Abstract: A sensing system determines movement and position of passengers and objects within a vehicle. In particular, the determination of the position and movement of body parts can be enhanced by providing features that provide a source of ground for the system. The sensing system is able to transmit a plurality of signals during a transmission period and use the sensed signals during a frame in order to create different heat maps that represent movement and position of person during an integration period. By taking advantage of grounding sources, the system is able to better determine the position and movement of a person or object.

Abstract: A sensing system determines movement and position of passengers and objects within a vehicle. The sensing system comprises a group a group of transmitting antennas operably connected to a car seat, each transmitting antenna adapted to transmit a signal that is orthogonal to each other signal transmitted during an integration period; a plurality of receiving antennas, each one of the plurality of receiving antennas adapted to receive transmitted signals; and a processor adapted to determine a measurement of the transmitted signals received and create a heatmap, wherein a heatmap summation is taken during no-touch events, compared to a baseline heatmap, and a new baseline heatmap recalibrated if a threshold is exceeded.

Abstract: A multi-modal sensor is disclosed that is able to detect and discriminate objects in the near-range range, mid-range and far-range. The sensor uses different sensing modalities that are adapted to cooperate and operate together depending upon the range of the object that is being detected. In an embodiment, infrared transmitters and infrared sensors are used, wherein the infrared transmitters transmit signals in the infrared range that frequency orthogonal with respect to each other.

Abstract: Embodiments provide metamaterials having an enhanced nonlinear response to light. The metamaterials are artificially manufactured materials having a nonlinear response to light greater than that typically found in naturally occurring materials. A two-dimensional periodic metal-dielectric array can be mathematically mapped as an effective uniform dielectric slab with enhanced optical nonlinearity. The enhanced nonlinearity is controlled by the geometry of the array. Further, the configuration of the array can be applied to form three-dimensional structures having an enhanced nonlinear response to light.
