Abstract: A container is created that includes two sides. A front side of the container displays viewable content. A back side of the container displays editing controls corresponding to the viewable content. A button may be displayed that, when activated, switches the display between the front side and the back side. The button may be displayed only while the editing controls are displayed and hidden while the content is displayed. While the content is displayed, the entire display area may be responsive to a user input to cause display of the editing controls. Switching between the front-side element display and the back-side editing display may be accompanied by a flipping animation. Enabling the flip-to-edit container may be based on permissions of a user account.

Abstract: The present invention relates to a device for measuring a battery current of a battery. The device has a measuring distance, over which the entire battery current to be measured flows during the measurement. A measuring device measures a voltage drop across the measuring distance. On the basis of the measured voltage drop and a resistance of the measuring distance, a current determining device determines the battery current, wherein the measuring distance is formed by at least part of a cable with a temperature-dependent resistor.

Abstract: A battery sensor has a current meter, an analytical unit, and a microprocessor. During an idle phase, in which the electrical main user, provided with a battery, is switched off, the following steps are carried out. The microprocessor is switched off. At given intervals the measured signal from the current meter is recorded for a given first duration by the analytical unit and allocated first current values which are monitored in the analytical unit for exceeding a first current threshold or dropping below a second current threshold. On exceeding or dropping below the current thresholds, the microprocessor is switched on and, for a given second duration, the measured signal from the current meter is recorded by the analytical unit and allocated second current values which are then analysed in the microprocessor. Procedures for obtaining the electrical charge of the battery by the microprocessor are initiated when a given condition is met, which is dependent on the second current values.

Abstract: A device monitors the operating parameters of a battery, in particular a starter battery for an automobile. The operating parameters include at least the battery voltage and the device is supplied from the battery voltage. For power-saving and yet precise determination of operating parameters for the period of time which is particularly significant in practice after a drop in the battery voltage, the device comprises a battery parameter detection device which determines the operating parameters of the battery in an awake state, stores these in digital form and/or supplies them to a digital interface output. The detection device is inactive in a sleep state and has a reduced consumption of electricity. A cut-off detection device compares the battery voltage with the predetermined cut-off voltage during the sleep state and awakens the detection device from the sleep state if the battery voltage falls below the predetermined cut-off voltage.

Abstract: A device for measuring a battery voltage is a self-calibrating device. The battery voltage is connected to a voltage divider formed of series-connected resistors, or components that are subject to a voltage drop. For the purposes of calibration the voltage divider is separated from the battery voltage and a reference current or reference voltage source is connected to the voltage divider in its place. The voltages dropping across the voltage divider are measured and an actual resistance ratio of the resistors of the voltage divider is calculated, based on the measured voltages. The voltage divider is then re-connected to the battery voltage that is to be measured and a battery voltage is determined with the aid of the voltage divider, taking into account the calculated resistance ratio.

Abstract: An operating strategy for the components of the drive train is defined as a function of data which characterizes a route to be traveled along. Depending on the operating strategy and the route data, expected energy consumption and a time period for which the energy can be made available are calculated. If the time period is detected as being sufficient, the drive train is controlled in accordance with the operating strategy. If the calculated time period is detected as not being sufficient, an alternative operating strategy is defined and the resulting time period is checked again.
