Abstract: A bi-directional solid state switch has two main transistors which are connected to each other with input to input and input referenced output to input referenced output. Each unreferenced transistor output is separately connected to an output terminal of the switch. An electrical impedance is connected between the input connection and the input referenced output connection. A driver signal is connected across the input connection and one output terminal. This circuit topology is counter-intuitive, but provides advantages which can include eliminating the need for electrical isolation, being capable of turning on or off at any time, at or between zero crossings, having a high speed of response, simplicity, reliability, cost-effectiveness, and energy-efficiency.

Abstract: The present invention relates to a new catalyst system for fluorous biphasic catalysis processes which comprises functionalized polymeric beads, monodisperse SiO2 or SiO2 flakes associated with the catalyst. These functionalized particles are used as a support for catalysts in fluorous biphasic catalysis (FBC).

Abstract: A method and system for automatically estimating budget items based on past transactions and generating a cash flow forecast for one or more accounts. A budget item is determined for each of a plurality of categories of transactions. A frequency and amount of each budget item is determined as a function of an actual transaction count, a date span of actual transactions, and a sum of actual transaction amounts—all of the transactions occurring in the past. For each budget item, a cash flow transaction is determined as a function of a posting date criterion and a selected forecast period. A running balance of the cash flow transactions is determined and displayed. Through the display, a user is enabled to modify individual cash flow transactions to generate a new cash flow forecast, or generate an alternate cash flow forecast that can be compared to the original cash flow forecast.

Abstract: A system and method for dynamically displaying data items on a client computer. In one aspect of the invention, the client computer displays a graphical user interface having a windowing environment and a desktop. The desktop includes a ticker display pane for dynamically displaying the data items. The data items may contain hyperlinks so that a user has access to information on multiple server computers. The data items are displayed in a substantially continuous sequence and may be provided from Internet servers, Intranet servers, LAN servers, and/or the client computer itself.

Abstract: A dual band antenna is described which comprises a single band antenna surrounded by single band antenna elements. For example, the single band antenna may be a horn operating at a first frequency band and the single band antenna elements may be a flat plate array. In this case, the flat plate array contains an aperture through which the horn extends. The single band antenna and single band antenna elements are positioned such that a transmit and a receive antenna beam are created which have approximately equal phase centres and beamwidths. The single band antenna may also be an array of antenna elements, such as a flat plate array. Alternatively the single band antenna may be formed from dipole elements. As well as this the single band antenna elements may be dipole elements, flat-plate elements or any other suitable type of elements. The dual band antennas described may be used as feeds for reflector antennas or as antennas in their own right.

Abstract: A demolition-leverage tool including a straight tube or pipe handle connecting at the base of the tube or pipe to a prying member attached at a right angle to the handle, a pivot bar attached at the base of the pipe handle where it intersects with the prying bar, disposed crosswise thereof, is a pivot bar being in operative juxtaposition to the prying member to serve as an off-center pivot point in relation to the prying member and when a force is applied to the handle portion of the tool, the demolition-leverage tool also has a detachable pad that connects to the pivot point of the tool, therefore allowing the tool not to sink into soft earth while the prying bar in underneath an object and sufficient force is applied to the handle as to raise the item underneath the prying bar.

Abstract: A technique is used by a squelch circuit (200) that generates a fast squelch. The technique involves generating a noise signal (211) from a demodulated signal (105), generating a squelch check request (405) of one of two types, performing a release (410) of a reset control (107) in response to the squelch check request, generating an integrated noise signal (106) having essentially no decay rate from the noise signal starting at the release of the reset control, generating a result of a comparison (815, 860) of the integrated noise signal to one of two values corresponding to the one of two types of squelch check requests at an expiration of a predetermined delay started at the release of the reset control, and controlling a muting (845, 870) of a speaker (128) in response to the comparison.

Abstract: A system and method for displaying a rich multimedia document in the same window as a desktop window. In one aspect of the invention a client computer connects to a computer network, such as the Internet, and retrieves a channel guide or list of content providers from which a user can select one or more content providers. The client computer retrieves a document associated with a content provider selected from the channel guide. The document is integrated into the desktop window on the client computer. The document received may be an HTML document including hyperlinks for allowing a user to jump to another document (e.g., folder, FTP site, other HTML documents, etc.) associated with the hyperlink.

Abstract: A theme provides a group of multi-media resources for enhancing displays in a graphical user interface to an operating system of a computer according to a topic of the theme. The theme's resources are periodically updated by retrieving updating resources from a remote computer at which the updating resources are stored by a theme provider, so as to provide continually updating enhancements to the graphical user interface display consistent with the theme's topic. The theme's resources can include hypertext templates which define the graphical user interface displays as hypertext pages, allowing the theme to provide a wide variety of enhancements to the displays including text, graphics, hyperlinks, and software components, among others. The theme also enhances a graphical user interface with a view port that plays live or locally cached information from the Internet in each of a plurality of categories, by adding a category for the theme so as to play information from the theme's provider in the view port.
