Ulrich Hulsmann 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: 6559614
    Abstract: An electrical circuit arrangement for controlling a unit, such as an adjustment system for windows or a sliding sunroof, that is driven by a motor and is situated in a motor vehicle. The arrangement guarantees that, in the case of a short-circuit of circuit components, especially a control device operation of a motor is still possible, especially in a preferred direction of motor rotation, whereby the direction of rotation results in an opening of the unit and the short-circuit is caused by salt water for instance. Two circuit-breaker elements that operate the motor in either direction can be directly activated by an allocated circuit device which bypasses a failed control device. The remaining circuit-breaker element is blocked at least when the first circuit-breaker element is activated.
    Type: Grant

  • Patent number: 6107713
    Abstract: A drive assembly for driving an adjustable unit in a motor vehicle includes a motor/transmission and an associated control unit. The motor/transmission is suitable for adjusting an adjustable part in a motor vehicle for normal applications. The transmission is driven by the motor to adjust the adjustable part. The motor and the transmission are separated by an interface region. The motor includes a magnetic field generator for generating an alternating magnetic field as the motor drives the transmission. The control unit can be readily connected to the motor/transmission for controlling the adjustment of the adjustable part for more advanced applications. To be readily connected to the motor/transmission, the control unit includes a profiled projection having a hollow chamber. A magnetic sensor is positioned inside the hollow chamber.
