Abstract: An ultrasonic and optical waveguide apparatus includes a face plate and an ultrasonic waveguide extending through a portion of the face plate. The ultrasonic waveguide has a hollow interior with an interior diameter tapered along an elongate axis of the ultrasonic waveguide. The elongate axis of the ultrasonic waveguide is oriented orthogonal to the face plate. An optical shield extends through at least a portion of the hollow interior of the ultrasonic waveguide. The optical shield prevents transmission of a portion of light through the hollow interior.

Abstract: A compact animal waste collector kit includes a hinged lid receptacle which is sized and shaped to be hand-held and support an animal waste bag; and an animal waste bag sized and shaped to fit over an open end of the hinged lid receptacle and in the hinged lid receptacle.

Abstract: A bullet tote includes a hollow structure, closed at one end, and having a removable top at the other end. The interior of the hollow structure contains a separator or dividers for holding and aligning bullets essentially to match a spacing and alignment of a firearms chamber or cylinder so that the bullets may be dumped directly into a firearm chamber or cylinder.

Abstract: A single-path electrical device generates a conductive channel through the air to alternatively convey charge to a target and remove charge from the target. The single-path electrical device uses either a grounding sphere or grounding torroid to store and at least partially dissipate opposite charge. In this way, neither the target nor the single-path electrical device is required to be grounded. The single-path electrical device may operate at a low frequency to help overcome any surface effects of the target.
