  • Patent number: 10026235
    Abstract: The disclosure relates to a method and system for detecting an event on a sports track. By applying one or more track segments across the width of the sports track and detecting passage of participants for the track segments, a comparison can be made between detected passage results and known passage results that may e.g. be available from a storage internal or external to the system. A deviation between the detection results and the known results that exceeds a particular deviation margin may be used as an immediate sign of an irregularity occurring during the sports event. The irregularity may e.g. relate to malfunctioning of one or more components of the time monitoring system or to deviating behavior by a participant to the sports event.

  • Publication number: 20130080049
    Abstract: A system and method for monitoring and tracking the position of a subject comprises, in an exemplary embodiment, a transponder configured for being co-located with the subject and a means for enabling communication between the transponder and a remote GPS-enabled receiver, such as a cell phone or the like, for selectively triangulating the position of the transponder. In the exemplary embodiment, the means for enabling such communication is software that is installed in and executed by the receiver. The software allows the receiver to triangulate the geographic position of the transponder by fixing a first reference point based on the location of the GPS-enabled receiver, fixing a second reference point based on the location of a network broadcast site through which the receiver and transponder communicate, and calculating the location of the transponder based on the angular position of the transponder relative to the network broadcast site.

  • Patent number: 8384584
    Abstract: Techniques are generally disclosed for communications between a locator device and a transponder device. The locator device may be located in a space based location such as on a surface of a remote celestial body, on a space craft or space station, on a satellite, or on a low earth orbit aircraft. The locator can encode an interrogation signal for receipt by one or more distant transponders. The transponder devices can receive the communications from the distant locator device and determine frequency, phase, cadence, and Doppler for encoding a reply transmission to the locator device. The encoding process estimates Doppler shift and adapts the reply transmission for a quantized reverse Doppler shifted frequency and cadence, which effectively pre-compensates for the Doppler shift that will be apparent to the locator due to the relative velocity. The locator can use the Doppler quantization scheme to reconstruct the actual relative velocity.

  • Patent number: 8350753
    Abstract: Systems and methods are provided for displaying information on a display device associated with an aircraft. A method comprises rendering a synthetic perspective view of terrain on the display device, wherein the synthetic perspective view of terrain is based on a set of terrain data corresponding to a region proximate the aircraft. The method further comprises obtaining location data for a first object, wherein the location data is based at least in part on a beacon signal associated with the first object, and rendering a graphical representation of the first object on the display device. The graphical representation of the first object overlies the synthetic perspective view of terrain and is positioned in accordance with the location data.

  • Patent number: 8350767
    Abstract: Described are a notch antenna and an array antenna based on a low profile stripline feed. The notch antenna includes a planar dielectric substrate having upper and lower surfaces. Each surface has a conductive layer with an opening therein. A notch antenna element is disposed on the conductive layer of the upper surface at the opening. A stripline embedded in the planar dielectric substrate extends under the notch antenna element. The stripline is adapted to couple an RF signal between the stripline and the notch antenna element. A conductive via is electrically coupled to the stripline and extends from the stripline to the opening in the conductive layer on the lower surface so that the RF signal is accessible at the lower surface.

  • Patent number: 8346437
    Abstract: When a lane-width-direction lateral position (X2obst+X0) of a vehicle (MM) reaches a predetermined control start position (60) being a lane-width-direction lateral position (X2obst+X0) serving as an approach prevention indicator for the vehicle (MM), a control start is determined and a yaw moment (Ms) toward the center of a vehicle traveling lane (200) is applied to the vehicle (MM) to control the vehicle (MM). Then, when the lane-width-direction lateral position (X2obst+X0) of the vehicle (MM) moves from the outside to the inside of the control start position (60), the determination of control start is suppressed for a predetermined period, compared to a period before the movement to the inside of the control start position (60).

  • Patent number: 8269664
    Abstract: The present invention pertains to a portable repeater device for use by friendly forces in a combat theater. The repeater device includes a sensor that receives an interrogator signal, coded or un-coded, from a friendly interrogator, such as an airborne attack or search and rescue vehicle, and a transmitter that transmits a coded or uncoded beacon at a covert wavelength outside the typical night-vision spectrum back to the interrogator in response. Because the transmission wavelength of the repeater signal is covert and outside typical night-vision capabilities, the system limits the ability of enemy forces to locate friendly forces employing such signaling beacons through typical night-vision equipment.

  • Patent number: RE45061
    Abstract: Communication between a remote locator and a transponder is used to determine the relative position of the transponder. The transponder and locator each include a transmitter and a receiver. The locator transmits an inquiry in the form of a relatively powerful cyclically encoded signal with repetitive elements, uniquely associated with a target transponder. Periodically, each transponder correlates its coded ID against a possible inquiry signal, determining frequency, phase and framing in the process. Upon a match, the transponder transmits a synthesized response coherent with the received signal. The locator integrates multiple cyclical response elements, allowing low-power transmissions from the transponder. The locator correlates the integrated response, determines round-trip Doppler shift, time-of-flight, and then computes the distance and angle to the transponder. The transponder can be wearable, bionically implanted, or attached to, or embedded in, some object.
