Patent number: 9645386Abstract: MEMS shutters are applied in displays and imaging devices. In a display, sensors may detect light from a light source that is back-reflected by a MEMS shutter and/or ambient light that enters through the MEMS shutter. The sensors may be used to monitor performance of the light source and/or ambient lighting conditions. In an imaging device, MEMS shutters may be applied to selectively block light to prevent overexposed areas within an image.Type: GrantFiled: November 29, 2012Date of Patent: May 9, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Terence Ka Wing Lau, William Brent Wilson, Robin Atkins, Henry Hang Kei Ip, Gregory John Ward, Douglas Campbell, Neil W.

Patent number: 8633441Abstract: A method of aligning a die when the die is held with a circuit pattern on a first side of the die facing away from an infrared light source, wherein infrared light from the infrared light source is projected onto a second side of the die opposite to the first side such that the infrared light passes through a body of the die. From the second side of the die, an image of the infrared light reflected from the circuit pattern is detected and captured. Thereafter, an alignment of the die from the captured image of the die is determined.Type: GrantFiled: September 2, 2009Date of Patent: January 21, 2014Assignee: ASM Assembly Automation LtdInventors: Ran Shi Wang, Wing Hong Leung, Siu Wing Lau

Publication number: 20060155418Abstract: Direct slicing of CAD models to generate process planning instructions for solid freeform fabrication may overcome inherent disadvantages of using STL format in terms of the process accuracy, ease of file management, and incorporation of multiple materials. This paper will present the results of our development of a direct slicing algorithm for layered freeform fabrication. The direct slicing algorithm was based on a neutral, international standard (ISO 10303) STEP-formatted NURBS geometric representation and is intended to be independent of any commercial CAD software. The following aspects of the development effort will be presented: 1) Determination of optimal build direction based upon STEP-based NURBS models; 2) Adaptive subdivision of NURBS data for geometric refinement; and 3) Ray-casting slice generation into sets of raster patterns.Type: ApplicationFiled: April 12, 2004Publication date: July 13, 2006Applicant: Therics, Inc.Inventors: Thomas Bradbury, Binil Starly, Wing Lau, Wei Sun, Alan Lau, Adolphe Youssef, Christopher Gaylo

Publication number: 20050220023Abstract: We formulate the network-wide traffic measurement/analysis problem as a series of set-cardinality-determination (SCD) problems. By leveraging recent advances in probabilistic distinct sample counting techniques, the set-cardinalities, and thus, the network-wide traffic measurements of interest can be computed in a distributed manner via the exchange of extremely light-weight traffic digests (TD's) amongst the network nodes, i.e. the routers. A TD for N packets only requires O(loglog N) bits of memory storage. The computation of such O(loglog N)-sized TD is also amenable for efficient hardware implementation at wire-speed of 10 Gbps and beyond. Given the small size of the TD's, it is possible to distribute nodal TD's to all routers within a domain by piggybacking them as opaque data objects inside existing control messages, such as OSPF link-state packets (LSPs) or I-BGP control messages.Type: ApplicationFiled: August 2, 2004Publication date: October 6, 2005Inventors: Muralidharan Kodialam, Tirunell Lakshman, Wing Lau

Publication number: 20050111367Abstract: In a network including a centralized controller and a plurality of routers forming a security perimeter, a method for selectively discarding packets during a distributed denial-of-service (DDoS) attack over the network. The method includes aggregating victim destination prefix lists and attack statistics associated with incoming packets received from the plurality of routers to confirm a DDoS attack victim, and aggregating packet attribute distribution frequencies for incoming victim related packets received from the plurality of security perimeter routers. Common scorebooks are generated from the aggregated packet attribute distribution frequencies and nominal traffic profiles, and local cumulative distribution function (CDF) of the local scores derived from the plurality of security perimeter routers are aggregated.Type: ApplicationFiled: November 26, 2003Publication date: May 26, 2005Inventors: Hung-Hsiang Jonathan Chao, Mooi Chuah, Yoohwan Kim, Wing Lau
