Abstract: A location position system can include a plurality of beacons arranged a grid formation divided into a plurality of sub-grids. A mobile computing device can implement a location position application and can receive a radio signal from a particular beacon of the plurality of beacons. The radio signal can comprise a data component uniquely identifying the particular beacon, which can be used to identify a particular sub-grid of the plurality of sub-grids. An audio signal can be received from each of a set of sub-grid beacons associated with the particular sub-grid. Each audio signal can: (i) have a frequency in the frequency range of 16 kHz to 24 kHz and a transmission delay from a reference time, (ii) lack any additional identifying data, and (iii) be separately transmitted from the radio signal transmitted by the particular beacon. The mobile computing device can determine its position based on the received audio signals.

Abstract: Described herein are embodiments of methods and apparatuses for an augmented reality positioning system wherein an augmented reality device may directly (or indirectly through a separate smart device) connect with a constellation of beacons with ultra-wideband (UWB) modules to estimate a position and overall attitude for the augmented reality device and modify the perceived position of a virtual elements in space accordingly. The embodiments may include configurations for how various devices may connect and send data between one another. The embodiments may further include various constellation arrangements for beacons as well as embodiments of methods of trilateration that may be used to interpret data from various beacons.

Abstract: Conventional television audience measurements are made with diaries or by imaging the area in front of a television and trying to identify the people in the images watching television. Unfortunately, diaries are only accurate if the audience members record entries in them, and image-based techniques are intrusive. The present techniques address these problems by using a viewer's wearable device to measure a viewer's proximity to a television. The wearable device emits or receives low-power beacon signals; measurements of the signal strength are used to calculate the viewer's distance to the television. If the viewer is close enough to the television and the television is on, the viewer may be engaged with the content on the television. This system is simple, non-intrusive, and can used to measure engagement with each television in a multi-television household.

Abstract: Systems and methods are described for determining position of a receiver. The positioning system comprises a transmitter network including transmitters that broadcast positioning signals. The positioning system comprises a remote receiver that acquires and tracks the positioning signals and/or satellite signals. The satellite signals are signals of a satellite-based positioning system. A first mode of the remote receiver uses terminal-based positioning in which the remote receiver computes a position using the positioning signals and/or the satellite signals. The positioning system comprises a server coupled to the remote receiver. A second operating mode of the remote receiver comprises network-based positioning in which the server computes a position of the remote receiver from the positioning signals and/or satellite signals, where the remote receiver receives and transfers to the server the positioning signals and/or satellite signals.

An illustrative vehicle locating system includes a first Bluetooth Low Energy (BLE) beacon having a first location associated therewith and configured to receive a first radio frequency signal from a vehicle and coded with vehicle identification information. The first BLE beacon may be further configured to calculate a first proximity of the vehicle to the first BLE beacon and send to a server a first proximity signal indicative of the first proximity. A second BLE beacon has a second location associated therewith and is configured to receive a second radio frequency signal from the vehicle and coded with the vehicle identification information. The second BLE beacon may be further configured to calculate a second proximity of the vehicle to the second BLE beacon and send to the server a second proximity signal representative of the second proximity.

Abstract: A method is provided for transmitting data in a system for determining a location of at least one industrial truck comprising a mobile radio station and positioned in an area having a plurality of stationary radio stations. The method comprises transmitting a position-determining signal from the mobile radio station to the plurality of stationary radio stations. The position-determining signal is received and a position signal is transmitted from the plurality of stationary radio stations to the mobile radio station. Additional data is appended to at least one of the position-determining signal and the position signal and is evaluated. A current vehicle position is then determined from at least three received position signals.
