In one embodiment the LPS system utilizes a light weight portable goggle type eyewear. In yet another embodiment the LPS system is comprised of contact lenses worn by the user. The LPS system may be used in all light transmissive surfaces where the penetration of laser light is not desired, such as aircraft, spacecraft, vessel, train, and automotive windshields, etc. The LPS system may also be utilized as a replacement window for structures where laser light penetration is undesired. The protection panels utilize Liquid Crystal Displays (LCD) that are activated by laser sensors by means of a microprocessor and power supply means.Type: GrantFiled: January 7, 2005Date of Patent: April 10, 2007Inventor: Mark R.

Patent number: 7196690Abstract: According to one aspect of the invention, a movable cursor control device is provided for controlling a cursor on a display screen of a digital processing system. One exemplary cursor control device comprises a housing, an electromagnetic emitting device coupled to the housing, and an electromagnetic detector coupled to the housing. The electromagnetic detector detects reflections of signals emitted from the electromagnetic emitting device and determines when the housing has been lifted from a surface. In another aspect of the invention, an exemplary method is provided for controlling a cursor on a display screen of a digital processing system. The exemplary method includes holding the cursor relative to an object on the display screen using a cursor control device activated by a user, detecting that the user no longer activates the cursor control device, and detecting that the user has lifted the cursor control device from a surface when the cursor control device is no longer activated by the user.Type: GrantFiled: September 22, 2004Date of Patent: March 27, 2007Assignee: Apple Inc.Inventors: Abraham S. Farag, Bartley K. Andre, Benjamin B. Lyon, Richard D. Cappels, Sr., Jeffrey B. Doar

Patent number: 7168047Abstract: A mouse for controlling movements on a display screen is disclosed. The mouse includes a housing that is gripped by a user during manipulation of the mouse and a sensor configured to detect the presence of a user's hand or portions thereof located outside of and in close proximity to a predetermined portion of the housing. The signals produced by the sensor are used to control functionalities of the mouse, as for example, switching between a cursor control mode and a scroll/pan control mode of the mouse.Type: GrantFiled: May 28, 2002Date of Patent: January 23, 2007Assignee: Apple Computer, Inc.Inventor: Brian Q. Huppi

Patent number: 7148892Abstract: A system and method is provided for facilitating navigation techniques in a three-dimensional virtual environment. The present invention couples input driving techniques to the state of one or more workspace variables (e.g., object state, virtual body state, environment state) to change the user's viewing context within a single input control motion. Modification of the user's viewing context allows navigation to various positions and orientations with out the need to be provided with that viewing context prior to navigation. The modification of the user's viewing context also allows for single input motion employing the same input drive controls.Type: GrantFiled: June 3, 2005Date of Patent: December 12, 2006Assignee: Microsoft CorporationInventors: George G. Robertson, Mary P. Czerwinski, Desney Tan

Patent number: 7119323Abstract: An optical navigation system. The optical navigation system includes an image sensor capable of optical coupling to a surface of an object, a data storage device, and a navigation circuit. The data storage device is capable of storing successive images captured by the image sensor. The navigation circuit includes a first digital circuit capable of determining an optical displacement estimate for a relative displacement between the image sensor and the object obtained by comparing the images, a second digital circuit capable of determining a mechanical displacement estimate for the relative displacement obtained from consideration of a mechanical characteristic associated with the optical navigation system, and a third digital circuit capable of determining an adjusted displacement estimate obtained from the optical displacement estimate and the mechanical displacement estimate.Type: GrantFiled: March 18, 2005Date of Patent: October 10, 2006Assignee: Avago Technologies ECBU IP (Singapore) Pte. Ltd.Inventors: Michael J. Brosnan, Tong Xie

Patent number: 7034805Abstract: An optical trackball is disclosed that is easy to operate without been worried about the contamination on the contacting shifts of encoders inside the trackball. When a distal motion from a user to rotate an operating ball having an uneven surface on the trackball, an image-detecting module will detect the varying of the reflected image from an illuminated portion of the uneven surface, causing the correspondingly moving of the cursor on the computer display.Type: GrantFiled: November 2, 2001Date of Patent: April 25, 2006Assignee: Kye Systems Corp.Inventor: Yu-Quan Su

Patent number: 7012201Abstract: A rotary encoder includes a roller having substantially cylindrical shape, an inner shaft, a translucent cylindrical light guide shaft, a pair of holders, a light-emitting device, and a light-detecting device. The inner shaft is inserted and secured to a center hole of the roller, and has a slit at one end along a direction parallel to the axis thereof. The light guide shaft is inserted in the inner shaft so that one end of it is surrounded by the slit, and this guide has a first and second planes, and a first and second inclined planes. The first and second planes are formed on a lower side at both ends of the light guide shaft in parallel to the axis of the shaft. The first and second inclined planes are formed above the first and second planes at an angle of 45 degrees to the axis of the shaft, so that the two planes are substantially orthogonal to each other.Type: GrantFiled: February 10, 2005Date of Patent: March 14, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Kodani, Takashi Tomago

Patent number: 6987505Abstract: A single-piece component rotatably supports a scroll wheel and includes an integral follower arm extending into a well within which the scroll wheel rotates. Formed on a circumferential surface of the scroll wheel are regularly spaced detents or other structures forming regularly spaced regions of alternating height. Located on an end of the follower arm is a follower which moves in and out of the detents as the scroll wheel rotates, with the arm biasing the follower against movement out of the detents. The carriage may also include pivots for relative movement of the carriage and scroll wheel assembly with respect to a housing, and a tab for actuating a switch.Type: GrantFiled: June 3, 2002Date of Patent: January 17, 2006Assignee: Microsoft CorporationInventor: James Y.
