    Abstract: A light fixture includes a housing having sidewalls that define a manifold aperture, extending from upper to lower edges of the manifold aperture. The housing includes first coupling features. The light fixture includes at least one adapter plate with second coupling features that removably couple with the first coupling features. The adapter plate defines an adapter plate aperture. At least one light emitting engine removably couples with the adapter plate such that emitted light passes through the adapter plate aperture. The light fixture further includes a baffle that includes at least one baffle cell. The baffle cell includes an upper baffle edge that defines: an upper baffle aperture through which light emitted by the light engine passes, a lower baffle edge that defines an output aperture for the emitted light, and a baffle cell wall that extends from the upper baffle edge to the lower baffle edge.

    Abstract: A control pod includes a controller to control an environmental condition in a space, and a cover plate covering the controller and having a light transmissive area extending along a substantial section of an outer perimeter of the cover plate. Programming configures a processor to detect user inputs of a control command based on a user action detected via user input response sensors, and based on the detected control command, send a control signal to a device to implement a function corresponding to the detected control command. The processor also controls a light source to selectively provide a light output through the light transmissive area of the cover plate for a period of time following the control command detection, as visible feedback corresponding to the detected control command, for observation by the user, along at least a portion of the section of the light transmissive area of the cover plate.

    Abstract: A system comprises a driver and an electrowetting cell controlled by the driver that includes a substrate that includes a well filled with at least two non-mixing media. The well has lateral walls and a stepped control channel electrode matrix including multiple stepped control channel electrode arrays. The lateral walls can collectively form a continuous perimeter around the well (e.g., circle shaped). Each stepped control channel electrode array includes a number of stepped control channel electrodes formed at different longitudinal levels along a respective lateral wall. Each stepped control channel electrode is independently controllable to control a shape of the at least two non-mixing media via an electric field. Each lateral wall encloses the at least two non-mixing media inside the well.

    Abstract: An electrowetting cell includes a substrate that includes a well filled with at least one fluid an external contact surface. The substrate is formed of ceramic or fiberglass mesh infused with resin. A control channel electrode connection pad and a common electrode connection pad are on the external contact surface. A first plate is coupled to the substrate to seal a first end of the well. A second plate is coupled to the substrate to seal a second end of the well. The electrowetting cell further includes a control channel electrode on the substrate configured to control a shape of the at least one fluid via an electric field, a common electrode, a control channel electrode interconnect connected to the control channel electrode and the control channel electrode connection pad, and a common electrode interconnect connected to the common electrode and the common electrode connection pad.
