Publication number: 20080179523Abstract: An imaging system (20) includes an array (24) of photonic band gap material cells. The band gap material has an absorption edge at about the emission frequency of a source (22) of electromagnetic energy. Images from a field of view (26) directed onto the photonic band gap array (24) increase the temperature of the illuminated cells, shifting the absorption edge frequency for those cells. A focal plane array (28) detects the electromagnetic radiation transmitted through the photonic band gap array (24) from the source (22). The intensity of the transmitted radiation is proportional to the shift in the photonic band gap edge.Type: ApplicationFiled: January 30, 2007Publication date: July 31, 2008Applicant: RAYTHEON COMPANYInventors: Delmar L.

Patent number: 7397055Abstract: The Smith Purcell effect, in which a beam of electrons passes close to a conducting grating and induces electromagnetic radiation from the grating surface, can be used as a source of THz radiation. A grating composed of negative index metamaterial (NIM) enhances the output of the Smith Purcell source. Of particular interest is the use of a NIM grating in a Smith-Purcell source to provide a tunable coherent CW source of terahertz (THz) radiation.Type: GrantFiled: May 2, 2005Date of Patent: July 8, 2008Assignee: Raytheon CompanyInventors: Delmar L.

Publication number: 20080084604Abstract: A system and method for modulating the frequency of electromagnetic radiation utilizes a frozen shockwave in a photonic band gap structure. The structure provides a discontinuity in lattice constant that functions as a shockwave, and that does not shift its position within the structure. In addition the modulation device or structure includes an acoustic pulse generator, such as a piezoelectric transducer coupled to one end of the photonic band gap structure. The acoustic pulse generator may be driven to produce a periodic pulse in the photonic band gap structure. The frozen shockwave, a defect or discontinuity in the photonic band gap structure, is used to hold incoming electromagnetic radiation in place. The acoustic pulse passing through the photonic band gap structure Doppler shifts the frequency of the radiation. The frequency-shifted radiation is then ejected out of the frozen shockwave portion of the photonic band gap structure.Type: ApplicationFiled: October 10, 2006Publication date: April 10, 2008Inventors: Delmar L. Barker, William R. Owens, Abram G. Young

Patent number: 7292740Abstract: An apparatus (10) and method for dynamic frequency control of a photonic band gap crystal includes an acoustic band gap crystal (12) having a defect site (14), a photonic band gap crystal (20) in the defect site of the acoustic band gap crystal (12), and a sound wave generator (40) coupled to the acoustic band gap crystal (12). Consequently, acoustic waves in the acoustic band gap crystal (12) can be used to controllably alter transmission properties of the photonic band gap crystal (20) and thereby modulate the transmission of electromagnetic radiation through the photonic band gap crystal (20). Acoustic waves in the acoustic band gap crystal (12) can squeeze the photonic band gap crystal (20) to change its properties, including one or more of lattice constant, symmetry, and optical refractive index contrast.Type: GrantFiled: January 18, 2007Date of Patent: November 6, 2007Assignee: Raytheon CompanyInventors: Delmar L.

Patent number: 7257333Abstract: A band gap discontinuity is propagated across a Photonic Crystal (PC) to capture thermal energy in a region near the primary emission wavelength of the Planck spectral distribution and transfer that energy to a different spectral region where it is emitted. To extend the range of frequency shifting beyond the width of a single band gap, the intrinsic control parameters (e.g., lattice geometry factors, scattering element geometric factors, and variations in the index of refraction) are spatially varied across the PC to form a band gap gradient. Propagation of the band gap discontinuity, starting in the infrared wavelength region where the thermally generated electromagnetic energy is concentrated and propagating towards the long wavelength region, locally captures the thermal electromagnetic radiation, shifts it downwards in frequency, and pushes the lower-frequency thermal electromagnetic radiation on to the next region. The same principles apply to shift the frequency to shorter wavelengths.Type: GrantFiled: January 6, 2005Date of Patent: August 14, 2007Assignee: Raytheon CompanyInventors: Ross D Rosenwald, Nitesh N. Shah, Delmar L. Barker, William R. Owens, Hao Xin

Patent number: 7162285Abstract: A detector for detecting telephone-activated devices, such as cellular telephones used for remotely triggering explosive devices, includes a transmitter for generating and transmitting a pseudo base station signal corresponding to a base station for a telephone-activated device, and a receiver for receiving and detecting a response signal transmitted by the telephone-activated device. At least part of the transmitter and at least of the receiver may be located within a shield of conductive material, such as a cone-shaped metal shield, that aids in localizing and directing the transmitting of the pseudo base station signal toward an object to be interrogated (with regard to whether or not it contains a telephone-activated device in an idle state). The detector has a response unit for providing a response when a telephone-activated device is detected, such as providing an alarm to an operator or interdicting operation of the telephone-activated device.Type: GrantFiled: September 19, 2003Date of Patent: January 9, 2007Assignee: Raytheon CompanyInventors: William R.

