Title: Received signal decision apparatus for digital modulated signal receiver
Inventor: TSUMURA SOICHI
IPC: H04L27/22
Filed: 1995-07-13
Abstract: A received signal strength detector detects a received signal strength corresponding to an envelope of a received signal and outputs a received strength signal corresponding to the strength level.  A DC component extracting filter extracts a DC component from the received strength signal and outputs an ex-tracted DC component signal corresponding to the level of the DC component.  A modulation rate component extracting filter extracts a line spectrum component corresponding to a modulation rate from the received strength signal and outputs an extracted modulation rate component signal corresponding to the level of the modulation rate component.  A decision compares the ex-tracted DC component signal and the extracted modula-tion rate component signal with respective threshold levels set therefor and decides, when the levels of the two signals are higher than the respective threshold levels, that the received signal is an optimum signal.          The decision may otherwise be based on comparison of a ratio between the two extracted signals with a thresh-old level set therefor.  An attenuator may be provided on the input side of the received signal strength detector such that it may be controlled, when the decision decides that the received signal is not opti-mum, so as to lower the gain of the receiver to prevent otherwise possible saturation of the received signal output of the receiver.

Title: Aqueous dispersions of synthetic materials, method for their manufacture and use thereof
Inventor: STADELMANN-SIDLER URSULA
IPC: C08G18/00
Filed: 1995-11-02
Abstract: Synthetic dispersions in aqueous media are described in which the synthetic material is a polyure-thane or a polyurethane urea containing per 100 g of the polymeric material, 5-30 milli-equivalents of anionic or cationic groups linked directly to the polymeric struc-ture. The core of the synthetic material is composed of an aliphatic polyetherdiol which is assuring the flexibi-lity of the polymeric material and also the polyisocya-nate component is selected in a way that it does not introduce a considerable content of rigid segments.            The dispersions can be used for the genera-tion of sealing junctions, e.g. of a variety of objects, whereby the sealing junction displays a high elongation, a low modulus of elasticity and a good elastic recovery. Thus, a certain displacement in space of the objects linked through said sealing juncture is possible, with a transmission of the forces from one object to the other being as low as possible, without formation of cracks in the sealant and without the formation of cracks in the connected objects itselves.

Title: Methods for selectively stimulating proliferation of t cells
Inventor: JUNE CARL H
IPC: A61K35/14
Filed: 1994-06-03
Abstract: Methods for inducing a population of T cells to proliferate by activating the population of T cells and stimulating an accessory molecule on the surface of the T cells with a ligand which binds the accessory molecule are described. T cell proliferation occurs in the absence of exogenous growth factors or accessory cells. T cell activation is accomplished by stimulating the T cell receptor (TCR)/CD3 complex or the CD2 surface protein. To induce proliferation of an activated population T cells, an accessory molecule on the surface of the T cells, such as CD28, is stimulated with a ligand which binds the accessory molecule. The T cell population expanded by the method of the invention can be genetically transduced and used for immunotherapy or can be used in methods of diagnosis.

Filed: 1994-08-19
Abstract: A device for prevention of involuntary urination in a female comprises an elastic body (21) designed for arrangement in the vagina for compressive action on and support of the neck of the bladder. The body (21) is made of a compressible material and comprises at least two projecting legs (23) joined in a flexible base (22) and is dimensioned in such a way that in the non-deformed state of the body the longest distance between the free ends of at least two legs exceeds the distance between the anterior wall and the posterior wall of the vagina. After the insertion of the body into the vagina in an elastically deformed state with the legs tint in a direction towards each other, an active pressure is thus exerted on the bladder neck. On their mutually facing sides, the legs are designed in such a way that in said elastically deformed insertion state they come into mutual contact for the provision of an increased elastic force of restitution. An applicator for insertion of the device comprises an elongated member having a proximal end and a substantially rod-shaped distal end portion for abutment with a bevel or a recess (24) formed in the angle between the legs of the device.

Patent CA-2171693-A1 (CA)
Inventor: NICHOLS ANGELO H
IPC: F02D43/04
Filed: 1996-03-12
Abstract: The present invention provides a system for testing an engine designed to be run under the control of an engine control module.  The system modifies the operation of the engine while maintaining the engine control module active so as to allow control of the engine to be transferred between the engine management system and the engine control module.  The present invention allows an operator to alter the operation of the engine by varying the signals to the engine's injectors and ignition systems.  While the engine is operating under user defined injector signals, a simulated exhaust gas signal is provided to the engine control module.  This simulated exhaust gas signal allows the engine to be tested under operating conditions where the exhaust gas generated would cause correction by the engine control module making the test condition sought unsustainable.  The system can be programmed to periodically return all functions to the engine control module allowing the establishment of new operating parameters for the engine. In a preferred embodiment, the engine management system can also take control of the engine's electronic ignition system allowing the user to alter spark timing and ignition dwell time.  In addition to providing integrated injector and ignition control, the engine management system of the present invention allows the user to take engine control from and return engine control to the engine control module without knowing the details of the algorithms used to run the engine control module.

Abstract: Mobile stations correct their frequencies using a signal received from the moving relay station including correction of any Doppler shift caused by the satellite's movement. The mobile station includes a receiver for receiving a paging channel signal broadcast by the moving relay station and demodulators and decoders for decoding the information in the paging channel signal. Using the decoded information, the mobile station can determine an estimate of its position within the communication system. The mobile station can also determine a frequency error and a Doppler shift using the decoded information and the position estimate. A frequency controlling signal is determined using the determined frequency error and the Doppler shift. A controlled reference oscillator then uses the frequency correcting signal as a control input signal. Finally, the mobile station contains a transmitter for transmitting a signal using the voltage controlled oscillator as a reference.

IPC: G10L19/00
Filed: 1996-05-21
Abstract: A protocol for labeling various types of data contained in a music chip. The protocol includes a hierarchical arrangement of headers for storing information about selections on the chip and the method in which they were coded in the memory of the chip. A global header located at the very start of memory will specify information needed to successfully decode the content of the music chip. This will include, for example, the necessary bit rate, as well as information pertaining to a specific PAC (Perceptual Audio Coding) algorithm employed in recording audio on the chip. In addition to the global header, each chip will have a section of memory allocated to a table of contents. The table of contents will include information on play times, song titles, music category and artist. Individual track selections will be listed as part of the table of contents by individual headers. The individual header contains a music category to which a track belongs, for example, classical, jazz, country, rock, etc., the artist, and information for addressing each track selection. Information from the headers is self-registered or automatically downloaded when a chip is loaded into a player/juke box device. The concept of self-registering general information included within the headers allows a user to select by type of music, artist, etc. for music selections made over a period of time.
