Abstract: The present disclosure describes an insulative baffle comprising a shell material and a liner material are spaced apart to define a baffle cavity. The cavity is populated with a plurality of three-dimensional (3D) insulative structures. Each 3D structure is formed as a unitary frame made up of multiple interconnected struts. The arrangement of these struts defines apertures between them, and the frame collectively encloses an internal cavity. Because each 3D structure is a discrete, resilient body, the plurality of such structures provides structural support that maintains separation between the shell and liner materials and allows the baffle to loft and recover after compression. At the same time, the shape, distribution, and hollow nature of these frames trap air and impede heat transfer, so the 3D structures not only hold the baffle open but also actively contribute to the insulative performance of the baffle without relying on loose fibers or down.

Abstract: Methods and systems are described for adjusting an optical signal. An example device can comprise a plurality of waveguides. The device can comprise an interference structure optically coupled to the plurality of waveguides and configured to receive an optical signal and distribute the optical signal to the plurality of waveguides as a plurality of optical signals. The device can comprise a plurality of phase shifters coupled to corresponding waveguides of the plurality of waveguides and configured to adjust the phase of one or more of the plurality of optical signals. The device can comprise a plurality of emitters optically coupled to corresponding outputs of the plurality of phase shifters and configured to output the adjusted plurality of optical signals. The adjusted plurality of optical signals can be output as light patterns reconfigurable in at least one dimension.
