    摘要： A programmable data path device capable of operating as a general purpose hardware accelerator. The device includes a plurality of processing cells, memory such as RAM or EPROM for storing data path control words, and an address module for sequentially providing data path control words to the processing cells. Each cell includes an ALU, a multiplexer and a register. For each cell, in response to the data path control word, the multiplexer selectively couples the contents of one register to one of the ALU input ports, and the ALU performs a selected operation and places its output into the register of that cell. Thus, through the data path control words, a device can be configured to operate in a sequential, pipeline, or parallel mode, permitting a wide variety of digital signal processing functions to be performed with a single system.

    摘要： A solar heat collector built about a new collector matrix formed from flexible sheet material, such as metallic foil. The matrix presented by the foil is folded into an accordion shape to form a series of linear channels to trap solar energy. The absorbed energy is transferred to air flowing through the channels. Proper support for the expended collector matrix is provided by taut lines stretched across a supporting frame and engaged with the folded flexible sheet. Inner and outer circulation channels are provided to permit air circulation by natural heating currents. The folded sheet and lines are constructed in kit form for expansion and support at the location of use. Transverse spacers might be included between pleats.

    摘要： Pyrogenic toxins, such as staphylococcal enterotoxins, modified in the disulfide loop region are provided. The modified toxins retain useful biological properties but have substantially reduced toxicity compared to the corresponding unmodified native toxin. The native pyrogenic toxins are typically modified by deletions within the disulfide loop region to produce modified enterotoxins having 100-fold or greater decrease in toxicity.

    摘要： The present invention provides methods and compositions for eliminating virally-infected cells by administering a Shiga-toxin composition, and the present invention provides methods and compositions for suppressing bovine leukemia-related cell proliferation. In the methods, a Shiga-toxin composition is administered in an amount effective to suppress bovine leukemia-related cell proliferation. The Shiga-toxin composition can include a Shiga-toxin polypeptide; a probiotic microorganism expressing a Shiga-toxin polypeptide; or a transgenic plant expressing a Shiga-toxin polypeptide. In one embodiment, the Shiga-toxin polypeptide is Stx1A and, in another embodiment, the Shiga-toxin polypeptide is Stx1 holotoxin. In yet a further embodiment, the Shiga-toxin polypeptide comprises Stx2.

    摘要： A shifter circuit comprises a high and low voltage buffer stages and an output buffer stage. The high voltage buffer stage comprises multiple transistors arranged in a transistor stack having a plurality of intermediate nodes connecting individual transistors along the stack. The transistor stack is connected between a voltage level being shifted to and an input voltage. An inverter of this stage comprises multiple inputs and an output. Inverter inputs are connected to a respective intermediate node of the transistor stack. The low voltage buffer stage has an input connected to the input voltage and an output, and is operably connected to the high voltage buffer stage. The low voltage buffer stage is connected between a voltage level being shifted away from and a lower voltage. The output buffer stage is driven by the outputs of the high voltage buffer stage inverter and the low voltage buffer stage.
