Abstract: A high frequency high power converter system comprises: a plurality of resonant tank circuits arranged in parallel, a plurality of transformers, each transformer having a single primary winding and a plurality of secondary windings, and a vacuum electronic device, the output of each resonant tank circuit being applied to a respective different transformer and the outputs of the transformers being arranged to drive the vacuum electronic device.

Abstract: Recommending fonts includes obtaining a product category and determining whether a font recommendation should be made. In the event that the font recommendation should be made, the technique further includes determining a recommended font that corresponds to the product category, the determination being based at least in part on a plurality of predetermined correspondences, the plurality of predetermined correspondences indicating associations between a plurality of product categories and a respective plurality of fonts, and outputting information pertaining to the recommended font.

Abstract: A method of synchronizing the display of instant messages between multiple clients is performed at a computer system. Upon receipt of a first synchronization request from a client, the first synchronization request including a conversation identifier and a last message timestamp, the computer system identifies a conversation including a set of messages associated with the conversation identifier. The set of messages was generated after the last message timestamp and have not been received by the client. The computer system then assigns display parameters to the set of messages based on their read-or-not indicators, content, and their temporal relationship with other messages in the conversation. Next, the computer system sends the set of messages and their respective display parameters to the client in a reverse chronological order. The client then displays the set of messages in accordance with their respective display parameters.
