  • Patent number: 11875058
    Abstract: A control method for a multi-channel non-volatile memory is shown. When reading a read target on the non-volatile memory, the controller increases the read count of the monitored unit to which the read target belongs and, based on the read count, determines whether to move data of the monitored unit covering the read target to a safe space to deal with reading interference. The monitored unit is smaller than a cross-channel management unit in read-count group. The controller accesses a parallel accessing space of the non-volatile memory in parallel through all of the channels, and allocates the parallel accessing space based on the cross-channel management unit.

    Abstract: Creating a low-bandwidth channel in a high-bandwidth channel. By taking advantage of extra bandwidth in a high-bandwidth channel, a low-bandwidth channel is created by inserting extra packets. When an inter-packet gap of the proper duration is detected, the extra packet is inserted and any incoming packets on the high-bandwidth channel are stored in an elastic buffer. Observing inter-packet gaps, minimal latency is introduced in the high-bandwidth channel when there is no extra packet in the process of being sent, and the effects of sending a packet on the low-bandwidth channel are absorbed and distributed among other passing traffic.

  • Patent number: 7818635
    Abstract: In a digital broadcast receiver, when a bit error rate (BER) is larger than a threshold in a BER determining part, power is supplied to a first tuner and a second tuner for diversity reception. When the BER is smaller than the threshold, power supply to one of the first tuner and the second tuner is stopped for single reception. This structure allows power supply to one of the tuners to be stopped in excellent reception environments, thus reducing power consumption.

  • Patent number: 7693090
    Abstract: The present disclosure generally pertains to systems and methods for discovering PME bonding groups. In one exemplary embodiment, a plurality of communication links are terminated by physical medium entities (PMEs). In this regard, each link is terminated at one end via a network PME and at another end via a remote PME at a customer premises. Each of the PMEs has a transceiver that is allowed to train during a training phase that precedes a data phase. After training, discovery of PME bonding groups is performed via data communicated over data phase control channels, which are operational while links are operational in the data phase, transmitting data using the Ethernet in the First Mile (EFM) encapsulation. For example, the control channel data may be communicated over a link-level embedded operations channel (EOC). In another example, the control channel data may be communicated using 64/65 Byte (B) code words.

  • Patent number: 7627335
    Abstract: A mobile electronic device having a keyboard has a cover plate acting as a dial keypad. The keypad has a push-through, hinge-spring design that activates only one of two keyboard keys underlying a dial key and allows backlighting transmissivity. A translucent material can be used to allow the keyboard key backlighting to be coupled through to a top dial key. The keypad creates an aesthetically balanced dial keypad arrangement over a QWERTY keyboard. A preferable mechanical implementation allows backlighting and has an offset contact and spring design to activate one of the two underlying keys. This activation simplifies the software implementation for executing the dial number since the signal is coming from one address rather than having to make a determination of whether it is coming from one or two addresses. Moreover, the resulting dial key press has a standard single click feel.

  • Patent number: 7606167
    Abstract: A storage area network and method for defining a static Fibre Channel Fabric that does not require a Principal Switch. The storage area network comprises one or more hosts, one or more storage devices, and a static Fabric connecting the one or more hosts and storage devices. Within the static Fabric, the Switches have their Domain_ID and Fabric_Name statically set. The method comprises accessing the Fabric, selecting a Switch in the Fabric, and statically configuring the Domain_ID and Fabric_Name for the selected Switch. The above sequence is repeated for each Switch in the static Fabric. In one embodiment, after being statically configured, the Switch is isolated from any dynamically set Switches in the Fabric. The Switch detects which of its Ports are connected to dynamically set Switches, and then isolates them, while maintaining operational the Ports connected to statically configured Switches.

  • Patent number: 7518986
    Abstract: A multi-chassis network device sends state information to internal consumers within the multi-chassis device via a hierarchical distribution. As one example, a primary master routing engine within a control node of a multi-chassis router forwards state information to local routing engines within other chassis, which in turn distribute the state information to consumers on each chassis. Each local routing engine defers sending acknowledgement to the master routing engine until acknowledgements have been received from all consumers serviced by the local routing engine. Embodiments of the invention may reduce control plane data traffic and convergence times associated with distribution of state updates in the multi-chassis network device.

  • Patent number: 7486683
    Abstract: A method for selecting packets to be switched in a collapsed virtual output queuing array (cVOQ) switch core, using a request/acknowledge mechanism. According to the method, an efficient set of virtual output queues (at most one virtual output queue per ingress adapter) is selected, while keeping the algorithm simple enough to allow its implementation in fast state machines. For determining a set of virtual output queues that are each authorized to send a packet, the algorithm is based upon degrees of freedom characterizing states of ingress and egress adapters. For example, the degree of freedom, derived from the collapsed virtual output queuing array, could represent the number of egress ports to which an ingress port may send packet, or the number of ingress ports from which an egress port may receive packets, at a given time.
