摘要： An apparatus and method for creating expanded and non-expanded regions on a sheet of sheet metal. The apparatus includes a programmable controller, a sheet metal feeder for incrementally advancing the sheet metal, and a cutter/expander for generating rows of expanded metal apertures. The controller selectively controls both the amount of incremental advance provided to the sheet metal by the feeder and the timing and location of the cutting and expanding provided by the cutter/expander; the combination of which creates such regions.

摘要： An analog process/voltage/temperature (PVT) compensated buffer includes a differential amplifier providing a first output signal indicative of a difference between an input signal and a reference signal. The input signal is compatible with a first type of logic. An active gain stage is coupled to translate the first output signal to a second output signal. The second output signal is compatible with a second type of logic. The differential amplifier and the active gain stage are coupled to receive a process/voltage/temperature (PVT) compensation signal. In one embodiment, the first type of logic is Gunning Transceiver Logic (GTL) and the second type of logic is complementary metal oxide semiconductor (CMOS) logic.

摘要： A repositionable downspout extension that is attached to a downspout to direct rainwater away from a building. The extension is a generally tubular body with first and second ends. The extension comprises a pair of selectively removable adapter portions at each end that allow the extension to be connected to a downspout. An interlockable collar portion is at each end of the extension and interior to the adapter portions. The interlockable collar portions allow a number of the extensions to be connected together to form a downspout extension assembly after the adapter portions are removed. The extension further comprises an adjustable portion between the two collar portions. The adjustable portion comprises collapsible corrugations so that the extension can be bent into a number of positions and hold its position.
