Abstract: A linear lighting device may include an elongated housing that defines a cavity. The linear lighting device may include plurality of emitter printed circuit boards configured to be received within the cavity. Each of the plurality of emitter printed circuit boards may include a plurality of emitter modules mounted thereto. Each of the plurality of emitter printed circuit boards may include a control circuit configured to control the plurality of emitter modules mounted to the respective emitter printed circuit board based on receipt of one or more messages. The linear lighting device may include a total internal reflection lens for each of the plurality of emitter printed circuit boards. The total internal reflection lens may be configured to diffuse light emitted by the emitter modules of the plurality of emitter printed circuit boards.

Abstract: Various shaped abrasive particles are disclosed. Each shaped abrasive particle includes a body having at least one major surface and a side surface extending from the major surface.

Abstract: A digital display of an active window is provided. An application, separate from the application providing the digital display, is capable of identifying an artifact in the active window of the digital display without a priori knowledge or an application programming interface to the application providing the digital display. The artifacts may be alpha-numeric artifacts or non-alpha-numeric artifacts. The active window may be examined in multiple dimensions including 2 dimensions, 3 dimensions or more. Alpha-numeric artifacts, once identified, are pre-processed to remove anti-aliasing to allow for processor optical recognition.

Abstract: An anti-polish ring for an internal combustion engine is provided. The anti-polish ring includes an axially extending ring portion that is configured to scrape a top portion of a piston in a cylinder liner. The anti-polish ring is configured to accommodate passage of an intake or exhaust valve thereby. The anti-polish ring may include an alignment feature so that the anti-polish ring is inserted in a predetermined orientation in the cylinder. The anti-polish ring may include a heat shield and/or a seating member.

Abstract: An attitude control system for spacecraft having thrusters utilizes the exhaust plume of the thrusters for attitude control. At least one of the thrusters is canted so that its reaction line of thrust, when misaligned with one of the spacecraft's primary axes; causes a control torque to develop about said axis which aids the plume torque about said axis resulting from the plume of the one thruster impinging on a surface such as that of a solar panel on the spacecraft.
