摘要： System and method for enabling push-to-talk (PTT) private calls in a wireless communications network are described. One embodiment includes selecting a called party private identification for a private call by a calling party on a mobile device; pressing a PTT button on the mobile device; transmitting a SIP SUBSCRIBE including the calling and called parties private identifications to request a speech token; redirecting the SIP SUBSCRIBE to the PTT Server for purposes of removing the calling party and the called party from a multicast group; receiving an acknowledge message that includes a speech token; transmitting calling party information from the PTT Server to the called party; communicating speech packets from the calling party to the called party in a half-duplex manner; releasing the PTT button on the mobile device; transmitting a SIP SUBSCRIBE to release the speech token; and notifying the calling and called parties that the group's speech token is available.

摘要： In a data acquisition system, digitizing circuitry (2A) is powered up by a control signal (ADC_CONVST), superimposing a glitch (42-1) on a first multiplexed and amplified signal value (VINF) received by the digitizing circuitry. Sampling and holding of the first multiplexed and amplified signal value occurs during a delay provided between the glitch and a beginning of a first A/D conversion of the first multiplexed and amplified signal value to allow settling of the glitch. After the first conversion begins, a second multiplexed and amplified signal value is generated. The digitizing circuitry performs the first A/D conversion during initial settling of the second multiplexed and amplified signal value and then is powered down while the second multiplexed and amplified signal value continues to settle.

摘要： Certain aspects of the present disclosure relate to techniques for denoising of physiological signals. A signal (e.g., physiological signal) comprising at least two signal channels can be decomposed (e.g., using independent component analysis (ICA)) into at least two independent components. Then, independent component (IC) denoising can be applied to estimate which of the at least two independent components belong to a signal space and which of the at least two independent components belong to a noise space using a statistical metric associated with the at least two signal channels. A de-noised version of the signal can be generated by preserving in the signal only one or more independent components of the at least two independent components belonging to the signal space.

摘要： A method and system for measuring latency is provided. A monitor node is used to measure latency in a computer network or in a computing device by time stamping signal messages sent from nodes in the computer network and/or tasks in a particular node or device. The time stamps are generated using a system clock of the monitor node to reduce any discrepancies in timing. In addition, the monitor node may compensate for latencies between the monitor node and each of the one or more nodes or devices across which latency is to be measured. Signal messages may include a data message ID and/or a node ID identifying the message that is being tracked and for which latency is being measured. Latency may further be measured across multiple tasks being performed in the same or different nodes or devices by transmitting signal messages for each of the multiple tasks.

摘要： Systems and methodologies are described that facilitate paging a peer in a peer-to-peer communication network. Paging messages may be communicated directly between a wireless terminal and its peer(s). Further, the wireless terminal may monitor for incoming paging messages during subinterval(s) of a paging interval as a function of an identifier of the wireless terminal. Moreover, the wireless terminal may transmit a paging message to a peer (e.g., detected and/or identified during peer discovery) during subinterval(s) of the paging interval as a function of an identifier of the peer.

摘要： Embodiments of the disclosure provide methods, apparatus, and articles allowing two nodes to communicate in a slot-based direct sequencing spreading communication system. Both a preamble sequence and a payload data spreading PN sequence are generated from the Time of Day and a given user code. Generated sequences are synchronized between two communicating nodes to allow slot-based DSSS communication to take place. Generated sequences also change dynamically from slot to slot to provide waveform security.
