measuring an amount of a parameter indicative of a physiological condition of the patient and a memory (102) which resides at a predetermined location on said catheter (100). The memory (102) contains encoded calibration information for calibrating the transducers (110) and encoded patient specific information which can be accessed by an external processing system to which the catheter assembly is connected for processing. The memory (102) is further designed such that disconnection of the catheter assembly from the external processing system does not cause values stored in the memory to be lost so that the patient specific information need be reentered into the memory when the catheter assembly is reconnected to the same or another external processing system. By so providing the catheter assembly with memory (102), information for factory calibration, patient calibration and historical patient data may be stored with the catheter (100) for ease of use.      The data in the memory (102) may also be coded to prevent easy replication of the catheter (100) by a competing manufacturer.

Filed: 1992-10-08
Abstract: A system and method for controlling transmission signal power in 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. A transceiver using the power control system is also disclosed. 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 that mobile unit transmitted signals arrive at the cell-site at a desired power level.

Abstract: A peel-away endoscopic retrograde cholangio pancreatography catheter and a method for using the same is provided.  An endoscope having a passage therethrough is introduced into the mouth of a patient and is guided through the patent's gastroentral tract until an opening at the distal end of the endoscope is in close proximity with the papilla of vater leading to the common bile and pancreatic ducts.  A peel-away ERCP catheter is provided which may be guided through the lumen of the endoscope until the distal tip of the catheter emerges from the opening at the distal end of the endoscope.  The distal end of the catheter may be guided through the sphincter of oddi and into the common bile or pancreatic duct.  A radiopaque dye may be injected through the catheter, into the duct.  Additionally, a guide wire may be guided into the common bile or pancreatic duct through the catheter.  Thereafter, the catheter may be easily removed without disturbing the placement of the guide wire by pulling on knobs attached to tabs at the proximal end of the catheter while the proximal end of the guide wire is held in place. The force applied to the catheter tabs causes the catheter to split longitudinally along two longitudinal grooves cut into the body of the catheter.  Thus, the catheter peels-away from the guide wire without displacing the guide wire. Simultaneously, the pulling force on the tabs splits the catheter away from the guide wire while pulling the catheter up the guide wire.  Additionally, a biliary stent can be pushed into the duct using a second peel-away catheter which may then be removed in accordance with the method of the present invention.

Title: Fused beryllium-zirconium brazing process
Inventor: DOWNIE GERRY
IPC: B05D7/24
Filed: 1994-04-22
Abstract: A process for brazing zirconium alloy elements to zirconium alloy nuclear fuel sheaths is taught. The process includes applying an initial layer of beryllium to the surface of the element and heating the element to form a fused beryllium-zirconium alloy layer on the element. The element is then placed on a fuel sheath and once again heated to allow the alloy to flow to fill the space between the element and the sheath. The initial layer of beryllium can be applied to the element by use of a beryllium containing brazing paste or by vapour deposition. The present invention provides a good braze while avoiding the variable results obtained using previous brazing methods.

Title: Enhanced yield platelet collection systems and methods
Inventor: BROWN RICHARD I
IPC: B04B7/08
Filed: 1993-03-23
Abstract: Systems and methods for separating a suspension of plasma and platelets from whole blood rotate a chamber (58) about an axis (62) to create within the chamber (58) a low-G zone radially close to the axis (62) and a high-G zone (66) spaced radially further from the axis (62) than the low-G zone (64). The systems and methods introduce whole blood into an inlet region (68) of the chamber (58) to initiate separation of red blood cells toward the high-G  zone (66) of the inlet region (68). This creates a strong flow of plasma that moves radially toward the low-G zone (64) of the inlet region (68) and elutes platelets into suspension with it. The systems and methods direct the radial flow of plasma and eluted platelets within the inlet region (68) to a port (72) in the inlet region (68) for transport out of the chamber (58).
