<link>http://www.freepatentsonline.com/20080094275.html</link>
<description><![CDATA[A system for tracking an object in space for position, comprises a transponder device connectable to the object. The transponder device has one or several transponder aerial(s) and a transponder circuit connected to the transponder aerial for receiving an RF signal through the transponder aerial. The transponder device adds a known delay to the RF signal thereby producing an RF response for transmitting through the transponder aerial. A transmitter is connected to a first aerial for transmitting the RF signal through a first aerial. A receiver is connected to the first, a second and third aerials for receiving the RF response of the transponder device therethrough. A position calculator is associated to the transmitter and the receiver for calculating a position of the object as a function of the known delay and the time period between the emission of the RF signal and the reception of the RF response from the first, second and third aerials. A method is also provided.]]></description>

<title><![CDATA[Radar]]></title>
<link>http://www.freepatentsonline.com/20080094274.html</link>
<description><![CDATA[A radar for detecting a target wherein a standard deviation of the amplitude of a beat signal from a transmission signal and a reception signal is determined for a predetermined period. A threshold is determined by adding a predetermined value to the standard deviation or by multiplying the standard deviation by a predetermined coefficient. The presence or absence of interference on the beat signal is detected according to the presence or the absence of an amplitude greater than the threshold. For example, an amplitude exceeding the standard deviation×2 is considered a spike noise (SPN), i.e., as “presence of interference”. The threshold used for detecting peaks appearing on a frequency spectrum is then increased. This allows detection of the presence or the absence of a spike noise superposed on the beat signal to be performed more certainly, thereby enabling processing according to the presence or the absence of interference.]]></description>

<title><![CDATA[Excess Delay Estimation Using Total Received Power]]></title>
<link>http://www.freepatentsonline.com/20080094277.html</link>
<description><![CDATA[To determine the position of a mobile device located within a coverage area of a base station, the time of arrival (TOA) of the CDMA signal received by the mobile device from the base station is reduced in proportion to the received power of the CDMA signal. The mobile device uses the reduced TOA of the CDMA signals together with the received GPS signals to detect its position. Alternatively, the mobile device transmits the TOA and power measurements of the received CDMA signals to a position determination entity (PDE). The PDE biases the TOA to estimate the position of the mobile device and transmits assistance data to the mobile device, thereby enabling the mobile device to receive GPS signals. The received GPS signals alone, or in combination with the biased TOA are then used to recompute the position of the mobile device.]]></description>

<title><![CDATA[METHOD AND SYSTEM FOR DISTANCE ESTIMATION]]></title>
<link>http://www.freepatentsonline.com/20080094278.html</link>
<description><![CDATA[A method of estimating distance with reference to a target location and radius is disclosed. The method includes transforming the target location and radius into a degree offset threshold for avoiding unnecessary distance calculation, receiving a set of global positioning coordinates that define a location of a portable global positioning system (GPS) device, and comparing the set of global positioning coordinates to the degree offset threshold. In response to the set of global positioning coordinates meeting the degree offset threshold, the method further includes calculating a preliminary distance between the global positioning coordinates and the target location.]]></description>

<title><![CDATA[Systems and methods for detecting variations in composite structures]]></title>
<link>http://www.freepatentsonline.com/20080094273.html</link>
<description><![CDATA[A system and method to detect changes in composite structures using RF signal pattern data interpretation. An RF signal is transmitted from a composite material manufactured structure and a plurality of sensors are employed to measure the RF signal. The measured RF signal is compared to a stored baseline RF signal for the particular structure. Deviations in the measured RF pattern for the structure, or for a structurally-similar composite structure, are automatically analyzed to detect non-visually-detectable defects or other changes in the composite structure. A baseline RF signature is developed for a structure by transmitting a reference RF signal from the composite structure. RF signals are detected by a variety of methods, and the detected signals are compiled and translated into reference and/or test RF signal patterns for the structure.]]></description>

<title><![CDATA[ALTBOC RECEIVER]]></title>
<link>http://www.freepatentsonline.com/20080094280.html</link>
<description><![CDATA[An AltBoc receiver accumulates power measurements over code chip ranges that are associated with time slots that span the code chips. The receiver combines a received signal with code and carrier phase offsets that correspond to the time slots to produce the power measurements, with the code phase offsets determined from compressed signals representing one or a combination of the codes in the AltBoc signal. The receiver recovers navigation data from the data channels of the received signal and combines the recovered data with the corresponding locally generated PRN codes to produce a locally generated 4 code signal that is then used track the full 8PSK AltBoc received signal. The receiver rotates and shifts the phase of the received signal in order to line up the subcarrier splitting code zero crossings. The pulse shape of this rotated and shifted signal is measured. The resulting sharp edges of the recovered subcarrier are used to control the code phase of the receiver.]]></description>
