Abstract: The invention relates to a method for monitoring the pressure in a device for the pneumatic adjustment of a seat in a transportation means, in particular in a motor vehicle. The device comprises a plurality of cushions (101, 102, . . . , 105) which are able to be filled with air and which are connected via respective valves (201, 202, . . . , 205) to a common preliminary pressure volume (3), wherein a pressure sensor (4) is provided for measuring the pressure (p) in the preliminary pressure volume (3) and the preliminary pressure volume (3) is coupled to a compressor (6) for supplying compressed air without a non-return valve being connected therebetween. For the purpose of monitoring the pressure in a respective cushion (101, 102, . . . , 105), a predefined pressure is set in the preliminary pressure volume by way of operation of the compressor (6) and/or by way of air discharge from the preliminary pressure volume (3) via at least one leak, with the valve (201, 202, . . . , 205) between the respective cushion (101, 102, . . . , 105) and the preliminary pressure volume (3) closed, wherein the predefined pressure deviates from a target pressure (p1, p2, . . . , p5) in the respective cushion (101, 102, . . . , 105) by at most 10% of the target pressure and/or at most 50 hPa. After the setting of the predefined pressure, the valve (101, 102, . . . , 105) between the respective cushion (101, 102, . . . , 105) and the preliminary pressure volume (3) is opened and the pressure in the preliminary pressure volume (3) is measured via the pressure sensor (4). If the measured pressure (p) deviates from the target pressure (p1, p2, . . . , p5), the measured pressure (p) is set to the target pressure (p1, p2, . . . , p5) by way of operation of the compressor (6) and/or by way of air discharge from the preliminary pressure volume (3) via the at least one leak.

Abstract: A gauge wheel load sensor for an agricultural planter having a row unit that includes a pivotably mounted gauge wheel and a down pressure controller for controlling the down pressure on at least a portion of the row unit. The load sensor includes a mechanical element mounted for movement in response to the downward force applied to the row unit; a fluid-containing device containing a movable element coupled to the mechanical element for changing the fluid pressure in response to the movement of the mechanical element; and a transducer coupled to the fluid-containing device for producing an output signal in response to changes in the fluid pressure. An energy storage device, such as an accumulator, may be coupled to the fluid-containing device for receiving a limited amount of fluid in response to changes in the fluid pressure to damp pressure spikes in the output signal of the transducer.

Abstract: A sensor including a layer having viscoelastic properties, the layer comprising a void, the void filled with a fluid; and optionally, a more rigid sensing element embedded within the layer. When a force is applied to a surface of the sensor, the shape of the void changes, causing the electrical resistance of the fluid in the void to change. When included, the more rigid sensing element can bear upon the void to cause the electrical resistance of the fluid in the void to change. A direction and intensity of the force can be determined by measuring the change of the electrical resistance of different voids positioned about the sensing element. The layer can be an elastomer, preferably silicone rubber. The fluid can be a conductive liquid, preferably Eutectic Gallium Indium. The sensing element can be plastic and can have a “Joystick” shape. The voids can take the form of channels or microchannels having a predefined pattern and/or shape.
