  • Patent number: 9213660
    Abstract: A data processing apparatus is provided with a master device and a slave device which communicate via communication circuitry. The slave device is associated with a predetermined number of permission tokens that is equal to a maximum number of currently pending messages that can be accepted for processing from the communication circuitry by that slave device. The slave device transmits these permission tokens to the master device. The master device takes exclusive temporary possession of the permission tokens that it receives such that the permission tokens are then no longer available to any other master device. A master device initiates a message to a slave device when the master device has exclusive temporary possession of a permission token for that slave device. When the master device has initiated its message, then it relinquishes the exclusive temporary possession of the permission token such that it is then available for other devices.

  • Patent number: 8885558
    Abstract: A method enables a radio receiver to distinguish sensor probes supplying data to the receiver over a long period of time. The method includes each probe generating a random number sent to the receiver to identify the probe. Each probe and the receiver also uses a pseudo-random process to identify a time of transmission for each probe. The pseudo-random process helps keep the transmission times for the probes separate in the presence of oscillator drift. If a transmission collision occurs, the receiver ignores all probes in the collision and waits until the pseudo-random process separates the probe transmissions.

    Abstract: A method of managing a ring-based overlay network that is configured to allow routing of messages across an underlying IP network to destinations not specified by an IP address. The method comprises firstly sending a probe message from an initiating node of the overlay network around the ring, with each peer node forwarding the probe message to a successor or predecessor node. Upon detection of a forwarding failure at a node of the ring, a Probe error message is sent from that node to the initiating node. The initiating node represents the final destination for the Probe message.

  • Patent number: 7890057
    Abstract: A roadside apparatus is connected to a roadside network and an in-vehicle apparatus which carries out wireless data transfer with the roadside apparatus, and it is equipped with a specifying unit for specifying an in-vehicle apparatus by associating an IP address which was assigned with respect to each in-vehicle apparatus, and an in-vehicle apparatus identifier other than an IP address. By this configuration, between the roadside apparatus and the in-vehicle apparatus, enabled is data communication which utilized an IP series communication protocol for specifying an in-vehicle apparatus by use of an IP address which was assigned with respect to each in-vehicle apparatus, and a non-IP series communication protocol for specifying an in-vehicle apparatus by use of LID.

  • Patent number: 7860063
    Abstract: A wireless access terminal is configured to enter into a freeze state where the wireless access terminal temporarily stops decoding and receiving data for a first access network, when the wireless access terminal's modem tunes away from the first access network to monitor signals from a second access network. When the modem tunes back, the wireless access terminal continues processing signals from the first access network without re-initializing with the first access network. When the terminal enters the freeze state, state variables for the terminal's various protocols, including layer 1, layer 2, and modem controller protocols can be stored so that the protocols can continue processing when the modem tunes back, without the need to reinitialize.

  • Patent number: 7808917
    Abstract: The invention relates to a system and a method for transmitting telegrams. The system has at least one first communication means provided for sending telegrams and at least one second communication means provided for receiving telegrams, with a telegram having a check value that can be determined from a useful data component of the telegram, with the first communication means having a first telegram counter provided for assigning a count value to a telegram in accordance with a send sequence. To improve error detection during the transmission of telegrams it is proposed that the count value for determining the check value be a constituent of the useful data component is, that information signaling a change in the count value be a constituent of the useful data component when the telegram is transmitted, that the second communication means have a second telegram counter, and that means be provided for synchronizing the first and second telegram counter.

  • Patent number: 7738484
    Abstract: Multiple initialization techniques for system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible system/socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small server, large server, etc., as well as the component types such as IA32/IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated. For example, the POC values could be from the following: Platform Input Clock to Core Clock Ratio, Enable/disable LT, Configurable Restart, Burn In Initialization Mode, Disable Hyper Threading, System BSP Socket Indication, and Platform Topology Index.

  • Patent number: 7664072
    Abstract: A virtual stream (VS) in a basic service set (BSS) in a wireless local area network (WLAN) that exists solely within the medium access control (MAC) sublayer of the WLAN. The VS includes a unidirectional path in the wireless network between a station sourcing a quality of service (QoS) session and at least one station receiving the QoS session in the same BSS. The VS is defined by a VS identifier (VSID) that is unique within and local to the BSS, an address of the sourcing station, and an address of the at least one receiving station. The VS can be a virtual down-stream (VDS), a virtual upstream (VUS) or a virtual side-stream (VSS). The VS can be a unitcast or a multicast VS.

  • Patent number: 7586976
    Abstract: An initial ranging detection for an orthogonal frequency division multiple access (OFDMA) wireless communication system entails removing data sub-carriers from samples of an OFDMA signal in order to suppress inter-carrier interference (ICI) between the data sub-carriers and initial ranging sub-carriers, coherently summing the resulting samples to boost signal energy, and applying a sliding window FFT to the coherently summed samples for correlating each result of the sliding window FFT with each one of a set of predetermined codes. The suppression of ICI is done by removing the cyclic prefix, performing an FFT to transform to the frequency domain whereupon the initial ranging sub-carriers are zeroed. An IFFT is then performed to return to the time domain. The cyclic prefix is then added and the new samples are subtracted from the originally received samples. The resulting samples are free of ICI and can then be coherently summed to boost signal energy.

  • Patent number: 7400574
    Abstract: A method and apparatus for managing a loop network, the loop network (200) including at least one loop (206, 208), a plurality of devices (210) connected to the at least one loop (206, 208) via ports (211, 212), wherein at least two of the devices are initiators (207, 209). The method includes each initiator (207, 209) sending a frame to all other initiators (207, 209) in the loop network (200) identifying any ports (211, 212) which should not be used. Each initiator (207, 209) merges the information from all other initiators (207, 209) with its own information identifying any ports (211, 212) which should not be used resulting in all the initiators (207, 209) generating a single list of ports (211, 212) to be used which is consistent across all the initiators (207, 209). Each initiator (207, 209) applies an algorithm (300) to determine a common set of ports (211, 212) to be used by all the initiators (207, 209) and to balance port accesses across the loop network (200).
