In case of a radio link, a video-transmitting radio unit of the remotely controlled device provides a digital video feed over the radio link to a video-receiving radio unit of the operator control unit, and in so doing the remotely controlled device adapts the resolution and/or frames per unit time of the video feed based solely on measurements made by the remotely controlled device, measurements indicative of the quality of the radio link.

Abstract: A vehicle headlamp using a high-power LED light source, receiving power regulated by a driver circuit, is mounted in a housing and covered at least in part by a light transmissive cover using a construction by which heat developed by the driver circuit (current regulator) is conducted to the light transmissive cover, thereby heating the transparent cover and so retarding the formation or accumulation of ice and snow on the light transmissive cover.

Abstract: A vehicular headlamp system and corresponding kit, including (left and right) headlamps and a mode switch (control mechanism) responsive to inputs from a mode switch console or other user interface arrangements, the combination of headlamps and mode switch providing high and low beam on-road illumination and a higher level of illumination for off-road illumination using the same light source in each headlamp as is used for the on-road illumination. Cooperation between a light source driver circuit in each headlamp and the mode switch results in the light source in each headlamp being driven by more or less current, as required by the selected mode. A (daytime) running lights mode of operation may also be provided using the same light source.
