摘要： A method for determining the distance to source of a passive intermodulation (PIM) product for a distributed base station is provided. The method includes generating a test signal; transmitting the test signal on a front haul communication link between a baseband unit and a remote radio head of the distributed base station; receiving the PIM product as a reflected signal at the remote radio head; multiplying the reflected signal by a conjugate of the test signal to create a sinewave; determining a frequency of the sinewave; and determining the distance to the source of the PIM based on the determined frequency of the sinewave.

摘要： A method of estimating a distance between a mobile unit and a vehicle includes providing a time of flight subsystem including circuitry incorporated in the mobile unit and circuitry incorporated in the vehicle, and generating a time of flight distance signal by periodically transmitting a time of flight signal between the mobile unit and the vehicle and measuring the time taken for transmission of the time of flight signal therebetween. A travel sensor is disposed at the mobile unit and generates a travel sensor signal. A value of a distance estimate signal is initialized based on the time of flight distance signal. A movement of the mobile unit is determined based on variance in the travel sensor signal. The initialized value of the initialized distance estimate signal is changed or increased or decreased based upon determination of movement of the mobile unit.

摘要： A method and apparatus for ranging finding of signal transmitting devices is provided. The method of signal reception is digitally based only and does not require receivers that are analog measurement devices. Ranging can be achieved using a single pulse emitting device operating in range spaced relation with a minimum of a single signal transmitter and a single digital receiver and processing circuitry. In general a plurality of transmitting pulsed emitters may be ranged and positioned virtually simultaneously in 3-dimensions (XYZ coordinates) using a configuration of a plurality of digital receivers arranged in any fixed 3-dimensional configuration. Applications may involve at least one single transmitter to receiver design to determine range, or at least one transmitted reflecting signal off from an object to determine range.

摘要： During a service period (SP) for a ranging measurement signal exchange between a first communication device and one or more second communication devices, the first communication device receives respective first null data packets (NDPs) from the one or more second communication devices, and transmits respective second NDPs to the one or more second communication devices. The first communication device transmits, during the SP, respective first ranging measurement feedback packets to the one or more second communication devices to allow each of the one or more second communication devices to determine a time-of-flight between the first communication device and the second communication device and/or receives, during the SP, respective second ranging measurement feedback packets from the one or more second communication devices to allow the first communication device to determine respective times-of-flight between the first communication device and the one or more second communication devices.

摘要： A method is provided for calculating a distance to a counterpart user equipment (UE) using device-to-device (D2D) communication, which is calculated by a UE in a wireless communication system. The UE receives a synchronization signal from a cluster head and receives a first discovery signal from the counterpart UE, and calculates a first difference value between a time of receiving the first discovery signal and a time of receiving the synchronization signal. The UE further receives, from the counterpart UE, information on a second difference value and calculates a first sum value of the first difference value and the second difference value. The UE receives, from the cluster head, information on a second sum value. The UE calculates a distance between the UE and the counterpart UE based on a difference between the second sum value and the first sum value.

摘要： Systems and methods are disclosed herein for monitoring and detecting a loss of synchronism in an electric motor, such as a synchronous motor. A monitoring system may compare a measured or provided electric power system frequency with a measured rotational frequency of the rotor of the electric motor. The rotational frequency of the rotor may be obtained from a shaft-mounted device. The monitoring system may determine a slip condition and/or a loss of synchronism of the electric motor.

摘要： A Real Time Locating System (RTLS) hygiene management and monitoring system for individuals and companies to manage and monitor the hygiene of their surroundings. For example, the system can be used in conjunction with a cleaning device and can include a locating module, a display module, and a cleanliness monitoring system. The locating module determines a location of the cleaning device in an area and to track movement of the cleaning device within the area. The display module includes a graphical layout of the area. The cleanliness monitoring system generates data representative of a path that the cleaning device has traversed in the area and at least one aspect of cleaning behavior of the device in the area. The display module displays the data representative of the path and the data representative of the at least one aspect of cleaning behavior, and one or both of the path and the at least one aspect of cleaning behavior is color-coded on the display module.
