Abstract: There is presented a method for driving a piezoelectric device and an atomizer for atomizing a fluid, and an atomization method for a fluid using a piezoelectric device; the atomizer employs a piezoelectric device and circuitry that uses a switching voltage across the piezoelectric device at an operating frequency; sensing a sensed voltage corresponding to a phase of the piezoelectric device; and responsive to whether the sensed voltage is in phase or out of phase relative to the switching voltage, changing the operating frequency provided to the piezoelectric device, and the changing is one of: increasing the operating frequency by a first value, or decreasing the operating frequency by a second value.

Abstract: A vibrating piezoelectric atomizer comprising: a piezoelectric tube having a length, a first end defining an opening and a second end, the second end of the piezoelectric transducer tubular body is connected to a horn; the horn is dimensioned to be half wavelength resonator; the horn is folded and located alongside the piezoelectric tube; a metallic disk is connected to the horn near the first end of the piezoelectric tube, whereby by applying an alternating voltage across electrodes of the piezoelectric tube, the piezoelectric tube is excited into a resonant vibration when frequency of excitation equals to half wavelength resonant frequency of the piezoelectric tube's length and vibrates in synchronism and is communicated to the metallic disk to atomize a liquid.

Abstract: Described herein is a combination pitching aid and batting tee apparatus. The apparatus includes a base having a front and a rear, a stand extending upwardly from the base, a support rod extending upwardly from the stand, and an arm extending outwardly from the support rod. The arm includes a target associated therewith that can be adjusted vertically and horizontally. The apparatus includes a screen having a top end and a bottom end and a support assembly having a top end and a bottom end that extends upwardly from the base. The bottom end of the screen is attached near the front of the base and the top end of the screen is attached to the support assembly. The support rod can be replaced with a batting tee.

Abstract: Embodiments are directed to containers for storage and transportation of items such as produce harvested with its roots intact. The containers include a base and lid hingedly connected together on at least one edge, and may be stacked to maximize density for storage so that a shipping receptacle can hold more produce while taking up the same place, allowing for more efficient transportation saving on transportation costs and storage. In addition to saving costs on transportation and storage, the containers maintain the freshness of the produce harvested with its roots intact by keeping away soil, soil debris and moisture from the remaining portions of the produce. When containers are stacked together, a top surface of the lid of a first container is adapted to receive a plurality of longitudinal concave grooves on the bottom surface of the base of a second container.
