Abstract: In a wireless communication system in which a base station communicates with plural mobile stations using a control channel and plural voice (or data) channels, the present invention uses the control channel as a voice channel whenever the other voice channels are in use and a request is received from a mobile station for another voice channel. The base station's use of the control channel varies as the control channel switches from a control channel to a voice channel and back to a control channel again.

Abstract: In a wireless communication system in which plural base stations communicate with plural mobile stations using a control slot and plural voice (or data) slots, the present invention dynamically allocates which of a predetermined set of frequencies are used by a given base station at a given time. The base stations monitor the predetermined set of frequencies to determine which frequencies are being used within which slots within the range of radio reception of the base station. Currently unused frequency/slot combinations are assigned by a base station to service the next request for a voice slot.

Abstract: A single bias block for a single or multiple low voltage RF circuits including one or more amplifiers and one or more single or double balanced mixers with compensation for temperature and integrated circuit process parameters. The power supply may be a lower voltage without sacrificing the dynamic range of the amplifier and/or mixer by applying full power supply voltage to the load with the bias applied to the base circuit through an operational amplifier and/or buffer circuit. For the mixer, a lower noise figure may also be realized by moving the gain control impedance from the emitter to the collector circuit. The circuits may be discrete components or part of an integrated circuit. Methods are disclosed for reducing the power supply voltage without affecting the dynamic range of an amplifier, for temperature and process parameter compensation, and for controlling the gain of a mixer without affecting input or output impedance.

Abstract: In a semiconductor island structure with passive side isolation, a method and structure for reducing corner breakdown where a device conductor crosses the edge of the island. The decrease in the field strength at the island edge between the conductor and the adjacent conducting region may be achieved by increasing the depth of the insulator beneath the conductor where it crosses the island edge without the necessity for increasing the thickness of the layer of insulation applied directly to the surface of the island by the use of a second or higher level interconnect, e.g., the conventional deposition of one or more additional layers of insulation over the device terminal to increase the spacing between the conductor and the surface of the island. In this way the process by which the device is constructed may remain unchanged.

Abstract: A device and method for testing a telephone circuit in which a caller takes advantage of available caller identification information to complete a ringback test without resort to potentially costly and overused toll trunks. The ringback test device is accessed by a caller (subscriber or craftsperson) who may not be aware of the telephone number from which he is calling when the caller completes a call to a telephone number assigned to the device. As the caller is accessing the test device, the test device detects the caller identification available between the first and second rings to identify the caller's telephone number, and answers the call after the second ring. The test device presents the telephone number to the caller, and the test device may thereafter be used to complete a ringback test to the identified telephone number. The caller ID information may also be display-formatted at the test device and provided to a caller's visual display.

Abstract: A trench emitter controlled thyristor 30 having a collector layer 32, a drift layer 34, a body layer 36, and a floating layer 38. Each of the layers 32, 34, 36, and 38 contacts the adjacent layer(s). The floating layer 38 does not cover the entirety of the adjacent layer (the body layer 36) but at one of the lateral ends of the thyristor 30, an emitter 40 is formed. A gate area (or electrode) 43 is formed to span laterally across the thyristor 30. Additionally, trenches are formed into the lateral edges 44 of the body layer 36 and a portion of the drift layer 34. Within the trenches 44 are formed additional gate area 42 which runs for substantially the length of the thyristor 30. The gate 42 is kept electrically isolated from the remainder of the thyristor by an insulating region 46 directly over the body layer 36.

Abstract: Use of ISA Adapter Card (ISAAC) to insure timing of application of power and logic to ISA, SCSA and MVIP Cards when those cards are plugged into standard ISA connectors of the ISAAC and the ISAAC is subsequently plugged into an active ISA, SCSA, and/or MVIP bus(es) such that any server connected to the back plane does not have to be shut down to protect ISA, SCSA and MVIP cards when inserted and removed from the back plane.

