  • Patent number: 11119160
    Abstract: A planar Hall sensing element includes a first pair of sensing electrodes mutually opposed in a first direction across the sensing element and a second pair of sensing electrodes mutually opposed in a second direction across the sensing element, with the second direction orthogonal to the first direction. A first pair of bias electrodes is mutually opposed in a third direction and a second pair mutually opposed in a fourth direction across the sensing element, the fourth direction orthogonal to the third direction. The third and fourth directions are rotated 45° with respect to the first and second directions so each sensing electrode is arranged between a bias electrode of the first pair and second pair. A DC bias current is supplied between the first and second pairs of bias electrodes. First and second Hall voltages are sensed at the first and second pairs of sensing electrodes.

  • Patent number: 7755683
    Abstract: The method is for reading a capacitive sensor and may be implemented by a circuit for biasing and reading capacitances that includes circuits for selecting a column line and a row line, and a charge amplifier producing an output voltage representing the capacitance of the selected capacitor intercepted by the selected column and row lines. The method includes preliminarily resetting the output voltage of the charge amplifier, connecting all the deselected row and column plates of the array to a reference voltage and connecting a feedback capacitor and the selected capacitor to an inverting input of the amplifier, applying a step voltage on the capacitor that is connected to the inverting input of the amplifier, and reading the output voltage at steady-state.

  • Patent number: 7699969
    Abstract: 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.

  • Patent number: 7535502
    Abstract: Disclosed is a fault tolerant CMOS image sensor that includes circuitry for identifying defective pixels and masking them during image generation. Masking may involve, in one example, replacing the output of a given pixel with an average of the output of surrounding non-faulty pixels. Thus, while image sensors may be fabricated with some number of faulty pixels, the images produced by such sensors will not have undesirable bright or dark spots. The disclosed sensor includes (a) one or more pixels (active or passive) capable of providing outputs indicative of a quantity of radiation to which each of the one or more pixels has been exposed; and (b) one or more circuit elements electrically coupled to the one or more pixels and configured to identify and correct faulty pixels in the CMOS imager. The one more pixels each include a photodiode diffusion formed in a well and a tap to power or ground also formed in the well.

  • Patent number: 7251991
    Abstract: 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.

  • Patent number: 6998855
    Abstract: A distance sensor has a capacitive element in turn having a first plate which is positioned facing a second plate whose distance is to be measured. In the case of fingerprinting, the second plate is defined directly by the skin surface of the finger being printed. The sensor includes an inverting amplifier, between the input and output of which the capacitive element is connected to form a negative feedback branch. By supplying an electric charge step to the input of the inverting amplifier, a voltage step directly proportional to the distance being measured is obtained at the output.

  • Patent number: 6826968
    Abstract: 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.
