  • Publication number: 20120138559
    Abstract: A modular structural load bearing device including light-weight composite structural members each including an elongated body having at least one internal recess for a cable in the recess or series of recesses. Preassembled and presized composite support members and connectors can form a modular structure, such as a crane. When used, end pieces or other components on an end of the elongated body can secure a cable. For assembly of the structural load bearing apparatus, connectors can be used with composite structural members that are light-weight with relatively thin walls while providing enhanced benefits for resisting the combination of tension, compression and buckling forces.

  • Publication number: 20100137249
    Abstract: The present disclosure encompasses compounds and compositions that are useful as specific AI-2 antagonists for the control of bacterial quorum sensing. Although the AI-2 antagonists according to the present disclosure may not have bactericidal effect, their ability to attenuate virulence, drug resistance, and/or biofilm formation have therapeutic benefits. In addition, the AI-2 antagonists of the present disclosure can also be used as tools to probe bacterial AI-2 functions. The present disclosure also encompasses methods for inhibiting or attenuating microbial virulence, biofilm formation, and drug resistance. The methods are suitable for preventing bacteria from accruing and forming extensive biofilms that may be a health or hygiene hazard or a physical issue, such as in the blockage of water or fuel lines.

  • Publication number: 20090172062
    Abstract: A fast Fourier transform (FFT) is performed on first-fourth input data points. Real and imaginary portions of the first input data point are stored in first and second registers. Real and imaginary portions of the second input data point are stored in third and fourth registers. Real and imaginary portions of the third input data point are stored in fifth and sixth registers. Real and imaginary portions of the fourth input data point are stored in seventh and eighth registers. Operations are performed in place in the first-eight registers and in a ninth register to generate a first-fourth output data points stored in the registers that represent an FFT of the first-fourth input data points. The radix-4 FFT may be cascaded to perform higher bit-level FFTs on sets of data points. Furthermore, the data points may be reordered between cascaded radix-4 FFTs to enable efficient use of memory.

  • Publication number: 20090113175
    Abstract: In one embodiment, a processor architecture for concurrently fetching data and patched instructions includes a microprocessor, an instruction patch, a dedicated instruction memory, a patch memory, and a dedicated data memory. The instruction patch is coupled to the microprocessor by an instruction bus, and is also coupled to the dedicated instruction memory and the patch memory. The patch memory and the dedicated data memory are coupled to the microprocessor by a data bus separate from the instruction bus. In one embodiment, the instruction patch has a number of comparators that can be individually enabled by respective enable signals. Each comparator that is enabled compares every bit on an instruction address with a corresponding bit of a patched instruction address to detect a patch condition. When a patch condition is detected, patched instructions are fetched from the patch memory, while the microprocessor can concurrently fetch data from the dedicated data memory.
