Rapid serial visual presentation techniques for consumer digital video devices

Abstract: In this paper we propose a new model for a class of rapid serial visual presentation (RSVP) interfaces [16] in the context of consumer video devices. The basic spatial layout "explodes" a sequence of image frames into a 3D trail in order to provide more context for a spatial/temporal presentation. As the user plays forward or back, the trail advances or recedes while the image in the foreground focus position is replaced. The design is able to incorporate a variety of methods for analyzing or highlighting images in the trail. Our hypotheses are that users can navigate more quickly and precisely to points of interest when compared to conventional consumer-based browsing, channel flipping, or fast-forwarding techniques. We report on an experiment testing our hypotheses in which we found that subjects were more accurate but not faster in browsing to a target of interest in recorded television content with a TV remote.

Rotor of permanent magnet embedded motor, blower, and compressor

Abstract: A rotor of a permanent magnet embedded motor includes a rotor iron core formed by stacking a predetermined number of magnetic steel sheets punched into predetermined shapes, a plurality of permanent-magnet insertion holes formed along an outer circumferential portion of the rotor iron core and each including permanent-magnet end-portion cavities on its both ends, a plurality of permanent magnets inserted into the permanent-magnet insertion holes, and a plurality of slits formed in the outer-peripheral side iron core portion outside of each permanent-magnet insertion holes, wherein a distance between a first slit present in a radial direction of each of the end portions of the permanent magnets and a second slit, which is adjacent to the first slit and closer to the center of its magnetic pole, is smaller than a distance between those slits other than the first and second slits.

An Intelligent Load Flow Engine for Power System Planning

Abstract: An intelligent load flow engine is an expert system embedded in the personal workstation that is used by the power system planners. The objective of the engine is to provide both an expert and novice user with a friendly working environment, aiming at enhancing a user's creativity in making operational plans. To this end, the personal scientific workstation that was developed for power system planning is equipped with an expert system whose knowledges are acquired from the experienced power system planners. This paper describes the detail of the intelligent engine, and shows how the load flow planning is assisted with an expert system.

Cellular radio telephone enhancement circuit

Abstract: For use in a cellular radio-telephone system to enhance a signal from a cell site in an area shadowed by an obstruction such as a building or a mountain or the like, and to receive signals from subscribers in such areas, a cell enhancer includes bidirectional receivers, transmitters and amplifiers, the receivers and transmitters both including duplexer circuits for coupling signals in the proper up-link and down-link bands to the proper up-link and down-link antennas for transmission. Two embodiments of amplifiers are disclosed. A wideband amplifier network includes an input duplexer, a wideband amplifier with an attenuator, and an output duplexer, the duplexers coupling signals from both the up-link and down-link duplexer circuits to the amplifier for amplification. A narrow band network includes a plurality of amplifier modules each of which amplify only on one up-link and down-link channel assigned to the cell. A signal divider couples signals in the appropriate channels to the inputs of the corresponding modules, and a signal combining circuit receives signals from the modules to generate a composite signal for transmission by the up-link and down-link antennas. The enhancer further includes a control circuit responsive to signals from the cell site received through the amplifier for controlling the operations of the enhancer and for reporting to the cell site the status of the enhancer by transmitting signals through the enhancer.
