  • the present invention relates to an apparatus and method for controlling battery operated devices, such as mobile operating tables.
  • the (lead) batteries have the property that they have their capacity, i. The ability to store energy will be lost if stored uncharged or discharged beyond a certain level.

Furthermore, the first microprocessor is further configured such that upon receipt of an instruction from the input device, it first sets itself and then the second microprocessor into an active state. This allows a user to exit standby mode by operating an input device and cause the two microprocessors to power up and be put into their active state, such as moving a back plate, leg plates, head plates, hip plates, or other components of the operating table or control components of another battery powered device.
