  • Patent number: 9723541
    Abstract: Techniques for priority access to a priority access channel are described. In at least some embodiments, a portion of the radio spectrum is divided into general access (GA) channels and priority access (PA) channels. Levels of access to the different channels are controlled based upon priority levels of devices attempting to access the channels. For instance, embodiments employ a channel database that tracks available GA channels and PA channels, and notifies various devices of the available channels. The channel database may also track keys for PA channels that enable authentication of devices for priority access to PA channels. In at least some embodiments, tracking available GA channels and PA channels enables underutilized radio channels to be identified for various uses, such as for wireless broadband communication.

  • Patent number: 9629109
    Abstract: Disclosed are various embodiments for optimizing network event timers for a node. The node obtains data for transmission by the node via a network. The node uses time intervals of a clock as a basis for determining actions associated with the network. A transmission duration is calculated that corresponds to the time for transmitting the data via the network based on a data rate of the network and a size of the data. The node calculates a transmission delay based on the transmission duration. The transmission delay is less than a clock interval and controls when transmission of the data is completed by the node. After the expiration of the transmission delay, the node transmits the data via the network. The node initiates an event timer when the transmission is completed, where the event timer measures time based upon counting the time intervals elapsed since the event timer began.

  • Patent number: 9622265
    Abstract: Embodiments are provided for implementing a CSMA-CA half window scheme in 802.11 networks or other suitable wireless networks that could benefit from such scheme. The half window scheme improves a back-off time calculation by adding a probability prediction factor. The back-off time is part of a delay time in accessing a wireless transmission medium by a station (STA). The probability prediction factor is used to adjust a contention widow (CW) used to calculate the back-off time, based on the STA's medium access probability. The STA splits the CW into two at least half windows and then chooses one of the windows according to the window's information gain for the probability prediction. The selected window is used to select a random number for the back-off time. The improved back-off time calculation reduces contention between STAs in accessing the medium.

    Abstract: Examples are disclosed for techniques for allowing a wireless device to wake up a low power device while remaining compatible with other devices and wireless protocols. A first station determines that a low power device needs to wake up all or a portion of its circuitry in order to send and/or receive data from the first station. The first station sends a legacy preamble according to a standard wireless communication method such as according to IEEE 802.11 or Bluetooth addressed to the low power device. Legacy stations will recognize that a device is accessing the medium and will abstain from transmitting data during the transaction(s) between the first station and the low power device. The first station then sends a wake up payload according to a low power wireless communication method such as ASK or FSK to the low power device. The low power device recognizes the wake up payload and wakes up its main radio such as an IEEE 802.11 or Bluetooth radio.

    Abstract: The present disclosure provides a secure one-step IEEE 1588 clock using either a symmetric or asymmetric protection scheme. Clocks of mission-critical or highly-available devices in industrial automation systems connected to a communication network are synchronized by sending, by a master clock, a synchronization message, e.g., a single message of the one-step-clock type according to IEEE 1588, including a time stamp, and by receiving and evaluating, by a slave clock, the synchronization message. A synchronization component or module of the master clock prepares, or composes, prior to a projected send time, a synchronization message including a time stamp of the projected send time, and secures the synchronization message in advance of the projected send time. Securing the synchronization message occurs by suitable cryptographic means allowing for authentication of the time stamp at a receiving slave clock. At the projected send time, the secured synchronization message is transmitted.

  • Patent number: 9258249
    Abstract: Techniques for resource access throttling are described. In implementations, access to a network resource can be controlled based on a variety of factors, such as a type of user requesting access to the network resource. For example, consider a scenario where an online content store is preparing to launch. To prevent resources associated with the online content store from being overwhelmed by the number of requests for access when the store is launched, techniques can be implemented to throttle the number of requests that are granted. For instance, requests for access can be throttled based on different user types.

  • Patent number: 9203505
    Abstract: An approach for transmission of data packets, based on virtual frame timing, over a communications channel is provided. A remote terminal receives a first stream of data packets at periodic time intervals. The terminal receives an allocation of time slots within a sequence of TDMA transmission frames, for transmission of the data packets over the channel. The timing structure of the allocated time slots is based on a virtual frame size relative to the interval timing of the first data packet stream, and independent of the frame size/timing of the TDMA transmission frames. The remote terminal may receive a second stream of data packets at periodic time intervals that differ from the time intervals of the first stream. In a multi-stream scenario, the virtual frame size for the time slot allocation is based on the greatest common denominator of the interval timings of the first and second data streams.

  • Patent number: 9149188
    Abstract: A patient monitor system synchronizes patient data acquired by a plurality of sensor modules. Patient data from the sensor modules are synchronized by transmitting, from a patient monitor host, a start message that each newly connected sensor module uses to determine when to begin transmitting patient data to the patient monitor host. At a predetermined count interval, the patient monitor host also broadcasts an incrementing sequence count value to each of the connected sensor modules. The sensor modules use the sequence count values and the start message to determine when the patient monitor host expects each sensor module to transmit data packets. Each data packet sent by the sensor modules includes a sequence count value that the patient monitor host uses to align the various waveforms for display.

  • Patent number: 9125114
    Abstract: A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement.

  • Patent number: 9092143
    Abstract: An improved technique for measuring I/O latency in an I/O driver of a host computing system includes obtaining the tick size of a high resolution clock of the host and setting the boundaries of I/O latency buckets at different calculated numbers of high resolution clock ticks. The I/O latency buckets are used for binning latency measurements made by the I/O driver. The boundaries of the I/O latency buckets are expressed as numbers of high resolution clock ticks and correspond to a sequence of predetermined time values. At runtime, the I/O driver measures the latency of I/O requests using timestamps obtained from the high resolution clock. The latency measurements are expressed as numbers of elapsed ticks. The I/O driver then assigns measured latency values to data buckets by comparing ticks to ticks, without the need for unit conversion or resource-intensive arithmetic.
