Abstract: A compliant tactile sensor may include sponge-like material, a flexible skin, and a fluid pressure sensor. The flexible skin may have a shape, absorb fluid, compress in response to force applied to the sponge-like material, and decompress and return to its original shape when the force is removed. The flexible skin may cover an outer surface of the sponge-like material. The fluid pressure sensor may sense changes in pressure in fluid that is within the sponge-like material caused by a force applied to the flexible skin. A robotic system may include a movable robotic arm, a compliant tactile sensor on the movable robotic arm that senses contact between the compliant tactile sensor and an object during movement of the movable robotic arm and that cushions the effect of that contact, and a reflex system that causes the moveable robotic arm to move in response to commands.

Abstract: A sensor pad for controlling the deployment of an automobile airbag. Weight sensing pad 10 is used in the seat 54 of an automobile, (not illustrated), to detect the presence of an occupant on the seat. Weight sensing pad 10 is used in conjunction with the vehicle's airbag control module in order to allow deployment of the airbag, in the event of a collision, only if the seat is occupied by a person of a preselected weight.

Abstract: An improved pressure-based weight estimation system that includes an adaptive technique for reliably and accurately determining the vacant, or unoccupied, seat pressure. The vacant seat pressure is initially determined by a factory calibration procedure, and is thereafter suitably updated by an adaptive learning algorithm based on temperature, time, and the measured pressure. If the seat temperature is within a normal range, and the measured pressure remains at least a predetermined amount below the calibrated vacant seat pressure for at least a predetermined time, a fraction of the difference between the measured and calibrated values is subtracted from the calibrated value to form a new calibration value. The predetermined difference amount determines the sensitivity of the control, and the predetermined time prevents adaptive correction of the calibration value due to transient pressure conditions.
