Abstract: A solar powered air drying system which maintains a dry atmosphere inside a sealed volume. The system uses electricity produced by a solar panel to regenerate daily a desiccant. The desiccant drys the air in a sealed volume which includes the waveguide run and antenna for a Radio Frequency target. The system comprises a solar powered air dryer which operates in conjunction with the natural diurnal temperature cycle. During morning hours, the air volume in the sealed volume is heated by naturally increasing daytime temperatures and the sun and expands, forcing air out of the sealed volume into the solar powered air dryer. The forced air then travels through a desiccant column which includes the desiccant prior to being vented into the environment. Simultaneously, the solar panel provides electrical current to an electric heater which heats the desiccant driving off its stored water. The forced air from the sealed volume then carries the desiccant's moisture with it into the environment.

Abstract: The invention, known as the "Ben Spin," is a novel design for a spinnerbait used in fishing. The new spinnerbait combines a visual and vibratory action that is attractive to many varieties of fresh and salt water fish. This invention provides dual line tie eyes, realistic baitfish fin features, dual barbed hooks with trailer hook mounts, snap back clips and arced blade modifications. The invention's unique features imitate a baitfish as it is pulled through the water. The flash of the novel blade's resulting air bubbles visually stimulates the attacking fish. The unique spinner blades produce an alluring and attractive sound to most predatory fish. Other fish attack the instant invention lure in response to perceived antagonistic vibration. The novel spinnerbait, known as a "Ben Spin," appeals to a fish's instincts and normal reactions to sight and sound stimuli and provides an increased advantage to the fisherman.
