Abstract: An integrated circuit with at least one antenna for the contactless transmission of data or energy. The antenna is configured above and/or below circuit sections to be protected and, as part of a protective circuit, enables the integrated circuit to be monitored with regard to an undesirable external attack. Such an attack can be identified by the attempt to effect observation or manipulation from the outside, which are typically associated with an alteration of the physical properties of the antenna. These physical alterations lead to significant changes in the protective circuit signals that are transmitted via the antenna. These changes are identified by signal detectors and initiate a transfer of the integrated circuit into a security mode. In this case, in addition to the function as means for transmitting data and/or energy, the antenna also serves the function of being a protective shield of a protective circuit for the integrated circuit.

Abstract: Connection of batteries to the DC bus lines across which capacitors are connected in power systems, such as uninterruptible power systems, is carried out using an auxiliary switch which is controlled to connect the batteries to a DC bus line through a precharge resistor momentarily before connection is made through a main connector. The preconnection of the batteries through the precharge resistor provides a controlled rate of charge of the capacitors before closing of the main connector to thereby avoid excessive surge currents. When the main connector is opened, as when the power system is prepared for transportation or long term storage, the auxiliary switch interrupts the current path from the battery through the precharge resistor and provides a current path from the DC bus line through a discharge resistor to ground to bleed down the charge on the capacitors to a desired level within a selected period of time.
