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.

The present disclosure provides engineered surfaces that exhibit reduced specular reflection and gloss while still providing a high intensity of reflected light at multiple incident angles. The structured metal surfaces include engineered topography that increases diffuse reflection, leading to a greater intensity of light perceived at multiple viewing angles. A viewer engaging such surfaces is likely to perceive a stronger white reflection of the incident light and an improvement, particularly in orthodontic and other oral applications, of aesthetic appearance. Methods of creating the engineered surfaces and orthodontic articles incorporating the engineered surfaces are also disclosed.

An optical module includes: first and second optical elements; third and fourth optical elements; a first polarization control element and a first reflective light modulator that are sequentially arranged in one of a positive direction of a first vector and a negative direction of a second vector from the second optical element; a second polarization control element and a second reflective light modulator that are sequentially arranged in one of a negative direction of the first vector and a positive direction of the second vector from the third optical element; and a sliding mechanism that relatively moves the first and second optical elements and the third and fourth optical elements in the direction of the first vector relative.

An method for characterizing a modulator for fabricating a silicon photonics circuit and an apparatus (e.g., a silicon photonics wafer) made via the method are described. The method includes determining an absorption spectrum of a modulator and determining, based at least on the determined absorption spectrum, an operational bandwidth of the modulator. The method further includes selecting a laser for coupling with the modulator using the operational bandwidth of the modulator. In this way, the laser is selected such that it has an emission bandwidth that corresponds to the operational bandwidth of the modulator.

A mechanical chameleon through dynamic real-time plasmonic tuning, the external surface of which is covered by plasmonic cells is provided. Plasmonic cells, based on the combination of bimetallic nanodot arrays and electrochemical bias, use the electrochemical method elctrodepositing and stripping Ag shells on plasmonic Au nanodomes and then we achieve the reversible full color plasmonic cells/display. Plasmonic cells, under the control of circuits and sensors, make mechanical chameleon automatically change the color of its own when it's walking to the corresponding background color and always keeping the same color with the color background. This mechanical chameleon through dynamic real-time plasmonic tuning can capture and simulate the entire color-patterns of the environment and then drive the color-changing process in individual cells, fully merging the mechanical chameleon into the surroundings, which makes this technology is readily approachable.
