Abstract: In a position detection system that has a plurality of transmitters/receivers placed at least three positions: processing is executed to measure distances among the plurality of transmitters/receivers, each distance being measured a plurality of times, and obtain a minimum value for each distance; processing is executed to obtain an angle between each two adjacent straight lines, each of which is one of straight lines that mutually connect the plurality of transmitters/receivers, by using minimum values, each of which is the minimum value for each distance; and if the absolute value of the difference between 180 degrees and the sum of angles, each of which is the angle between each two adjacent straight lines, inside a triangle formed by straight lines that interconnect three of the plurality of transmitters/receivers is smaller than a predetermined value, processing is executed to take the minimum values as the true values of the distances.

Abstract: A method and apparatus for determining a distance between a first radar system disposed on a vehicle and a second radar system disposed on the vehicle. A target reflector is moved along a track to a location along a perpendicular bisector of a baseline connecting the first radar system and the second radar system. A direct range measurement is obtained for at least one of the first radar system and the second radar system, and a bistatic range measurement is obtained between the first radar system and the second radar system. A processor determines the distance between the first radar system and the second radar system using the direct range measurement, the bistatic range measurement and a radial length of the target reflector.

Abstract: A passive radar comprises a reception antenna for a signal transmitted by a non-cooperative transmitter, the received signal comprising a static contribution related to propagation of the signal transmitted through a multi-path propagation channel and a dynamic contribution related to propagation of echoes of the transmitted signal from a moving target. The passive radar also comprises a reception chain that includes an analogue-digital converter capable of outputting a digitised signal, a moving target detection unit, a digitised signal processing unit configured to determine an estimation of the static contribution during a calibration phase of the passive radar, a transmission chain that can output an analogue signal representative of the estimation of the static contribution, and a directional coupler configured to output the signal received during the calibration phase of the passive radar to the reception chain.

Abstract: A method for operating a domestic appliance includes the steps of: receiving, by means of the domestic appliance, a radio signal from at least one radio transmission source; and determining, by means of the domestic appliance, information on surroundings of the domestic appliance by evaluating a temporal progression of an evaluation signal based on the radio signal and influenced by the surroundings of the domestic appliance. The radio signal is intended for transmission within a local radio network and/or complies with the IEEE 802.11 standard, the IEEE 802.154 standard, or the Bluetooth standard.

Abstract: We describe a sensor system for measuring relative distance between sensors of the system, the sensor system comprising at least two sensors, wherein each said sensor comprises an RF transceiver coupled to a microprocessor and stored program code for controlling the microprocessor, wherein said stored program code comprises code to: send, using said RF transceiver a group of one or more data bits from the sensor to a second sensor; receive, using said RF transceiver, an acknowledgement of reception of said group of data bits from said second sensor; determine a time difference between said sending and said receiving; compensate said time difference from a processing delay by the microprocessor of said second sensor between the second sensor receiving said group of data bits and sending said acknowledgement, to determine timing data reprinting distance to said second sensor.

Abstract: Various aspects of the disclosure relate to millimeter wave ranging with six degrees of freedom. For example, a multi-gigabyte link (e.g., an IEEE 802.11ad link or an 802.11ay link) and RF/Antenna diversity modules can be used to conduct round trip time (RTT) distance measurements between an anchor point and a station. Relative location information (e.g., degrees of freedom) between the wireless devices can then be determined based on the distance measurements.

Abstract: An apparatus, method, and computer program product are provided to filter and modify option data objects and weighted values associated with option data objects through the application of specific rule sets based on the relative density of option data objects within a particularized area. In some example implementations, option data objects and related parameters are parsed to identify locations associated with the option data object and a weighted value, such as a weighted value generated by a predictive model. Based at least in part on the location associated with the option data object, a determined location of a user of a mobile device, and location-specific distance criteria, the weighted value associated with the option data object may be modified to reflect distance-related option election probabilities.

Abstract: Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.

Abstract: Methods, systems, and products determine electromagnetic reflective characteristics of ambient environments. A wireless communications device sends a cellular impulse and receives reflections of the cellular impulse. The cellular impulse and the reflections of the cellular impulse may be compared to determine the electromagnetic reflective characteristics of an ambient environment.
