Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that determine whether to illuminate a scene with electromagnetic radiation at a first wavelength or electromagnetic radiation at a second wavelength. An illuminator that is configured to selectively emit electromagnetic radiation at the first wavelength and at the second wavelength is triggered to emit electromagnetic radiation at the first wavelength instead of the second wavelength. A first voltage is applied to a first electrically active filter. A third voltage is applied to a second electrically active filter. A first image is obtained from a first sensor that senses electromagnetic radiation that passes through the first filter. A second image is obtained from a second sensor that senses electromagnetic radiation that passes through the second filter. A depth map is generated from the first image and the second image.

There are provided green-emitting quantum dots (QDs) including I-III-VI type ternary CuGaS core QDs and ZnS multishell wherein Cu:Ga is 1:10 to 1:1, and a fabricating method thereof. Integration of these QDs and red-emitting QDs into a blue LED leads to the fabrication of a white light-emitting device with high color rendering index. There are also provided blue-emitting QDs including I-III-VI type quaternary ZnCuGaS or CuGaAlS core QDs and ZnS multishell, and a fabricating method thereof. An electrically-driven blue light-emitting device with a QD emitting layer including these QDs interposed between a hole transport layer and an electron transport layer is fabricated.

Example systems and methods to transform events and/or mood associated with playing media into lighting effects are disclosed herein. An example apparatus includes a content identifier to identify a first event occurring during presentation of media content at a first time. The example apparatus includes a content driven analyzer to determine a first lighting effect to be produced by a light-producing device based on the first event and instruct the light-producing device to produce the first lighting effect based on the first event during presentation of the media content. The content identifier is to identify a second media event occurring during presentation of the media content at a second time after the first time. The content driven analyzer is to instruct the light-producing device to one of maintain the first lighting effect based on the second event or produce a second lighting effect based on the second event during presentation of the media content.
