Patent number: 9237109Abstract: A system and method suited for improved overall data transmission having a hardware-based transceiver configured for transmitting upstream data with suppressed data packets. In TCP sessions between devices, a server seeks an “acknowledgement” that the downstream data transmission has been received by a client. Some data packets sent upstream may contain only TCP acknowledgement data and therefore may be combined with other purely TCP acknowledgement data packets in order to reduce the impact of the TCP acknowledgement packets on the overall upstream data throughput. In addition, this results in increased TCP performance in the downstream transmission direction as well because the algorithm enables replacing earlier arriving ACK packets with later arriving ACK packets which allows the device to send all TCP ACK information known to the suppressor at the earliest possible time.Type: GrantFiled: September 12, 2013Date of Patent: January 12, 2016Assignees: STMICROELECTRONICS, INC., CISCO TECHNOLOGY, INC.Inventors: Gale L.

Patent number: 9237184Abstract: A wireless sensor network including a plurality of Smart Sensors coupled to a wide area network such as the Internet via a Wireless Sensor Coordinator. Each wireless sensor network comprises a plurality of Smart Sensors, each operable to measure one or more physical quantities. Each wireless sensor communicates the measured data to a Wireless Sensor Coordinator which then stores the collected data in memory. The Wireless Sensor Coordinator further includes a web server operable to post a web site on a network that is accessible by a common web browser. Upon receiving a request for sensed data via the web site, the Wireless Sensor Coordinator retrieves the appropriate measured and stored data and converts it into HTML format pages which are then posted on the web site for review by the requestor.Type: GrantFiled: November 12, 2013Date of Patent: January 12, 2016Assignee: STMicroelectronics, Inc.Inventors: Bo Kang, Jianjian Huo

Patent number: 9236474Abstract: Methods and structures for forming strained-channel FETs are described. A strain-inducing layer may be formed under stress in a silicon-on-insulator substrate below the insulator. Stress-relief cuts may be formed in the strain-inducing layer to relieve stress in the strain-inducing layer. The relief of stress can impart strain to an adjacent semiconductor layer. Strained-channel, fully-depleted SOI FETs and strained-channel finFETs may be formed from the adjacent semiconductor layer. The amount and type of strain may be controlled by etch depths and geometries of the stress-relief cuts and choice of materials for the strain-inducing layer.Type: GrantFiled: February 21, 2014Date of Patent: January 12, 2016Assignee: STMICROELECTRONICS, INC.Inventor: Pierre Morin

Patent number: 9236909Abstract: An embodiment is an integrated System on Chip (SoC) including a communication interface configured to implement a communication protocol including functional blocks that are energized or de-energized individually so that a minimum power consumption is used to receive and detect a signal, and a receiver identification (ID) detection function configured to determine whether the signal is intended for the device in which the SoC resides. The SoC further includes a power management function configured to control which functions in the SoC and/or device in which the SoC resides are energized or de-energized depending on the results of the receiver ID detection function, and a power source capable of energizing a minimum number of the functional blocks required to receive and detect a signal, wherein the power source can be used in a low power state and switched over to a main power supply when the SoC is energized.Type: GrantFiled: December 3, 2014Date of Patent: January 12, 2016Assignee: STMicroelectronics, Inc.Inventor: Oleg Logvinov

Patent number: 9237525Abstract: This invention relates to switching power saving modes and rescheduling communication frames for various periods of a beacon interval (BI) defined under WGA Draft Specification 0.8 for the personal basic service set (PBSS) and infrastructure BSS to achieve further power savings and other advantages. Stations can be awake during a contention-based period (CBP) if it is in active state and can schedule frames during a service period (SP) to allow the assigned receiver to transmit to the assigned initiator. Stations in a group can schedule a group address frame to be sent during the CBP and group SP of a specific periodic BI. Stations in peer-to-peer connection may directly notify its peer stations of its power saving mode and wakeup schedule. Stations of an infrastructure basic service set (BSS) can also use the same power saving mechanism as stations of a PBSS noting a difference where each BI will be an access point's (AP's) awake BI.Type: GrantFiled: March 6, 2014Date of Patent: January 12, 2016Assignee: STMICROELECTRONICS, INC.Inventors: Liwen Chu, George A.

Patent number: 9232469Abstract: An additional cyclic redundancy check (CRC) is inserted in IEEE 802.11 beacon or data frames prior to the end of the frame, at a location following information sufficient for the receiving station to determine whether the frame is from an overlapping basic service set or intended for a different station and to extract other necessary or useful information such as a time of the next full beacon. Upon detecting the CRC, the receiving STA can terminate reception of the frame early to conserve power, and then enter a low power operational mode to further conserve power.Type: GrantFiled: September 12, 2013Date of Patent: January 5, 2016Assignee: STMICROELECTRONICS, INC.Inventors: Liwen Chu, George A.

Patent number: 9232472Abstract: Multiple virtual MAC addresses may be added to WGA devices that may have different traffic streams to another device that requires different services, thus creating distinct MAC and device level implications. Beamforming training can be done at the device level for all virtual MAC addresses. Wakeup, doze, and ATIM power save can be done at the device level depending on the frames received. Authentication, deauthentication, association, and deassociation can be done variously at both levels. Further MSDUs can be aggregated for the multiple MAC addresses.Type: GrantFiled: December 22, 2011Date of Patent: January 5, 2016Assignee: STMICROELECTRONICS, INC.Inventors: Liwen Chu, George A.

Patent number: 9220457Abstract: A device for correlating trend data with respect to a patient's weight and lower extremity displacement can identify conditions indicative of congestive heart failure. An imaging mechanism is operable to measure lower extremity displacement over a period of time.

Patent number: 9214429Abstract: Ultra-low-k dielectric materials used as inter-layer dielectrics in high-performance integrated circuits are prone to be structurally unstable. The Young's modulus of such materials is decreased, resulting in porosity, poor film strength, cracking, and voids. An alternative dual damascene interconnect structure incorporates deep air gaps into a high modulus dielectric material to maintain structural stability while reducing capacitance between adjacent nanowires. Incorporation of a deep air gap having k=1.0 compensates for the use of a higher modulus film having a dielectric constant greater than the typical ultra-low-k (ULK) dielectric value of about 2.2. The higher modulus film containing the deep air gap is used as an insulator and a means of reducing fringe capacitance between adjacent metal lines. The dielectric layer between two adjacent metal lines thus forms a ULK/high-modulus dielectric bi-layer.Type: GrantFiled: December 5, 2013Date of Patent: December 15, 2015Assignees: STMicroelectronics, Inc., International Business Machines CorporationInventors: John H.
