  • Computer combinatorial multipliers in programmable logic devices
    Patent number: 7176715
    Abstract: Disclosed is a device and method for configuring a register in a PLD to operate as a logical AND gate. So configuring a register allows it to be used in a multiplication carried out by the PLD. A logic element includes a combinatorial logic section and at least one register interconnected with the combinatorial logic section. The register is configured to operate as a logical AND gate. The logic element can include a data input, a clear input, and a load input wherein the load input can be held high, a first bit to be ANDed can be input on the data input and a second bit to be ANDed can be input on the clear input. The logic element can, for example be configured to carry out at least a portion of a multiplication of a multiplicand and a multiplier.

  • Steel-wood system
    Patent number: 6167675
    Abstract: A web-reinforced wood joist defines a top edge surface, a bottom edge surface opposite to the top edge surface, a first lateral web surface, and a second lateral web surface opposite to the first lateral web surface. A longitudinal metal reinforcement is applied to at least one of the first and second lateral web surfaces. This metal reinforcement includes at least one sheet metal strip formed with integral teeth distributed at predetermined intervals along the entire length thereof and driven into the wood to fixedly secure the metal reinforcement to the joist's wood. This web-reinforcing method is suitable to reinforce any type of elongated structural wood members to improve their strength in bending, direct tension, direct compression, direct shearing and any combination thereof.
