Calibration and correction system for satellite position location systems

Abstract: To provide accurate and quick position measurements in a practical mobile position location system, the GPS receiver is calibrated, a frequency error in the next time period is predicted using a first frequency locked to an externally transmitted signal, and a second frequency is generated by a GPS oscillator. To predict the error in the next time period, several measurements are made over time, error estimations are made, an error function is approximated responsive to the set of error estimations. This predicted error is then used to correct the GPS receiver in the next time period. In one implementation, a multiple function portable device is disclosed for providing cellular communication using a network of cellular stations that operate at predefined ideal cellular frequencies, and also for providing position location using GPS satellites that transmit GPS signals at a predefined GPS frequency.

Code generator and decoder for communications systems operating using hybrid codes to allow for multiple efficient users of the communications systems

Abstract: A method of encoding data for transmissions from a source to a destination over a communications channel is provided. The method operates on an ordered set of source symbols and may generate zero or more redundant symbols from the source symbols, wherein data is encoded in a first step according to a simple FEC code and in a second step, data is encoded according to a second FEC code, more complex than the first FEC code. The first FEC code and/or the second FEC code might comprise coding known in the art. These steps result in two groups of encoded data in such a way that a low-complexity receiver may make use of one of the groups of encoded data while higher complexity receivers may make use of both groups of encoded data.

Enabling a communication feasibility determination time to complete communication exchanges between an m2m server and one or more m2m devices

Abstract: A method, an apparatus, and a computer program product for machine-to-machine communication are provided. A device receives a request from a requestor. The request requests the device to transmit information to the requestor according to a primary time duration. The device determines at least one secondary time duration within the primary time duration for transmitting the information to the requestor and schedules a transmission time within the at least one secondary time duration to transmit the information to the requestor in response to the request. The scheduling is based on additional information known to the device. A requestor determines a time duration for communicating with at least one device, transmits a request to the at least one device to transmit information to the requestor according to the time duration, and receives in response to the request the information from the at least one device within the time duration.

Method and apparatus for determining relevant point of interest information based upon route of user

Abstract: Methods, apparatus, and systems for determining the relevance of points of interest for a user are described. An application server receives information about a user's location, and velocity, as well as other user preferences, and adjusts a search space and filters points of interest identifying those that are relevant to the user. The relevance of the points of interest are based on the user's route, location and velocity.
