  • Publication number: 20010054896
    Abstract: A method for operating an eddy current sensor (10) with a measuring coil (2) and an evaluation circuit (4) for determining material or geometric parameters of a test object (5), in which the test object (5) is arranged at a distance (d) from the measuring coil (2). The impedance of the measuring coil (2) is evaluated, while the measuring coil (2) is being supplied with an alternating voltage of a predetermined frequency, and the evaluation circuit (4) determines the material and geometric parameters of the test object (5) based on the impedance of the measuring coil (2). The impedance of the measuring coil (2) is determined at an alternating voltage of a first frequency, and the impedance of the measuring coil (2) is determined at an alternating voltage of a second frequency, and the evaluation circuit (4) computes the material and geometric parameters of the test object (5) on the basis of the impedances of the measuring coil (2) at the first and the second frequencies.

  • Patent number: 6318153
    Abstract: A sensor (1) is proposed for noncontacting thickness gauging on films (2), in particular blown films, with a sensor head (3) and a mount (4) for the sensor head (3), which provides reliable measuring results despite transportation-caused movements of the film (2), and which is particularly suitable for a continuous quality control during the production process. In accordance with the invention, the sensor head (3) comprises at least one noncontacting sensor element for gauging the thickness in accordance with the physical properties of the film (2). Furthermore, the position of the sensor head (3) is adjustable such that the sensor head (3) is held during the entire measuring process at a predeterminable, at least largely constant distance from the film (2).

  • Patent number: 6286974
    Abstract: An innovative, unique visual display for a powered car audio amplifier. The audio amplifier includes a transparent cover plate, preferably formed of methyl methacrylate, having a name or pattern etched or engraved in the undersurface of the cover plate. A black light or neon gas light tube surrounds an edge of the cover plate. The light produced from the black light or neon glass tube is transmitted through the cover plate and is collimated at the etched or engraved pattern in the cover plate. The pattern appears illuminated when the pattern is viewed through the cover plate without any visible source of light present. The light also appears to highlight the circuitry of the amplifier chassis located below the cover plate.

  • Patent number: 6246230
    Abstract: A noncontacting displacement sensor (1) is proposed with a measuring coil (2) to which alternating current can be applied, the measuring coil (2) having at least two voltage taps (3), with an electrically and/or magnetically conductive measuring object (5), and with an evaluation circuit (4) for evaluating and, if need be, determining an output voltage that corresponds to the position of the measuring object (5) with respect to the voltage taps (3). To provide the displacement sensor of a structural form that is as compact as possible, the measuring object (5) is arranged and displaceable in the interior of the measuring coil (2), the total impedance of the measuring coil (2) being independent of the position of the measuring object (5).

  • Patent number: 6202929
    Abstract: Barcode patterns or other meaningful patterns are printed with a differentially conductive ink. A sensor incorporating a plurality of capacitive couplings distinguishes features of the patterns by comparative measurements that are largely independent of variations between the sensor and the patterns affecting all of the couplings. The patterns can be distinguished despite being hidden from view, such as inside sealed envelopes.

  • Patent number: 6100846
    Abstract: An antenna, particularly adapted to produce a scanning beam usable for radar and communication applications, includes a frame. Attached to the frame is a reciprocating device that is operatively connected to a reflecting conductor. Spaced by a uniform gap from the conductor is an elongated dielectric waveguide carried on a conductive layer of a laminate supported by the frame on an input side of the antenna. The waveguide covers a set of spaced apart apertures in the laminate conductive layer. Joined to the laminate conductive layer on an opposite output side of the antenna is a dielectric layer. On an outer surface of the laminate dielectric layer is a set of spaced apart conductive patches that align with the laminate conductive layer apertures. During operation of the antennas an electromagnetic wave is transmitted through the waveguide to pass through the laminate apertures and energizes the patches.

  • Patent number: 5946188
    Abstract: A car amplifier has a housing for containing a circuit board retaining electronic components, and a cooling unit. The cooling unit draws heat away from heat generating elements which are mounted on the circuit board. The cooling unit has two heats sinks formed as first and second tunnels. The first tunnel has an arm that contacts the heat generating elements and draws heat therefrom. Each tunnel forms an interior passage and has open ends. Fins are located on the interior of the tunnels, so that heat is dissipated to the interior passages. A fan is mounted to one end of each tunnel to force air out from the passage of the first tunnel and draw the air back along through the passage of the second tunnel and to the exterior of the housing. The tunnels are separated by a peltier device, which has a cool side abutting the first tunnel and a hot side abutting the second tunnel. Hence, the cool side cools the first tunnel, while transferring heat to the second tunnel.

  • Patent number: 5898304
    Abstract: A sensor arrangement (1) comprising at least one measuring coil (2), at least one voltage source (3) for the measuring coil (2), and an evaluation unit (4) with means for detecting, processing, and evaluating measured signals. This sensor arrangement (1) is used to measure distances and thicknesses substantially independently of the material involved, without the user having to know the physicomathematical relations between the influencing quantities and the measured values. In order to evaluate the measured signals, the evaluation unit (4) of the sensor arrangement comprises a neural network (5) with an input layer, at least one hidden layer, an output layer, and connection weights for the individual layers. The connection weights are determined and stored in a learning phase by measurements taken on a plurality of different suitable learning objects with known actual values.

  • Patent number: 5569385
    Abstract: A process for the rendering of an effluent stream from a food processing plant, in which the effluent has or is made to have an acidic pH and carries proteinaceous material. The effluent is contacted with an inorganic coagulant (clay) that together with the acidic pH effectively neutralizes ionic charges on the proteinaceous material to cause the proteinaceous material to precipitate out of solution. The effluent stream is contacted with a biologically derived polymeric flocculant to facilitate settling of the precipitated proteinaceous material as flocs. The inorganic coagulant is present in an amount by weight of at least 1.5 times or 2.5 times the amount by weight of polymeric flocculant. Flocs are removed from the effluent stream to thereby render the effluent stream. A biologically derived co-flocculant is added to the effluent stream after contact with the effluent stream by coagulant and flocculant.

  • Patent number: 5423556
    Abstract: An interactive computer game uses a digital computer system with a display and an interactive means for communicating user input to the computer system. The system displays on the display an array of elements in rows and columns, each of the elements having a feature distinguishable by a player of the game. In addition, at least one element can be moved by the user via the interactive means. This element can be added at one end of a row or a column of the array thereby shifting this row or column by one element and removing another element from an opposite end of the row or column. When a row or a column is formed in which the elements have a predetermined pattern of features, that row or column is erased from the display. If, within a given time interval, a player is unable to build such a row or a column which has a predetermined pattern of features, the system adds a new row or column of elements to the display.
