Abstract: An energy storage apparatus for storing energy transmitted by a power transmission line includes an elastically deformable component and an actuator-generator. The actuator-generator is coupled to the elastically deformable component such that electrical actuation of the actuator-generator generates tension in the elastically deformable component. The actuator-generator is further coupled to the elastically deformable component such that mechanical actuation of the actuator-generator via a release of tension in the elastically deformable component causes a generation of electrical energy by the actuator-generator.

Abstract: Embodiments of a search engine are disclosed that enable authors and third parties to influence the persistence and ranking of the author or the author's posts in search result listings using a bidding process or other compensation-based mechanism. In one embodiment, the search engine allows authors to submit bids in auction for ranking in order to keep their posts (or posts of other authors) visible to targeted searchers for a longer period of time than would normally be available. The bid amount, together with other attributes, can be used to determine the relevance and ranking of posts or authors provided in a search results page to a searcher. Embodiments of the search engine may be utilized with a microblogging service or a social networking service.

Abstract: An apparatus for removing harmonic noise from a power transmission line transmitting electricity at a primary frequency includes a filter and a controller coupled to the sensor and to an actuator-generator. The filter separates electricity at a harmonic of a primary frequency from the electrical signal transmitted by the power transmission line. The controller is configured to modulate consumption of electricity from the power transmission line. The consumption is controlled by electrical actuation of the actuator-generator, such that the electrical actuation of the actuator-generator causes consumption of electricity from the power transmission line at a harmonic of the primary frequency. The actuator-generator is coupled to an elastically deformable component, such that electrical actuation of the actuator-generator generates tension in the elastically deformable component.

Abstract: Wind screens for reducing wind loading on one or more solar collectors are disclosed. The wind screens move with the solar collector as the collector tracks the sun in one or more dimensions. The wind screen pivotably connects to at least one solar panel of the collector. Another side of the wind screen may connect to the ground or to an adjacent collect, thus serving to divert wind over the collector. Wind screens may be made of various materials including rigid, flexible, or elastic materials and can change position, orientation, and/or effective length as the one or more collectors track the sun from East to West.

Abstract: The invention is generally related to the systems and methods through which household appliances can provide intuitive and enhanced interactivity through visual inputs. In particular, the disclosure presents methods relating to control of a household appliance, such as a microwave or a refrigerator, via recognition of visual indicia, such as graphics, text, and the like, using a visual sensor such as a camera.

Abstract: A tracking concentrator with a positioning system for alternately aiming the tracking solar concentrator based on the sun or a database is disclosed. The preferred positioning system comprises a sensor adapted to detect an incident light level; a tracking database comprising solar angle information; an orientation processor; one or more actuators for aiming the one or more optical elements based on the orientation processor; wherein the orientation processor is configured to track the sun based on (a) the receiver if the sensed light level exceeds a determined threshold, and (b) the tracking database if the sensed light level does not exceed the determined threshold.

Abstract: Methods, computer readable media, and apparatuses for providing user interfaces, determining screen layouts, and displaying microblog posts are presented. A microblog client may receive a set of microblog posts and provide a user interface for displaying the received microblog posts. The microblog client also may parse the received posts and identify one or more content elements within the posts. The microblog client may then download additional information based on the content elements, and may determine a screen layout for displaying the posts based on the content elements and the additional downloaded information. In certain examples, microblog posts may be parsed and the additional related information may be downloaded prior to the selection of the posts in the user interface. The determination of a screen layout for displaying the microblog posts may also depend on the display characteristics, for example, screen size or orientation of a client device.

Abstract: The invention in the preferred embodiment features a solar concentrator that can align and/or track based on images from a video camera, for example. The concentrator preferably includes one or more optical elements for directing light to a receiver, a camera for capturing an image of the optical elements, and a controller configured to: detect the orientation of the one or more optical elements from the one or more images, determine an orientation error based on the detected orientation, and automatically orient the one or more optical elements to minimize the orientation error. The optical elements generally comprise a plurality of mirrors or lenses arranged in a one or two dimensional array.
