  • Monitoring circuit for an energy store and method for monitoring an energy store
    Patent number: 8310240
    Abstract: A monitoring circuit is provided for an energy storage device. The energy storage device has a plurality of cells which each provide a voltage between their first and second connections and are switched in series. At least two voltage measuring circuits are provided, wherein the voltage measuring circuits each measure the voltage between a first measurement input and a second measurement input. A first connection conductor connects the first terminal of the first cell to the first measurement input of a first voltage measurement circuit. A second connection conductor connects the second terminal of the first cell to the second measurement input of a first voltage measurement circuit. A first load resistor can be switched between the first measurement input of the second voltage measurement circuit and a first fixed potential.

  • Method and device for determining a variable characteristic of a mass that rests on the seating area of a seat
    Patent number: 7444244
    Abstract: A method and a device allow to detect and optionally to indicate the improper use of a seat. For this purpose, an estimated value of a variable characteristic of a mass that rests on a seating area of a seat is determined depending on at least one force that acts upon the seating area and that is detected by one or more force sensors. The estimated value is found to be reliable or unreliable depending on the oscillation behavior of the measured signal of the at least one force sensor.
