Title: Method for channel adaptive detecting/equalizing
IPC: H04B7/005
Filed: 1991-08-19
Abstract: In a communications device, two coherent detection al-gorithms (102 and 103), one of which has a decision feedback equalizer (103), and a detector selection algorithm (104) are used to dynamically select a detector depending on whether delay spread distortion is present. First the correlation of the detector without the equalizer (102) is measured. If this corre-lation is greater than a predetermined threshold, the data from that detector (102) is used by the communications device. If the correlation is less than the threshold, the correlation of the detector with the equalizer (103) is measured. If this is less than the correlation of the detector without the equalizer (102), the data from the detector without the equalizer (102) is used, otherwise the data is taken from the equalizer (103).

Title: System for enhancing data transfer between application programs and communications programs in telecommunications systems
Inventor: STACY ROGER A
IPC: G06F13/00
Filed: 1991-08-30
Abstract: SYSTEM FOR ENHANCING DATA TRANSFER BETWEEN APPLICATION PROGRAMS AND COMMUNICATIONS PROGRAMS           IN TELECOMMUNICATIONS SYSTEMS          ABSTRACT      A method, and a computer program system for performing the method, enhances the transfer of data streams between application programs and communications programs in telecommunications systems.  The enhancer system is interposed between a host computer network com-munications program, such as VTAM, and the application program being used for accommodating data transfer re-quests from end users in the VTAM environment.  The enhancer system intercepts data RECEIVE requests from the application program to the communications program.  A corresponding receive-accepted data signal is relayed to the application program, thereby allowing that program to continue execution without awaiting a response to its RECEIVE request. The enhancer system interacts with the communications program to realize the transfer of requested data therefrom when it becomes available. The requested data is subsequently transferred to the application program by interrupting the normal operation thereof and causing the program to generate appropriate RECEIVE requests responsive to which the sequential transfer of requested data occurs.   h:\bmca\064\pa\foreign

Title: Adaptive deemphasis and reemphasis of high frequencies in a video signal utilizing a recorded control signal
Inventor: STROLLE CHRISTOPHER H
IPC: G11B20/02
Filed: 1991-10-25
Abstract: ABSTRACT OF THE DISCLOSURE      A video signal recording system is disclosed which includes a circuit for generating a control signal representative of the level of the high frequency portion of a full bandwidth luminance signal.  An adaptive deemphasis circuit reduces the level of the high frequency portion of the luminance signal in response to the control signal.  A folding circuit folds the high frequency portion of the deemphasized luminance signal into the low fre-quency portion.  The folded deemphasized luminance is combined with the control signal and recorded on the video tape.  A video signal playback system is disclosed which includes a circuit for separating the previously recorded control signal from the previously recorded folded deemphasized luminance signal.  An unfolding circuit unfolds the played back luminance signal to produce a wide bandwidth deemphasized luminance signal.  An adaptive reemphasis circuit boosts the level of the high frequen-cy portion of the unfolded luminance signal in response to the separated control signal.

Title: Gas analysis system for furnaces and the like
Inventor: POOR RALPH P
IPC: C21D1/76
Filed: 1992-02-05
Abstract: A system for use in sensing the oxygen content of an industrial furnace gas typically containing hydrocarbons or hydrogen is disclosed.  The system utilizes a conventional automotive EGR oxygen sensor probe positioned in an espe-cially configured housing employing downstream flow regulat-ing means in combination with an orificing plate in the housing to provide uniform distribution of the endothermic gas at a low temperature about the sensor to insure accurate sensor readings with minimal carbon deposition.  The elec-trical  contacts  at  the  oxygen  sensor's  inner  and  outer electrolyte surfaces are periodically switched to an elec-trical power supply to cause current to flow through and heat the electrolyte to elevated temperatures while air is flowed over the electrolyte's surfaces to achieve burn out of any carbon deposits and restore the life of the oxygen sensor probe.  In addition, a portion of the sensor is ther-mally shielded to maintain somewhat equal reference air and furnace gas temperatures to produce consistent and reliable output signals from the oxygen sensor probe.

Patent CA-2063528-A1 (CA)
Inventor: FUKUMOTO HIDESHI
IPC: H01F6/06
Filed: 1992-03-19
Abstract: There is disclosed a coil structure which is rapidly energized or excited, and reduces the generation of heat in a coil container by eddy current due to a dynamic disturbance such as vibration and a magnetic field fluctuation, thereby suppressing the generation of a quench.  The coil container is constituted by a low-resistivity material, and a high-resistivity portion is provided at at least one portion of the coil container in the direction of the periphery of the coil container. The high-resistivity portion is provided at a position where a vibration displacement is small or a magnetic field fluctuation is small.  When the coil structure is to be energized or excited, the eddy current produced in the direction of the periphery of the superconducting-coil container can be reduced at the high-resistivity portion, and when the dynamic disturbance develops, the generation of heat by the eddy current is suppressed by the low-resistivity material.

Abstract: ABSTRACT    This invention is directed to hand support and positioning device for surgical and post surgical purposes.  It comprises a base, trough support, arm trough and attached adjustable hand support.  The hand support is adjustable so that the forearm-wrist angle can be varied according to need, and also the metacarpophalangeal joint of the fingers can be placed in flexion or extension.  These required position aids treatment by reliably fixing the patient's hand in position, and thus relaxing the patient.  The hand support may be directly attached to the trough or to the trough support.  Advantageously, the hand support has two pivotally connected surfaces, so that the finger-hand angle can be varied according to need.  A goniometer arrangement is preferably included to allow accurate measurement of the angles.
