Patent number: 7615751Abstract: This invention relates generally to the field of motion detection sensors, and in particular to a system and method for adjusting the position of a printed circuit board relative to a focusing element. The invention includes a housing having a front opening and an interior cavity. A focusing element is located within the front opening and the detector is coupled to a printed circuit board located within the interior cavity. A cover is coupled to the printed circuit board and disposed within the interior cavity. A cam is operatively coupled with the cover and the printed circuit board for adjusting the position of the printed circuit board such that the detector's position is adjusted relative to the focusing element.Type: GrantFiled: May 20, 2008Date of Patent: November 10, 2009Assignee: Honeywell International Inc.Inventors: Mark C. Buckley, Bruce Ginn, Raymond E. Daggers, Rand Lenroot, Roy Phi

Publication number: 20090266988Abstract: An infrared detection unit includes a base carrying an infrared sensor element, and a cap configured to be fitted on the base to surround the infrared sensor element. The cap has a top wall with a window in which a semiconductor lens is fitted to collect an infrared radiation onto the infrared sensor element. The semiconductor optical lens is formed from a semiconductor substrate to have a convex lens and a flange which surround said convex lens. An infrared barrier is formed on the semiconductor lens to block the infrared radiation from passing through the boundary between the circumference of the convex lens and the window. Accordingly, the infrared sensor element can receive only the infrared radiation originating from a detection area intended by the convex lens.Type: ApplicationFiled: November 24, 2006Publication date: October 29, 2009Inventors: Yoshiaki Honda, Takayuki Nishikawa, Tomohiro Kamitsu

Patent number: 7597489Abstract: Reflective movable mirrors are used to reflect an image from a desired direction into the lens of a camera. This apparatus is preferably used with infrared (IR) cameras. To capture images from different directions, the orientations of the mirrors are modified. The mirrors are light, requiring only miniature motors and actuators for moving them. The mirrors are also much smaller than the focal plane electronics and the IR lens, requiring much less space for moving them than would be required for moving the camera. This provides a pointing capability for an airframe-fixed IR camera and this capability is provided with minimum additional payload, space and power requirements. The apparatus and method can be used for IR and electro-optical (EO) cameras.Type: GrantFiled: April 12, 2006Date of Patent: October 6, 2009Assignee: Honeywell International Inc.Inventors: Dan T. Horak, Emray R. Goossen, Steven D. Martinez

Patent number: 7592592Abstract: A night vision arrangement for a vehicle incorporating a camera. The camera comprises a window which is substantially transparent to infra-red light, a lens separate from the window, and an infra-red sensor to capture an image received through the window. A beam deflector is provided in alignment with the window to deflect a beam received through the window and directs the deflected beam through the lens on to the sensor. A display unit is provided to display the captured image to a driver of the vehicle.Type: GrantFiled: April 23, 2002Date of Patent: September 22, 2009Assignee: Autoliv Development ABInventor: Dick Eriksson

Publication number: 20090212221Abstract: The disclosed system and apparatus for a sensor support structure generally includes a substantially reflective support strut having discontinuous protrusions on the support surface presented to the field of view of the sensor. These discontinuous protrusions may be suitably configured such that ambient thermal radiation is generally reflected away from the support strut and divergent from acceptance in the sensor's optical train.Type: ApplicationFiled: February 27, 2007Publication date: August 27, 2009Inventors: Eric Fest, Rex Kremer
