Patent number: 9918293Abstract: A monitoring device may monitor its proximity to a monitored station. The monitored station may transmit a proximity indicator to the monitoring device. For example, the proximity indicator may include the received signal strength of a signal sent by the monitored station. Wireless interface control circuitry at the monitoring device may monitor the status of the proximity indicator for changes. If one or more criteria set by an application processor are met by a detected change, the wireless interface control circuitry may send a status update to the application processor. In the criteria are not met, generation of the status update may be forgone. The application processor need not monitor the proximity indicator status and may remain in a reduced power consumption mode for longer periods.Type: GrantFiled: May 28, 2014Date of Patent: March 13, 2018Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 9792622Abstract: A power transmitting device includes a processor circuit. The processor circuit receives messages, such as advertising messages and/or scan response messages, from power receiving devices. The messages include device specific data that pertains to the corresponding power receiving devices that transmitted the messages. The device specific data includes, for example, data pertaining to the hardware, firmware, charging state, and/or device state of the corresponding power receiving device. The processor circuit selects one of the power receiving devices based in part on the device specific data contained in the messages. The processor circuit initiates a wireless power transfer connection to the selected one of the power receiving devices.Type: GrantFiled: September 5, 2014Date of Patent: October 17, 2017Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.

Patent number: 9516690Abstract: A wireless communication device includes a wireless charging circuit configurable to receive a wireless power signal from a power transmitting unit and to charge the wireless communication device under control of a processing device and in conjunction with a charging session with the power transmitting unit. A wireless interface device operates under control of the processing device to establish a wireless connection with the power transmitting unit via a connection establishment procedure, wherein the wireless connection is separate from the wireless power signal. Control data is exchanged with the power transmitting unit via the wireless connection, wherein the control data is used by the processing device to implement the charging session with the wireless charging circuit. A response is generated to a disruption event of the wireless communication device that includes implementing a restoration procedure for restoring the wireless connection, without implementing the connection establishment procedure.Type: GrantFiled: October 26, 2015Date of Patent: December 6, 2016Assignee: BROADCOM CORPORATIONInventors: Chikan Kwan, Xin Tian, Erik John Rivard, Xianbo Chen, Lih-Feng Tsaur

Patent number: 9277415Abstract: A device implements multiple protocols that share overlapping resources. In some cases, a first operation, such as a scan, may have a resource conflict with a second operation associated with a different protocol. In some cases, determining grant normal priority level requests associated with the first operation over those at the normal priority level associated with the second operation may lead to operator-noticeable degradation in device performance. A protocol controller may request a selected portion of the first operation at a low priority level. Requesting the selected portion at the low priority level may allow the second operation to selectively override the portion of the first operation. The selective overriding of the first operation may allow for execution of the first and second operations without operator-noticeable performance degradation.Type: GrantFiled: July 21, 2014Date of Patent: March 1, 2016Assignee: Broadcom CorporationInventors: Erik John Rivard, Lih-Feng Tsaur, Shawn Shiliang Ding, Hsiao-Kai Wang, Shanshan Jiang, Daochun Liu

Patent number: 7167502Abstract: A communication system transmits orthogonally encoded data at a symbol rate which is selected from a plurality of symbol rates. The data is encoded in a plurality of packets, each packet having a plurality of symbols having signal points in a field. The signal points of consecutively transmitted symbols are correlated unless the rate is changed, and the data is encoded such that only particular orthogonal descendants of a selected maximum rate code are used. The encoded data is transmitted to a receiver, and orthogonally decoded. A change in the rate of data transmission is recognized when the signal points of consecutively transmitted symbols are not correlated.Type: GrantFiled: November 22, 2000Date of Patent: January 23, 2007Assignee: Skyworks Solutions, Inc.Inventor: Lih-Feng Tsaur
