Abstract: A caulk applicator attachable to a caulk delivery apparatus. The caulk applicator comprises an applicator body having a retainer bracket and a scraper element, wherein the retainer bracket is attachable to the caulk delivery apparatus. An applicator wheel is rotatably mounted to the applicator body and has a fluid application surface, wherein the fluid application surface is engageable with the scraper element.

Abstract: An overvoltage circuit detects differences between the supply voltage from a first circuit and the operating voltage of a second circuit. The circuit may detect when the power supply value of the first circuit is below, above, or equal to the operating voltage of the second circuit. The overvoltage circuit consumes substantially zero static current and may be used in a variety of implementations.

Abstract: A procedure for temporally isolating an environmentally dependent integrated circuit fault includes the steps of determining a marginally failing and a minimally passing environmental condition corresponding to the fault; identifying a clock cycle Tmax at which the fault was first detected; determining a candidate clock cycle at which the fault may have occurred; and iteratively a) applying test pattern subsets from an initial clock cycle through the candidate clock cycle under the marginally failing environmental condition; b) applying remaining test patterns under the minimally passing environmental condition; and c) adjusting the candidate clock cycle based upon whether the fault occurred during test pattern subset application up through the candidate clock cycle under the marginally failing environmental condition. Candidate clock cycle adjustment in accordance with a binary search technique enables determination of an exact clock cycle at which the fault occurred in a maximum of Log2 (Tmax+1) iterations.
