A projection-type image display device includes a light source, a phosphor, a filter, and a filter driver. The light source emits blue illumination light. The phosphor generates yellow illumination light, which includes red illumination light and green illumination light from a part of the blue illumination light, and reflects the blue illumination light and the yellow illumination light. The filter reflects the blue illumination light, which is reflected by the phosphor, toward the phosphor, and transmits the yellow illumination light therethrough. The filter driver controls the reflection amount of the blue illumination light toward the phosphor by controlling the insertion amount of the filter onto the optical path of the blue illumination light. The phosphor generates yellow illumination light also from the blue illumination light reflected by the filter.

The disclosure relates to a light source apparatus including a solid-state light source, a phosphor on which light emitted from the solid-state light source is incident, an optical system that guides the light emitted from the solid-state light source at least to the phosphor, an enclosure member having a first accommodation space that accommodates the phosphor and a second accommodation space that accommodates the optical system, and an air blowing mechanism that blows air into the first accommodation space, wherein the optical system includes a pickup lens on which fluorescence emitted from the phosphor is incident, and the first accommodation space and the second accommodation space are separated from each other by a holding member that holds the pickup lens.

A holster broadcasts a message indicating that a weapon has been removed from the holster. A recorder, in response to authenticating the message, controls recording of audio and video. The message may include an identifier of the holster. The recorder may maintain a white list of identifications and ignore messages with identifications that are not on the white list. The message, instead of being broadcast, may be transmitted with an address of an intended recorder.

The description relates to remote collaboration via a telepresence experience. One example can include an interactive digital display. The example can also include a virtual user presentation component configured to generate a graphical user interface that includes a virtual representation of a remote user on the interactive digital display. The graphical user interface can be configured to present the remote user in a side by side or mirror image relationship to a local user of the interactive digital display.

Systems and methods for reconstructing an object boundary in a disparity map generated by a structured light system are disclosed. One aspect is a structured light system. The system includes an image projecting device configured to project codewords. The system further includes a receiver device including a sensor, the receiver device configured to sense the projected codewords reflected from an object. The system further includes a processing circuit configured to generate a disparity map of the object, detect a first boundary of the object in the disparity map, identify a shadow region in the disparity map adjoining the first boundary, the shadow region including pixels with codeword outages, and change a shape of the object in the disparity map based on the detected shadow region. The system further includes a memory device configured to store the disparity map.

A method and system for generating light pattern using reflective polygons are provided herein. The method may include: rotating at least one polygon having a plurality of reflective facets along a rotation axis parallel to the facets; transmitting a light beam on the facets of the polygon; tilting the light beam relative to the polygon in parallel to the rotation axis so that the light beam hits each of the facets at a different tilt angle, thereby producing a light pattern comprising a plurality of lines; and controlling at least one of: the light intensity, the rotating, and the tilting, so as to produce an adjustable light pattern transmitted at a scene.
