Abstract: In a system providing for delivery of audio signals from one or more source audio systems to two or more audio output sink systems, the sink systems establish duplex communication links (or bonds) to a bonding subsystem which is in duplex communication with the source audio systems. Data signals may be sent from sink systems, via the bonding subsystem, to request delivery of audio signals from selected audio source channels. The sink systems may request specific treatments of or modifications to audio signals to be sent to individual sinks in the sink systems. The bonding subsystem relays treatment requests from the sink system to a matrix manager which initiates and controls the processing of source audio channels as required to comply with requests from the sink system. The matrix manager then delivers the treated or modified audio output channels to the bonding subsystem for delivery to the requesting sink systems.

Abstract: A system for wireless transmission between a device such as a game controller and a base transceiver linked with a host device. Multiple controllers can be linked with the base transceiver through radio frequency transmission, and audio signals can be selectively transmitted therebetween. Audio commands can be introduced with manual controls at the controller for transmission to the base transceiver. Audio signals can be generated, mixed or otherwise processed by the combination of the host device and base transceiver for selective transmission to one or more controllers. The combination of manual switches, audio commands, and radio frequency transmission provides unique combinations of interaction between a person and the host device.

Abstract: In a multi-channel digital wireless audio system with at least one transmit node and at least one receive node, each node can both receive and transmit digital audio signals. Signals sent from a receive node to a transmit node may acknowledge satisfactory signal receipt, or may requesting retransmission of data packets received in a corrupted state. Original and retransmitted signals may be sent in compressed form to enable use of narrow-band digital radios. The system preferably incorporates a dual control channel to enable transmission of meta data. Each system node preferably incorporates a hardware-multithreaded processor adapted to implement various functions such as baseband functions, RF protocol functions, error correction functions, and audio processing functions, with each independent thread being adapted to implement a different functional block.

Abstract: In a system providing for delivery of audio signals from one or more source audio systems to two or more audio output sink systems, the sink systems establish duplex communication links (or bonds) to a bonding subsystem, which in turn is in duplex communication with the source audio systems. Data signals may be sent from sink systems, via the bonding subsystem, to request delivery of audio signals from selected audio source channels. In preferred embodiments, the sink systems may also request specific treatments of or modifications to audio signals to be sent to individual sinks in the sink systems. The bonding subsystem receives such treatment requests from the sink system and relays them to a matrix manager which initiates and controls the processing of source audio channels as required to comply with requests from the sink system. The matrix manager then delivers the treated or modified audio output channels to the bonding subsystem for delivery to the requesting sink systems.

Abstract: An embedded processor system having a single-chip embedded microprocessor with analog and digital electrical interfaces to external systems. A novel processor core uses pipelined execution of multiple independent or dependent concurrent threads, together with supervisory control for monitoring and controlling the processor thread state and access to other components. The pipeline enables simultaneous execution of multiple threads by selectively avoiding memory or peripheral access conflicts through the types of pipeline stages chosen and the use of dual and tri-port memory techniques. The single processor core executes one or multiple instruction streams on multiple data streams in various combinations under the control of single or multiple threads.

Abstract: An omni-directional, planar folded dipole antenna and related quadrature phase shifter implemented on printed circuit boards (PCBs) having differing properties that are perpendicularly engaged. The planar antenna segment is implemented on a single-sided inexpensive PCB and a quadrature phase shifter and system electronics are implemented on more expensive multi-layer PCBs. The invention reduces cost and improves system reliability because coaxial or like connectors of varying material and installation quality are not required between a planar antenna and a quadrature phase shifter. Planar antenna transmits radio frequency signals in an omni-directional pattern and is capable of receiving signals from remote dipole antennas positioned in arbitrary physical orientations. The quadrature phase shifter provides both phase shifting functions and also converts an unbalanced radio frequency transceiver output signal into a balanced input signal to the planar antenna.

Abstract: An improved game controller. D-pad keys are positioned above a printed circuit board-with plungers guided by housing apertures. The D-pad key is top-loaded into contact with the housing to simplify manufacture and operating reliability. The D-pad key can be depressed downwardly until it contacts a pivot supported by a pivot post. The combination of elements permits significant design flexibility in the orientation and shape and operation of a D-pad key. Front mounted triggers replace front mounted buttons attached to a separate vertical printed circuit board. The triggers function with the main printed circuit board, thereby reducing cost and enhancing product reliability.

Abstract: A portable game controller for operating an electronic game device. The controller communicates between a person and the game device with a radio frequency sender and receiver. Signal transmission is communicated over the same channel with time domain multiplexing, and can be sent over one or more channels to expand the number of controllers operable in a system. Signal transmission can be delivered in short intervals to conserve battery power. Multiple persons can deliver signals through multiple senders or through a common radio frequency sender, and signals can be transmitted from the radio frequency receiver to the radio frequency sender.

Abstract: An apparatus for applying electrical current to biological tissue such as skin, bone or muscle. A portable housing can be powered with a battery or attached cord leading to an alternating current or direct current power supply. An extendible arm permits a person to apply the treatment without assistance, and the housing can be operated with a single hand. An amplifier generates a high voltage direct current, and a controller generates a high quality square waveform output. Such waveform comprises an output to an electrode assembly in electrical contact with the biological tissue. The electrode assembly comprises at least one negative electrode and at least one positive electrode which generate an electric current through the biological tissue between the positive and negative electrodes. The electrode assembly is movable relative to the biological tissue so that the current path is continually changing.

Abstract: A game controller for communication between a user and an electronic game device transmitting signals to a receiver. The game controller identifies weakness in signal strength or operation and permits adjustment to a more effective operating frequency. The game controller comprises a portable housing, game controller keys attached to the housing for permitting the user to generate signals, a radio frequency sender engaged with the game controller keys for transmitting the signals to the receiver; and a controller attached to sender for determining a selected parameter regarding the signals and for communicating the parameter to the user. The radio frequency sender is capable of transmitting signals over multiple frequencies and preferable operates with the Remote Band frequency range. At least one of the keys can be operable by the user to change the signal frequency or the controller can automatically change the signal frequency to a more effective frequency.
