  • Patent number: 8112504
    Abstract: An audio program and message distribution system in which a host system organizes and transmits program segments to client subscriber locations. The host organizes the program segments by subject matter and creates scheduled programming in accordance with preferences associated with each subscriber. Program segments are associated with descriptive subject matter segments, and the subject matter segments may be used to generate both text and audio cataloging presentations to enable the user to more easily identify and select desirable programming. A playback unit at the subscriber location reproduces the program segments received from the host and includes mechanisms for interactively navigating among the program segments. A usage log is compiled to record the subscriber's use of the provided program materials, to return data to the host for billing, to adaptively modify the subscriber's preferences based on actual usage, and to send subscriber-generated comments and requests to the host for processing.

  • Patent number: 7924160
    Abstract: A system for tracking the position of multiple objects in three dimensional space by transmitting radar interrogation signals having predetermined wave shapes to surface acoustic wave transducers attached to each object. Each transducer includes a unique electrically conductive pattern on one surface of a piezoelectric substrate for selectively responding to the predetermined wave shape of one of the interrogation signals for inducing a surface acoustic wave in the substrate and for thereafter transforming the surface acoustic wave into an electromagnetic response signal having detectable properties that uniquely identify said transducer. The location of each transducer is estimated by measuring the time-of-flight or angle-of-arrival of the radar signals at several measurement stations and producing a position estimate by triangulation.

  • Patent number: 7755765
    Abstract: An inertial sensor consisting of an electrodynamic trap for suspending one or more charged particles and a readout device for measuring variations in the position or motion of the particles when the trap is subjected to acceleration forces. Particle may be measured by optical interferometry, optical leverage, resonant electric field absorption, or by producing an image of the particle motion and processing the image data to obtain values representing the acceleration forces on the trap in one to six degrees of freedom. The electrodynamic trap employs electrodes to which a time-varying potential are applied to produce a quadupole field that constrains the charged particles to a specific location between said electrodes by a substantially linear, tunable restoring force.

  • Patent number: 7432893
    Abstract: A touch panel in which two or more light sensors emit light into a transparent panel at an angle to sustain transmission through the panel by total internal reflection. The transmitted light is detected at an array of light detection positions around the periphery of the panel opposite to each light source. When an object contact the surface of the panel, light transmitted along the pathway from a given source past the contact point to one of the detection points is attenuated by the frustrated total internal reflection (FTIR) effect. Each contact causes two or more intersecting light beams having known end points to be attenuated, enabling a connected processor to determine the position and size of the contact area.
