Abstract: A compound sensor system includes a first sensor, a second sensor, a memory that stores a module, and a processor coupled to the first sensor, the second sensor, and the memory. The first sensor is configured to detect a parameter that indicates a likelihood of having a user enter or leave a target area, and, in response, send a first command signal to the processor. The processor is configured to receive the first command signal from the first sensor and send a second command signal to the second sensor based on receiving the first command signal. The second sensor is configured to operate at a sleep mode and switch to an active mode upon receiving the second command signal, and during the active mode the second sensor is configured to determine if the user enters or leaves the target area.

Abstract: Disclosed are methods and systems for determining distance between two or more mobile devices utilizing a sound emitted from each device such as a chirp. Each device may determine or receive an indication of a time reference for each instance the device emits or detects a chirp. Utilizing the time reference data, the distance between the two or more devices may be determined assuming the sound travels at a constant speed of 340.29 m/s. Techniques for disambiguating orientation of the devices relative to one another rare also disclosed.

Abstract: A sound collecting unit (10) mounted on a vehicle is configured to collect sounds, a frequency resolution unit (21c) is configured to perform frequency analysis on the collected sound information, and when an object around the vehicle is detected based on a frequency characteristic of the sound information, a traveling sound detecting unit (21d) is configured to perform object detection such that object detection using a predetermined frequency band when a sound pressure of the predetermined frequency band is high in a frequency characteristic of a sound reproduced from a reproduction unit (11) mounted on the vehicle is more suppressed than object detection using a predetermined frequency band when a sound pressure of the predetermined frequency band is low in the frequency characteristic of the sound reproduced from a reproduction unit (11).

Abstract: The latching device for a rotationally or translationally movable operating element is provided with a resiliently mounted latching projection and with a latching guideway which is in sliding contact with the latching projection and which has a plurality of latching depressions with latching elevations arranged between them. The latching depressions and the latching elevations form a substantially corrugated latching path along which the latching projection slides during a relative movement between latching guideway and latching projection. The latching projection has a surface which contacts the latching path along at least one contact line running substantially transversely to the longitudinal extent of the latching path. When sliding along the latching path, the latching projection experiences an upward and downward movement with periodic change of the orientation of its contact line with respect to the latching guideway.

Abstract: Satellite data is used to determine water depth by accounting for the changing turbidity of the water over time and without requiring calibration using SONAR measurements. Radiance values at multiple wavelengths sensed at both a first time and a second time are stored in a database. Modeled reflectance values are calculated for a defined surface area on the water based on an assumed depth, assumed water constituents and assumed bottom cover. A plurality of differences between the modeled reflectance values and the reflectances sensed at the two times are calculated. A bathymetry application module minimizes the sum of the differences between the modeled and sensed subsurface reflectances by varying the assumed depth, bottom cover and water constituents. The differences are weighted based on wavelength before being summed. The depth that results in the minimized sum of the differences is the estimated depth, which is displayed on a graphical user interface.

Abstract: A system and method for detection of multipath and transmit level adaptation thereto in ultrasonic locationing of a mobile device within an environment includes providing fixed ultrasonic emitters for transmitting ultrasonic bursts at predetermined times. A communication device measuring at least a direct signal of each ultrasonic burst and detecting multipath of each ultrasonic burst by comparing an amplitude of the direct signal with other signals related to the ultrasonic burst. If multipath is detected a controller increasing a transmit power level of the ultrasonic burst to insure the direct signal reliably remains above the detection threshold. If multipath is not detected reduce a transmit power level to the point detection is just possible. Results from non-multipath conditions are more heavily weighted when determining position as they are typically more accurate.

Abstract: Disclosed is a system and method for calibrating BLE signal strengths to high-accuracy/precise distances. The present disclosure involves auto-calibrating BLE-based tracking systems, such as, for example, those used indoors using acoustic signals. The present disclosure enables BLE-based distance estimation to be accurate to decimeters and centimeters. The disclosed systems and methods utilize signals communicated to and from roaming devices in order to determine the distance(s) between the roaming device and installed BLE units. A signal-strength to distance map can then be constructed for reuse on any device with a Bluetooth component.
