Abstract:
A shield-can includes a shield member defining a perforated portion to form a peripheral frame and a top plate, the top plate is enabled to be separated from the peripheral frame.
Abstract:
An informative priors image search result summarization system and method that summarizes image search results based on the image relevance (as determined by a search engine's initial ranking) and the image quality. Embodiments of the system and method cluster the image search results, rank images within each cluster based on a computed image score, and then select a summary image for the cluster. Each cluster is analyzed and an image in the cluster having the maximum image score is included in a selected summary collection. The image score is computed using the image relevance and the image quality, as well as a cluster coherence, a density, and a diversity. The selection of images from a collection of candidate images generates an image search result summarization, which is presented to a user. The summaries are presented to the user in a ranked order based on their image scores.
Abstract:
An annular device includes an annular main body, a battery mounting portion, and a battery cover. The battery mounting portion protrudes from an inner surface of the main body, and includes a first arcuate element and a second arcuate element opposite to each other. The battery cover is operable to clasp the battery mounting portion, and includes a first arcuate member and a second arcuate member opposite to each other. The first arcuate member clasps the first arcuate surface, and the second arcuate member clasps the second arcuate surface.
Abstract:
A data warehouse that operates to receive a spatial query and return a spatial result for the spatial query, the data warehouse comprises a regular database operating to receive and process a regular query and return a query result in response to the regular query. The data warehouse also comprises an interface layer implemented external to the regular database and operating to intercept the spatial query and translate the spatial query into the regular query for processing by the regular database. The regular database includes at least one spatial index that is accessed by the interface layer to translate the spatial query into the regular query for processing by the regular database.
Abstract:
For use with an asymmetrical half-bridge power converter having a primary switching circuit coupled to a primary winding of a transformer and a rectifier coupled to a secondary winding of the transformer, a reverse recovery circuit a method of operation thereof. In one embodiment, the reverse recovery circuit includes an inductor that reduces current spikes in the primary switching circuit caused by a reverse recovery phenomenon associated with the rectifier. The reverse recovery circuit also includes a diode, coupled to the inductor, that clamps a voltage across the rectifier.
Abstract:
A module mount for use in electrically and mechanically mounting an encapsulated power rectifier module, having a plurality of rigid leads protruding from a major mounting surface thereof, in an orientation in which the major mounting surface is substantially normal with respect to a substantially planar circuit board. In one embodiment, the module mount includes (1) a substantially planar substrate having a plurality of apertures located to register with the plurality of rigid leads and (2) a plurality of power conductors, associated with the plurality of apertures, that electrically couple the plurality of rigid leads to an edge interface on the substrate, the edge interface adapted to be coupled to the circuit board.
Abstract:
In a power converter having a power train that includes a power switch and a rectifier for conducting forward currents from the power switch, a circuit for, and method of, reducing switching losses associated with the power train. The circuit includes: (1) an auxiliary switch and an inductor coupled to the power train that reduce a switching loss associated with the power switch and (2) an impedance element series-coupled to the rectifier that reduces a change in current through the rectifier thereby decreasing a reverse recovery current flowing therethrough.
