Abstract: The examples herein relate to assembly techniques and structures for sealing and lateral pressure compensation techniques that can be utilized in, for example, an electrowetting cell. The electrowetting cell can include a substrate that supports a well filled with a liquid. The electrowetting cell can include a control channel electrode to control the liquid via an electric field and a circuit connection to drive the control channel electrode. A seal is coupled to a spacer to seal the well between the substrate and the transparent cover. An expansion space, exterior to the well, is formed with the coupling of the seal and the spacer. As the liquid or the gas thermally expands or contracts, the seal compensates laterally by deforming sideways in an empty space of the expansion space.

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 example lighting device has a luminaire. The luminaire includes an illumination light source matrix including illumination light sources configured to be driven by electrical power to emit light rays for illumination lighting. The luminaire further includes an optical lens positioned and configured to extend over the illumination light source matrix and including an input surface coupled to receive incoming light rays emitted by the illumination light sources and an output surface. Both the input surface and the output surface each include various portions to refract or total internally reflect the incoming light rays emitted by the illumination light sources passing through to shape or steer the illumination lighting into an outputted beam pattern. A coupled illumination light source driver selectively controls the illumination light sources individually or in combination to adjust the outputted beam pattern from the optical lens.

Abstract: An example lighting device has illumination light sources, each configured to be independently driven. The device further includes an optical lens positioned over the illumination light sources. The optical lens has a number of aspheric or spheric convex surfaces, including an input surface and an output surface. The input surface includes an input peripheral portion and an input central portion. The input peripheral portion extends from the illumination light sources and curves from a region of the illumination light sources towards the input central portion. The input central portion curves towards the illumination light sources. The output surface includes an output lateral portion, an output shoulder portion, and an output body portion. Another example uses optical-to-electrical transducers, e.g. light detector or photovoltaic devices, in combination with the optical lens, for light reception transducer applications.

Each of the shafts has a beveled annular ring that makes stops the extension of the shafts from the stored position to the fully extended stored position. In the fully extended position, the successive sections form interlocking or interleaved joints.

Abstract: An exemplary system to provide visible lighting of a selectable spectral characteristic (e.g. a selectable color combination of light) uses an optical integrating cavity or other diffuse mixing element to combine light of different colors from different color LEDs. Amplitude modulation of pulsed operation the light sources, e.g. pulse amplitude modulation added to a baseline forward bias current for each of the LEDs, controls the amount of each light color supplied to the diffuse mixing element and thus the amount included in the combined light output of the system. A color sensor may provide feedback as to a color characteristic of the combined light, for closed-loop control of one or more of the pulse amplitude modulations. Examples are also disclosed that utilize phosphor doping of one or more of the system's reflective elements, to add desired wavelengths of light to the combined output.

Abstract: The invention provides a method and apparatus for pipelining the transformation of information between heterogeneous sets of data sources. The invention avoids intermediate data staging by constructing metadata that allow the acquisition of data in an order that matches the order in which the target data must be delivered. In a further feature of the invention, the acquisition, transformation, and delivery stages of an interface between two applications are pipelined as three processes that execute simultaneously on a continuous flow of data. Pipelining is a well-known technology that has been in use in operating systems, such as UNIX pipes and more recently by Torrent systems, to optimize the usage of multiprocessor machines. Uniquely, the invention applies pipelining technology to data transformation between heterogeneous data sources.

Abstract: A clutch-brake device having a housing, a shaft rotationally mounted therethrough, modular coupling units rigidly coupled to the shaft at either side of the housing, and an adapter which allows a single modular unit to be utilized interchangeably in either a clutch or a brake configuration. Each modular unit has a coupling member carrying an annular friction ring. The coupling member is rotationally connected to and spaced apart from a resilient disk defining a vacuum chamber therebetween. The resilient disk is rigidly attached to the modular unit and may be tapered towards the outer edge. The modular unit may also have several shims predisposed between the resilient disk and the coupling member which can be periodically removed to maintain the gap between the resilient disk and the annular friction ring within a preferred range. The device may have a microprocessor controlled high speed switch for controlling electromagnets which regulate engagement of the resilient disks.
