摘要： An acoustic location determination system is disclosed. The system includes one or more transmitting devices and one or more mobile devices. The transmitting device includes a first transducer configured to transmit first acoustic signals having a first frequency, and a second transducer configured to transmit second acoustic signals having a second frequency. The transmitting device further includes a beacon device configured to transmit beacon data via a short-range wireless communication technique. The transmitting device further includes one or more control devices configured to select the first or second acoustic signals based at least in part on one or more operating capabilities of one or more mobile units associated with the real-time locating system. The one or more control devices are further configured to cause transmission of the selected acoustic signals and the beacon data.

摘要： A tracked device may be used in an extended reality system in coordination with a tracking device. The tracked device may be ordinarily difficult to track, for example due to changing appearances or relatively small surface areas of unchanging features, as may be the case with an electronic device with a relatively large display surrounded by a thin physical outer boundary. In these cases, the tracked device may periodically present an image to the tracking device that the tracking device stores as an indication to permit tracking of a known, unchanging feature despite the image not being presented continuously on the display of the tracked device. The image may include a static image, designated tracking data overlaid on an image frame otherwise scheduled for presentation, or extracted image features from the image frame otherwise scheduled for presentation. Additional power saving methods and known marker generation methods are also described.

摘要： Systems, methods, and apparatus for detecting UAVs in an RF environment are disclosed. An apparatus is constructed and configured for network communication with at least one camera. The at least one camera captures images of the RF environment and transmits video data to the apparatus. The apparatus receives RF data and generates FFT data based on the RF data, identifies at least one signal based on a first derivative and a second derivative of the FFT data, measures a direction from which the at least one signal is transmitted, analyzes the video data. The apparatus then identifies at least one UAV to which the at least one signal is related based on the analyzed video data, the RF data, and the direction from which the at least one signal is transmitted, and controls the at least one camera based on the analyzed video data.

摘要： A method for indoor positioning, depending upon an embodiment of the present invention, comprises the steps of: setting node data including information regarding the location of a positioning sensor on a movement path of a moving object with respect to an indoor space; obtaining first positioning data capable of determining a first section in which the moving object is currently located, by using at least one of the node data, first sensing data obtained through a sensor unit provided in the moving object, and second sensing data obtained through the positioning sensor; determining whether the first positioning data satisfies a preset reference value for a boundary node defining the first section; and determining subsequent positioning data of the first positioning data on the basis of at least one of the node data, information indicating whether the reference value is satisfied, and information indicating whether the boundary node rotates.

摘要： Software for proximity positioning that performs the following operations: (i) receiving at least one parameter via an advertising channel of a first protocol, wherein the at least one parameter is encoded in an advertising packet of the first protocol, and wherein the first protocol supports a first proximity positioning technology; (ii) extracting the encoded at least one parameter from the advertising packet; and (iii) performing, by a second proximity positioning technology different from the first proximity positioning technology, a measurement of distance based, at least in part, on the at least one parameter.

摘要： According to one aspect of the presently disclosed subject there is provided a system implemented in a mobile carrier for determining a position of the mobile carrier by using a processing and memory circuitry (PMC) and a satellite communications on the move (SOTM) antenna system, being configured to maintain a communications link from a satellite communications (SATCOM) having a spatial position. The system is configured to obtain data indicative of the spatial position of the SATCOM, the estimated altitude of the mobile carrier and the direction of the antenna towards the SATCOM spatial position and to determine the position of the mobile carrier.

摘要： A method for locating wireless tags is described. A signal including a RoomID generated by a transceiver is received by a wireless tag. The RoomID identifies a room corresponding to the transceiver and the wireless tag receives the signal asynchronously without being synchronized with the transceiver. A tracking packet including the RoomID and an identifier of the wireless tag is broadcasted by the wireless tag. The tracking packet is received by an access point which provides the tracking packet to a localization system that determines a location of the wireless tag based on the RoomID.
