Methods, apparatus and systems for wireless proximity sensing are described. In one example, a described system comprises: a transmitter configured for transmitting a first wireless signal through a wireless multipath channel of a venue; a receiver configured for receiving a second wireless signal through the wireless multipath channel; and a processor. The second wireless signal differs from the first wireless signal due to the wireless multipath channel that is impacted by a movement of an object in the venue. The processor is configured for: obtaining a time series of channel information (TSCI) of the wireless multipath channel based on the second wireless signal, wherein each channel information (CI) of the TSCI comprises a plurality of CI components, each of which is associated with an index; computing an inter-component statistics based on the plurality of CI components; computing, based on the inter-component statistics, a proximity information of the object with respect to a reference location in the venue; and performing a task based on the proximity information of the object.

The present invention relates to visible components with a functional coating in the interior and exterior of motor vehicles and a method for the production thereof.

A mobile-platform imaging device uses compression of the target region to generate an image of an object. A tactile sensor has an optical waveguide with a flexible, transparent first layer. Light is directed into the waveguide. Light is scattered out of the first layer when the first layer is deformed. The first layer is deformed by the tactile sensor being pressed against the object. A force sensor detects a force pressing the tactile sensor against the object and outputs corresponding force information. A first communication unit receives the force information from the force sensor. A receptacle holds a mobile device with a second communication unit and an imager that can generate image information using light scattered out of the first layer. The first communication unit communicates with the second communication unit and the mobile device communicates with an external network.

A method for measuring a distance to a target in a multi-user environment, comprising: irradiating the environment by a series of light pulses, wherein this series of light pulses is emitted by a battery of at least two or a single light source device emitting on at least two different wavelengths, the light pulses being emitted at a determined repetition rate and with a determined randomly selected wavelength; collecting pulses reflected or scattered from the environment to at least one detector equipped with a wavelength filter whose pass band corresponds to the selected emitted wavelength; assigning a timestamp at the detection of a pulse by at least one chronometer connected to the detector, said timestamps corresponding to the time of arrival (TOA); determining the statistical distribution of said time of arrivals; determining the distance to the target from said statistical distribution.

The master scanning laser and the slave scanning laser are connected to each other via a communication network adapted to support a network protocol wherein messages are sent according to said network protocol, including a synchronization message for clock synchronization of said master scanning laser and said slave scanning laser.

Realization of a sensing device that does not suspend the sensing function. A sensing device having a sensor for sensing the external environment through a window frame portion provided at a predetermined position of a main body of a vehicle or the like, and a plurality of protective members for protecting the sensor are provided. At least one of the protective members is arranged at the window frame portion, and the sensor is arranged inside the protective member at the window frame portion to be protected, and the protective member at the window frame portion, is evacuated from the window frame portion when it becomes dirty or periodically, and instead, another protective member is moved to be arranged at the window frame portion and the evacuated protective member is washed by the washing device so that it can be used again.

Described examples include a receiver having a beam splitter arranged to receive reflected light from a scene illuminated by a transmitted light signal, the beam splitter structured to provide at least two copies of the reflected light including at least two regions having sub-regions, wherein the sub-regions are not adjacent to each other. The receiver also includes a first sensor array arranged to receive one region of the reflected light and provide an output representative of that region of the reflected light. The receiver also includes a second sensor array arranged to receive the other region of the reflected light and provide a second output representative of the second region of the reflected light. The receiver also includes a combiner arranged to receive the outputs of the sensor arrays to provide a combined representation of the reflected light.

Disclosed herein is a system for detecting rotational speed and early failures of an electronic device. The system includes a rotating disk affixed to a rotating shaft of the electronic device. The rotating disk has projections extending from its periphery. A time of flight ranging system determines distance to the projections extending from the rotating disk. Processing circuitry determines a rotational speed of the rotating shaft from the determined distances to the projections extending from the rotating disk, and detects whether the electronic device is undergoing an early failure from the determined distances to the projections extending from the rotating disk. Rotational speed is determined from the time between successive peaks in the determined distances, and early failures (for example, due to wobble of the shaft) are determined where the peaks vary unexpectedly in magnitude.

A method and apparatus of a first network entity in a wireless communication system is provide. The method and apparatus comprises: identifying at least one set of bit strings to generate a ranging scrambled timestamp sequence (STS); identifying at least one initialization vector (IV) field corresponding to the at least one set of bit strings, wherein the at least one IV field comprises a 4-octet string; generating a ranging STS key and IV information element (RSKI IE) that includes the at least one IV field to convey and align a seed that is used to generate the ranging STS; and transmitting, to a second network entity, the generated RSKI IE for updating the ranging STS of the second network entity.

A system for radio-frequency imaging of a structural environment is disclosed, including radio devices configured to transmit radio signals and a radio imaging device configured to receive the radio signals transmitted by the radio devices. The radio signals received at some times are scattered, reflected, or attenuated by an object collocated with an active localization device. The radio signals received at other times are scattered, reflected, or attenuated by the object not collocated with the active localization device. The system can obtain an indication of a location of the active localization device and, based on the radio signals received at the times the object is collocated with the active localization device, generate a radio signature of the object associated with the location. The system can then compute a score indicative of a likelihood that the object is at the location when it is not collocated with the active localization device.
