Abstract: This disclosure relates to a surgical lighting device comprising a shell (12), a plurality of light sources (24) coupled to the shell, and a closure plate (18) for closing the lighting device by allowing light to pass through. The closure plate comprises a plurality of lens elements, each lens element being configured to collect and focus light from a corresponding light source to generate a light spot of a predetermined diameter located at a predetermined distance from the lighting device. In order to simplify the structure of the lighting device, the light sources and the cover plate are arranged in such a way that the light beams coming from the light sources and received by the associated lens elements arrive at the lens elements without substantial reflection or deflection. The closure plate therefore comprises all the optics necessary for collecting and focusing the light from the light sources.

Abstract: A medical lighting device for illuminating an operative field, which device includes light-emitting diode (LED) light sources that cooperate with collimator optical systems to light the operative field. LEDs are mounted on a flat printed circuit board so that their illumination axes (B) passing through the collimator optical systems (7) have different angular orientations. The printed circuit board (6) may be cut out to form tongues, each of which is flexible and has a free end carrying an LED. Each tongue can be deformed under stress in such a manner that its free end is oriented substantially perpendicularly to the illumination axis (B).

Abstract: A grouser assembly is selectively attachable to an endless track having a carcass, side edges and traction lugs. The grouser assembly includes a body having top and bottom faces. The body includes a recess defined in the bottom face that is shaped to receive a traction lug of the endless track. The grouser assembly further includes ground-contacting projections connected to the body and extending away from the top face, and first and second attachment assemblies connected to the body. The second attachment assembly has an attached configuration and a released configuration, and is positioned relative to the first attachment assembly such that when (i) the traction lug is received in the recess, (ii) the first attachment assembly attaches the grouser assembly to the carcass, and (iii) the second attachment assembly is in the attached configuration, the second attachment assembly attaches the grouser assembly to the endless track.
