  • Publication number: 20080100497
    Abstract: A system and a method for position determination by impulse radio using a first transceiver having a first clock providing a first reference signal and a second transceiver placed spaced from the first transceiver. The system determines the position of the second transceiver. The second transceiver has a second clock that provides a second reference signal. A first sequence of pulses are transmitted from the first transceiver. The first sequence of pulses are then received at the second transceiver and the second transceiver is then synchronized with the first sequence of pulses. A second sequence of pulses are transmitted from the second transceiver. The first transceiver receives the second sequence of pulses and the first transceiver is synchronized with the second sequence of pulses. A delayed first reference signal is generated in response to the synchronization with the second sequence of pulses.

  • Publication number: 20080100498
    Abstract: A system and method for highly selective intrusion detection using a sparse array of time modulated ultra wideband (TM-UWB) radars. Two or more TM-UWB radars are arranged in a sparse array around the perimeter of a building. Each TM-UWB radar transmits ultra wideband pulses that illuminate the building and the surrounding area. Signal return data is processed to determine, among other things, whether an alarm condition has been triggered. High resolution radar images are formed that give an accurate picture of the inside of the building and the surrounding area. This image is used to detect motion in a highly selective manner and to track moving objects within the building and the surrounding area. Motion can be distinguished based on criteria appropriate to the environment in which the intrusion detection system operates.

  • Publication number: 20080075153
    Abstract: A method for specifying pulse characteristics applies codes having pre-defined characteristics to a layout. The layout can be sequentially subdivided into at least first and second components that have the same or different sizes. The method applies a first code having first pre-defined properties to the first component and a second code having second pre-defined properties to the second component. The pre-defined properties may relate to the auto-correlation property, the cross-correlation property, and spectral properties, as examples. The codes can be used to specify subcomponents within a frame, and characteristic values (range-based, or discrete) within the subcomponents.

  • Publication number: 20080063036
    Abstract: A system and method are provided that can detect any part of a multipath impulse radio signal. More specifically, the method compares a template pulse train and the multipath impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks onto any part of the multipath impulse radio signal including a direct path part and at least one multipath reflection part. The system may also perform a quick check, a synchronization check, and/or a command check of the multipath impulse radio signal.

  • Publication number: 20070222448
    Abstract: A system and method for probing a specimen to determine one or more components by utilizing a first signal to excite the specimen at a nuclear quadrupole resonant frequency and observing changes in a specimen property. One exemplary property may be dielectric constant. Another exemplary property may be magnetic permeability. In one embodiment, the first signal is unmodulated and a second signal is observed for the presence of modulation at the frequency of the first signal. Alternatively, the first signal may be modulated and the second signal may be observed for the presence of the modulation. A system is disclosed wherein the specimen is excited using the first frequency and a radar at the second frequency is used to observe changes in radar reflectivity of the specimen due to the excitation.

  • Publication number: 20070153873
    Abstract: A receiver for acquisition and lock of an impulse radio signal comprising an adjustable time base to output a sliding periodic timing signal having an adjustable repetition rate, and a decode timing modulator to output a decode signal in response to the periodic timing signal. The impulse radio signal is cross correlated with the decode signal to output a baseband signal. The receiver integrates T samples of the baseband signal and a threshold detector uses the integration results to detect channel coincidence. A receiver controller stops sliding the time base when channel coincidence is detected. A counter and extra count logic, coupled to the controller, are configured to increment or decrement the address counter by a one or more extra counts after each T pulses is reached in order to shift the PN code modulo for proper phase alignment of the periodic timing signal and the received impulse radio signal.

  • Publication number: 20070005969
    Abstract: A system for anonymous communication wherein a first party, subscriber, stores private contact address information with a server controlled by a trusted third party. The subscriber is associated with a token in the server database. The subscriber may publish the token with information of interest to a second party. The second party may then contact the server and provide the token. The server then enables communications between the first and second parties without either knowing the necessary contact information to independently make contact. The token may be published in any media and may be used to establish connection with email, voice, voice mail, e-chat rooms, or other communication media. In one embodiment, the third party may establish an account with the first party and may charge the first party for the communication service.

  • Publication number: 20060291537
    Abstract: Time is transferred from an ultra wideband (UWB) transmitter to UWB receiver by transmitting a signal structure having an associated timing reference point together with a time value for the timing reference point. The UWB receiver receives the timing signal structure by synchronizing a receiver time base to the signal structure, demodulating the time value information, and using the demodulated time value information to set a receiver clock value. Propagation delay information is used to adjust the receiver clock value by advancing the receiver clock value to account for the propagation delay. In one embodiment, propagation delay is determined from a known distance between the transmitter and receiver. In another embodiment, the transmitter and receiver are part of a two-way link wherein propagation delay is measured by round trip timing measurements.

  • Publication number: 20060152404
    Abstract: A method for processing radio frequency reflections is provided. The method applies an RF waveform to a transmission line that is a conductor used for providing a utility service. The method uses a RF waveform generator to transmit UltraWideband (UWB) RF waveforms through the conductors of a building. The RF waveforms are emitted at emission points that can be impedance discontinuities along the transmission line or impulse radios. The emitted RF waveforms reflect off of objects in the building and are received at reception points that can be impedance discontinuities or impulse radios. These reflections are processed to determine movement of objects within or near the building. Based on the reflections of the RF waveforms, the position of the objects within or near the building can be determined.

  • Publication number: 20060145853
    Abstract: A system and method for locating objects and/or receiving data associated with an object. An antenna or similar device that can intercept or modify RF energy is caused to vary its properties in accordance with a predefined time sequence pattern that is associated with the object. The antenna device is located proximate to the object to be located. To locate the object, a wide band radar device is utilized to transmit a probe signal and receive and analyze the return signal to identify the predefined pattern and determine the range to the antenna and thus determine the range to the associated object. The time sequence pattern is optionally modulated by a data stream to convey data associated with the object.
