Franz Allmeier 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: 7369383
    Abstract: A protective circuit (1), particularly for overvoltage-protecting an electronic motor control unit, comprises a signal connection receiving and/or emitting an electrical signal, a switching element (4) which activates or deactivates a protective interrupter and is controllable via a control input, and a control circuit (5), the input side of which is connected to the signal connection while the output side thereof is connected to the control input of the switching element (4) in order to activate or deactivate the protective interrupter according to the electrical state at the signal connection. The control circuit (5) has a hysteresis characteristic regarding the electrical state at the signal connection.
    Type: Grant

  • Patent number: 6194951
    Abstract: A voltage UA that can be measured at a junction point between a load and a limit switch when the load is disconnected is compared with a predetermined threshold value W. The limit switch is turned on and off with a predetermined current associated with shallow turn-on and turn-off edges when UA<W, or is turned on and off with a higher current associated with steep turn-on and turn-off edges when UA>W.

  • Patent number: 5570259
    Abstract: A circuit arrangement for controlling a load and for recognizing an interruption in a line to the load includes a measuring resistance connected in series with the load, a device for varying a resistance value of the measuring resistance as a function of a current passing through the load, and a diagnostic device for generating a diagnosis signal if a voltage drop, producible across the measuring resistance by a load current drops below a threshold value.
