Patent number: 9607424Abstract: According to various embodiments of the invention, a system and method are provided for enabling interaction with, manipulation of, and control of depth-assigned content in depth-enhanced pictures. Depth-assigned content can be assigned to a specified depth value. When a depth-enhanced picture is refocused at a focus depth substantially different from the specified assigned depth value, the depth-assigned content may be omitted, grayed out, blurred, or otherwise visually distinguished. In this manner, content associated with an in-focus image element can be visually distinguished from content associated with an out-of-focus image element. For example, in at least one embodiment, depth-assigned content is visible only when an image element associated with the content is in focus (or nearly in focus). According to various embodiments of the invention, many different types of interactions are facilitated among depth-assigned content, depth-enhanced pictures, and other content.Type: GrantFiled: June 26, 2012Date of Patent: March 28, 2017Assignee: Lytro, Inc.Inventors: Yi-Ren Ng, Eric Cheng, Chia-Kai Liang, Kayvon Fatahalian, David John Evans, Kira Wampler, Kristen Berman, Kurt Barton Akeley

Patent number: 8661390Abstract: A method is directed to automatic extraction of block binders before block placement and application of block binders in block placement of an integrated circuit. Having block binders reduces the effective block count the block placement has to handle, and enables obtaining better placement result in shorter run time. The method includes an algorithm of processing the nodes of a hierarchical net-list to identify candidate nodes or create new candidate nodes to contain identified nodes. The method includes an algorithm of extracting a block binder out of blocks under each candidate node. The method includes an algorithm of automatic packing and generation of various configurations for a block binder to provide flexibility in block placement. The method also includes adapting any block placement algorithm to select to the best fit configuration of any block binder during the placement process.Type: GrantFiled: February 13, 2012Date of Patent: February 25, 2014Inventor: Chihliang (Eric) Cheng

Patent number: 8328389Abstract: An LED display with a reduced thickness is described. In one embodiment, the LED display includes a second support plate between a front support plate and a back support plate. The second support plate enables the front support plate to be thinner than if the second support plate was not included. The second support plate increases the distance between an LED chip and a light exit surface thereby allowing the front support plate thickness to be reduced by about the thickness of the second support plate. In one embodiment, the second support plate allows the thickness of an LED display to be thinner. The second support plate adds structural integrity to a back support plate. Therefore, the back support plate can be thinner, and thickness of the LED display can be reduced.Type: GrantFiled: February 13, 2012Date of Patent: December 11, 2012Assignee: American Opto Plus Led CorporationInventor: Eric Cheng Yuan Wu

Publication number: 20120262067Abstract: A battery operated device such as a road stud comprises a micro-controller, a battery, and a light source. The micro-controller is configured to operate the battery to provide a train of power pulses to the light source, and each power pulse has a characteristic pulse period and a characteristic duty cycle comprising an on-cycle and an off-cycle. The micro-controller is turned on during the on-cycle and turned into a power saving or sleep mode during the off cycle. Setting the micro-controller into the power saving or sleep mode during the off cycle of the power pulse means substantial battery power saved to extend the operation time per charging of the battery.Type: ApplicationFiled: January 5, 2011Publication date: October 18, 2012Applicant: ECOTECH ENVIRONMENTAL TECHNOLOGY LTD.Inventors: Siu Chung Tam, Ka Wai Eric Cheng, Yanjie Bao, Daohong Wang, Wai Pang Yau

Patent number: 8217618Abstract: The present invention relates to an energy-saving system for three-phase induction motors and is based on the principle of variable voltage control at constant speed. It is composed of a microprocessor, exampling circuit, sensing circuit, acquiring circuit, firing circuit, and AC to AC converter. The system is to automatically adjust the voltage to the induction motor with the variation in the motor load, in order to obtain high operating power factor and efficiency. The system will result in considerable energy-savings when a three-phase induction motor runs under constant light-load or variable-load with low duty ratio.Type: GrantFiled: February 20, 2009Date of Patent: July 10, 2012Assignee: The Hong Kong Polytechnic UniversityInventors: Ka Wai Eric Cheng, Xiangdang Xue
