Holger Lenhard 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: 7671755
    Abstract: A battery current sensing device for the battery of a vehicle includes a current sensor, a substrate having a measuring circuit, and a connecting element having first and second ends. The current sensor is connected to the battery to receive current flow of the battery. One end of the connecting element is electrically and mechanically connected to the substrate and the other end of the connecting element is electrically and mechanically connected to the current sensor such that the connecting element electrically and mechanically connects the substrate in a fixed position to the current sensor with the measuring circuit being electrically connected to the current sensor. The first end of the connecting element includes a press-fit contact for establishing the connection to one of the current sensor and the substrate.
    Type: Grant

  • Patent number: 6023108
    Abstract: An electrical switching circuit for a plurality of electrical consumers which are disposed preferably in a motor vehicle and which can be switched on and off respectively by way of a switching device in the proximity of the electrical consumers and which are connected on the one hand directly to one pole of a d.c. supply, wherein for the purpose of reducing the number of connection lines each electrical consumer together with its switching device in the proximity thereof is connected to an electronic unit comprising a power stage and a control stage by only one electrical line and a change in the switched state of a switching device is detected by the control stage by way of its monitoring input connected to the power stage and is used by way of its control output likewise connected to the power stage in order to switch over the associated power driver.
