A work platform includes a plank which telescopes to a desired width. The work platform includes a first leg assembly rotatably attached adjacent to a first end of the plank. The work platform includes a second leg assembly rotatably attached adjacent to a second end of the plank. The plank is in an open position when the plank is supported by the first leg assembly and second leg assembly and the first leg assembly and second leg assembly form an angle greater than 25 degrees with the plank. The plank is in a closed position when the first leg assembly and second leg assembly are adjacent to and in parallel with the plank. A method for using a work platform.

摘要:
A target interface system for interfacing selected components of a communication system and methods for manufacturing and using same. The target interface system includes target interface logic that is distributed among a plurality of reconfigurable logic devices. Being coupled via a serial link, the reconfigurable logic devices each have an input connection for receiving incoming data packets and an output connection for providing outgoing data packets. The serial link couples the input and output connections of successive reconfigurable logic devices to form a dataring structure for distributing the data packets among the reconfigurable logic devices. Thereby, the dataring structure maintains data synchronization among the reconfigurable logic devices such that the distribution of the target interface logic among the reconfigurable logic devices is transparent to software.
摘要:
A target interface system for interfacing selected components of a communication system and methods for manufacturing and using same. Being reconfigurable to support an extensive range of conventional input/output technologies, the target interface system downloads a selected image associated with a desired input/output technology prior to runtime. The selected image identifies an appropriate output driver supply voltage, and any auxiliary voltages are controlled as functions of the output driver supply voltage to limit voltage inconsistencies. Defaulting each voltage to its least dangerous state when unprogrammed, the target interface system subsequently monitors the voltages, disabling the input/output connections if a problem is detected. The target interface system likewise detects when a selected system component is absent, unpowered, and/or wrongly powered and provides contention detection. Thereby, the target interface system can facilitate communication among the system components while inhibiting damage to the target interface system and/or the system components.

Chimeric T cell receptors (TCR) are provided that combine, in a single chimeric species, the intracellular domain of CD3 ζ-chain, a signaling region from a costimulatory protein such as CD28, and a binding element that specifically interacts with a selected target. When expressed, for example in T-lymphocytes from the individual to be treated for a condition associated with the selected target, a T cell immune response is stimulated in the individual to the target cells. The chimeric TCR's are able to provide both the activation and the co-stimulation signals from a single molecule to more effectively direct T-lymphocyte cytotoxicity against the selected target and T-lymphocyte proliferation.
摘要:
A signal conversion system for interfacing selected components of a communication system and methods for manufacturing and using same. The signal conversion system converts selected logic signals from one system component into a pair of differential logic signals and provides the pair of differential logic signals to a second system component, resolving any logical and/or temporal artifacts. While one or more of the selected logic signals change signal state, the signal conversion system maintains the pair of differential logic signals in a first valid combined signal state until the signal state of the selected logic signals corresponds to a second valid combined signal state for the pair of differential logic signals. The signal verification system then updates the pair of differential logic signals to have the second valid combined signal state. The system components thereby can communicate, exchanging differential communication signals while maintaining duty cycle and avoiding signaling glitches.

Integrated processes of preparing industrial chemicals starting from seed oil feedstock compositions containing one or more unsaturated fatty acids or unsaturated fatty acid esters, which are essentially free of metathesis catalyst poisons, particularly hydroperoxides; metathesis of the feedstock composition with a lower olefin, such as ethylene, to form a reduced chain olefin, preferably, a reduced chain α-olefin, and a reduced chain unsaturated acid or ester, preferably, a reduced chain α,Ω-unsaturated acid or ester. The reduced chain unsaturated acid or ester may be (trans)esterified to form a polyester polyolefin, which may be epoxidized to form a polyester polyepoxide. The reduced chain unsaturated acid or ester may be hydroformylated with reduction to produce an α,Ω-hydroxy acid or α,Ω-hydroxy ester, which may be (trans)esterified with a polyol to form an α,Ωpolyester polyol. Alternatively, the reduced chain unsaturated acid or ester may be hydroformylated with reductive amination to produce an α,Ω-amino acid or α,Ω-amino ester, which may be (trans)esterified to form an α,Ωpolyester polyamine.

The present invention discloses a communication system network that comprises a plurality of communication systems and a processing multiplexer. The communication systems, which may be either conventional communication systems and/or trunked communication systems, transmit digitized audio signals and communication system data to the processing multiplexer. Based on signal destination data, which is part of the communication system data, the processing multiplexer processes the digitized signals and routes the resultant signals to the appropriate signal destinations.