Abstract: A frequency dependent resistor in which the length of the current path across the resistor varies as a function of the frequency of the electrical signals being passed therethrough. The resistor uses the principal known as skin effect to direct relatively higher frequency signals through a longer path through the resistor than is experienced by signals having a relatively low frequency.

Abstract: The present invention proposes light-weight and easy-to-handled deodorizing material that has a large contact area with bad smell-causing gas as well as better deodorizing performance and also that enjoys a smooth circulation of that gas with a lower permeation resistance. A single-faced corrugated fiberboard made of a cellulose-based substance is allowed to contain ferrous sulfate, which is subsequently oxidized into basic ferric sulfate.

Abstract: A telephone switch system is connected digitally to an external computer system operating database software and having access to a digitally stored database of information used by the switch. The switch performs data transactions on the database in the manner of a client. The database engine allows live queries, which automatically update querying clients as pertinent data changes. The database engine also allows query concentration, which caches query results and supplies the cached results to querying clients making identical queries within a prescribed period of time. The database engine further allows batch inserts, which allow a user to add a plurality of records with a single command.

Abstract: Antimicrobial protection may be provided to protective gloves by mixing an antimicrobial agent in a glove material film so that the antimicrobial agent migrates to the exposed surfaces of the gloves when the agent on the glove surface has been depleted.

An auxiliary power switch is provided in parallel to the main power switch which is operable during the reverse recovery of the antiparallel diode, after which the main power switch carries the bulk of the switch current.

Abstract: Storing and transporting meat products after marinating and before packaging causes a loss of marinade from the meat product. This loss of marinade is reduced by surrounding the marinated meat product in excess marinade during storage and by containing the marinated meat product in an enclosed conduit, surrounded by excess marinade, and pressurizing the marinade during transportation of the marinated meat product.

Abstract: A system for communicating with plural remote transmitters in which the transmitters send messages without a common synchronization source or polling by a controlling receiver. In one embodiment, the system uses the time position of frequency chirp signals to encode the identity and/or other information sent from the receiver. The system may use relatively low cost transmitters because the transmitters do not need to have a message or clocking signal receiving capability and the internal clocking signal source within the transmitter may be a relatively inexpensive device or circuit.

Abstract: A low distortion amplifier and method of reducing distortion in an amplifier at high output power in which energy dissipated while the amplifier is operating at low output power, is reduced. A bias circuit provides a quiescent bias current to the input stage of the amplifier for operating the amplifier without substantial distortion at low input signal levels and low output power. A sense transistor senses a current less than and proportional to an output current from the amplifier, and feeds back the sensed current to the input stage to augment the quiescent bias current when output power increases. When the output power decreases, the sensed current is removed in order to maintain the low power output bias currents.

Abstract: A thick film, electroluminescent lamp and method of construction in which a single non-hygroscopic binder is used for all layers (with the optional exception of the rear electrode), thereby reducing delamination as a result of temperature changes and the susceptibility to moisture. The use of a common binder for both phosphor and adjacent dielectric layers reduces lamp failure due to localized heating, thus increasing light output for a given voltage and excitation frequency, and increasing the ability of the lamp to withstand overvoltage conditions without failure. Layers may be provided on both sides of a common rear electrode to provide a lamp with two independently operable lamp surfaces. A front electrode may be exposed on a side of the lamp with the rear electrode by cutting the layers down to the front electrode after the layers have been joined.

Abstract: A sine/cosine generator with coarse and fine angles having compressed sine and cosine read only memories (ROMS) by use of symmetry of coarse angles about .pi./4 and, optionally, symmetry of fine angles about 0. The output of the ROMs directly feed multiplexers for utilization of the compressed storage. Addressing of complementary coarse angles is with one's complementing of the address and of complementary fine angles is with two's commplementing of the address. Fine sines and cosines are stored in recoded version for direct use in multipliers for computations using the sum of angles formulas.
