摘要:
A weighing scale, e.g. a top-pan scale, having a scale pan (01, 02) supported on a force transducer, and a corner load sensor (03, 04, 06, 08, 09) measuring the tilting of the scale pan (01, 02) relative to the force transducer. The corner load sensor includes a light beam source (03, 04, 06) emitting a first light beam and a second light beam. The first light beam and the second light beam are directed toward a reflecting surface on an underside of an arrangement that includes the scale pan (01, 02). The first light beam and the second light beam are respectively inclined relative to the reflecting surface of the untilted scale pan (01). The corner load sensor (03, 04, 06, 08, 09) of the scale also includes a first optical sensor (08) measuring the first light beam reflected by the reflecting surface. If no corner load exists, a predetermined proportion (12) of the reflected first light beam is directed to the first optical sensor (08). If the scale pan (02) is tilted, the proportions of the reflected light beams which fall on the two optical sensors (08, 09) change. The corner load sensor (03, 04, 06, 08, 09) has an evaluating unit determining the tilt of the scale pan (01, 02) dependent on the light quantities measured with the two optical sensors (08, 09).

摘要:
The invention relates to an electronic control device for a vehicle, further to a system for activating program functions thereof, and to a corresponding method for the same. The invention allows subsequent activation, optionally at a cost, of program functions, particularly allowing commerce in such program functions. To this end, an electronic control device (2) for a vehicle (1) is provided, having an interface device for connecting to a data line (3), wherein the electronic control device comprises a plurality of program functions for performing control and regulating tasks in the vehicle, and at least a partial quantity of program functions can be deactivated, such that the electronic control device does not execute a deactivated program function, even if there is a corresponding need for control and regulating, wherein the electronic control device is set up for receiving and analyzing encoded activation information and, upon presentation of valid activation information, activates an associated program function that can be deactivated.
