Abstract: In an information management system, policies are optimized before they are associated to a device in order to increase evaluation speed or reduce space requirements, or both. Optimization techniques may include common subexpression elimination, constant folding, constant propagation, comparison optimization, dead code or subexpression removal, map or lookup table generation, policy rewriting, redundant policy elimination, heuristic-based policy ordering, or policy-format transformation, and combinations of these.

Abstract: A light-emitting display system has an alignment mechanism to align or angle light-emitting tiles of the display. A first tile connects to a second tile by joining a first clamp portion on the first tile with a second clamp portion on the second tile. In an implementation, the alignment mechanism includes a replaceable angle adjustment insert that is inserted into at least one of the clamp portions, such as the first clamp portion. When the first and second clamp portions are joined, a surface of the second clamp portion presses against the insert and a desired angle between the first and second tile is formed. The insert can have any angle so that any desired angle can be formed between the first and second tiles.

Abstract: In an electronic design automation technique for optical proximity correction, an optimized mask function that has values other than those allowed for a particular mask type, such as 0 and 1 for a chrome-on-glass binary mask, evolves it to a solution restricted to these values or narrow intervals near them. The technique “regularizes” the solution by mixing in a new cost functional that encourages the mask to assume the desired values. The mixing in may be done over one or more steps or even “quasistatically,” in which the total cost functional and the mask is brought from pure goodness-of-fit to the printed layout for given conditions to pure manufacturability by keeping the total cost functional minimized step-by-step. A goal of this gradual mixing-in is to do thermodynamically optimal work on the mask function to bring it to manufacturable values.

Abstract: Methods and systems for handling speech recognition processing in effectively real-time, via the Internet, in order that users do not experience noticeable delays from the start until they receive responsive feedback. A user uses a client to access the Internet and a server supporting speech recognition processing. The user inputs speech to the client, which transmits the user speech to the server in approximate real-time. The server evaluates the user speech, and provides responsive feedback to the client, again, in approximate real-time, with minimum latency delays. The client upon receiving responsive feedback from the server, displays, or otherwise provides, the feedback to the user.

Abstract: A circuit is simulated by using system or network tearing to obtain a real solution. The circuit may be an entire integrated circuit, portion of an integrated circuit, or a circuit block. A circuit simulation technique of the invention generates a system graph, finds a tree, and partitions the tree into two or more subtrees. The technique identifies global links and local links in the graph. Each subtree may be solved individually using distributed, parallel computing. Using the results for the subtrees, the technique obtains a real solution, branch voltages and currents, for the circuit.

Abstract: A method and technique of routing interconnects of an integrated circuit providing improved routing quality. In an embodiment of the invention, the technique provides linear spine interconnect routing. In memory array blocks, such as in DRAM and SRAM memory designs, connected pins are generally separated by large distances in a first direction and small distances in a second direction, or a spine or channel region. A route area is defined within the spine region. In one embodiment, obstacles in the route area are identified and corresponding forbidden areas are demarcated. The linear spine interconnect is routed in the first direction within the route area while avoiding the forbidden areas. Pins are connected to the spine interconnect by stitching interconnects. Stitching interconnects are generally routed in the second direction.

Abstract: A technique will automatically route interconnect of an integrated circuit and adjust spacing between tracks or interconnect in order to improve performance or reduce electromigration effects. By increasing spacing between certain tracks or moving tracks, performance can improve because a track will be more noise immunity from nearby tracks on the same layer or on different layers. The automatic router will adjust spacing between tracks depending on one or more factors. These factors may include current associated with a track, width of a track, capacitance, inductance, and electromigration. In a specific implementation, the technique uses a shape-based approach where a grid is not used. The technique may further vary the width of the tracks.

Abstract: A device and method of operation for analyzing signal features over multiple optical wavelengths is presented. A plurality of rotating thin film filters is arranged with respect to a collimated beam of light so that each thin film filter transmits light of a particular wavelength to a detector unit responsive to an angle of incidence of light upon the thin film filter when the thin film filter optically interposes the collimated light beam. Each of the plurality of thin film filters is optically interposed periodically and rotated so that the angle of incidence of light from the first input unit upon the thin film filter varies when the thin film filter is optically interposed to scan the light by wavelength within a selected wavelength band into a detector unit for measurement.

Circuitry connected to the current transformers and line voltage connections meter the energy over the electrical wires.

Abstract: Things are distributed through a personalized network of trusted parties specified by a member. A specific implementation of the invention is for distributing unused tickets, but the principles of the invention are applicable to other things besides tickets. A system of the invention drives or increases attendance by enabling consumers to push their seats (i.e., unused tickets) to members of a trusted network (created by the consumer themselves) rather than making the seats available for sale to the public or manually locating an interested party and transferring them. Additionally, the system performs the time consuming work of contacting members of the trusted network to find out if they are interested in using the tickets for a particular event while receiving and recording their responses.

Abstract: A tunable optical filter is formed by the longitudinal alignment of two opposing end sections of single-mode optical fibers. On at least one of the end sections is a collimator fiber section which is formed from a section of a graded-index, multimode optical fiber which is an odd number of quarter pitches long. The collimator fiber section has an angled end surface which joined to the reciprocally angled end surface of the at least one single-mode optical fiber end section. Piezoelectric material controls the separation between the first and second single-mode optical fiber end sections and sets the wavelengths of optical signals carried through the first and second single-mode optical fiber end sections.

Abstract: A method co-optimizes a design and a library in such a way to choose the best set of cells to implement the design. The method takes into account the idea of limiting the number of new cells while reducing target costs and respecting design constraints. The method chooses a minimum nearly optimum set of cells to optimize a design. This involves the simultaneous optimization of a cell-based design and a cell library used to implement it. The invention can produce only an optimized library for a specific application, when the circuit is disregarded. The method takes into account a set of new cells described as finalized cells or as virtual cells, possibly having different transistor topologies, different sizes, different logic functions, and/or different cell template than the original library.

Abstract: A cell library is automatically designed. An emphasis of a design methodology is on automatic determination of the desired or needed cell sizes and variants. This method exploits different variants on drive strengths, P/N ratios, topology variants, internal buffering, and so forth. The method allows generating libraries that are more suitable for efficient timing closure.

Abstract: A method of extending promotional discounts and special prices on items for sale to identified consumers. After the identification of a consumer by a unique identifier; a selected item is promoted with a discount or special price to the identified consumer. The discount or special price is granted upon a purchase of the item by the identified consumer prior to the withdrawal or termination of the promotion to the identified consumer. The withdrawal or termination of the promotion is held in abeyance upon an acknowledgment of the promotion by the identified consumer. In other words, the identified consumer must take specific action to prevent a promotional discount from being withdrawn. This inverted promotion provides for greater incentives for the consumer to provide information about his or her purchasing habits.
