Abstract: A system and method for measuring contact pressures between two surfaces, and especially, between the body and a device resting on the body, e.g., the skin and a breathable gas mask. A deformable, resilient probe having a flow passage therein is initially placed between the two surfaces such that the flow passage is blocked. Fluid pressure within the probe is then increased until the pressure in the probe overcomes the contact pressure between the two surfaces, such that fluid begins to flow through the flow passage in the probe. The pressure at which the fluid begins to flow through the flow passage in the probe is recorded as the contact pressure between the two surfaces. Contact pressure maps created using this apparatus and method may be used to create anthropometric models of the face and other body parts.

Abstract: Four load cells supporting a seat or part thereof provide four signals that are added to determine the weight of the seat occupant. Each load cell has two flanged springs stressed to provide preload. The two springs operate in concert to resist side forces and moments, making the load cell responsive to both compressive and tensile forces while being substantially unresponsive to lateral forces and moments tending to cause angular misalignment between input elements. A preferred load cell has a liquid filled chamber and a pressure sensor providing an electric signal indicating the pressure in the liquid, which is related to the applied force. Preferred manufacturing methods make the cost low. A seat belt tension sensor may close a switch at a predetermined seat belt tension or may measure the seat belt tension. A preferred mounting limits side forces to the load cells.

Abstract: A seat occupant weight sensing system includes load cells that receive the weight of a seat occupant. A microprocessor receives indication of force applied to the load cells and may also receive output from a seat belt tension sensor and/or an atmospheric pressure sensor. In a first preferred embodiment four load cells supporting a seat each have a fluid filled chamber, and a pressure sensor in each load cell provides an electric signal indicating the pressure in the fluid. The four signals are added to determine the weight of the seat occupant. In a second preferred embodiment fluid conduits connect the four fluid filled chambers to a common pressure sensor. The load cells comprise two flanged conical springs stressed to provide preload. In the preferred embodiments, a spring is part of the surface of the chamber that confines the fluid. The two springs operate in concert to resist side forces and moments. The load cell is responsive to both compressive and tensile forces while being substantially unaffected by lateral forces and moments tending to cause angular misalignment. The seat belt tension sensor enables distinction between apparent weight caused by force applied by a seat belt to a child seat and the actual weight of a person. A first seat belt tension sensor comprises a switch that closes at a predetermined seat belt tension. A second seat belt tension sensor measures seat belt tension.

Abstract: An improved weight estimation apparatus in which an elastomeric bladder is supported on a semi-rigid backer board which is installed in a vehicle seat between the seat cushion and an underlying spring suspension. The bladder is secured onto the backer board, and the backer board is attached to the seat, enabling proper and consistent placement of the bladder relative to the seat surface. The backer board provides the reaction surface for the bladder, and masks non-uniformities of the seat structure. Additionally, the backer board will reduce or eliminate the effect of objects lying on the floor under the seat, which might otherwise pinch the bladder and produce weight estimation errors. Further, the board tends to protect the bladder from damage due to sharp objects, pinching by the suspension elements, and the effects of wires or cables routed through the seat. The backer board may be smooth to provide a uniform reaction surface, or contoured to increase or decrease sensitivity to weight applied on certain areas of the seating surface.

Abstract: A system for determining the weight of the occupant of a vehicle seat includes a hinge near the forward edge of the seat and a force sensor responsive to downward force at a point well to the rear of the hinge thereby indicating torque about the hinge. The system includes a microprocessor connected for receiving the output of the force sensor. The microprocessor may also receive outputs from an accelerometer responsive to vertical accelerations, a seat back recline angle sensor, a seat track position sensor, a seat belt tension sensor and an atmospheric pressure sensor. In a first embodiment the microprocessor determines the weight of the seat occupant from the outputs of the force sensor and the seat back recline sensor. In a second embodiment the microprocessor determines the weight of the seat occupant from the outputs of the force sensor, the seat back recline sensor and the seat track position sensor. A force sensor comprises a compressible bottle with a Belleville spring thereby being responsive to both compression and tension while resisting lateral forces and being insensitive to angular misalignment and temperature fluctuations. The microprocessor may use the accelerometer or the seat belt tension indicator or the two in combination to establish whether the force being sensed derives from seat belt tension applied to a child seat or from the weight of a person.

Abstract: A force sensor for sensing the weight of a vehicle seat occupant for a vehicle's occupant protection system has a pressure sensor responsive to hydraulic pressure resulting from axial force applied to the force sensor. A constant force spring in the form of a diaphragm with two flanges simultaneous functions as a seal, a constant force bias spring, an armature support resistant to radial forces and a piston for converting force to hydraulic pressure. Two studs receive applied force. An electrical insulator is sealed to the walls of a passage inside of one of the studs to provide electrical communication while sealing against liquid leakage. A pressure sensor is mounted on the electrical insulator and connected to electrical conductors in the insulator by stitch bonding. The diaphragm resists radial movement while allowing axial movement thereby making the sensor insensitive to radial forces. By being a constant force spring the diaphragm makes the sensor insensitive to temperature variations.

Abstract: A weight estimation apparatus for the passenger seat of a motor vehicle, in which a single bladder substantially encompassing the seat bottom is evacuated and then inflated with a known volume of air. The average pressure in the bladder is determined to estimate the passenger weight. According to a first embodiment, the apparatus continues to monitor the average pressure, and the process is re-initiated if the average pressure changes by at least a predetermined percentage. According to a second embodiment, a bleed valve allows the pressure in the bladder to slowly escape, and the apparatus monitors the rate of change in pressure as a corresponding indication of passenger weight; in this embodiment, the process of evacuating and inflating is re-initiated if the monitored change in pressure does not correspond with the estimated weight. The sides of the bladder may be pleated to permit the bladder to expand under the weight of an occupant without stretching the bladder, and thereby affecting the average pressure. A temperature sensor may be disposed in proximity to the bladder provides a temperature signal for compensating the weight estimation for temperature variations. Also, the pressure sensor may be configured to sense the gage pressure--that is, the differential pressure between the bladder pressure and atmospheric pressure; alternatively, the pressure sensor may be configured to detect absolute pressure, and a second absolute pressure sensor responsive to atmospheric pressure may be used to compensate for changes in atmospheric pressure.

Abstract: While a bag (1) made of a thin, soft, and less elastic material is packed with air and is positioned between contacts of soft materials, a thin tube (2) from the bag (1) is lead to the outside of the contacts, and the pressure difference with respect to atmosphere is measured, whereby the contact pressure of an elastic body can be measured. As water depth (A) (mmH.sub.2 O) is measured while the bag (1) is horizontally sank into the water, and as water temperature is changed while the water temperature is measured, the measured level can be calibrated together with thermal influence.

Abstract: The cylindrical internal surfaces of inner races of antifriction bearings between the end portions of a deformable shell and the stationary carrier for the shell in a roll for use in calenders surround with some clearance the adjacent cylindrical external surfaces of the carrier. The magnitude of stresses between the pairs of internal and external surfaces is monitored by several sensors at least some of which have pockets machined into the respective internal and/or external surface. The pockets receive a pressurized hydraulic fluid which leaks along paths defined by the respective pair of surfaces to be collected in a tank. An evaluating system monitors the pressure in the pockets and serves to regulate the pressure of supplied fluid and/or the hydrostatic or other supporting elements between the carrier and the shell.
