Publication number: 20240077282Abstract: An anti-cant indicator assembly, components thereof, and associated methods. The anti-cant indicator assembly indicates the orientation of a weapon with respect to vertical. The anti-cant indicator assembly includes a mount configured to mount to the weapon, a level including a vial containing a bubble and a pivot connection connecting the level to the mount. The pivot connection is configured to permit movement of the level with respect to the mount about the pivot connection between an operational position in which the bubble can be referenced by the user for indicating orientation of the weapon with respect to vertical, and a stowed position different from the operational position. The pivot connection can include a retainer configured to releasably retain the level in at least one of the operational position or the stowed position. The level can be selectively movable with respect to the mount to calibrate the anti-cant indicator.Type: ApplicationFiled: November 10, 2023Publication date: March 7, 2024Applicant: AOB Products CompanyInventors: Mike Lindsay, Michael Cottrell, James Tayon, Timothy S.

Patent number: 10377653Abstract: An economical method for recovering phosphate or phosphate and nitrogen from liquid streams. A liquid containing phosphate is introduced into a culture of autotrophic microorganisms in the presence of natural or artificial light, thereby producing a liquid effluent with elevated pH and reduced alkalinity. The alkalinity is reduced through the consumption of bicarbonate/carbonate by the autotrophic microorganisms. The effluent is then chemically treated with low-cost chemicals to provide Ca++ or Mg++ ions necessary to form a phosphate precipitate such as calcium phosphate or magnesium-ammonium-phosphate (MAP). The autotrophic microorganisms can be cultivated in ponds, lagoons, or photobioreactors. The pH of the culture is adjustable within a preferred range of 7.5 to 10.5 by adjusting the photobioreactor operation.Type: GrantFiled: September 29, 2017Date of Patent: August 13, 2019Inventor: Dennis A.

Patent number: 8637304Abstract: An economical method for recovering nitrogen from liquid waste using autotrophic organisms and minimal energy inputs and without chemical additives. Solids are separated from anaerobically digested liquid waste. The resulting translucent liquid is introduced to a culture of autotrophic microorganisms in the presence of natural or artificial light, thereby accumulating biomass and producing a liquid effluent with elevated pH. The elevated-pH, liquid effluent is heated and stripped of ammonia, thereby producing a water vapor and stripped ammonia gas stream. The water vapor ammonia gas stream is condensed to form a liquid/ammonia condensate. The autotrophic microorganisms are advantageously cultivated in a photobioreactor comprising a plurality of axially spaced-apart, growth plates mounted for rotation to a shaft. The pH of the culture is adjustable within a preferred range of 8.0 to 10.5 by adjusting the light intensity and rotational speed.Type: GrantFiled: December 1, 2011Date of Patent: January 28, 2014Inventor: Dennis A.

Patent number: 8526811Abstract: A photodiode array includes a plurality of monitoring photodiodes capable operating in a voltage mode configuration each able to provide a voltage indicating an intensity of an incident light. Integrated with the monitoring photodiodes is a reference diode configured to produce reference voltages in response to reference currents supplied to that diode. The monitoring photodiodes and the reference diode may be integrated and have the same current-voltage characteristics and the same temperature, for example by fabricating them on the same substrate. The reference diode is supplied with the reference currents in dark manner, meaning without incident light impinging on the reference diode. The resulting reference voltages, the reference source currents, and the measured photo-voltage from the monitoring photodiodes are than used to determine an optical power value at any temperature within the operation temperature range.Type: GrantFiled: October 20, 2009Date of Patent: September 3, 2013Assignee: Sumitomo Electric Device Innovations, U.S.A., Inc.Inventors: Chuan Xie, Jiaxi Kan, Dennis Burke, Daniel Zhu

Optoelectronic module with integrated monitoring photodiode array for a parallel optical transmitter
Patent number: 7961770Abstract: A power monitoring system uses a low loss reflective element to partially split the output laser beams from an array of laser sources, in a parallel configuration, to produce a monitor beams for each laser source. Each of these monitor beams may propagate within the reflective element in a lossless manner under total internal reflection and into one of a plurality of photodiodes that sense an optical characteristic such as output beam intensity, where this sensed signal is then used as part of a feedback control to control operation of the laser sources in the array.Type: GrantFiled: March 17, 2010Date of Patent: June 14, 2011Assignee: Emcore CorporationInventors: Daniel Zhu, Jason O'Neil, Chuan Xie, Dennis Burke, Jiaxi Kan, Gary Basey -

Patent number: 7811455Abstract: A method for the removal and sequestration of ammonia nitrogen from anaerobic fermentation effluent while producing a higher BTU biogas. The method includes the steps of removing the slurry from the digester, stripping the ammonia from the slurry or portion thereof with a high BTU biogas, blending the stripped ammonia with the digesters biogas to remove the carbon dioxide and precipitate ammonium bicarbonate/carbonate as a solid while producing a high Btu biogas, a portion of which is used to strip the ammonia and CO2 from the slurry. The process removes ammonia nitrogen from the digester effluent while producing a high Btu biogas and a solid ammonium bicarbonate/carbonate product. Ammonia stripping is accomplished with a recycled stripping gas deficient in CO2 and ammonia that is capable of removing the CO2 and ammonia from solution by virtue of the lower partial pressures of CO2 and ammonia in the stripping unit.Type: GrantFiled: June 5, 2008Date of Patent: October 12, 2010Inventor: Dennis A.

Publication number: 20070102352Abstract: A process for the recovery of nitrogen from anaerobically digested liquid waste and for the collection of the nitrogen as nitrate compounds that can be used to produce fertilizer and compost, includes stripping ammonia from anaerobically digested liquid waste, and converting the ammonia into nitrates via nitrification. The stripping gas is heated above ambient atmospheric temperature to improve nitrogen recovery. The heat can be reclaimed by burning gases generated during the anaerobic digestion process.Type: ApplicationFiled: December 26, 2006Publication date: May 10, 2007Applicant: ENVIRONMENTAL ENERGY & ENGINEERING CO.Inventor: Dennis Burke

Publication number: 20070038851Abstract: A method for programming secure data into nonvolatile memory in an IC is disclosed. The method includes steps for loading the secure data into temporary memory, temporarily disabling tester logging functions, and loading the secure data from temporary memory to the nonvolatile memory of the device. Further steps include verifying that the secure data is correctly loaded into the nonvolatile memory of the IC and implementing protection for the programmed secure data to prevent access subsequent to programming. Aspects of the invention include the selection or modification of patterns for programming secure data into nonvolatile memory. Temporary memory containing secure data and/or modified patterns is erased. The programming and protecting steps take place within a single instruction to the TOS so that the user does not regain access to the IC until the secure data is protected within the IC.Type: ApplicationFiled: August 12, 2005Publication date: February 15, 2007Inventors: Amit Babaria, Kevin Bittick, Dennis Burke, Chen-Yi Su
