    Abstract: A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range "serial" type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

    Abstract: A mobile device (10) comprises a receiver and a coherent integrator (104), wherein the receiver is configured to receive a first signal from a satellite, the first signal including a navigation message. The coherent integrator is configured to coherently integrate first signal samples for a particular coherent integration interval. When the coherent integration interval straddles a data boundary of the navigation message, the coherent integration is divided into a section before the data boundary of the navigation message and a section after the data boundary of the navigation message

    Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment of the invention comprises a method for performing position location comprising the steps of receiving signal samples, generating a coarse acquisition sequence, rotating the coarse acquisition sequence yielding a rotated coarse acquisition sequence, and applying the rotated coarse acquisition sequence to the signal samples at a set of time offsets yielding correlated output data.

    Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment comprises a method for performing position location in a wireless communication system using a set of signals transmitted from a set of satellites including the steps of receiving signal samples, rotating an acquisition code by a first rotation amount yielding a rotated acquisition code, despreading said signal samples using rotated acquisition code yielding despread data, accumulating said despread data over a first duration yielding partially accumulated data, rotating said partially accumulated data by a second rotation amount yielding rotated data and accumulating said rotated data.

    Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. In one embodiment the invention comprises a method in a subscriber unit (10) for performing position location in a CDMA wireless communications system having a base station (12), the method comprising: receiving a position location request containing aiding information from the base station (12) over a first receive frequency; in response to the position location request, tuning a receiver (52, 54, 102, 104) of the subscriber unit (10) away from the first receive frequency to a position location frequency in order to receive position location information; and receiving information over the position location frequency and using the received information to perform a position location procedure, the method being characterized by: including data transition boundary information in the aiding information.
