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.

Multi-channel digital wireless audio system

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.

Multithread embedded processor with input/output capability

A wireless system for video game control comprised of a base transceiver engaged with an electronic game device where said base transceiver communicates wirelessly with one or more wireless controllers concurrently and which implements a variety of techniques to achieve significant advantages in the areas of latency, reliability, power consumption, and cross platform compatibility.

Wireless game control system

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.

A portable electronic apparatus comprises a housing for facilitating battery exchange therein. The housing has an opening for containing the battery. The opening has first and second apertures for permitting the battery to be pushed directly into contact with a retainer. Access to the battery is unobstructed to expedite battery exchange and to permit movement of the battery in different directions through the housing opening. Multiple retaining arms can have arcuate surfaces for holding the battery. The housing can have multiple retaining arms having complementary battery holding surfaces and can have two housing sections attached to the multiple retaining arms. Each of the two housing sections can be attached to retaining arms each having an arcuate surface for contacting the battery, and the retaining arms can be oriented in an interleaved configuration.

Quick change battery retainer

A portable, battery operated electronic device for facilitating battery exchange. The electronic device housing has an opening for containing the battery. The opening has first and second apertures for permitting the battery to be pushed directly into contact with a retainer. Access to the battery is unobstructed to expedite battery exchange and to permit movement of the battery in different directions through the housing opening. The method of the invention permits quick exchange of batteries so that continuous operation of the electronic device is not encumbered. By sliding the battery against electrical contacts within the opening, the contacts are automatically cleaned during battery replacement. Visual contact with the battery permits continuous display of battery charge strips attached to the battery exterior case.

Quick change battery system

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. The controller can be capable of identifying parameters regarding the signal such as the signal strength and is capable of polling information over one or more discrete time periods. Information regarding the signal can be communicated with a display such as a light.
