    摘要： Systems and methods of determining a location of a mobile computing device associated with a real-time locating system are provided. For instance, a mobile computing device can determine a first location of the mobile computing device. The mobile computing device can then receive acoustic-contextual data that is correlated with the first location of the mobile computing device. The acoustic-contextual data can include data associated with one or more transmitting devices, and data associated with an environment proximate the one or more transmitting devices. The mobile computing device can receive one or more signals from at least one of the one or more transmitting devices, and can determine a more accurate second location of the mobile computing device based at least in part on the acoustic-contextual data and the one or more received signals.

    摘要： A control device (DC) equips a mobile unit (BM) comprising radio signal receivers (R11-R12) and acoustic signal receivers (R21-R22) and having to move to a target location defined relative to an object (V) emitting radio signals and acoustic signals. This device (DC) periodically determines the distance and direction separating a predefined location of the mobile unit (BM) from the target location by analyzing received radio signals, then commands suitable for moving the mobile unit (BM) to a predefined distance from the target location on the basis of this distance and direction, then periodically determines the distance and direction by analyzing received acoustic signals, then commands suitable for moving the mobile unit (BM) towards the target location on the basis of this distance and direction, until the predefined location is placed at the target location.

    摘要： The present disclosure relates to an acoustic position determination system that includes a mobile communication device and at least one base transmitter unit. The mobile communication device is configured to transmit and receive acoustic signals. Due to relative movements between the mobile communication device and the base transmitter unit, frequencies of the received signals shift due to Doppler effect. The mobile communication device is configured to compensate Doppler frequency shifts in the received acoustic signals prior to performing a deconvolution decoding process. The mobile communication device is further configured to compensate Doppler frequency shifts and perform deconvolution decoding process on acoustic signals received from multiple signal transmission paths.
