The cleaning behavior includes timing and movement of the device in the facility, and a cleanliness level of at least one area in the facility.

A storage medium-compatible communications unit, a phase detection unit, a parameter acquisition section and a location detection section are provided. The storage medium-compatible communications unit communicates with a storage medium by wireless using electromagnetic waves at a predetermined frequency. The phase detection unit detects phases of signals received from the storage medium. The parameter acquisition section acquires a distance detection parameter to be used in detecting a storage medium distance from a first position of an antenna to the storage medium. The first position is a position in a range of positions of the antenna from which the distance to the storage medium is shortest. The distance detection parameter is a value set in accordance with a positional relationship between the first position and a second position. The second position is a position of the antenna in the range of positions of the antenna that is different from the first position. The location detection section detects the storage medium distance, using a first phase detected by the phase detection unit at the first position, a second phase detected by the phase detection unit at the second position, and the distance detection parameter acquired by the parameter acquisition section. The location detection section identifies the first position at a time at which a trend of changes of phase detected by the phase detection unit in association with movement of the antenna reverses.

A communication unit, such as a radar unit (500) includes a plurality of cascaded millimetre wave, mmW, transceiver, TRx, circuit, each comprising at least one phase shift circuit (616) and each coupled to respective antennas; and a signal processor circuit (552) operably coupled to the plurality of cascaded mmW TRx circuits and configured to process transmit and receive signals of the plurality of cascaded mmW TRx circuits. The radar unit (500) further comprises: a first TRx circuit (320) of the plurality of cascaded mmW TRx circuits being configured to wirelessly transmit (360) a signal to a second TRx circuit (322) via a respective antenna; a localization processing circuit (580) operably coupled to at least one of the first TRx circuit (320) and second TRx circuit (322) and configured to wirelessly determine a distance relationship (350) between at least one antenna coupled to the first TRx circuit (320) and at least one antenna coupled to the second TRx circuit (322); and a phase control unit (602), operably coupled to the localization processing circuit (570) and configured to adjust at least one phase shifter (616) in response to the wirelessly determined distance relationship.

A radar system includes a transmitter for transmitting a radio frequency (RF) signal or a radar signal and a plurality of receivers. Each receiver receives a plurality of reflected signals created by a plurality of targets reflecting the RF signal or radar signal. The reflected signals include background noise and each of the receivers are separated by a predetermined distance. The radar system also includes a multiple input de-noiser configured to de-noise input signals from the plurality of receivers and to determine a time difference of arrival of the reflected signals between the plurality of receivers. A detection and angular resolution module is configured to determine an angular resolution between the plurality of targets using the time difference of arrival of the reflected signals between the plurality of receivers.

An autonomous system with no Customer Network Investment is described, wherein the system is configurable to operate on in a band in addition to the LTE band. Such system allows the definition of hybrid operations to accommodate the positioning reference signals (PRS) of LTE and already existing reference signals. The system can operate with PRS, with other reference signals such as cell-specific reference signals (CRS), or with both signal types. As such, the system provides the advantage of allowing network operator(s) to dynamically choose between modes of operation depending on circumstances, such as network throughput and compatibility. The system further enables information collected at a network device to be processed at a locate server without involving any processing at the network device.

Techniques are disclosed for determining an object's location by using a Reconfigurable Intelligent Surface (RIS) to aid in RF sensing. Radar techniques can be used in which one or more base stations act as a transmitter and a receiving device acts as a receiver in a bistatic or multi-static radar configuration where an RIS directs signals transmitted by the one or more base stations to the receiving device. By comparing the time a line-of-sight (LOS) signal (redirected to the receiving device by the RIS) is received by the receiving device with that of an echo signal (redirected to the receiving device by the RIS) from a reflection of an RF signal from the object, a position of the object can be determined. Depending on desired functionality, this position can be determined by the receiving device or by a location server or other network entity.

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.

A mobile computer may determine it is located in a vehicle or a conveyance based on a measured distance, satellite related positioning information, and a touch input.
