Abstract: Techniques for an analog-to-digital converter (ADC) using pipeline architecture includes a linearization technique for a spurious-free dynamic range (SFDR) over 80 deciBels. In some embodiments, sampling rates exceed a megahertz. According to a second approach, a switched-capacitor circuit is configured for correct operation in a high radiation environment.

Furthermore, even though it is manufactured in a commercial 0.25-?m CMOS technology (1 ?m=12?6 meters), it maintains this performance in harsh radiation environments. Specifically, the stated performance is sustained through a highest tested 2 megarad(Si) total dose, and the ADC displays no latchup up to a highest tested linear energy transfer of 63 million electron Volts square centimeters per milligram at elevated temperature (131 degrees C.) and supply (2.7 Volts, versus 2.5 Volts nominal).

The closure cap carries an applicator brush that is manually advanceable or retractable with respect to the closure cap. The mouth of the container is covered by an apertured transverse wall and a lid thereon, the lid normally blocking communication between the powder in the container and the brush. When the closure cap is removed, the lid can be manually lifted by means of a hinged connection, to as to expose a small accumulation of powder that has adhered to the transverse wall. The applicator brush is then advanced, and used in the manner of a dabber to pick up particles of the powder and apply them to the user. Simplified components and assembly characterize the completed unit.

Abstract: A beverage container includes a can body having a side wall, a neck portion of reduced diameter, a closure lid and an anchor structure on the closure lid. The anchor structure is offset with respect to the center of the lid. A pull tab has a mounting hole which fits onto the anchor structure. One end of the pull tab has a grip handle, and the other end has a puncturing nose. The pull tab is turnable on the anchor structure, and thus also turnable with respect to the closure lid. The pull tab is of a length whereby it normally just fits between the opposite locations of a peripheral groove on the closure lid. The pull tab can be manually turned from a first position overlying the closure lid, to a second position wherein it overhangs one part of the peripheral groove. The construction thus provides an extended handle length to permit the user to more easily grasp and raise the pull tab, and open the container, for use.
