  • Publication number: 20200164240
    Abstract: A transportable fire training apparatus includes a trailer frame having a rear raised section at a rear end of the trailer frame and an unraised section at a middle portion of the trailer frame, a shell attached to the trailer frame and partitioned into a plurality of training rooms, a rear multi-axle wheel set disposed below, and attached to, the rear raised section of the trailer frame via an air ride suspension system that raises the trailer frame relative to the a rear multi-axle wheel set in response to pressurization of the air ride suspension system. The unraised section of the trailer frame rides substantially above the ground when the air ride suspension system is in a pressurized state and rests on the ground when the air ride suspension system is in an unpressurized state. A method for deploying and using the transportable fire training apparatus is also disclosed herein.

  • Publication number: 20110138305
    Abstract: A method and system for random matching of two individuals from within computer generated virtual pools of individuals with means for rapid, real-time, interactive assessment of their mutual compatibility on mobile and computer devices. Participating individuals indicate via device interfaces their availability for matching and the system determines and registers their locations. Participating individuals place requests for matching and the system algorithmically constructs proximity based virtual matching pools. For each matching request, an individual is selected randomly from the virtual matching pool and the two matched individuals are placed in a real-time, synchronous, compatibility assessment session. The system presents the matched individuals with a sequence of questions, tabulates the individual responses, calculates a matching score, and displays the matching score simultaneously to both participants in the compatibility assessment session.

  • Publication number: 20080112441
    Abstract: A method of performing node-based static timing analysis on a digital network and a program storage device for implementing the method, wherein the method comprises partitioning timing delays in the digital network into portions attributable to a factor of interest and portions attributable to other factors; multiplying the timing delays by different weights based on the factor of interest to produce weighted timing delays; and using the multiplied timing delays to determine a relative impact of the factor of interest on the various paths in the digital network. The method further comprises setting arrival times of timing signals at digital network path start points to zero and identifying digital network paths whose timing delays are dominated by a particular factor of interest. The different weights comprise any of a positive weight, a negative weight, and a zero weight.

  • Publication number: 20080074147
    Abstract: An electrical wiring structure and a computer system for designing the electrical wiring structure. The electrical wiring structure includes a wire pair. The wire pair includes a first wire and a second wire. The second wire is slated for being tri-stated. The wire pair has a same-direction switching probability ?SD per clock cycle that is no less than a pre-selected minimum same-direction switching probability ?SD,MIN or has an opposite-direction switching probability ?OD per clock cycle that is no less than a pre-selected minimum opposite-direction switching probability ?OD,MIN. The first wire and the second wire satisfies at least one mathematical relationship involving LCOMMON and WSPACING, where WSPACING is defined as a spacing between the first wire and the second wire, and LCOMMON is defined as a common run length of the first wire and the second wire.

  • Publication number: 20080072184
    Abstract: Disclosed is a method for enhanced efficiency and effectiveness in achieving closure of large, complex, high-performance digital integrated circuits. Circuit macros are re-optimized and re-tuned in the timing closure loop by means of a reformulated objective function that allows the optimizer to improve the slack of all signals rather than just the most critical one(s). The incentive to improve the timing of a sub-critical signal is a diminishing function of the criticality of the signal. Thus all signals are improved during the optimization, with the highest incentive to improve on the most critical signals, leading to faster and more effective overall timing closure.

  • Publication number: 20080052656
    Abstract: A method, system and program product are disclosed for improving an IC design that prioritize failure coefficients of slacks that lead to correction according to their probability of failure. With an identified set of independent parameters, a sensitivity analysis is performed on each parameter by noting the difference in timing, typically on endpoint slacks, when the parameter is varied. This step is repeated for every independent parameter. A failure coefficient is then calculated from the reference slack and the sensitivity of slack for each of the timing endpoints and a determination is made as to whether at least one timing endpoint fails a threshold test. Failing timing endpoints are then prioritized for modification according to their failure coefficients. The total number of runs required is one run that is used as a reference run, plus one additional run for each parameter.

  • Publication number: 20070226667
    Abstract: A method, system and computer program product for analyzing and modifying a static timing slack of a timing path in a static timing analysis of a design of an integrated circuit (IC) with a transient power supply are disclosed. A static timing slack analysis is performed at a selected endpoint in an IC to obtain a candidate timing path leading to the endpoint with a worst static timing slack. A transient static timing slack is determined for the candidate timing path for each clock cycle of a clock signal under the transient power supply. The determined transient static timing slack is used to adjust the timing of the IC and to modify the static timing slack of the candidate timing path.

  • Publication number: 20070220345
    Abstract: Systems and methods are provided for analyzing the timing of circuits, including integrated circuits, by taking into account the location of cells or elements in the paths or logic cones of the circuit. In one embodiment, a bounding region may be defined around cells or elements of interest, and the size of the bounding region may be used to calculate a timing slack variation factor. The size of the bounding region may be adjusted to account for variability in timing delays. In other embodiments, centroids may be calculated using either the location or the delay-weighted location of elements or cells within the path or cone and the centroids used to calculate timing slack variation factor. The timing slack variation factors are used to calculate a new timing slack for the path or logic cone of the circuit.
