Patent number: 7091930Abstract: A sensor unit (F) has at least a first and second sensor (10, 12) arranged along a sensor axis (14). A head adapter (16) provides support to mount at least one selected device about a user's cranium (18). A securing module (20) is attached to the sensor unit for mounting the sensor unit (F) to the head adapter (16). The sensor unit (F) is to be mounted above an ocular axis (22) formed between a pair of eyes (24) of the user (U) when the sensor unit (F) is attached to the head adapter element (16). When the sensor unit (F) is secured to the user (U) with the head adapter element (16), the sensor axis (14) is essentially perpendicular to the user's ocular axis (22).Type: GrantFiled: July 30, 2004Date of Patent: August 15, 2006Assignee: Litton Systems, Inc.Inventors: Timothy E.

Patent number: 7021522Abstract: Mating faces of a microchannel plate (MCP) (50) and a multi-layer ceramic body (80) unit are deposited with a thin film having protuberances (84) using a suitable metal selected for optimum diffusion at a desired temperatures and pressure. The metallized MCP (50) and multi-layer ceramic body (80) unit are then aligned and placed in a bonding fixture (F) that provides the necessary force applied to the components to initiate a diffusion bond at a desired elevated temperature. The bonding fixture (F) is then placed in a vacuum heat chamber (V) to accelerate the diffusion bonding process between the MCP (50) and the multi-layer ceramic body unit (80).Type: GrantFiled: January 24, 2005Date of Patent: April 4, 2006Assignee: Litton Systems, Inc.Inventors: Niels F.

Patent number: 6624406Abstract: The present invention comprises a method for detecting photons and generating a representation of an image. A photocathode receives photons from the image. The photocathode discharges electrons in response to the received photons. A microchannel plate is located no more than about 125 microns from the photocathode. The microchannel plate has an unfilmed input face and an output face. The microchannel plate receives the electrons from the photocathode and produces secondary emission electrons which are emitted from the output face. A screen receives the secondary electrons and displays a representation of the image.Type: GrantFiled: June 4, 1999Date of Patent: September 23, 2003Assignee: Litton Systems, Inc.Inventors: Joseph P. Estrera, Michael J. Iosue, Timothy W. Sinor

Patent number: 6297494Abstract: The present invention comprises a method for detecting photons and generating a representation of an image. A photocathode receives photons from an image. A power supply to the photocathode is gated such that the photocathode is switched between an on state and an off state. The photocathode discharges electrons in response to the received photons while the photocathode is in the on state. A microchannel plate is located no more than about 125 microns from the photocathode. The microchannel plate has an unfilmed input face and an output face that receives the electrons from the photocathode. The microchannel plate produces secondary emission electrons which are emitted from the output face. A screen receives the secondary electrons and displays a representation of the image.Type: GrantFiled: June 4, 1999Date of Patent: October 2, 2001Assignee: Litton Systems, Inc.Inventors: Joseph P.

Patent number: 6049168Abstract: The present invention discloses a method for manufacturing a photon detector and image generator. First, a screen operable to display a visual image based on a received signal is provided. The screen is then scrubbed. Next, an unfilmed microchannel plate having an input face and an output face is provided. The microchannel plate is baked in a vacuum chamber and a tube assembly is formed by attaching the microchannel plate to the screen. The tube assembly is scrubbed using an electron gun. Next, a photocathode, having an input side and an output side, is attached to the assembly such that the output side of the photocathode faces the input face of the microchannel plate in order to form a final tube, wherein the tube has a lifetime greater than 7,500 hours.Type: GrantFiled: June 4, 1999Date of Patent: April 11, 2000Assignee: Litton Systems, Inc.Inventors: Michael J.
