Patent number: 11982905Abstract: A pixel array may be illuminated with backlight illumination from a backlight. The backlight may include a two-dimensional array of light-emitting diodes, with each light-emitting diode being placed in a respective cell. Different light-emitting diodes may have unique brightness magnitudes based on the content of the given display frame. Driver integrated circuits may control one or more associated light-emitting diodes to have a desired brightness level. The driver integrated circuits may be formed in an active area of the backlight. The driver integrated circuits may be arranged in groups that are daisy chained together. A digital signal (that includes information such as addressing information) may be propagated through the group of driver integrated circuits. To manage thermal performance of the backlight, the backlight may include a thermally conductive layer and/or a heat sink structure. To increase the efficiency of the backlight, the backlight may include one or more reflective layers.Type: GrantFiled: March 16, 2021Date of Patent: May 14, 2024Assignee: Apple Inc.Inventors: David W.

Patent number: 11978207Abstract: Oral care based imaging computer-implemented systems and methods for determining perceived attractiveness of a facial image portion of at least one person depicted in a digital image. The method has the following steps: a) obtaining a digital image comprising at least one oral feature of at least one person, wherein the digital image includes a facial image portion of the at least one person, the facial image portion having both positive and negative attributes as defined by pixel data of the digital image; b) analyzing the facial image portion; c) generating an Attractiveness Score indicative of a perceived attractiveness of the facial image portion based on the analyzed facial image portion in the obtained digital image; d) further generating an image description that identifies at least one area in said facial image portion based on the Attractiveness Score; and e) presenting the image description to a use.Type: GrantFiled: June 3, 2021Date of Patent: May 7, 2024Assignee: The Procter & Gamble CompanyInventors: Amirhossein Tavanei, Matthew Lloyd Barker, Faiz Feisal Sherman, Sherrie Lee Kinderdine, Scott Alan Hayes, David Anthony Hengehold, Yanyan He, Yumeng Ouyang, Jiahui Li, Nataliya Gurich, Ming Qi

Publication number: 20060098807Abstract: A testing and performance analysis methodology applies a series of test vector pairs to the input ports of an echo canceller under test. The test vector signal pair may represent a particular speech activity state transition, e.g., a Brady Model transition. A scoring compression function such as a sigmoid squashing function is used to evaluate quantized performance parameters. The sub-scores may be weighted and averaged to provide an overall performance score.Type: ApplicationFiled: November 5, 2004Publication date: May 11, 2006Inventors: William Page, Yan Wang, Timothy Wade, Mark Milot, Ibrahim Yavuz, David Qi

Publication number: 20060077987Abstract: High compression rate codecs in gateways servicing Voice-over-Internet Protocol (VoIP) and Voice Band Data (VBD) calls distort modem/fax Answer Back Tones (e.g., 2100 Hz), which may lead to signal distortion and call hang-ups. To prevent such occurrences, a method or corresponding apparatus forces originating and terminating gateways to stay in a low complexity non-voice compression codec (e.g., ITU G.711) after prenegotiating a high complexity, voice compression codec (e.g., G.729 or G.726) during a short beginning period of a voice call. The low complexity codec avoids distorted answer back tone leakage associated with previous solutions that use a notch filter to block the leakage, thereby significantly improving the success rate of a VBD call by completely eliminating modem answer back tone distortion caused by high complexity codecs that use voice compression and by completely eliminating use of the notch filter.Type: ApplicationFiled: October 8, 2004Publication date: April 13, 2006Applicant: Cisco Technology, Inc.Inventors: David Qi, Yan Wang, Timothy Wade

Publication number: 20060072484Abstract: A method, or corresponding apparatus, assumes a call is a Voice Band Data (VBD) call. The method disables a local echo canceller and transmits a tone that disables distal echo canceller(s) along a communications path across which the call is communicated. After disabling the echo cancellers, the echo cancellers are allowed to operate in a typical manner, such as according to ITU standards, after the call is established, including remaining disabled if the call is a Voice Band Data call and being automatically enabled if the call is or becomes a voice call. The method or apparatus is particularly useful in networks having Point of Service (POS) devices that have modems that do not send out a 2100 Hz tone to disable echo cancelling in the communications path. In one embodiment, the method or corresponding apparatus is deployed in a gateway.Type: ApplicationFiled: October 5, 2004Publication date: April 6, 2006Applicant: Cisco Technology, Inc.Inventors: David Qi, Yan Wang, Timothy Wade, William Page
