Publication number: 20170031007Abstract: An electronic device includes a ranging light source and a reflected light detector. A logic circuit causes the ranging light source to emit ranging light at a target. Reflected light from the target is detected using the reflected light detector, with the reflected light being a portion of the ranging light that reflects from the target back toward the reflected light detector. An intensity of the reflected light is determined using the reflected light detector. A distance to the target is determined based upon time elapsed between activating the ranging light source and detecting the reflected ranging light. Reflectance of the target is calculated, based upon the intensity of the reflected light and the distance to the target.Type: ApplicationFiled: July 27, 2015Publication date: February 2, 2017Applicants: STMicroelectronics (Research & Development) Limited, STMicroelectronics, Inc.Inventors: Darin K.

Patent number: 9560372Abstract: An appropriate motion vector to assign to a pixel in a digital video frame is performed by a comparison of motion vectors of particular surrounding pixels. Direction of at least one of color transition or color brightness transition in the digital video frame is detected to detect direction of object boundaries in the digital video frame. The particular surrounding pixels are selected and grouped (filtered) according to the detected object boundary direction at each pixel. A comparison of the motion vectors of the surrounding pixels then provides information on which group of pixels to assign a current pixel being processed based in part on how close the motion vectors of the surrounding groups match a group pixels to which the pixel being processed belongs.Type: GrantFiled: December 27, 2010Date of Patent: January 31, 2017Assignee: STMICROELECTRONICS, INC.Inventor: Anatoliy Vasilevich Tsyrganovich

Patent number: 9548222Abstract: A brush-cleaning apparatus is disclosed for use in cleaning a semiconductor wafer after polishing. Embodiments of the brush-cleaning apparatus implemented with a multi-branch chemical dispensing unit are applied beneficially to clean semiconductor wafers, post-polish, using a hybrid cleaning method. An exemplary hybrid cleaning method employs a two-chemical sequence in which first and second chemical treatment modules are separate from one another, and are followed by a pH-neutralizing-rinse that occurs in a treatment module separate from the first and second chemical treatment modules. Implementation of such hybrid methods is facilitated by the multi-branch chemical dispensing unit, which provides separate chemical lines to different chemical treatment modules, and dispenses chemical to at least four different areas of each wafer during single-wafer processing in an upright orientation.Type: GrantFiled: October 7, 2013Date of Patent: January 17, 2017Assignee: STMicroelectronics, Inc.Inventor: John H.

Patent number: 9548361Abstract: A self-aligned SiGe FinFET device features a relaxed channel region having a high germanium concentration. Instead of first introducing germanium into the channel and then attempting to relax the resulting strained film, a relaxed channel is formed initially to accept the germanium. In this way, a presence of germanium can be established without straining or damaging the lattice. Gate structures are patterned relative to intrinsic silicon fins, to ensure that the gates are properly aligned, prior to introducing germanium into the fin lattice structure. After aligning the gate structures, the silicon fins are segmented to elastically relax the silicon lattice. Then, germanium is introduced into the relaxed silicon lattice, to produce a SiGe channel that is substantially stress-free and also defect-free. Using the method described, concentration of germanium achieved in a structurally stable film can be increased to a level greater than 85%.Type: GrantFiled: June 30, 2015Date of Patent: January 17, 2017Assignee: STMICROELECTRONICS, INC.Inventors: Nicolas Loubet, Pierre Morin

Patent number: 9544847Abstract: A IEEE 802.11 Wireless Local Area Network (WLAN) system of an access point (AP) and one or more stations (STAs) reduces power consumption and increases battery life of power efficient low power STAs by decreasing the amount of time that a power efficient low power STA remains in an awake state. After indicating power efficient low power operation during association with an AP supporting such operation, the power efficient low power STA may enter the doze state from the time that the power efficient low power STA sends a PS-Poll until the power efficient low power STA receives the buffered DATA frame from the AP. While implementing the power efficient PS-Poll method, the AP can send the buffered DATA frame to the STA SIFS after the AP sends an ACK to the received PS-Poll from the STA.Type: GrantFiled: July 18, 2016Date of Patent: January 10, 2017Assignee: STMICROELECTRONICS, INC.Inventors: Liwen Chu, George A.
