Patent number: 8384663Abstract: A system for generating position information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data can be collected in many different ways and may include using a retroreflector as the reflector. The two sets of image data are used to generate position information related to the reflector. In particular, position information related to the reflector is generated by taking the difference between the two set of image data. Because one set of image data includes a stronger indication of the reflector than the other set of image data, the difference between the two sets of image data gives a definitive indication of the reflector's position.Type: GrantFiled: September 14, 2009Date of Patent: February 26, 2013Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Julie E. Fouquet, Richard Earl Haven, John Stewart Wenstrand

Patent number: 7737393Abstract: A system for generating orientation information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data are collected using at least one reflector with some orientation-specific characteristic or a reflector integrated into a device that includes some orientation-specific structural feature. Once collected, the two sets of image data are used to generate orientation information related to the reflector. In particular, orientation information related to the reflector is generated by taking the difference between the two sets of image data.Type: GrantFiled: December 1, 2008Date of Patent: June 15, 2010Assignee: Avago Technologies ECBU IP (Singapore) Pte. Ltd.Inventors: Julie E. Fouquet, Richard Earl Haven, Daniel Usikov, John Stewart Wenstrand

Patent number: 7450250Abstract: An imaging system and method are provided that use imaging information relating to positions of one or more retroreflectors attached to one or more surfaces of an object of interest to determine the shape and/or displacement of the surface or surfaces on which the retroreflector or retroreflectors are located. A variety of types of information may then be ascertained based on the determination as to the shape and/or displacement of the surface of the object, such as the value of some physiological parameter of a patient, internal and external pressure of an object, acoustical vibrations sensed by a microphone, positions of fingertips on a keyboard, etc.Type: GrantFiled: October 11, 2005Date of Patent: November 11, 2008Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Shalini Venkatesh, Richard Earl Haven, John S. Wenstrand

Patent number: 7294815Abstract: A method for generating positional information of an object is carried out by providing a reflector in the object and by providing a personal device containing a light generator and an imager. The personal device is mounted on a person holding the object at a mounting location that is identified to provide a first unobstructed line-of-sight between the light generator and the object and a second unobstructed line-of-sight between the imager and the object.Type: GrantFiled: September 6, 2005Date of Patent: November 13, 2007Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventor: Richard Earl Haven

Patent number: 7280678Abstract: Methods and apparatus for pupil detection are described. First light is emitted from a first light source at a first illumination angle relative to the axis of a detector. Second light is emitted from a second light source at a second illumination angle relative to the axis. The first light and the second light can have substantially equal intensities. The second illumination angle is greater than the first illumination angle. Reflected first light and reflected second light are received at the detector. The difference between the reflected first light and the reflected second light can be determined. The difference can be used to detect the pupils of a subject's eyes.Type: GrantFiled: February 28, 2003Date of Patent: October 9, 2007Assignee: Avago Technologies General IP Pte LtdInventors: Richard Earl Haven, David James Anvar, Julie Elizabeth Fouquet, John Stewart Wenstrand

Patent number: 6798939Abstract: Bubble stability within an optical switch is enhanced by controlling the expansion or movement of a bubble from a liquid-containing trench into available adjacent spacing. Typically, the adjacent spacing is formed between an optical waveguide substrate and a heater substrate, where the heater substrate includes a microheater for forming the bubble. The bubble enhancement is provided by intentionally altering surface features along at least one of the substrates.Type: GrantFiled: March 14, 2002Date of Patent: September 28, 2004Assignee: Agilent Technologies, Inc.Inventors: Frederick Austin Stawitcke, Shalini Venkatesh, Datong Chen, Richard Earl Haven, Mark Andrew Troll, David James Anvar
