    摘要: A control device for controlling charging of a rechargeable battery, the control device being configured to: determine the voltage of the battery during charging of the battery, stop charging, when the determined voltage exceeds a predetermined upper voltage limit, determine the voltage of the battery after stopping charging, determine the voltage difference between the predetermined upper voltage limit and the determined voltage of the battery after stopping charging, and continue charging, when the determined voltage difference exceeds a predetermined threshold. A corresponding method controls charging of a rechargeable battery.

    摘要: An optical rangefinder based on time-of-flight measurement, radiates pulsed light toward an object (70), and receives reflected light from the object, the receiver operating in a photon counting mode, so as to generate a pulse for a detected photon. There is a variable probability of a photon detection on the receiver, and a controller (370, 380, 390; 365, 470, 475, 380, 390; 570, 580, 590, 390) controls the photon detection probability of the receiver, based on a light level. By controlling the detection probability according to a light level, the receiver can have an increased dynamic range, and without the expense of using optical components. This can apply even while detecting very weak signals since the receiver can still be in a photon counting mode while the detection probability is controlled. The light level can be indicated by an output of the receiver itself, or by another detector external to the receiver.
