Abstract: An in-ground light, motion detector, or other active element is housed in a telescopically mounted housing so that it can be retracted to ground level when not in use and positioned above the ground when in use. A motor that extends and retracts the telescopically mounted housing relative to a main housing is rotatably mounted in a nonrotatable motor housing that adjoins the main housing.

A second plate having electrical contacts is nonrotatably secured to the motor housing so that relative rotation of the two plates activates and deactivates the motor. Relative rotation of the plates occurs when the telescopically mounted housing is fully extended or fully retracted because the rotational energy of the motor's output shaft is transferred to the motor when full extension or retraction has been achieved.

Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass.

These values are passed to pan and tilt controlling co-processors which control servo-motors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.

Abstract: A device and method of operation are disclosed which provide an improved light source. The device and its mode of operation serve to substantially reduce the energy required to produce sufficient light for normal human vision. A mechanical embodiment of the device serves to concentrate the total output of a light source into one or more relatively small beams, then sweep the beams of light around or over an area to be illuminated for vision. Alternatively, an electrical approach can be employed to achieve substantially the same results as the mechanical approach. Because the light emitted by the light source is concentrated within one or more relatively small beams, the intermittent lighting effect of which is undetectable by the human eye, a significant reduction in energy consumption can be achieved in that a lower-powered light source can be employed to achieve an illumination level which is comparable to that of a much higher-powered light source.

Abstract: A lamp for surgical illumination includes at least one reflector and at least one light source that are displaceable with respect to the one another by means for automatically adjusting the concentration of the light rays on an operating field.
