  • Patent number: 10365978
    Abstract: Techniques for synchronizing snapshot operations in a distributed consistency group of storage volumes. The disclosed techniques employ a schedule of discrete snapshot operations (e.g., pausing I/O requests from host computers, taking snapshots of storage volumes, un-pausing the I/O requests), which is provided to storage appliances storing the storage volumes within the distributed consistency group. By pre-scheduling such discrete snapshot operations to be performed by the storage appliances, an amount of real-time communications (e.g., issuing snapshot commands, receiving snapshot acknowledgements) required to complete the snapshot operations is reduced, allowing data storage systems to more easily satisfy I/O time-out requirements and avoid application unresponsiveness and/or crashes.

  • Patent number: 8653935
    Abstract: A low-power wireless network involves a plurality of RF-enabled fluorescent lamp starter units. In each of a plurality of intervals, a receiver of a starter unit operates in a receive mode during a beacon slot time, and for the majority of the rest of the interval operates in a low-power sleep mode. The starter unit wakes up and listens for a beacon each beacon slot time, regardless of whether a beacon is transmitted during that interval or not. A starter unit can be commanded to schedule a future action (for example, for a time between widely spaced synchronizing beacons) by making one of the beacons a scheduling beacon. The scheduling beacon includes a field that the starter unit uses to schedule the future action. If the scheduled action is to be canceled before the next widely spaced synchronizing beacon, then an action-canceling beacon is communicated in the next interval.

A UE timing relative to the general timing is ascertained. An initial resource element (RE) value is adjusted by a pre-compensating amount to obtain a pre-compensated RE value, in which the pre-compensating amount is based on the UE timing relative to the general timing. The pre-compensated resource element value is supplied as one of a plurality of values to be transmitted. An IFFT is performed on the plurality of values to be transmitted to obtain pre-compensated initial signal information. A cyclic prefix is appended to the pre-compensated initial signal information to form an OFDM symbol for transmission from the non-reference transceiver to the UE.

    Abstract: In a projector or an optical receiver, a master device produces pieces of definition information that determines timings of detection processes in the device including its own device and transmits the pieces of definition information to the slave device. The master device simultaneously transmits commands to require operations of internal timers to be synchronized with each other to the other slave devices in response to elapse of a time corresponding to a period in which a circulating period of the detection processes of the sensors proceeds by a predetermined cycle. Each of the slave devices corrects the timer in response to the command, and determines a timing at which a detection process should be performed with reference to a time point for correction on the basis of the definition information matched with its own device to execute the detection process.

  • Patent number: 8054160
    Abstract: Active multi-modal RFID tags, illuminator/tag/reader systems, circuit architecture and opera-tional algorithms for battery power conservation that extends tag battery life from a typical 6 months to >5 years. The inventive system is particularly useful in asset and person tracking/inventory systems where power conservation is critical. The tag is configured with a micro-processor operational instruction set algorithm, modifiable on the fly via RF or IR, to synchro-nize a periodic tag awaken/sense envelope that overlaps the illuminator trigger pulse cycle and put the tag into deep, power conservation sleep for N periods of illuminator cycles. When the tag sees an illuminator signal with a different ID, or no illuminator signal at all, it transmits that anomaly via RF to a reader. This means the object or person with which the tag is associated has been moved out of the original illuminator field of view, permitting near real time investigation and tracking.

  • Patent number: 7995620
    Abstract: A method for transferring data between a data transmission system and a processor of a participant in the data transmission system. All components of the data transmission system are synchronized to a common global time base. The operating system time base of the participant processor is synchronized to the global time base of the data transmission system at least prior to a data transfer, and, to this end, a synchronization clock pulse that is synchronous to the global time base of the data transmission system is provided for synchronizing the operating system time base. This synchronization clock pulse may be provided by a hardware and/or software arrangement. In a data transmission system for implementing the method, the synchronization clock pulse is provided by suitable arrangement(s) of the communications controller and applied to the host processor via a synchronization line.

  • Patent number: 7973643
    Abstract: RFID readers transmit data to query tags at one or more data rates. Before transmitting data, the RFID readers also transmit special preambles that inform of the data rate that will be used for transmitting the data. The preambles have a call aspect and a rate aspect. The rate aspect has a feature substantially determined from a rate selected for transmitting the data. The feature may encode the rate indirectly or explicitly. The call aspect may be implemented by call transitions that define a timing, whose duration is independent of the selected rate. The duration may be advantageously set according to an assumed state of the RFID tag bandwidth filter. Therefore an RFID tag may use the call aspect of the preamble to prepare itself for receiving data, and the rate aspect to determine its rate of transmission for setting its filter bandwidth accordingly.
