摘要： The physical position of a movable node in a network is determined by sending a broadcast message from the movable node repeated through a path comprising at least a first node, a second node, and a third node, wherein the first, second, and third nodes have known locations. The movable node receives the broadcast message from the first, second, and third nodes, and measures the time from sending the repeated broadcast message to the time the broadcast message is received from each of the first, second, and third nodes. The movable node determines the distance from the movable node to the first, second, and third network nodes by using at least a known turnaround time and known message propagation velocity, such that the position of the movable node is determined.

摘要： A method and system for position location of clients in wireless local area networks (WLANs). The position location technique utilizes time-of-flight (TOF) measurements of signals transmitted from a client to a number of wireless access points (APs) or vice versa to determine distances. Round-trip time (RTT) measurement protocols are used to estimate TOF and distances between the client at an unknown position and the WLAN APs. The method and system improves positioning accuracy by identifying and mitigating non-line-of sight (NLOS) errors such as multipaths. Trilateration algorithms are utilized in combination with median filtering of measurements to accurately estimate the position of the client.

摘要： In one embodiment of a positioning system, a transmit element is configured to transmit at least one electromagnetic pulse having a carrier signal frequency. An antenna array with a plurality of receive elements includes at least two receive elements separated by a spacing more than a half wavelength. Each of the at least two receive elements is configured to receive a return signal over a period of time. The return signal includes a return pulse from an object within a detection area of the system. The wavelength corresponds to the carrier signal frequency of the transmitted pulse. A detector is configured to process the return signal from one receive element and the other receive element so as to isolate the return pulse received at each of the at least two receive elements and thereby determine a position of the object in relation to the system.

摘要： A system and method for controlling access to a wireless networking system using RFID tags is provided. The security system and method uses RFID tags to determine the location of mobile computing device. The security system and method selectively allows access to the wireless networking system based on the determined location of the mobile computing device. For example, the security system and method will permit access to the wireless networking system if the mobile computing device is determined to be in an area of permitted access. Conversely, the security system and method will deny access to the wireless networking system if the mobile computing device is determined to be not within an area of permitted access. Thus, the system and method is able to effectively control access to the wireless networking system by only permitting access to mobile devices within designated areas.

摘要： A system and method is provided for locating objects using RFID tags. The system and method uses an RFID reader and a distance calculator to efficiently and accurately determine the location of objects that include an RFID tag. The RFID reader transmits a plurality of signals to the RFID tag, with the plurality of signals having different fundamental frequencies. In response, the RFID tag backscatter modulates the plurality of transmitted signals to create a plurality of backscatter-modulated signals. The RFID reader receives and demodulates the plurality of backscatter-modulated signals. The distance calculator determines the phase of the plurality of backscatter-modulated signals and determines a rate of change of the phase in the backscatter-modulated signals with respect to the rate of change in the fundamental frequency of the transmitted signals and uses this information to calculate the distance to the RFID tag.

摘要： The invention is a method and apparatus for determining the locations of a plurality of actual objects based on the output of a plurality of range sensors. A multiplicity of range measurements are obtained from a plurality of sensors, each sensor capable of providing a multiplicity of range measurements. The range measurements from the plurality of sensors are correlated with each other to generate a list of potential objects and to order that list of potential objects from highest to lowest likelihood of being an actual object. The order may be based upon a cumulative error of the individual sensor measurements upon which the potential object is based. The ordered list of potential objects is then pared down to a smaller list of actual objects by assuming that the potential object highest in the ordered list as an actual object, and then removing from the list all other lower-ordered potential objects that are based on any of the range measurements upon which the selected object is based. The process is repeated for the next highest potential object remaining on the list until all potential objects on the list have either been selected as an actual object or removed from the list.

摘要： A radar altimeter for determining altitude of an air vehicle comprises a transmitter for transmitting radar signals toward the ground. A first and a second antenna receive reflected radar signals from the ground. A signal processor is coupled to the first and the second antennas. The signal processor includes filter means for rejecting signals other than signals reflected from a selected ground swath. The signal processor determines the above ground level altitude of the air vehicle based on the radar signals output from the filter means. A phase ambiguity resolution means resolves phase ambiguities that arise due to multiple wavelength separation of the first and the second antenna. The signal processor also determines the horizontal position of the highest point in the selected ground swath. In a preferred embodiment, the phase ambiguity resolution means comprises a third antenna spaced closely to the first antenna such that there are no phase ambiguities between the reflected radar signals received by the third antenna and the first antenna.

摘要： The invention relates to a device for detecting the position and/or movement of several objects (O) and, optionally, of living things (S1, S2). The device comprises a position detection system provided with a sensor system which covers a spatially delimited area and which is equipped with at least one transmitter (10). Said transmitter is assigned to the object (O), is provided for detecting electromagnetic waves or sonar waves, and transmits signals to several receivers (E1, , E4) in order to detect at least the position of the objects. An evaluation unit (A) determines position and/or movement data of the objects (O) based on the signals transmitted by the position detection system. A computer (R1) calculates information from this data. A device is thus obtained which detects the position of a number of objects and/or living things with a sufficient degree of preciseness in order to evaluate this information in a suitable form.
