Abstract: METHOD FOR TRANSMITTING A HIGH-RESOLUTION IMAGE    OVER A NARROW-BAND COMMUNICATION CHANNEL                  Abstract of the Disclosure Information content of a high resolution image is to be sent over a narrow band communication channel (104) from transmitter (100) to a remote receiver (102). At the receiver, the information content is used to create an image on a display.  The invention makes the information content available quickly to the viewer.  To that purpose, the spatial frequency spectrum of the high resolution image is analyzed at the transmitter into a first, low-pass, remnant subspectrum band and into one or more additional subspectrum bands.  The subspectrum of the first band has a nominal high-frequency cutoff below that of the subspectra of the other bands.  Starking with the first, remnant band, the subspectra and are transmitted in sequence over the channel.  Each band, when received at the receiver, is used to create at the display the image with increasingly higher definition.

Granted: 1992-03-03
Abstract: ABSTRACT OF THE DISCLOSURE A fluidic bridge for determining the partial pressure of a gas has a positive pressure inlet for a reference gas and a sample gas and an ambient pressure outlet.  The reference gas and the sample gas pass through a capillary passage and an orifice passage, and the pressure differential between the outlet of the reference capillary passage and the outlet of the sample capillary passage is a function of the density of the gas.  A pressure ratio regulator is used to equalize the pressure of the reference gas and the sample gas applied to the inlets of the capillary passages.  The length of the capillary passages and the flow character stics of the orifice passages are adjustable to allow the bridge to be properly calibrated after being assembled.

Title: Method of determining and using an acceleration correction in an integrated acceleration based electronic speed control system for vehicles
Inventor: MCCOMBIE JAY C
IPC: B60K31/10
Filed: 1987-09-25
Granted: 1992-09-01
Abstract: ABSTRACT An error correction pulse is selected by integrating (or summing) the differences between the desired acceleration and the actual vehicle acceleration. The integral is compared to a trigger window. The throttle position is controlled based on the value of the integral as compared to the window. This is keyed in providing smooth control. The integration action serves to filter transient acceleration errors and to dampen throttle response to prevent throttle correction at a faster rate than the vehicle can respond thereby reducing over and under shoot of the throttle.

Title: Process of preparing higher order cuprate complexes
Inventor: CAMPBELL ARTHUR L
IPC: C07F1/08
Filed: 1988-06-07
Granted: 1992-12-15
Abstract: ABSTRACT OF THE DISCLOSURE This invention encompasses a process for preparing higher order cuprate complexes which contain a carbanion for the formation of carbon to carbon bonds in reactions such as 1,4-conjugate addition. The complex is formed by reacting a first cuprate complex with a stannane such that the carbanion to be used to form carbon to carbon bonds is transferred from the stannane to the first cuprate complex to form a different higher order cuprate complex. This process permits the in situ preparation of a higher order cuprate complex having the carbanion desired to be used in a synthetic reaction. Higher order cuprate complexes prepared by this process are particularly useful for the efficient preparation of pharmacologically active prostaglandins.

Abstract: SUBSTRATE MOUNTING DEVICE                       ABSTRACT       A substrate mounting device for installing an electrical substrate to a carrier substrate. The substrate mounting device includes a plurality of guide rails mounted on the perimeter edge of the electrical substrate.

Abstract: WHL/LHF     IMPROVED PRESSURE AND CONTACT SENSOR SYSTEM FOR MEASURING DENTAL OCCLUSION                 ABSTRACT     A contact sensor for detecting points on a grid where the sensor is being contacted on opposing sides by teeth surfaces or other contacting points. The sensor is especially useful for measuring dental occlusion   The contact sensor includes two sets of parallel electrodes which are each formed on a thin, flexible supporting sheet.  The electrodes are separated by a thin, pressure-sensitive resistive coating such as molydenum disulphide.  Two such electrode structures are oriented at approximately right angles to create a gride where the intersecting electrodes cross separated by the resistive coatings.  Several arrangements of resistive coating over electrodes are disclosed.  In the absence of an external force, the material betwee  the electrodes sets provides a high resistance between intersecting electrodes.  The resistance between electrode intersections changes as pressure on opposite sides of the intersection changes.  The sensor output is dynamic in that the resistance will vary as external pressure is repeately applied and removed.  The sensor may be made extremely thin and can provide high resolution capable of distinguishing between contact points separated by 0.050 inches or less.     WHL/LHF     A new circuit is provided which measures the resistance between each electrode intersection and provides an output representative of the opposing forces at the intersection.  The circuit limits the maximum possible current which can flow in the sensor and provides increase resolution in measuring pressure between contacting surfaces.
