An apparatus and a method for locating a mobile terminal, in particular a mobile radio terminal for a cellular mobile radio network by way of an apparatus of a motor vehicle. The mobile terminal sets up a connection to at least one first receiver, while the mobile terminal does not set up a connection to the at least one further one of the receivers at least for this locating operation. Both the at least one first receiver and at least one of the further ones of the receivers each determine a field strength of at least one radio signal transmitted by the mobile terminal or a first receiver. The field strengths thus determined are used to locate to locate the mobile terminal.

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.

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.

One variation of a method includes: defining a first capacitance gradient of capacitance thresholds spanning a capacitive touch sensor; defining a first pressure gradient of pressure thresholds spanning a pressure sensor; reading a capacitance value from the capacitive touch sensor proximal a first location; detecting presence of a first input at the first location in response to the capacitance value exceeding a capacitance threshold assigned to the first location; reading a pressure value from the pressure sensor proximal the first location; detecting presence of a second input proximal the first location in response to the pressure value exceeding a pressure threshold; in response to detecting the first input and detecting the second input: merging the first input and the second input into a confirmed touch input; and generating a first touch image representing the first location and the pressure value of the confirmed touch input.

Methods and systems related to an antenna orientation are disclosed herein. In one specific embodiments, a system comprises a positioning device configured to generate a positioning signal, a control object, and an object antenna configured to receive the positioning signal. The object antenna has a first polarization axis and is located on the control object. The system also comprises a positioning device antenna configured to transmit the positioning signal. The positioning device antenna has a second polarization axis and is located on the positioning device. The first polarization axis and the second polarization axis are offset from parallel by greater than thirty degrees when the positioning device and control object are in a standard operating mode. The first polarization axis and the second polarization axis are offset from perpendicular by greater than thirty degrees when the positioning device and control object are in a standard operating mode.

A method for monitoring depth of a cave front in a cave-type mine. The method includes: providing a stationary reader device and mobile marker devices, each of the marker devices adapted to (i) emit an electromagnetic signal, (ii) detect strength of the signal emitted by another of the marker devices, and (iii) wirelessly transmit information related to the detected signal via the other marker devices to the stationary reader device; drilling a hole into a rock region of a mine, installing the mobile marker devices at sequential known depths within the hole; monitoring the reader device to detect a decrease in the strength of a signal emitted by a first marker device by a second marker device; and in response to a decrease being detected by the second marker device, inferring the depth of the cave front to be between the known depths of the first and second marker devices.
