Abstract: A surgical lamp for illuminating a surgical field on a human body is provided. The surgical lamp comprises a control device (4), a lamp body (1) comprising several illuminants (3) with one respective light ray (I, II, II?) directed to the surgical field, and a 3D sensor (6) for detecting a spatial position of at least one object, and a device for switching on and off and dimming the illuminants (3), wherein the control device (4) controls the devices for switching on and off and dimming the illuminants (3), the 3D sensor (6) detects the spatial positon of the at least one object and transmits corresponding data to the control device (4), and the control device (4) is configured to control the illuminants (3) according to the spatial position of the at least one object.

Abstract: A coaster for illuminating a liquid receptacle is disclosed. The coaster includes a light and a pressure-sensitive switch for activating the light when the receptacle is placed on the coaster so as to illuminate the receptacle and its contents. A disc battery is sandwiched between strips of a flexible circuit board so that compression of the strips against the battery causes a completion of the circuit to turn the light on.

Abstract: A control device (2), for a medical apparatus, having at least one sensor (5) for three dimensionally detecting an object (8) which is configured to render graspable a vector (10) for a direction by its alignment is provided, wherein the object (8) is directed to a target area, and the vector (10) generates an intersection point with a surface of the target area. The control device (2) is adapted to recognize in which target area the intersection point is located and to actuate a predefined action for the target area by the medical apparatus.
