摘要： A measurement technique determines the physical features of a tire such as a determination of the deformation a tire undergoes during use. The measurement technique utilizes a first belt, or first and second belts, in the tire reinforced with a plurality of metallic wires and involves the steps of providing a signal between a first and a second metallic wire associated with the first or first and second belts. The measurement technique determines a real part and an imaginary part of the impedance between the first and second metallic wires, which is proportional to the forces acting on the tire.

摘要： A method of and system for providing user input to a computer captures a first finger position image at a first time and a second finger position image at a second time. The first and second finger position images each comprise a plurality of numerical gray scale values equal to or greater than zero. The system then subtracts the first finger position image from the second finger position image to obtain a composite image. The composite image has a first region comprising numerical values less than zero and a second region comprising numerical values greater than zero. The system provides X-Y input to the computer based upon the relative positions of first and second regions. The system further provides Z input to the computer based upon the relative sizes of said first and second regions.

摘要： A circuit technique to reduce the input capacitance line of a charge integrator is described. This approach is particularly tailored for embedded read-out circuits in solid-state integrated sensors. An integrated charge amplifier described herein includes a generic amplifier element and a high speed buffer which drives a metal shield placed underneath the input line. The metal shield therefore follows the potential of the input line and thereby reduces the capacitance between the input line and ground.

摘要： First entities consisting in cells or microorganisms (BIO) and second entities consisting in compounds or compound units, carried typically by microbeads (BEAD), are trapped selectively within closed movable potential cages (S1) by means of dielectrophoretic force generated by mutually opposed electrodes (M1, M2). The cages are set in relative motion so as to bring about the interaction of selected first and second entities, causing the cages containing them to fuse, whereupon results are obtained preferably by reinstating the original cages and/or observing previously empty adjacent cages. The procedure takes place in a device (DE) with two separate chambers (F, FL) connected one to the other by way of a narrow passage (D) and finished with respective selectively controllable inlets and outlets (I1, I2; O1, O2) through which a liquid or semi-liquid buffer (L) can be pumped in or out.

摘要： Disclosed is a method and associated apparatus for compensating for kTC noise in individual pixels of an MOS imaging array. The kTC noise at issue forms when a pixel is disconnected from a reset voltage by turning off an MOS transistor which controls access to the pixel photodiode. Compensation is accomplished by first exposing the photodiode to the reset voltage and then disconnecting the well region from V.sub.dd to cause it to float. By allowing the well to float, the kTC charge subsequently introduced (at the conclusion of the reset process) redistributes so that most of it accumulates on the capacitor between the well and the substrate. Later, the well is reclamped to V.sub.dd, and the noise contribution stored in the well-substrate capacitor is canceled. A disclosed apparatus includes an array of pixels, each having a separate well. In addition, access of the well to a source of power (V.sub.dd) must be switchable. Therefore, a transistor is included at each pixel's connection to a V.sub.dd.

摘要： A device for detecting the pressure exerted at different points of a flexible and/or pliable object that may assume different shapes, includes a plurality of capacitive pressure sensors and at least a system for biasing and reading the capacitance of the sensors. The requirements of flexibility or pliability are satisfied by capacitive pressure sensors formed by two orthogonal sets of parallel or substantially parallel electrodes spaced, at least at each crossing between an electrode of one set and an electrode of the other set, by an elastically compressible dielectric, forming an array of pressure sensing pixel capacitors. The system for biasing and reading the capacitance includes column plate electrode selection circuits and row plate electrode selection circuits and a logic circuit for sequentially scanning the pixel capacitors and outputting pixel values of the pressure for reconstructing a distribution map of the pressure over the area of the array.
