摘要： A load securement device may comprise an extendable pole and a plurality of attachments. The device may be operable to manipulate a tie down of a cargo trailer. As non-limiting examples, the tie down may be a cargo strap, a cargo chain, or an elastic cord used to secure a cargo or to secure a tarp over the cargo. The extendable pole may be lengthened to reach the top of the cargo. The extendable pole may be shortened to take up less space for storage. The plurality of attachments may alter a distal end of the extendable pole to enable the extendable pole to perform multiple tasks necessary for securing the cargo. As non-limiting examples, the plurality of attachments may enable the extendable pole to toss the cargo strap, to pull the cargo strap, or lift a hard corner.

摘要： A novel mismatched-shaping DAC architecture is described. The inventive DAC partially spectrally shapes data conversion errors. In accordance with the present invention, the DAC mismatch-shaping function is fully effective for input signal amplitude levels that are relatively low (i.e., close to mid-scale), however, the mismatch-shaping function is not fully effective for input signal amplitude levels that are relatively high. This results in the simplification in complexity, reduced power dissipation, and shortened propagation delays associated with the mismatch-shaping DAC digital logic circuitry. Exemplary delta-sigma ADC and DAC architectures adapted for use with the present inventive partial mismatch-shaping DAC are also described.
