A pressure sensor is disclosed which includes a transmit electrode adapted to be operatively connected to a signal generator, a receive electrode adapted to be operatively connected to a signal receiver and signal processor, and a variably resistive conductive deformable element. The transmit electrode, the receive electrode and the variably resistive conductive deformable element being positioned in proximity to each other such that a pressure event proximate to the variably resistive conductive deformable element causes a change in coupling between the transmit electrode and the receive electrode, and a signal transmit on the transmit electrode as received on the receive electrode is changed in at least one of magnitude or phase in relation to and as a result of a pressure event.

Apparatus and method for sensing pressure

A sensor for use with vehicular components. The sensors may comprise transmitting and receiving antennas that can be interleaved or placed within the various materials throughout the vehicle so that interaction with the materials will provide information related to the use. Sensors may also infuse signal into an occupant within the vehicle via the material which can provide enhanced interactions with various vehicle features and components.

Vehicular components comprising sensors

A sensor system comprises a plurality of receiving antennas. Another antenna functions as an isolating antenna that assists in preventing a signal received at some of the receiving antennas from being interfered with by the other receiving antennas. The isolating antenna may be operably connected to a ground or the source of signal that is also infused into a user.

Matrix sensor with receive isolation

An array of antennas form a sensor device. Some of the array of antennas function as receivers and some of the array of antennas function as transmitters. Each of the transmitters may transmit a unique frequency orthogonal signal that may be received at the receivers. Measurements of the received signal are then used to determine activity within field lines.

Matrix sensors

A plurality of sensors for application to a steering wheel or other generally toroidal objects is disclosed. In an embodiment, the sensor comprises interleaving transmit and receive conductors. In an embodiment, the sensor comprises crossing transmit and receive conductors. In an embodiment, sensor conductors are first provided on a flat substrate, which sensors placed on the flat substrate in a configuration that will permit expansion application of the substrate to the steering wheel.

Toroidal sensor

A touch sensor is provided having a sensing area comprising at least one drive conductor and one sense conductor. The drive conductor and the sense conductor are each disposed on the substrate such that, for any two given points on the drive conductor within the sensing area, the nearest point to each on the sense conductor within the sensing area is a different distance away. Drive and sense circuitry are used to measure a touch delta resulting from a given touch on the sensor. For a given touch, the measured touch delta will vary with the location of that touch along the length of the conductors. A third conductor may be added that has the same relationship with a middle (drive or sense) conductor. Repeating use of the two or three conductor patterns can be used to cover wider areas.

Single sided capacitive sensor

A controller for sensing deformation including a sensor structure having a deformable conductor and another conductor (which may also be deformable). The deformable conductor may be made out of a flexible non-fluid material (e.g., rubber) or a conductive fluid. The deformable conductor may be deformed by the deformation of the sensor structure or by other forces. The sensor comprises circuitry to drive and sense signals on interacting pairs of conductors (the deformable conductor or the other conductor can act as the drive side, or as the sense side). Sense signals are processed to analyze deformation of the deformable conductor, and deformation of the sensor structure. Where the sensor is deployed proximate to human skin, deformation and changes in deformation may be used to correlate or infer a body position, movement or pose.

Flexible deformation sensor

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.

Movement enhanced detection

A sensor system comprises a plurality of receiving antennas. Another plurality of antennas functions as transmitting antennas. The antennas may be placed on a deformable substrate. The deformable substrate may be part of a band that is worn proximate to a hand.

An array of antennas form a sensor device. Some of the array of antennas function as receivers and some of the array of antennas function as transmitters. Each of the transmitters may transmit a unique frequency orthogonal signal that may be received at the receivers. Measurements of the received signal are then used to determine a hand motion.

Matrix sensors for use with a controller

A sensor for sensing contact with an outside object is disclosed. A sensor stackup has top surface, having an outer skin adapted for contact with the outside object. The stackup also including, a deformable layer below top surface in the stackup, the deformable layer including patches made from conductive or high dielectric material. The stackup further including a capacitive sensor layer below the deformable layer, the capacitive sensor layer comprising conductors that are insulated from the patches. Each of the patches is displaceable with respect to the capacitive sensor layer in response contact with the outside object. The stackup also includes a backing layer below the capacitive sensor layer in the stackup. The sensor further includes capacitive sensor circuitry operatively connected to the capacitive sensor layer, the capacitive sensor circuitry configured to detect changes in capacitive coupling between the conductors of the capacitive sensor layer resulting from displacement of the patches with respect to the capacitive sensor layer.
