B60R 21/16
G08B 21/00

US Classification:

324681, 280735, 340667

Abstract:

A method includes measuring a first frequency response of an electrode at a first frequency across a range of environmental conditions, measuring a second frequency response of the electrode at a second frequency across the range of environmental conditions, and comparing the first and second frequency responses measured to define a data set representing an effect of the environmental conditions. An occupant detection system includes an electrode and a detector circuit. The detector circuit is configured to measure an actual frequency response of the electrode and compare the actual frequency response to the data set to determine the effect of the current environmental condition.

International Classification:

G01L 1/26

US Classification:

73862391, 73760

Abstract:

An occupant presence sensor apparatus disposed in a seat includes first and second substantially non-compliant force translation plates generally parallel to the seating surface of the seat, an elastomeric mat disposed between the first and second force translation plates, and a switch mechanism disposed between the first and second force translation plates within an opening formed in the elastomeric mat. The elastomeric mat includes a distributed array of hollow protuberances that extend toward and contact the force translation plates, and the mat has a stiffness that normally provides a clearance between the switch mechanism and one of the force translation plates. When an occupant of specified or higher weight sits on the seating surface, the protuberances collapse and the force translation plates activate the switch mechanism.

Assignee:

International Classification:

A47C 31/12

US Classification:

2972172, 2972173, 180273

Abstract:

A seat assembly is provided that can be sat upon by an occupant that detects the weight of the occupant. The seat assembly includes a seat cushion, a rotary sensor, and a linkage having a tip. The seat cushion deforms in response to the weight. The rotary sensor has a shaft that rotates about an axis and has an electrical output that is proportional to the angle of rotation of the shaft. The linkage underlies the seat surface and connects the seat surface to the shaft of the rotary sensor. As weight is placed on the seat the seat cushion deforms in response to the weight moving the tip and the linkage. The movement of the linkage rotates the shaft, which in turn, provides an electrical output that is proportional to the weight.

US Classification:

3404255, 340506, 340 31, 340933, 34042624

Abstract:

An occupant system includes a sensing device disposed in a seat and an electronic device configured to acquire data from the sensing device. The electronic device includes a system controller which uses that data to determine an appropriate system response. Data is acquired in at least two different system configurations and in at least two different time periods. A data set is created which represents a comparison of data acquired in the different configurations and times. The elements of this data set are compared to each other to identify anomalous data and respond accordingly.

Abstract:

An occupant detection system that includes an electrode arranged proximate to an expected location of an occupant for generating an electric field between the electrode and the occupant proximate thereto. An electrical network coupled to the electrode forms a resonant circuit that includes the occupant as part of the resonant circuit. A controller coupled to the resonant circuit is configured to determine a resonant frequency of the resonant circuit indicative of an occupant presence, and a network signal magnitude at the resonant frequency indicative of a humidity value proximate to the electrode. . A method for detecting a vehicle applies an excitation signal to the resonant circuit, determine a resonant frequency of the resonant circuit and determines a humidity value based on a network signal magnitude at the resonant frequency.
