A light-emitting device includes a first pixel, a second pixel, and a third pixel. In the device, a component is provided for evaluating the degrees of ageing, each of which is associated with a distinct group, and for allocating, to the battery, in accordance with statistical distribution parameters of the evaluated degrees of ageing, a classification level that is representative of the potential performances of the battery during use. A reset logic module clears an output of the multiple-order integrator when the vehicle experiences a straight-driving condition, when a speed of the vehicle is less than a predetermined speed, andor when a sensor bias condition occurs. The slider member has a flat plate, a pressing portion perpendicular to the plate and a pair of latching arms extending from the plate. Each subtraction produces a possible remainder value, but only one subtraction will result in a valid remainder\u2014the one representing the divisor multiplied by the actual quotient that would result from the division operation\u2014and that remainder is then identified as the modulo output of the division operation.
