Abstract: The invention relates to an HVAC apparatus, method, and system. Aspects of the invention include a supplemental heat source with an air handler unit for a conventional forced air heating and cooling system. The supplemental heat source in one example is a hydronic subsystem. It can be used alone or to supplement the forced air subsystem. Another aspect of the invention includes an air handling subsystem that has a housing that can be highly flexible in configuration and installation. The housing can support internal components, including a hydronic or other supplemental heat source with the forced air components. At least two sides of the housing can be configured for access for maintenance and repair. A control system can be designed to eliminate need for defrost cycle for forced air refrigeration-type subsystem and/or for better maintenance for comfort in the air conditioned space.

Abstract: A manual universal punching and welding apparatus includes a body frame having at least a vertical wall; a pair of supporting arms that are attached to the body frame and clamp a portion of the work object; a punching head that rotates clockwise and counterclockwise in a plane defined by the vertical wall of the body frame; and a welding part for welding the work object loaded on the work object loading part of the punching head. As for an efficiency of the present invention, a single manual punching/welding apparatus may produce all types of parts that require punching and welding. In addition, compared to the maintenance of a large number of designated machines, only one universal machine would desire maintenance, which greatly reduces the burden of overall maintenance.

Abstract: A thin-film transistor comprises an annealed layer comprising crystalline zinc oxide. A passivation layer is adjacent to the thin-film transistor. The passivation layer has a thickness and material composition such that when a dose of radiation from a radiation source irradiates the thin-film transistor, a portion of the dose that includes an approximate maximum concentration of the dose is located within the annealed layer. The annealed layer has a thickness and threshold displacement energies after it has been annealed such that: a) a difference between a transfer characteristic value of the thin-film transistor before and after the dose is less than a first threshold; and b) a difference between a transistor output characteristic value of the thin-film before and after the dose is less than a second threshold. The thresholds are based on a desired performance of the thin-film transistor.
