Publication number: 20080310177Abstract: Compact illumination systems, particularly for aircraft, use efficient beam forming optical light emitting diode arrangements combined with beam turning and beam splitting prism optics and optional aspheric reflectors to direct light in a cross cabin or cross bin lighting application. The LED based compact illumination devices are positioned to shine on opposite storage/stowage bins without being directly visible to a passenger. The devices are effective for illuminating ceiling structures as well as across the aisles of a passenger cabin, thus creating a cross-bin lighting system.Type: ApplicationFiled: June 14, 2007Publication date: December 18, 2008Inventor: Roy Clark

Publication number: 20080304273Abstract: Interior lighting and illumination systems for aircraft, particularly commercial passenger airplanes. Efficient beam forming optical light emitting diode arrangements having offset apertures for maximizing effectiveness are positioned in the ceiling panels above the aisles between sets of seats in the passenger cabins for cross bin illumination of stowage areas. The efficient beam forming optical LED devices are positioned to shine on opposite storage/stowage bins and are positioned to overcome line of height light source restrictions such as may be imposed by a valence. The devices are effective for illuminating across the aisles, thus creating a cross-bin lighting system.Type: ApplicationFiled: June 8, 2007Publication date: December 11, 2008Inventor: Roy Clark

Patent number: 7449312Abstract: A method for conducting a nucleic acid amplification reaction, said method comprising forming an amplification reaction mixture in the presence of sufficient of a pyrophosphate salt to prevent primer extension taking place, digesting said pyrophosphate salt with a pyrophosphatase enzyme (PPase), and subjecting said reaction mixture to conditions such that an amplification reaction may proceed. This can be used as a “hot start” amplification. Particular novel pyrophosphatase enzymes for use in the method are also described and claimed.Type: GrantFiled: August 17, 2005Date of Patent: November 11, 2008Assignee: The Secretary of State for Defense in Her Britannic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventors: Duncan Roy Clark, Suzanne Patricia Vincent

Patent number: 7409525Abstract: A technique coordinates access to shared data on a remote device from a local device having local physical memory. The technique involves observing a page table entry (PTE) on the remote device. The PTE is stored in a page table used for managing virtual to physical address translations and handling page faults between semiconductor memory and magnetic disk drive memory on the remote device. The technique further involves blocking access to the shared data from the local device when the PTE indicates that shared data corresponding to the PTE is in use on the remote device. The technique further involves moving the shared data into the local physical memory from the semiconductor memory of the remote device, and providing access to the shared data in the local physical memory when the PTE indicates that shared data corresponding to the PTE is not in use on the remote device.Type: GrantFiled: March 29, 2006Date of Patent: August 5, 2008Assignee: EMC CorporationInventors: Roy Clark, David W. DesRoches

Patent number: 7333206Abstract: In accordance with an embodiment of the present invention, an apparatus for measuring light scatter loss from a test piece includes a light source, an optical cavity including the test piece and at least one mirror located along a path, and a light detector. The cavity receives an input beam from the light source, circulates a beam within the cavity as a circulating beam, and produces an output beam. Irregularities on the surface of the test piece result in a progressive diffusion of the circulating beam about the path. The light detector provides an output signal based on the intensity of the output beam. The output signal has an initial slope that determines a first saturation value. The output signal has a second saturation value. The difference between the first saturation value and the second saturation value provides a scatter loss measurement.Type: GrantFiled: April 7, 2005Date of Patent: February 19, 2008Assignee: The Bowing CompanyInventor: Roy Clark

Patent number: 7271332Abstract: A device for mixing the outputs of two sensors. The device includes a first input for receiving a signal from at least one first sensor, a second input for receiving a signal from at least one second sensor, a low pass filter for passing signal components of the first input signal below a first frequency, a high pass filter for passing signal components of the second input signal above a second frequency and a mixing circuit for combining the signals passed by the low pass filter and the high pass filter to form a combined output signal. The mixing device may be incorporated into a pre-amplifier for use with an electrified acoustic guitar, or other acoustic stringed instrument, having an under saddle sensor and a second sensor attached to a body portion of the guitar, such as the soundboard. In this way, lower frequencies are taken from the under saddle sensor and higher frequencies are taken from the body/soundboard sensor.Type: GrantFiled: June 28, 2004Date of Patent: September 18, 2007Assignee: Australian Native Musical Instruments Pty.

Patent number: 7102824Abstract: An optical element is provided that may be used for collecting optical radiation incident at large angles of incidence. The element may include a grating window formed of grating elements that may collect large incident angle radiation and reflect that radiation, e.g., under total internal reflection in a substantially normal direction. A lens or lens array may be used to collect the internally reflected radiation and focus that radiation to a detector. Example detectors include infrared detectors. The element may be formed to collect, reflect, and redirect optical radiation incident at angles above 45° as measured from a surface normal to a detector oriented substantially at normal incidence. The detected signal from the optical element may be used to control systems within an aircraft or other vehicle capable of flight.Type: GrantFiled: May 13, 2004Date of Patent: September 5, 2006Assignee: The Boeing CompanyInventors: Roy Clark, Douglas C.
