The method includes: starting a vehicle image acquisition mode; receiving a plurality of radio frequency signals synchronously transmitted by at least two radio frequency identification transmitters distributed in a parking area in real time; determining a current position of a vehicle in the parking area according to the plurality of radio frequency signals as received; and displaying information identifying a vehicle virtual position to be parked in an image of the vehicle according to the current position of the vehicle in the parking area as determined and at least one available vehicle virtual position in the parking area.

Techniques and apparatuses are described that implement a smartphone-based radar system capable of detecting user gestures using coherent multi-look radar processing. Different approaches use a multi-look interferometer or a multi-look beamformer to coherently average multiple looks of a distributed target across two or more receive channels according to a window that spans one or more dimensions in time, range, or Doppler frequency. By coherently averaging the multiple looks, a radar system generates radar data with higher gain and less noise. This enables the radar system to achieve higher accuracies and be implemented within a variety of different devices. With these accuracies, the radar system can support a variety of different applications, including gesture recognition or presence detection.

Methods and apparatus for determining a location and an orientation of a smart device via wireless communication. The location and direction of the smart device may be used to generate a data query and/or submit information into a data storage, referencing a time, place and direction of the smart device.

An apparatus includes a directional scanner configured to receive signals from at least three RFID tags at a plurality of orientations of the directional scanner. The apparatus includes a pose estimator configured to estimate a pose of a device that includes or is coupled to the directional scanner based on orientation data indicating orientations of the directional scanner associated with determined peak signal strengths associated with the at least three RFID tags.

An apparatus obtains a set of radio data comprising signal strength related values for radio signals transmitted by a transmitter with an association of each signal strength related value with a representation of a geographical location. The apparatus applies a frequency transform to the obtained set of radio data to obtain transform coefficients, each transform coefficient comprising a transform index and an associated transform value. The apparatus selects a subset of transform indices having more significant transform values than the remaining transform indices and compresses the transform indices by encoding each transform index exploiting a probability of occurrence of an index value of a respective transform index. The same or another apparatus decodes the compressed transform indices again for use in position operations.

An exemplary radio-frequency (RF)-based navigation reference system uses one or more non-collocated and time-synchronized direction-finding transmitters to enable a client receiver to estimate its own 3-D position, velocity and time (PVT) using direction-finding (DF) waveforms obtained from said reference transmitters. At least one reference transmitter is sufficient for obtaining a 3-D PVT solution provided the client receiver is equipped with an accurate (low-drift) local clock such as a chip-scale atomic clock (CSAC). All other client receivers require at least two reference transmitters to estimate their 3-D PVT.
