Abstract: A tactile sensor includes a pressure transducer encapsulated in an elastic material that defines a contact surface and provides a transmission path that transmits contact forces or pressure distributions applied to the contact surface to the pressure transducer. The pressure transducer can be enclosed in a protective housing that defines a chamber around the transducer. The housing can include one or more openings that expose the chamber to the exterior pressure. The tactile sensor can be made by applying the elastic material in liquid form and exposing the housing to a vacuum that removes air inside the chamber allowing the liquid elastic material to flow into the chamber. Once cured, the elastic material defines a contact surface of the tactile sensor and serves to transfer contact forces applied to the contact surface to the transducer.

Abstract: The invention relates to a system for measuring cell turgor pressure (dendroturgometer), which can also operate as a firmometer. The system can also be used as an automatic dripper, wherein in this embodiment it is kept pressed by means of a flattening plate (1) against the organ (4), as well as by employing a brace (6) provided with a spring (5) that applies stable force of a magnitude higher than the product between the water pressure, regulated by a pressure adjuster (10) and the fluid layer (2) under the membrane (3), on which the plant exerts compression and obstructs the water flow. The dripping is started when the transpiration provides a drop in the cell turgor pressure of the plant, so that the resulting pressure will be lower than the adjusted water pressure. This system may also be miniaturized and used for measuring the vegetable turgor pressure by using water pressurization with an plunger (11). The cell turgor pressure is achieved with a pressure transducer (12), as the lower pressure applied that forces the passage of water through the layer (2). Alternatively, the system may be mounted for operation as a dendroturgometer in a closed system with a cover (13), and a pressure transducer (12), while a brace applies press force with a spring (5) to enable continuous reading of the turgor pressure in the stern.

Abstract: The present invention concerns a method of adjusting (taring), or re-calibrating respectively of an apparatus comprising a previously pressurized liquid-filled flexible tube, such as used in the steering mechanism of vehicles (steering wheel, handlebar) for detecting panic reactions by the driver and for activating safety measures, or for detecting the presence of a person sitting on the seat of an automobile and e.g. for measuring the weight of that person and for accordingly adapting the safety measures.According to the present invention, in determining the differential between the external pressure exerted by a person onto the flexible tube and the pressure prevailing in the previously pressurized tube, the variations of the pressure in the previously pressurized tube caused by variations of one or more variable ambient parameters (such as e.g. the temperature and/or the barometric air pressure) are taken into accountOwing to these measures the measuring system functions with the previously pressurized flexible tube exactly, and independent of any variations occurring in ambient conditions prevailing in the vehicle.

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.
