Patent number: 7489351Abstract: An optical detector uses an auxiliary integrating capacitor is used to determine the optical flux rate when the charge on the well capacitor approaches or reaches linear saturation. The voltage across the primary linearly operating integrating well capacitor is monitored to detect its linear saturation. The auxiliary capacitor charges at a predetermined rate from the start of the integration interval, and the voltage across it is sampled when the monitored voltage across the primary linear integrating well capacitor reaches linear saturation. The voltage across the auxiliary capacitor at this point is function of the rate at which the primary well capacitor was filling, and this voltage is processed as the illumination level for the integration period.Type: GrantFiled: January 21, 2005Date of Patent: February 10, 2009Assignee: BAE Systems Information And Electronic Systems Integration Inc.Inventor: Robert D. Frey, Jr.

Patent number: 7307251Abstract: A light source is injected into an optical path of a camera to provide a controlled background to insure optimum uniformity of performance of the camera. An optical system, camera, image background measurement system, source intensity control, and light source comprise a closed loop control around the light source to control an operating point of the camera. Intensity of the light source is decreased as intensity of a background flux is increased.Type: GrantFiled: January 21, 2005Date of Patent: December 11, 2007Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Robert D. Frey, Jr., Walter P. Watson, William E. Shaw

Patent number: 6774349Abstract: The invention provides a golf feedback system. A mat is used to determine player foot position, and a 3D golf tracking system tracks golf balls hit from the mat to determine (a) a ground ball track and (b) a player orientation axis, based on the foot position and relative to the mat. The system further determines information indicative of how well the ground ball track correlated to the orientation axis. Preferably, a golfer using the system is led through a plurality of pin target locations in a simulated golf game. The system evaluates and stores information such as slice and hook, accuracy, player orientation axis and ball carry distance such that the player can evaluate his/her game individually or against one or more other players.Type: GrantFiled: February 19, 2002Date of Patent: August 10, 2004Inventors: Curtis A. Vock, Kevin J. Grealish, Robert D. Frey, George Nauck, Charles M. Marshall

Patent number: 6320173Abstract: The invention monitors the driving range and tracks golf balls from users at the driving range and informs those users of characteristics such as driving distance. A solid state camera images the range, and preferably one or more tee-off positions, and collects frames of image data to track a ball's motion through space. Simulation routines augment that track and assist in isolating the start location as well as where the ball lands, or would have landed had it not been obstructed (e.g., by a net). Preferably, the invention also determines the ball's position in 3-D to increase the accuracy. In one technique, two or more solid state cameras are used, and synchronized, to specify stereoscopic imaging. In another technique, the ball's energy or physical extent is used to determine an absolute distance between the camera and the ball. A computer at the club house monitors the entire system and further manages a network including an array of displays at the several tee off positions.Type: GrantFiled: May 15, 2000Date of Patent: November 20, 2001Inventors: Curtis A.

Patent number: 5925875Abstract: An apparatus and method for reducing fixed pattern noise in a planar array that includes an array of image responsive detectors, a dithering mechanism for dithering an observed image relative to the array, a high pass filter, and an image restorer. The fixed pattern noise in an observed image is reduced by dithering the observed image across a plurality of detectors forming a planar array, filtering the detector responses with the high pass filter, and passing the filtered signals through the image restorer. A correcting element can be used to iteratively update the fixed pattern noise estimate. In addition, a voter or a frame averager can be included to reduce errors that might adversely effect the fixed pattern noise estimate.Type: GrantFiled: April 18, 1997Date of Patent: July 20, 1999Assignee: Lockheed Martin IR Imaging SystemsInventor: Robert D.
