20090045997METHOD AND SYSTEM FOR COMMUNICATING USING PULSED RADAR SIGNAL DATA LINKS - A method and system for communicating using pulsed radar signal data links is disclosed. The method comprises encoding downlink data with a signature sequence as a secondary function onto a continuous wave pulse signal having a primary function at a master device. The data-encoded pulse signal from the master device is interpreted at one or more slave devices configured to receive the pulse signal within a first communications bandwidth of the primary and secondary functions. The master device synchronizes returning communication transmissions from each of the one or more slave devices for the secondary function within a prescribed return interval of the primary function.02-19-2009
20120119936SYSTEM AND METHOD FOR TRANSMITTING VEHICLE INFORMATION TO AN OCCUPANT COMMUNICATION DEVICE - In at least one embodiment, an apparatus for transmitting vehicle information to an occupant communication device (OCD) is provided. The system comprises a communication module positioned within the vehicle. The communication device is configured to receive a transmission status signal indicative of a transmission mode for the vehicle. The communication device is further configured to transmit the transmission status signal over a wireless protocol to the OCD such that the OCD is disabled from being controlled by switches positioned thereon if the transmission mode enables movement of the vehicle.05-17-2012

20110057827Holographic Imaging Based on Time-Domain Data of Natural-Fiber-Containing Materials - Methods and apparatuses for imaging material properties in natural-fiber-containing materials can utilize time-domain data. In particular, images can be constructed that provide quantified measures of localized moisture content. For example, one or more antennas and at least one transceiver can be configured to collect time-domain data from radiation interacting with the natural-fiber-containing materials. The antennas and the transceivers are configured to transmit and receive electromagnetic radiation at one or more frequencies, which are between 50 MHz and 1 THz, according to a time-domain impulse function. A computing device is configured to transform the time-domain data to frequency-domain data, to apply a synthetic imaging algorithm for constructing a three-dimensional image of the natural-fiber-containing materials, and to provide a quantified measure of localized moisture content based on a pre-determined correlation of moisture content to frequency-domain data.03-10-2011