Patent number: 7078697Abstract: Although THz radiation is naturally emitted by hot objects, the intensity levels are too weak to be considered as a practical THz source for most applications. Photonic crystal structures are used to modify the thermal emission peak associated with the standard Planck blackbody spectral distribution so that the THz region is dramatically enhanced. The photonic crystal core is preferably combined with variable Q defect cavities and a wave guiding and power combining structure so that the radiated THz energy is efficiently collected and directed to an output antenna. Higher THz emissions are realized by embedding a finer (higher frequency) photonic crystal structure within a coarser (lower frequency) structure.Type: GrantFiled: October 7, 2004Date of Patent: July 18, 2006Assignee: Raytheon CompanyInventors: Delmar L.

Patent number: 5428657Abstract: The invention is a method and apparatus for identifying and pinpointing the location of unwanted pieces of material or defects in, for example, de-boned poultry pieces. The poultry pieces to be inspected are carried on a conveyor and passed under an impinging collimated X-ray beam. The Rayleigh scattering resulting is detected and measured, as is the Compton back scattering and the data is processed in a processing unit to determine the location and type of foreign matter involved. The ratio of the Rayleigh and Compton scattering is also determined and used to verify the identity of the foreign material. Transmitted X-rays, i.e., radioscopy, are used to normalize the data, and to aid in a pinpointing of the location of the unwanted material.Type: GrantFiled: March 22, 1994Date of Patent: June 27, 1995Assignee: Georgia Tech Research CorporationInventors: Chris D.

Patent number: 4876854Abstract: A thermally powered electrical generating system for use in a space vehicle is disclosed. The rate of storage in a thermal energy storage medium is controlled by varying the rate of generation and dissipation of electrical energy in a thermally powered electrical generating system which is powered from heat stored in the thermal energy storage medium without exceeding a maximum quantity of heat. A control system (10) varies the rate at which electrical energy is generated by the electrical generating system and the rate at which electrical energy is consumed by a variable parasitic electrical load to cause storage of an amount of thermal energy in the thermal energy storage system at the end of a period of insolation which is sufficient to satisfy the scheduled demand for electrical power to be generated during the next period of eclipse. The control system is based upon Kalman filter theory.Type: GrantFiled: May 27, 1988Date of Patent: October 31, 1989Assignee: Sundstrand Corp.Inventor: William R. Owens

Patent number: 4868412Abstract: A control system is provided in which a plurality of independent control elements are each capable of generating a random value and determining a time delay as a function of that random value. Each of the control elements accesses the magnitude of a sensed parameter and responds to that magnitude. When correction of the sensed parameter is required, each independent control element senses the need for a correction and delays by an amount of time determined randomly and independent from all other control elements. After the randomly determined time delay has elapsed for each control element, that control element again accesses the magnitude of the sensed parameter and, if correction is still required, changes the connection status of an associated switch. In a preferred embodiment of the present invention, the control element interrogates the status of its associated switch to determine if actuation would benefit the correction of the magnitude of the sensed parameter.Type: GrantFiled: October 28, 1988Date of Patent: September 19, 1989Assignee: Sundstrand CorporationInventor: William R. Owens

Patent number: 4814934Abstract: A voltage fault detector (10) for producing a trip signal causing switching from a first AC voltage source (12) to a second AC voltage source (14) is disclosed. A plurality of comparators (18,20,22) monitor a signal which is proportional to the magnitude of the voltage of a first AC voltage source (12) to determine if sample values fall within predetermined ranges. A counter (30) counts the number of samples falling outside the predetermined range to generate the trip signal when the count reaches a predetermined limit. The counter (30) is augmented for each sample which is outside the predetermined range and decremented for each sample which is within the predetermined range.Type: GrantFiled: December 24, 1987Date of Patent: March 21, 1989Assignee: Sundstrand Corp.Inventors: Gregory D.

Patent number: 4812943Abstract: An overcurrent protection system (10) for a power supply is disclosed. The system monitors the instantaneous flow of current between a power supply (12) and an electrical load (16) to detect when the flow of current exceeds a maximum rated amount. A counter (30) is used for counting the number of times that samples of the flow of current exceed the maximum rated amount synchronous with zero current crossing to generate a trip signal when a predetermined count is reached which disconnects the power supply (12) from the load. The counter (30) is decremented each time a predetermined time interval elapses in which the flow of current above the maximum rate is not detected as measured from a point of zero current flow between the power supply (12) and the electrical load (14). The invention may be used for both AC and DC power supplies.Type: GrantFiled: December 24, 1987Date of Patent: March 14, 1989Assignee: Sundstrand Corp.Inventors: Gregory D. Jones, William R. Owens, Clifford G. Thiel, Clive M. Danby

Patent number: 4811136Abstract: A power supply system for processing current and voltage faults is disclosed. Each phase of a first power source (12) and each phase of a second power source (28) has a pair of switches (60, 64) for controlling the conduction of current from the phase of the power source to a phase load (29). In each of the phases of the first power source (12), a first switch (60) is controlled by a first control signal which has a high level when a voltage fault or current fault condition does not exist. When either a voltage fault or a current fault condition exists, the first switch (60) is turned off. The second switch (64) is turned on by a second control signal during a determination of whether a current fault exists. Furthermore, a logic network causes the first control signal to assume the second level in response to any one of an RMS over/under voltage fault, an instantaneous overcurrent fault, an I.sup.Type: GrantFiled: December 24, 1987Date of Patent: March 7, 1989Inventors: Gregory D.
