    Abstract: A surface-conforming obscured feature detector includes a plurality of sensor plates flexibly connected together, each having a capacitance that varies based on the dielectric constant of the materials that compose the surrounding objects and the proximity of those objects. A sensing circuit is coupled to the sensor plates to measure the capacitances of the sensor plates. A controller is coupled to the sensing circuit to analyze the capacitances measured by the sensing circuit. One or a plurality of indicators are coupled to the controller, and are selectively activated to identify the location of a relative high capacitance, which can be indicative of an obscured feature behind a surface.

  • Patent number: 8587328
    Abstract: An apparatus and method for determining characterizing attributes of an actuator is provided. An actuator may be moved to a maximum capacitance position. At the maximum capacitance position, an initial measurement of the actuator capacitance is made. The actuator is moved a predetermined increment toward a first extreme position, and the actuator capacitance is again measured. If the capacitance changed by a threshold amount, the signal preceding the signal that caused the actuator to move is recorded as an approximate response curve end point, or the first extreme position. The actuator is again moved a predetermined increment toward a second extreme position. After each move, the capacitance is measured. If it is determined the capacitance did change by a threshold amount from the previously measured capacitance, the signal related to the previously measured capacitance is recorded as an approximate response curve end point, or the second extreme position.

  • Patent number: 8521471
    Abstract: A system and method by which thickness of a dielectric film on substrates can be noninvasively determined is invented. The system and method are especially applicable to areas and applications where traditional techniques have proven unsuccessful or limited. According to embodiments of the present invention the present system and method can be used to measure film thickness in confined and inaccessible locations, and on substrates of complex geometry. The method can be used with an arbitrary and time varying orientation of the substrate-film interface. The measurements of the film thickness on the inside of open or enclosed channels of an arbitrary geometry, and on flexible substrates are possible. With multiple embedded sensors, the film thickness in different lateral locations can be simultaneously measured. The dielectric permittivity of the FUT as a function of the distance from the substrate of the film can also be measured.

  • Patent number: 8476912
    Abstract: An obscured feature detector operates from a stationary position on a surface being examined. The detector includes a plurality of sensor plates positioned in an array on the underside of the device, which sense the examined surface. The sensor plates are connected to a capacitance sensing circuit, which connects to indicators positioned on the back side of the detector through additional circuitry. A handle positioned on the back of the detector allows the user to grasp the device and place it in a stationary position on the surface being examined while also observing the indicators on the back side of the detector. Increases in capacitance caused by the presence of features behind or within the surface being examined are detected by the sensor plates and the capacitance sensing circuit. The indicators identify locations of larger capacitances, associated with the presence of a feature, such as a stud, beam, or electrical wiring.
