Publication number: 20100315368Abstract: Disclosed is a method for identifying a number of interactions with a computer input area defined by at least first and second intersecting sets of detection paths. First, indications of which of the detection paths are affected by the interactions are received. Then, for each of the detection path sets, the set's indications of affected detection paths are parsed to identify up to N extents of adjacent, affected detection paths (N?2). A controller having logic to implement the method, and a system incorporating a control system that implements the method, are also disclosed.Type: ApplicationFiled: August 22, 2010Publication date: December 16, 2010Applicant: Avago Technologies ECBU (Singapore) Pte.

Patent number: 7842957Abstract: A transceiver having a light source die, a photodetector die and a substrate is disclosed. The substrate has a first well in which the light source die is mounted and a second well in which the photodetector die is mounted. The substrate has a reflective surface which blocks light leaving the light source from reaching the photodetector unless the light is reflected by an object external to the transceiver. The reflecting surface of the second well in the substrate is shaped to concentrate light received from outside the transceiver onto the photodetector, and in one aspect of the invention it comprises a non-imaging optical element. The light source is powered by applying a potential between first and second contacts on the light source die. A signal is generated between first and second contacts on the photodetector die in response to illumination of the photodetector die.Type: GrantFiled: March 8, 2007Date of Patent: November 30, 2010Assignee: Avago Technologies ECBU IP (Singapore) Pte, Ltd.Inventors: Teck Chai Goh, Deng Peng Chen, Basoor Suresh, Wee Sin Tan, Peng Yam Ng, Sin Heng Lim, Pak Hong Yee

Patent number: 7684029Abstract: In one embodiment, a sensed dataset includes data produced by a plurality of light sensors that have been exposed to a light environment. The data of the sensed dataset corresponds to different ranges of light, and at least a portion of one of the ranges of light is outside the visible (VIS) light spectrum. The sensed dataset is compared to a plurality of known datasets representative of known light environments, and at least one known dataset that is similar to the sensed dataset is identified. In response thereto, an indication of the sensed light environment is provided. Apparatus for implementing this and related methods is also disclosed. In some embodiments, the light sensors are ultraviolet, visible and infrared sensors, and the indication of the sensed light environment is used to control the color of data acquired by an image sensor, or the color of a display backlight.Type: GrantFiled: October 29, 2004Date of Patent: March 23, 2010Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 7507981Abstract: A system for identifying a characteristic of a printing media includes a light source module that has a light emitting diode (LED) and an aspheric lens and a light detection module that has a photodetector and an aspheric lens. The light source module and light detection module are oriented with respect to a printing media such that the focusing points of the respective aspheric lenses are located at a common position on the printing media. The system differentiates between printing media types by applying light to the surface of the printing media and measuring the light that is reflected from the surface.Type: GrantFiled: May 30, 2006Date of Patent: March 24, 2009Assignee: Avago Technologies ECBU IP (Singapore) Pte.

Publication number: 20070132742Abstract: In one embodiment, each of a plurality of optical angle detectors has a plurality of light sensing elements and is positioned at a different location adjacent an optical input area. Each of a plurality of light-control devices is positioned between the optical input area and one of the optical angle detectors, to cause particular rays of light to be mapped to particular light sensing elements of a respective one of the optical angle detectors. The optical angle detectors are positioned to cause each coordinate in the optical input area to be within a field of view of at least two of the optical angle detectors. Other embodiments are also disclosed.Type: ApplicationFiled: December 8, 2005Publication date: June 14, 2007Inventors: Deng-Peng Chen, Wee-Sin Tan, Kuldeep Saxena, Pak Yee, Rani Saravanan

Publication number: 20060132454Abstract: In one embodiment, a touch detection system and method is achieved having high resolution by forming an integrated array of alternating emitters and detectors. Using integration techniques, the detectors can be made much larger than the emitters while the gaps between the emitters and detectors are maintained relatively small. Thus, high resolution is achieved without dramatically increasing the number of emitter/detector pairs. In one embodiment each array is positioned on an edge of a display such that the emitter of one array is lined up (on axis with) a detector of an opposing display. In one embodiment, the touch detection system and method operates to detect the amplitude of signals arriving from opposing arrays so as to precisely determine the location of a touched position. Off-axis scanning can be employed to increase sensitivity.Type: ApplicationFiled: December 16, 2004Publication date: June 22, 2006Inventors: Deng-Peng Chen, Wee-Sin Tan, Kai-Koon Lee, Chee-Heng Wong, Soon-Lee Tan, Masatoshi Yamai, Pak-Hong Yee, Rani Saravanan, Seok Chan
