Abstract: The electronics comprises a load circuit, a power supply circuit having a rechargeable electrical energy storer, and a protection circuit. An input of the power supply circuit is adapted to be electrically connected with an external energy supply. Both the power supply circuit and the protection circuit have at least two operating modes. Additionally, the protection circuit is adapted in the first operating mode to monitor the cell voltage applied on the circuit input to determine whether its voltage level has exceeded a predetermined maximum value and, in given cases, automatically to deactivate the operating mode.

Abstract: The invention relates to a field device of measurement- and automation technology, comprising: a measuring transducer which is adapted to register at least one measured variable and, at any one time, to output at least a first measured value representing the measured variable; a display unit which is adapted to display measuring- and/or operating parameters; and an electronic measuring/operating circuit which is adapted to operate the measuring transducer and/or the display unit, as well as to calculate from the first measured value a derived, second measured value. The display unit has a screen that has a first region with a first display technology and a second region with a second display technology. The first region is embodied reflectively or transreflectively and the second region is embodied transmissively.

Abstract: An IC (100) for communicating over a data communication bus (220) comprising a first pair of conductors including a data signal conductor (SDA) and a synchronization signal conductor (SCL), e.g. an I2C bus, is disclosed. The IC comprises a group of address pins (106a-c) for defining the bus address of the integrated circuit (100), each address pin being arranged to be coupled to a conductor from a group of conductors comprising the first pair of conductors and a second pair of conductors including a conductor for carrying a fixed high potential (Vdd) and a conductor for carrying an fixed low potential (GND).
