A proximity sensor system includes a sensor matrix array having a characteristic capacitance on horizontal and vertical conductors connected to sensor pads. The capacitance changes as a function of the proximity of an object or objects to the sensor matrix. The change in capacitance of each node in both the X and Y directions of the matrix due to the approach of an object is converted to a set of voltages in the X and Y directions. These voltages are processed by digital circuitry to develop electrical signals representative of the centroid of the profile of the object, i.e, its position in the X and Y dimensions. Noise reduction and background level setting techniques inherently available in the architecture are employed.

An image detecting device has a large dynamic range that deals with a plurality of image detecting modes. The image detecting device is composed of pixels e (i, j) arranged in a matrix array. Each pixel has a photoelectric element. In each pixel, a capacitor 102 and a protecting diode 103 are disposed. The capacitor 102 stores electric charge corresponding to the intensity of penetrated light to the relevant pixel. The protecting diode limits the capacitance. A bias voltage is supplied to the protecting diode 103 through a bias line Bias. The bias voltage is adjusted by a bias voltage controlling system 133 corresponding to the frame rate. Thus, the influence of a leak current in the off-state of the protecting diode 103 can be alleviated against electric charge stored in the capacitor 102. Consequently, an image with a high S/N ratio can be obtained regardless of the frame rate.

A normal force gradient/shear force sensor device and measurement method for measuring internal stresses in tissues of a person supported by a chair or bed includes a planar matrix array of peripheral normal force sensors radially spaced from central shear force sensors, comprising an electrically conductive disk located within a circular opening bordered by circumferentially spaced apart electrodes. The disk and electrodes are located between upper and lower cover sheets made of a stretchable material such as polyurethane; one cover sheet is adhered to the disk and the other sheet is adhered to a support sheet for the electrodes. Motion between the cover sheets in response to shear forces exerted on the array causes the disk to press more or less tightly against the electrodes varying electrical conductance between the disk and electrodes proportionally to the magnitude and direction of the shear force. Each normal force sensor includes an electrically conductive film pressed between row and column conductors. Measurements of conductance values of pairs of sensor, which vary proportionally to normal forces exerted on the sensor, are used to calculate a gradient vector of normal forces exerted by a body part on the sensor array, which is combined with the shear force vectors in an algorithm to calculate internal reaction shear forces, e.g., on flesh near a bony prominence.
