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: 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. Weight sensing pad 10 is defined by a bladder member 15 having an interior volume subdivided into a plurality of individual cells 42 in fluid communication with each other and that is filled with a non-compressible fluid 18, such as silicon or a silica gel of medium viscosity. A pressure tube 22 is in fluid communication with bladder 15 and is in further fluid communication with a pressure activated electronic transducer 26 which in turn is in electronic communication with the airbag controller 30. When a person sits upon weight sensing pad 10, there is a volumetric displacement of fluid 18 that provides a pressure change in the bladder member. If there is a sufficient pressure change due to the volumetric displacement of fluid to activate transducer 26, transducer 26 sends a signal to air bag controller 30. Electronic transducer 26 is selected to generate a signal upon detection of pressure resultant from the volumetric displacement of fluid 18 from bladder 15 expected from the average size adult of approximately one hundred pounds or heavier.

Abstract: An improved weight estimation apparatus in which a closed, multiple cell elastomeric bladder filled with fluid is installed in the foam cushion of a vehicle seat bottom, with at least one pressure sensor installed in a closed exit port of the bladder. The multiple cells of the bladder are formed by a pattern of spot welds between the top and bottom layers of the bladder, creating an array of generally circular or hexagonal cells between which the fluid can freely flow. The array of cells maximizes the pressure response for improved sensitivity, and minimizes the amount of fluid required to detect occupant weight, thereby minimizing the weight of the fluid-filled bladder. The pattern of spot welds in the vicinity of the pressure sensing location may be altered to reduce sensitivity to forces applied in proximity to the exit port. In a first embodiment, a more dense pattern of spot welds is provided in the vicinity of the exit port, while in a second embodiment, continuous welding is used to form a pattern of closed fluid-free pockets in the vicinity of the exit port.

Abstract: A hydrostatic weight sensor incorporates a bladder having a plurality of cells in fluid communication with one another, and with the outlet of a check valve, the inlet of which is in fluid communication with a source of sensing fluid, preferably the atmosphere. Cell-filling and cell-evacuating restoring mechanisms are operatively coupled to respective portions of the cells of the bladder. When the applied load is removed from the hydrostatic weight sensor, the volume of those cells operatively coupled to the cell-filling and cell-evacuating restoring mechanisms are respectively restored and evacuated, whereupon if the pressure becomes less than the local atmospheric pressure, then fluid is added to the bladder through the check valve, thereby restoring lost sensing fluid. A pressure sensor operatively coupled to the bladder generates a signal responsive to the pressure of the sensing fluid within the bladder, and a signal processor calculates the weight of the occupant therefrom.
