Abstract: A method for transmitting a route request in an ad-hoc network having master nodes and slave nodes includes transmitting the route request to the master nodes of the network via a unicast transmission and transmitting a reply identifying the route. Each node of the network which receives the request performs a route request algorithm. The algorithm may be implemented in the network layer of the device protocol stack or in the link layer of the device protocol stack.
Abstract: A method and corresponding apparatus for accurately determining the offset of the carrier frequency of a received signal from a nominal frequency (the offset due to for example Doppler shifting), such as is done in a ranging receiver when acquiring or tracking a signal transmitted by a beacon (such as a satellite) of a positioning system. The method amplifies a conventional correlation by performing a special noncoherent integration of the real and imaginary components of the output of a conventional (coherent) correlation calculation, resulting in a complex phasor having a phase that bears information about the offset of the carrier frequency from the nominal carrier frequency.
Abstract: A method and system for synchronizing the PN phase of a pseudo-noise (PN) coded signal with a phase of a master PN decade-code is provided. The method includes the steps of associating the master PN decade-code initialization t0 with a first time zone reference date and time and determining an elapsed time t1. The next steps equate the elapsed time t1 to a corresponding phase of the master PN code and synchronize the phase of the PN coded signal with the corresponding phase of the master PN decade-code.

Abstract: A system for storing and releasing information including a portable device and a receiver. The portable device includes a secure memory, a memory buffer, an access control system for controlling output of the information from the secure memory only upon a user entering an authentication, and a transmitter. The receiver is separate from the portable device for receiving the information transmitted from the transmitter. The information can be stored in the memory buffer and transmitted from the memory buffer by the transmitter to the receiver without the user entering the authentication. The information can be stored in the secure memory and transmitted from the transmitter to the receiver only upon the user entering the authentication such that the system allows alternatively releasing the information from the portable device with or without using the authentication.
Abstract: Method and system for processing charge messages in a telecommunication system comprising a registering point for distinguishing received charge messages from each other, a first telephone exchange connected to a calling subscriber and a second telephone exchange connected to a called subscriber, said telephone exchange using charge calculation based on charge messages of the originating and terminating side, a charge message being sent during call set-up from the originating side to the registering point. A charge message received from the terminating side is checked; the charge data or the originating side and terminating side are combined if they bear similarities; the charge message is modified to from a replacing charge message that contains the combined charge data; and the replacing charge message is sent to the registering point.

Abstract: The present invention provides a method and apparatus for a communications system that prioritizes packets that are transmitted over a digital communication channel utilizing at least one error-correcting transmission path associated with a Quality of Service (QoS) objective. The QoS objective is used to select the appropriate transmission path (that may include forward error coding, scrambling, and interleaving) that satisfies the relevant metrics of the desired level of service quality such as packet latency, variation of the packet latency, information throughput, and packet error rate (PER). The communications system selects a transmission path that is associated with QoS objectives best matched to the QoS objectives as required by the originating application.
