Abstract: A plug-in control  box to TV or radio (2-pole, 3-position rotary switch, non-shorting) is capable of providing sound from TV or radio speakers, earphones alone, or speakers and earphones together.  In the speaker position, the sound level is adjusted for general surroundings.  In the earphone position, the TV/radio speaker sound is omitted.  If necessary, the earphone level can be further adjusted to suit the earphone listener.          In speaker and earphone position, the TV/radio sound can be adjusted if necessary, and the earphone sound separately.          These settings are for normal hearing.     The big feature of this invention is provision for the hearing impaired.     An amplifier, built into the control box, provides the mixture of TV/radio sound and ambient sound, through a plug-in microphone.          Both sound levels can be adjusted separately, to suit the hearing impaired (i.e. ambient sound, phone, doorbell, conversations, etc.) When using plug-in earphones to TV/radio, the speakers are cut off.  There is no external sound for those who wish to participate.          The hearing impaired are completely cut off from the outside world.  The purpose of this invention is to give the hearing impaired opportunity of enjoying TV/radio sound and ambient sound without disrupting other persons about.

Inventor: BELL ALAN E
IPC: G06T7/20
Filed: 1990-02-26
Abstract: A method and apparatus which provides for the real time comparison of raster data. The raster data is stored in memory such that raster data corresponding to a specific X-Y coordinate location is consistently written to the same memory location. During the process of storing the data in memory, the data currently stored in the memory is read and compared to the data to be written into the same location in memory. If the data is not the same, the discrepancy and location of the discrepancy is noted in a separate area of memory to be used for subsequent analysis and the the data to be written to that location is immediately written into the memory. The method and apparatus of the present invention is particularly applicable to the video graphics environment wherein the current bit of raster image contained in the frame buffer is compared to the updated raster image and the data changes are noted on a pixel by pixel basis. Utilizing the information gathered on the changed pixels, the video display need only update the changed data, thereby minimizing the amount of data to be transferred and increasing the speed of the system. In a preferred embodiment, the method and apparatus of the present invention is employed to provide an interface between a video adapter such as a video graphics array (VGA) and video display system incompatible with the video adapter such as a windowing system whereby the video output generated by the video adapter is translated and input to the video display system for generation of the display in real time.

Title: Control system and logic system for independent control of vehicle brakes
Inventor: COUTANT ALAN R
IPC: B60T13/12
Filed: 1990-04-30
Abstract: Abstract of the Invention Control System and Logic System for Independent Control of Vehicle Brakes Vehicle propulsion systems many times have a transmission with a directional control mechanism, right and left drive units, and a differential steer mechanism.  In these vehicles, there is no way of independently stopping one of the drive units in order to provide a pivot turn for better control of the vehicle when maneuvering in tight areas and on slopes. In order to ensure that the operator has selective, independent control of applying one or the other of the right or left brakes for steering, a control and a logic system is provided in a propulsion system to automatically apply the right or left brake on the respective drive unit with respect to operator input conditions.  In this arrangement, if the operator selects a clockwise steer of the vehicle, it will steer in the clockwise direction regardless of whether the vehicle is moving in the forward direction or the reverse direction.  Likewise, the same is true if the operator selects a counterclockwise steer direction of the vehicle.  This is accomplished by the control and logic systems sensing the travel direction of the vehicle, the steer direction of the vehicle, and automatically applying the proper brake based on the input conditions.  The control and logic systems set forth herein provides a selective independent control of the respective right and left brakes to provide more precise control of the vehicle when operating in tight areas and on slopes.

Title: Preparation and use of gene banks of synthetic human antibodies ("synthetic human-antibody libraries")
Inventor: LITTLE MELVYN
IPC: C12N15/13
Filed: 1991-01-31
Abstract: The invention relates to the preparation and use of gene banks of synthetic human antibodies (huAb) or parts of antibodies which contain the antigen-binding domain.      Starting from a huAb framework in a suitable vector, the hypervariable regions of the antibody cDNA are formed by almost "randomly" combined oligonucleotides. Relatively conserved amino acids in the hypervariable regions have here been taken account of in the choice of appropriate nucleotides during the oligonucleotide synthesis and the ratio of the nucleotides used is likewise chosen such that a nonsense codon is to be expected at most in every 89th position. Expression of this synthetic huAb cDNA in microbial expression systems, e.g. in E, coli in the vector pFMT which is described below, thus makes a synthetic huAb library with a comprehensive repertoire for screening using selected antigens available in vitro.
