Patent number: 9397384Abstract: A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. An operator may touch, or be sufficiently proximate to, an antenna module of the NFC device to operate and/or control the NFC device. The antenna module includes antenna components that are characterized by a corresponding characteristic impedance. The touch, or sufficient proximity, of the operator changes the corresponding characteristic impedance of antenna components. The NFC device may determine a location of the touch, or proximity, of the operator based upon this change. The NFC device may interpret the location of the touch, or proximity, of the operator as information from the operator to operate and/or control the NFC device.Type: GrantFiled: May 18, 2015Date of Patent: July 19, 2016Assignee: Broadcom CorporationInventors: David Grant Cox, Andrew Pienkowski

Publication number: 20160202932Abstract: A Ternary Content-Addressable Memory (TCAM) system is disclosed. In the system, writes to the memory are performed over several cycles. In order to ensure full visibility of all entries within the TCAM, a cache memory is provided. At the start of the TCAM write, the cache is written with the contents of the new entry. The cache entry is activated for the period of time that the corresponding entry in the TCAM is deactivated for rewriting. For each input value provided to the system, both the TCAM and the cache are checked for potential matches. The results of these checks are compared at output. In this manner, all entries within the TCAM can maintain full visibility even throughout a write period.Type: ApplicationFiled: November 24, 2015Publication date: July 14, 2016Applicant: Broadcom CorporationInventor: Sachin Prabhakarrao KADU

Patent number: 9379882Abstract: Systems and methods are provided to use of out-of-band (OOB) channels for the transport of network-synchronization signals and network control information. These OOB channels transport synchronization and control channels over low-frequency bands outside of the frequency bands used for the data channels. Locating expensive network-synchronization functions in the optical network unit (ONU) and sharing the derived synchronization signals among multiple downstream customer premises equipment (CPE) devices results in cost savings and provides a means for maintaining a continuous, end-to-end synchronization reference, even during periods when the data channels on the copper network segment are in an energy-efficiency mode (e.g., a low-power and/or sleep mode).Type: GrantFiled: May 2, 2014Date of Patent: June 28, 2016Assignee: Broadcom CorporationInventors: Lowell D.

Patent number: 9379825Abstract: A new protocol uses a trigger message to identify one or more symbols transmitted between a first and a second communication device. The first device generates and transmits a trigger message to the second device. This process may be initiated based on the first device receiving a measurement initiation message from another device (e.g., such as the second device or another device within the system). Then, the first device transmits a signal that includes those one or more symbols to the second device. Before or during transmission, the first device generates a first capture of those one or more symbols. After receipt of the transmission from the first device, the second device performs a second capture of those one or more symbols identified within the trigger message. Then, any device having the first and second captures can determine a characterization of the communication pathway between the first and second devices.Type: GrantFiled: September 30, 2014Date of Patent: June 28, 2016Assignee: Broadcom CorporationInventors: Bruce Joseph Currivan, Roger Wayne Fish, Lisa Voigt Denney, Niki Roberta Pantelias
