Abstract: A low-power, automated weight logger may include a weighing scale having an electronic load cell and a data logger having a memory and a battery power supply. An adapter circuit may be connected to the electronic load cell and the data logger. The adapter circuit may include a battery power supply, a switchable voltage regulator, and an amplifier. The data logger may switch the voltage regulator in the adapter circuit on and off. The amplifier may amplify a signal from the load cell and send the amplified signal to the data logger. The voltage regulator may regulate power from the power supply to the load cell.

Abstract: An air deflector for a power boat has an airfoil mounted along the top frame of the windshield with brackets so as to form a gap between the airfoil and the windshield. Forward motion of the boat produces a downward flow of air into the cockpit area. A clamp bar is mounted on the top surface of the airfoil and includes snap fasteners for attaching the forward edge of a canvas top.
