A through-beam multi-digit dry meter is disclosed, wherein a lower and an upper holding plate are fastened together; two brackets are integrally connected on the lower holding plate. A 180° curved frame is between the brackets, on which is a flexible printed circuit. Engagement holes are in the brackets. A light-transmitting hollow character wheel shaft is in the engagement holes. Character wheels are on the light-transmitting hollow character wheel shaft and made of light-transmitting material. On the left and/or right side of a character wheel, short black strips are stamped. Long black strips are stamped on the character part of the character wheel head to tail, on which numbers are printed. The meter enables direct reading of three to eight character wheels to measure gas, electricity of water of large flow within the national standard limitation, which is easy to produce and assemble and saves the cost.

Provided is a photoelectric sensor capable of enhancing display flexibility of a display section mounted on the photoelectric sensor and making this display flexibility contribute to improvement in user's operability. In a Run mode, a current value is displayed in large-sized numerals on a display section. When switching is made from the Run mode to a setting mode and letter information is to be displayed in the setting mode, a current value is displayed in relatively small-sized numerals at the corner (e.g., lower left) of the display section.

An A/D converter includes an A/D conversion unit and an output unit. The A/D conversion unit includes a second A/D converter (successive approximation register A/D converter) and generates first digital data having a first number of bits and second digital data having a second number of bits, where the second number of bits is smaller than the first number of bits. The output unit provides first output information that is the first digital data and also provides second output information based on the second digital data. The output unit provides the second output information before providing the first output information.

A device and method for increasing the range of a vehicle, which is driven by an electric motor and a high-voltage battery, include an electronic control unit which is programmed such that on the basis of the high-voltage battery charge state, which is continuously estimated in an updated manner, a corresponding remaining range is displayed to the driver. A lower charge state limit is defined, which is associated with a remaining range to be displayed of null when the charge state is estimated in an error-free manner. The lower charge state limit is associated with a defined first minimally permissible cell voltage limit. During a driving operation, it is determined whether a greater range is being displayed than what can be demanded on the basis of the current charge state due to an estimation error. The display is not corrected by the estimation error difference. And, an emergency mode is automatically activated if an estimation error has been detected, wherein the cell voltage is reduced below the first cell voltage limit in the emergency mode.
