Patent Images
1. A device comprising:
- an illumination component to illuminate at least a portion of an environment;
a projector to project images onto a surface of the environment, the projector comprising;
a light source;
a micro-mirror device that includes a plurality of micro-mirrors, wherein light from the light source is reflected, at least in part, by one or more of the plurality of micro-mirrors to project an image onto the surface, anda motor coupled to the micro-mirror device, the motor configured to rotate the micro-mirror device such that the image projected onto the surface is correspondingly rotated; and
a time-of-flight sensor to receive at least a portion of light from the illumination component scattered by the environment, the time-of-flight sensor configured to determine a time of flight value associated with one or more objects in the illuminated portion of the environment, wherein the motor is further configured to rotate the time-of-flight sensor.

Abstract
A device includes a projector to project an image onto a surface. The projector includes a micro-mirror device comprising an array of micro-mirrors. Light from a light source is reflected by one or more of the array of micro-mirrors, to project the image onto the surface. In one implementation, the micro-mirror device is rotated to correspondingly rotate the projected image on the surface. In one implementation, the device is housed in a table lamp.

10. A system in a structure comprising:
-
a light source; a micro-mirror device comprising a plurality of micro-mirrors, wherein one or more of the plurality of micro-mirrors are configured to reflect at least a portion of light from the light source to project an image onto a surface in an environment; a rotation arrangement configured to rotate the micro-mirror device such that the image projected onto the surface is correspondingly rotated; and a time-of-flight sensor configured to determine values associated with distances to one or more objects in the environment, the time-of-flight sensor configured to receive light reflected from the one or more objects in the environment along an optical path in the structure shared in common with light reflected by the one or more of the plurality of micro-mirrors from the light source. - View Dependent Claims (11, 12, 13, 14, 15, 16)
