Abstract: When wireless binding or pairing is required, two wireless devices change from a normal broad wireless operating range to a reduced wireless operating range. The wireless devices then conduct binding or pairing operations in the reduced wireless range. This prevents other wireless devices in the same area from detecting the same reduced range binding signaling and inadvertently binding with the wrong devices. After the reduced range binding operations are completed, the wireless devices automatically switch back to the broader normal wireless operating range and use the exchanged binding information for conducting normal wireless communications. The reduced range pairing scheme creates a simple and intuitive technique for pairing wireless devices without requiring the user to press buttons or select devices from a list.

Abstract: A method and apparatus for creating USB peripheral device report descriptors: A short, compressed, report descriptor is stored in a peripheral device. This short report descriptor is transmitted to a USB wireless bridge and combined with templates stored in the bridge to create a USP report descriptor. Power is saved because less time is required to transmit the short report descriptor than would be required to transmit a full USB report descriptor. Hardware is also saved in the peripheral device since less memory is required to store the short report descriptors as compared to storing a full USB report descriptor.

Abstract: Disclosed is an improved noise reducing apparatus using an anti-circuit, including a digital logic circuit and a digital anti-circuit corresponding to the digital logic circuit. The digital anti-circuit functions to cancel noise generated by the digital logic circuit. The anti-circuit includes logic to generate a similar number of switching edges as the logic circuit, where the anti-circuit edges are in the opposite direction as the logic circuit.

In some embodiments, the differently structured components can include a state machine coupled to a memory or look-up-table.

Separate direct memory access controllers may be used for each of the receiver and transmitter. Processing is distributed over two or more processors. One processor may be a lower power processor while another processor may be a higher power processor. At least one of the two or more processors may be programmable or reconfigurable. The transceiver is configured to provide internal loop back self testing at various points in the processing. Timing within the transceiver may be established almost entirely by a single clock domain.

Abstract: The present invention is a method and apparatus for providing a pseudo random sequence for a spread spectrum system that prevents interception and provides real estate and power consumption efficiency. A pseudo random sequence may be created in real-time by associating a pseudo random sequence of a channel location of the carrier frequency at an instant in time. For example, the entire band of the spread spectrum system may be scanned to detect a channel with a low received signal strength. The location of the channel, or the actual frequency of the channel, could be associated with a particular pseudo random sequence to create a hop set for frequency hopping. Additionally, the location of a characteristic of the spread spectrum system, such as a noise characteristic, could be utilized to determine a content of a pseudo random sequence.

Abstract: A method and apparatus for time and space domain shifting of broadcast signals is disclosed. A broadcast station in a first geographic location transmits in a first time frame a broadcast signal to a local receiver also located in the first geographic location. The local receiver encodes the broadcast signal into an encoded signal capable of being transmitted via a world wide network, and then transmits the encoded signal via the world wide network. The transmitted encoded signal is received by a media player located within a second geographic location outside the first geographic location and coupled to the world wide network, and the encoded signal is decoded by the media player such that information contained within the signal is capable of being reproduced.

Abstract: A system to generate a wakeup signal for a low power device: The system includes a capacitor, the capacitance of which changes when a user touches the device by placing a finger or hand near a certain location on the device. The capacitor is cyclically charged to a pre-established value and then discharged. The time required to charge and discharge the capacitor is a function of the capacitor size and thus, a function of whether or not the operator is touching the device. The number of charge-discharge cycles that occur in a certain period of time is counted. If the number is relatively small, it indicated that a user is touching the device and a wake signal is generated. If the number is relatively large, it means that the user is not touching the device and no wake signal is generated. Thus, in the embodiments shown, a wake signal is generated when the operator touches the device.
