Abstract: A sensor is located within a vehicle that is able to determine pressure and location of an occupant or object. The sensor is able to take measurements during static conditions and situations where an object or occupant is moving due to the movement of, for example, a vehicle. The measurements taken during movement and during the static conditions and are used in order to enhance and refine the results of measurements that would be obtained if the measurements were taken alone.

Abstract: A sensing system adapted to determine changes in phase when a capacitive object enters into the phase detection zone created by a pair of transmitting conductors. One of the transmitting conductors has a receiving conductor located proximate to it and transmits a signal at a certain frequency. The other transmitting conductor transmits a signal that is phase shifted from the signal transmitted by the other transmitting conductor. Capacitive objects entering the space between the two transmitting conductors impacts the phase. Measurements of the change in phase are used to determine the position of an object between the two transmitting conductors.

Movement of the fabric or material with the transmitting and receiving antennas placed thereon are able to measure the changes in the signals received by the receiving antennas. Measurement of the changes are used to determine movement of and position of parts of the body within and/or distal to the fabric or material by determining localized pressure deformation to reconstruct volumetric changes.

Abstract: In an embodiment, a touch surface, such as a GUI is graphically divided into two or more input regions, and based on this division, input event paths from a single sensor can be integrated within an operating system to provide application developers with the ability to easily and effectively filter there-between. The graphical division allows an application developer to specify which elements of a given GUI take one path, versus another. In an embodiment, low-latency and high-latency event paths are provided; an algorithm takes into consideration input regions and, based on those regions, handles the low- and high-latency input event paths in a computer system, directing the appropriate inputs through the appropriate processing, and directing the output to the appropriate process or queue without creating constraints on the low-latency event processing due to the presence of higher-latency event paths for a given sensor.

Abstract: A close-range motion detector has at least one transmitter, at least one receiver, and at least one more transmitter or receiver. The transmitter(s) transmit, and the receiver(s) receive signals in one of the ultrasonic or mm-wave ranges. Multiple transmitters or receivers are spaced apart from one-another along a plane, and transmission of a signal takes place at a known time. Echos of the signal that bounce of a scatterer are received and digitized during a receive window, and the time-of-flight is determined using CAF. Time scaling may be determined as well, and may be determined using CAF. The determined time-of-flight is used to determine an X- Y-coordinate for the scatterer, and its motion (e.g., velocity) can be determined, which are output. In an embodiment, a such a close-range motion detector can be implemented on the side of a smart-watch, making a virtual writing surface on the back of a user's hand.

A finger may be operably connected to the reference strip, wherein the finger extends in the direction of the sliding strip, wherein movement of the reference strip with respect to the sliding strip is translated through the finger.

An object or body part's interaction with and reflection of millimeter wave signals are determined by the signals received by the receiving antennas. Signals having different frequencies are used to provide resolution and positioning of an object or body part in the space proximate to and/or relative to the sensor. Interpretation of millimeter wave radio signals reflected by objects in the environment, by the sensor, can then be used to generate outputs to devices.
