Abstract: A method for charging an energy store of a field device having at least one charging current source and a control unit in which the charging current source loads the energy store of the field device with a charging current. A field device carrying out the method includes a chargeable energy store, at least one charging current source and a control unit. The useful life of the field device can be increased by the method and the field device according to the disclosure.

Abstract: Sensor having a control unit, configured to analyze data available to the sensor, in particular measurement data of the sensor, for generating power management data, the power management data being configured to for select a power saving mode from a plurality of available power saving modes of a wireless module (103) of the sensor and/or for controlling the times of measurement intervals of the sensor and/or for power management of the sensor.

Abstract: The present invention describes a method for data transmission between an integrated circuit and an evaluation unit connected to an interrupt pin of the integrated circuit, characterized in that the data transmission is carried out by selectively triggering an atypical interrupt signal or a plurality of interrupt signals composed of regular and/or atypical interrupt signals.

Abstract: A measuring device is provided for fill level measurement, for limit level determination, for pressure measurement, and/or for temperature measurement, the measuring device including: an energy source; at least one controllable switch; an activation device, which is directly connected to the energy source, including a programmable finite state machine, and which is configured to control the at least one controllable switch by the programmable finite state machine; and at least one load connected to the energy source via the at least one controllable switch.
