Patents by Inventor Heinz Ploechinger

Heinz Ploechinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7497118
    Abstract: The invention relates to construction principles, operating and manufacturing methods for inertial sensors, i.e., sensors for rapidly detecting movement and acceleration in all degrees of freedom in space, and for separately detecting the position with respect to the perpendicular under the action of acceleration due to gravity. Use is made of the knowledge that to maintain a common convection zone of two or more sensor elements, the power fractions supplied to these elements vary with change in position, movement and acceleration.
    Type: Grant

  • Publication number: 20050279164
    Abstract: A sensor for detecting position and/or movement in space and/or for detecting fluid-properties comprising at least one transmitter and at least one receiver which are enclosed by a fluid, characterized in that the at least one transmitter generates cyclic fluid density fluctuations and the at least one receiver detects the change in transit time and/or the phase shift and/or the frequency change and/or the amplitude change.

  • Patent number: 6722199
    Abstract: A sensor for detecting a rotational movement or an angular acceleration has at least one heating element and at least one sensor element and a fluid surrounding the heating element and the sensor element, the heating element producing in the fluid a convection flow zone through which an isothermal field is defined. The heating element and the sensor element are arranged with respect to an axis of rotation of the rotational movement or of the angular acceleration to be detected, in such a way that the sensor element is displaced relative to the isothermal field when a rotational movement or an angular acceleration takes place.

  • Patent number: 6675656
    Abstract: A force or pressure sensor structure has a membrane and a counter-structure, both being provided with electrodes for determining capacitors. There are at least two capacitors connected in series or in parallel for determining a desired pressure/capacitance dependence or a desired force/capacitance dependence. The counter-structure preferably is fixed and has a multiplicity of electrode areas in the shape of segments of a circle in order to assemble electrode areas obtained by optimization in a series or parallel connection. The interconnection of the individual elementary capacitors are preferably realized by a multilayer construction. The same membrane and an identical evaluation circuit can be used for any pressure/capacitance or force/capacitance dependence desired, with only the multilayer construction requiring modification for a different dependence. The electrode structures can preferably be defined by a few specifications, such as e.g., length, width, spacing or angle, radius, respectively.

  • Publication number: 20020189349
    Abstract: A sensor (100) for detecting a rotational movement or an angular acceleration comprises at least one heating element (108) and at least one sensor element (110, 112) and a fluid surrounding the heating element (108) and the sensor element (110, 112), the heating element (108) producing in the fluid a convection flow zone through which an isothermal field is defined. The heating element (108) and the sensor element (110, 112) are arranged with respect to an axis of rotation of the rotational movement or of the angular acceleration to be detected, in such a way that the sensor element (110, 112) is displaced relative to the isothermal field when a rotational movement or an angular acceleration takes place.

  • Patent number: 6178818
    Abstract: A capacitive filling level sensor has a first capacitive sensor element arranged close to a fluid whose filling level is to be detected, a second capacitive sensor element arranged close to a fluid whose filling level is to be detected, and a switched-capacitor measuring circuit, which is connected to the first and second capacitive sensor elements and which detects the capacitance values thereof. The switched-capacitor measuring circuit produces in response to the detected capacitance values a signal indicative of the filling level. The first capacitive sensor element and the second capacitive sensor element are each defined by two wires of a ribbon cable having at least five wires, the fifth wire extending between the wires which define the capacitive sensor elements, and being connected to ground.
