Abstract: Tactile sensors are disclosed that mimic the human fingertip and its touch receptors. The mechanical components are similar to a fingertip, with a rigid core surrounded by a weakly conductive fluid contained within an elastomeric skin. The deformable properties of the finger pad can be used as part of a transduction process. Multiple electrodes can be mounted on the surface of the rigid core and connected to impedance measuring circuitry within the core. External forces deform the fluid path around the electrodes, resulting in a distributed pattern of impedance changes containing information about those forces and the objects that applied them. Strategies are described for extracting features related to the mechanical inputs and using this information for reflexive grip control. Controlling grip force in a prosthetic having sensory feedback information is described. Pressure transducers can provide sensory feedback by measuring micro-vibrations due to sliding friction.

Abstract: A hydraulic load cell configured to allow direct readout of an applied force in pounds by a standard hydraulic gauge, which is normally calibrated in pounds per square inch. A load is applied generally to the end of the load cell's piston. The piston is fitted with an o'ring in its machined groove and inserted into a fluid filled cylinder; the cylinder having been machined to a tightly controlled diameter of nominally 1.12838 inches. The fluid cavity is joined by a small bore tube to the hydraulic gauge. The three piece device and adjoined gauge is extremely rugged. Pascal's Law of incompressibility of a liquid and the equation of Force=Pressure×Area are utilized to realize the invention's unique simplicity and usefulness. Applications to single and multiple point loading are shown.

Abstract: The invention relates to a device and method for detecting a force on an injection moulding machine for processing plastic materials. According to said invention, a first element (100) interacting with a mechanical drive and movable at least indirectly thereby in a direction of movement (x) is displaced during said displacement with respect to a second element (200) positioned near the first element (100) or oppositely thereto. A force measuring device (D) is used for determining the force applied on the first (100) and/or second (200) element by the actuation of the injection moulding machine produced by the relative displacement thereof between the first (100) and second (200) elements. A hydraulic chamber whose size is modifiable during the relative displacement associated with a change in pressure of a fluid medium in said hydraulic chamber is firmed between the first (100) and second (200) elements, wherein said change in pressure forms an input signal for adjusting the force or pressure and a pressure-relief valve (30) is used for bypassing the hydraulic medium to a hydraulic medium container (35), when the predetermined or predeterminable presser is exceeded in the hydraulic chamber (10), thereby making it possible to obtain a device and method for detecting a force on an injection moulding machine which makes it possible to determine said force in a favourable alternative manner and simultaneously ensure an overload protection.

Abstract: A seat bladder weight estimation apparatus includes an interface panel having multiple regions of substantial rigidity separated by regions of insubstantial rigidity. The regions of substantial rigidity limit sensitivity to seat foam variations, and the regions of insubstantial rigidity permit differential movement and angulation of the rigid regions for regional transfer of occupant weight to the bladder. The regional transfer of occupant weight to the bladder allows regional variation of the bladder sensitivity to occupant weight through various bladder geometry design features.

Abstract: An improved weight estimation apparatus includes a closed elastomeric bladder filled with fluid and 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. A temperature sensor disposed in proximity to the bladder provides a temperature signal, and a controller estimates the weight of the occupant based on the temperature and pressure signals. The pressure sensor is preferably configured to sense the gage pressure--that is, the differential pressure between the fluid and atmospheric pressure--at the center of gravity of the fluid in order to provide a stable output independent of changing atmospheric pressure and changing orientation of the bladder due to vehicle pitch and roll.

Abstract: A method for measurement of axial forces acting on a shaft, being supplied with gas under overpressure such that gas pressure is built up between two opposing faces of said portion projecting radially from the shaft and at least one gas-permeable body provided external to said faces. A gas differential between the gas pressure on said opposing faces is established, and the axial force acting on said shaft is determined as a product of a constant and the pressure differential between the gas pressures on the two faces. Means are provided for supply of gas under overpressure to said body and pressure measuring means are provided for measurement of the pressure differential between the pressures on the two faces of the radially projecting portion. The protruding portion may also constitute a measuring plate which, provided in various manners, is subjected to forces.
