  • Patent number: 7520098
    Abstract: A shingle includes a body having an upper end, a lower end, a top surface, a bottom surface, a first side and a second side. The body has a width defined as the distance between the two opposing sides, a length defined by the distance between the upper end and the lower end. In a preferred embodiment, the shingle also includes a side wall that extends downward from the body adjacent one of the sides and extends the length of the shingle. The side wall preferably includes an angular projection disposed toward the upper end.

  • Patent number: 7340695
    Abstract: A hardware-based acceleration platform for computational electromagnetic algorithms, specifically the finite-difference time-domain (“FDTD”) method, comprises reformulating the FDTD algorithm in order to make it more hardware friendly. This reformulation makes use of split fields at every node in the mesh, and combines total- and scattered-field formulations into a single, hybrid formulation. By precomputing coefficients for the nodes in the mesh, it is possible for a single set of equations to support plane waves, point sources, PML ABCs, and PEC walls. In the method sources are determined by means of a lookup table, rather than through direct hardware computations. All of these modifications enable the hardware designer to much more easily develop an FDTD accelerator.

  • Patent number: 7134092
    Abstract: The present invention comprises a graphical user interface tool particularly adapted for use with a program that shows multiple files simultaneously, each in a different panel of the display. The tool presents the user with a series of optional actions that can be taken in connection with the file that is displayed within one panel of the display. In accordance with the invention, a user manipulates a cursor to a position in one of the multiple panels on a display screen and issues an instruction to invoke the tool, such as by clicking on the right mouse button. The tool is then made to appear and displays a series of optional operations from which the user may select. The operations are specific to the file in the panel within which the tool was invoked.

  • Publication number: 20060169831
    Abstract: A method for ballistic target defense including identifying a launched ballistic target having a target launch point, a target launch direction, a target speed, and a target trajectory; launching a target interceptor in a launch direction that is generally the same as the target launch direction and with a speed that is less than the target speed; providing the interceptor with an approximate target intercept trajectory, and accelerating the interceptor at an approximate point of intercept to substantially match the target trajectory. During a relatively long target engagement time, the interceptor has approximately a zero net relative velocity with respect to the target.

  • Publication number: 20050154546
    Abstract: A computer hardware configuration for performing the pseudo-spectral time-domain (PSTD) method on data. The hardware configuration includes a forward fast Fourier transform (FFT) unit that calculates a forward fast Fourier transform (FFT) from the data, and a complex multiplication unit that receives the FFT-processed data and calculates a spatial derivative in the frequency domain from the FFT-processed data. The hardware configuration further includes an inverse fast Fourier transform (IFFT) unit that converts the spatial derivative in the frequency domain from the complex multiplication unit into the time domain, and a computation engine that solves a PSTD equation based upon the spatial derivative in the time domain received from the IFFT unit.

  • Publication number: 20050120178
    Abstract: Disclosed herein is an organization of cache memory for hardware acceleration of the FDTD method. The organization of cache memory for hardware acceleration of the FDTD method provides a substantial speedup to the finite-difference time-domain (FDTD) algorithm when implemented in a piece of digital hardware. The organization of cache memory for hardware acceleration of the FDTD method utilizes a very high bandwidth dual-port on-chip memory in a particular way. By creating many small banks of internal memory and arranging them carefully, all data dependencies can be statically wired. This allows for a many-fold speedup over SRAM-based solutions and removes the burden of data dependence calculation that streaming SDRAM-based solutions must perform.

  • Patent number: 6854945
    Abstract: In combination, an elongated tool having a striking end and a tapered insertion end and a drift pin cap. The drift pin cap includes a cap body having an upper end, a lower end and at least one side wall extending between and connecting the upper end and the lower end. A drift pin receiving cavity is formed in the lower end of the cap body which extends upwards towards the upper end within the cap body, the pin receiving cavity having a diameter smaller than a diameter of the cap body. The pin receiving cavity is operative to fit over and be retained on the striking end of the tool such that when the tool is impacted by a driving device, the drift pin cap is interposed between the tool and the driving device to prevent damage to the tool yet still permit driving of the tool.
