A capacitive sensing apparatus for a vehicle seat includes a deflectable dielectric mat and a flexible printed circuit that wraps around the major surfaces of the dielectric mat to define upper and lower conductor strips that overlap in a direction perpendicular to the dielectric mat. Overlapping regions of the conductor strips define an array of capacitive load cells distributed over the seating surface. A connector stub depending from the flexible printed circuit couples the conductor strips to an external circuit that measures the capacitance of the various load cells to determine occupant weight and weight distribution.

A system for use in classifying a vehicle includes a capacitive sensor for operatively receiving a weight of a vehicle and a capacitance detector coupled to said capacitive sensor. The capacitance detector is adapted to determine a capacitance signal of the capacitive sensor in response to the capacitive sensor operatively receiving the weight of the vehicle.

A capacitive load cell includes upper and lower capacitor plates and an intermediate array of dielectric pads formed of silicone-impregnated open-cell urethane foam (i.e., gel pads). The silicone essentially displaces air that would otherwise be trapped in the foam, contributing to a dielectric having minimal humidity-related variability. The upper capacitor plate is defined by an array of individual charge plates, the lower capacitor plate defines a ground plane conductor common to each of the charge plates, and the dielectric pads are disposed between the ground plane conductor and each of the charge plates, leaving channels between adjacent dielectric pads. When occupant weight is applied to the seat, the dielectric pads transmitting the weight distend laterally into the channels to reduce the separation between the respective upper and lower capacitor plates, and the consequent change in capacitance is detected as a measure of the applied force and the force distribution.

A balance ( 1, 101 ) has a weighing pan ( 4, 104 ) for receiving a load ( 5, 6, 25 ) to be weighed, and an electronic weighing module ( 27 ) which includes a measuring unit ( 28 ). The balance is equipped with an electrostatic sensor ( 10 ) which is arranged so that accumulated electrostatic charges which reside on the load can be detected as the load is placed or about to be placed on the weighing pan. The balance is operated by using the electrostatic sensor to detect electrostatic charges, transferring information on a value characterizing the magnitude of the detected electrostatic charges to the measuring unit, comparing the value against a threshold value, and triggering an action of the electronic weighing module based on the comparison.

A capacitive occupant sensor for a seat has a dielectric in the form of a fluid-filled elastomeric bladder, and the sensor includes a primary region that is subjected to occupant force and a secondary region that is shielded from occupant force. The secondary region includes an appendage of the bladder that is disposed beneath a back cushion of the seat, either in a cavity of the seat cushion or below a frame element that supports the seat cushion. A spring clamp normally biases fluid out of the appendage, but occupant-related force applied over a broad area of the seat produces a flow of bladder fluid into the appendage against the bias force of the spring clamp. A pair of auxiliary conductor plates is oppositely disposed about the bladder appendage, and the capacitance between the auxiliary conductor plates is measured as an indication of fluid pressure in the bladder.
