Abstract: A hearing aid circuit includes a plurality of sub-circuits implemented as a plurality of flexible circuit boards. In various embodiments, the plurality of flexible circuit boards includes a motherboard that can be used with multiple hearing aid models and different peripheral boards that can provide different hearing aid models with their unique styles and/or functional features. In various embodiments, the hearing aid circuit is assembled in an automated process that connects the motherboard to one or more peripheral circuit boards using surface mount technology (SMT).

Abstract: A single-axle tractor for moving trailers and wheeled cargo. The single-axle tractor of the present disclosure provides a compact, efficient, reliable, cost-effective means of moving cargo from one place to another using torque generated by an on-board motor. The tractor includes a structure to provide rigidity to a tractor-trailer combination while providing reasonable roll compliance.

Abstract: A method, computer program, or apparatus for determining with various degrees of precision the power delivered by an engine and also the best possible power of the engine for the given operating conditions. Typically, this invention is for an aircraft engine. The disclosed invention uses a variety of parameters, such as the rotation rate, manifold pressure, outside air temperature, and fuel flow to calculate or approximate the power delivered by the engine and the best power available from the engine. The engine's altitude does not have to be involved in the calculations. Display of the calculated engine power is provided relative to best power and/or maximum engine power.

Abstract: A container or receptacle capable of measuring a small, “micro” amount, for example, 2 ounces of fertilizer, and then also capable of measuring a larger, “macro” amount, for example, 1 gallon of water, without the need for a secondary measuring device such as a measuring cup. This is accomplished through the use of a supplemental measurement depression formed in the bottom of the receptacle. The supplemental measurement depression is used for measuring the micro amount and the more familiar measurement graduations on the sidewall of the container are used for measuring the macro amount. Four embodiments are presented detailing various configurations of the invention.
