Abstract: A portable engraving system comprises an enclosure adapted to operably accommodate an engraving device, wherein the enclosure comprises an adjustment system. The adjustment system comprises one or more adjustable devices, and the adjustable devices are adapted to adjust a distance between the enclosure and a work surface thereby allowing adjustment of the distance between the enclosure and the work surface, whereby the enclosure is adjustable with respect to the work surface. The enclosure further comprises an opening wherein the engraving device is operably positioned thereto, whereby the work surface is accessible to the engraving device therethrough. The enclosure is positionable adjacent the work surface and operably disposed thereto.

Abstract: An automatic depth controlled cutting assembly for a stump grinder includes a cutting assembly operatively attached to a stump grinder for engaging and grinding a stump, an actuating assembly to actuate movement of the cutting assembly relative to the stump, and an automatic depth control system cooperating with the actuating assembly to automatically control a depth of the cutting assembly relative to the stump.

Abstract: A weapon sight to facilitate alignment a weapon with a target comprises a housing further comprising a video camera for generating a first video signal corresponding to a first field of view, a processor for processing the first video signal into a second video signal corresponding to a second field of view and outputting the second video signal to a video display, and a reticle disposed on the video display, wherein one of the first or the second video signals is electronically positionable with respect to other of the second or first video signal.

Abstract: A multi-functional tool assembly for a material processing machine includes a single tool including a head and a shaft integrally formed therein. The head has a cavity with an arcuate surface. The multi-functional tool assembly also includes a material reducer adapted to reduce material within the waste processing machine. The material reducer is disposed in the cavity and has an arcuate surface complementary to the arcuate surface of the cavity.

Abstract: A cylinder tote for carrying a compressed gas cylinder of the type having a flangeless neck and a valve assembly mounted atop thereof includes a handle member having a first end and an open-ended opposite end, a yoke member having a second end and an open-ended third end, the third end including a pair of legs adapted to support the valve assembly, and an intermediate member disposed between and connecting the first end of the handle member and the second end of the yoke member wherein, when the yoke member is disposed on and engages the valve assembly disposed atop the compressed gas cylinder, the cylinder tote may be used to transport the compressed gas cylinder.

Abstract: An embodiment of a method for measuring an RMS voltage of an arbitrary time-varying waveform includes: a) coupling said arbitrary time-varying waveform to said thermally sensitive device; b) decoupling said arbitrary time-varying waveform from said thermally sensitive device; c) coupling said thermally sensitive device to said controlled DC voltage source; d) measuring a current through said thermally sensitive device at least two points in time; e) determining a change in said current over said at least two points in time; f) if said current is increasing between said at least two points in time, then decrease said controlled DC voltage source responsive to determining that said current is increasing; g) if said current is decreasing between said at least two points in time, then increase said controlled DC voltage source responsive to determining that said current is decreasing; and h) repeating steps a)–g).
