Patent number: 9331616Abstract: An integrated circuit is configured for controlling automobile door lock motors. The circuit includes half-bridge driver circuits, with each half-bridge driver circuit having an output node configured to be coupled to a door lock motor. A control circuit is configured to control driver operation of the half-bridge driver circuits. A current regulator circuit senses current sourced by or sunk by at least one of the half-bridge circuits. The control circuit responds to the current regulator circuit and the sensed current by controlling the driver operation to provide for a regulated current to be sourced by or sunk by said half-bridge circuit. The control circuit further controls the half-bridge driver circuits to enter a tri-state mode in order to support the making of BEMF measurements on the motor.Type: GrantFiled: October 25, 2013Date of Patent: May 3, 2016Assignee: STMICROELECTRONICS, INC.Inventor: David F.

Patent number: 9325631Abstract: A system and method for improved upstream data transmission. In an embodiment, a cable modem includes a transceiver configured for transmitting data upstream once permission is granted. In between times when permission to transmit is granted, however, the cable modem is configured to prepare as much data as possible for immediate upstream transmission once that very permission is granted. Thus, prior to permission being granted, the cable modem assembles (pre-processes) the data into transmit frames such that the data frames may be stored in a local memory coupled to the transceiver in a “ready-to-go” format. In this manner, the entire amount of time/bandwidth allocated to the cable modem in response to its request for upstream data transmission may be dedicated to actually transmitting data upstream as opposed to consuming time and bandwidth processing the data into data frames after upstream data transmission has been granted.Type: GrantFiled: September 12, 2013Date of Patent: April 26, 2016Assignees: STMICROELECTRONICS, INC., CISCO TECHNOLOGY, INC.Inventors: Charaf Hanna, Zhifang J.

Publication number: 20160104644Abstract: Dummy gates are removed from a pre-metal layer to produce a first opening (with a first length) and a second opening (with a second length longer than the first length). Work function metal for a metal gate electrode is provided in the first and second openings. Tungsten is deposited to fill the first opening and conformally line the second opening, thus leaving a third opening.
