Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

Abstract: A method of determining a silhouette of a remote object is disclosed herein. The method can include directing an array of telescopes at a star to sense an intensity of EM radiation over time and transmit signals corresponding to the intensity. The signals can be received at a computing device. Each signal can be indicative of a portion of an intensity diffraction pattern generated by an occlusion of the star by an occluding object. The signals can be combined to form a two-dimensional, intensity diffraction pattern. Each point on the intensity diffraction pattern associated with a time, a position of each telescope in the array, and an intensity of the sensed EM radiation. A silhouette of the occluding object can be determined based on the intensity diffraction pattern. A system for performing the method is also disclosed herein.

Abstract: In the setting of chronic infection with a pathogen, the immune system must adapt to the ongoing presence of inflammatory responses driven by the pathogen in order to control the replication of the infecting agent at an acceptable level while limiting immune-mediated damage (immunopathology) (1). A complex interaction is required to accomplish this using a balance of immune related cytokines to stimulate and control the immune response. A particular formulation of reduced glutathione of high concentration in a liposome is proposed. In cooperation with the immune system, the liposomally formulated reduced glutathione according to the invention surprisingly achieves the balance between over-reduction of IL-10 and its necessary bodily function and signaling.

Abstract: Sparkless igniters for pilot services comprising hot surface igniter elements, and methods for operating these igniters without the use of flame rods or thermocouples. The electrical resistance of the hot surface igniter element is measured and used to control the operation of the igniters using a suitable burner management system. The measured electrical resistance may also be manipulated to yield a control parameter for use in the burner management system. The igniters are designed to prevent quenching of the hot surface elements by the fuel-air mixture. The igniters optionally permit easy swap out of hot surface igniter elements.

Abstract: An automatic playing card shuffler incorporating means for detecting marked cards. One or more light spectrum emitters or variable light spectrum illuminators transmit light at frequencies/wavelengths which is reflected off card backs through one or more spectrum filters causing invisible markings to become visible. A camera may capture images of the now visible markings. A camera and software collaborate to capture images and analyze the same for markings on the card backs such as smudges, nicks and scuffs and edge demarcations. The automatic playing card shufflers are configured to not only detect marked cards but to detect patterns relative to the card markings. The automatic card shufflers are communicatively linked with a casino management system and/or security system such that casino personnel may be alerted in real time to the discovery of marked cards.

Abstract: A remote controlled retractable leg iron device provides a restraint device which can be used by police or any other authority to maintain control of persons while in transport. The device is remote controlled so an operator can control the wearer from a distance. The cuffs are secured to the legs of the wearer and are attached to the housing unit by cables which coil around winch drums within the housing unit. The winch drums rotate freely in a normal operation mode so that the wearer can walk or move with little resistance. In an emergency mode, the device retracts the wire cables into the housing unit so that the wearer's legs are restrained tightly together—removing the lack of resistance and thus stopping the wearer's motion. The emergency mode is activated using the remote control.

Abstract: A low emissions 2-stroke natural gas fueled engine includes at least one cylinder with an exhaust port in communication with a silencer-catalytic converter unit. The unit has first and second volumes in communication with each other. The first volume damps spurious exhaust pressure excursions and removes particulates in the exhaust. The second volume houses an oxidation catalyst for treating exhaust to reduce exhaust emissions. The engine oil has at most 10 ppm zinc content to reduce metal poisons contained in the exhaust prior to contact with the oxidation catalyst. The engine oil preferably has a very low ash content to minimize sulfur combustion components in the exhaust to reduce masking of the oxidation catalyst. The first volume preferably has a pressure relief valve set to relieve at a pressure greater than the maximum normal operating pressure of the engine to avoid excessive pressure excursions of the engine exhaust from damaging the oxidation catalyst.
