Abstract: This Passive Long Range Acoustical Sensor relates to means of sensing acoustical sources and signals, including multi-channel acoustical signals, such as various types of sounds, vibrations, flutter, turbulence, and the like, and at long distances through a natural optical channel, without the use of a laser or other artificial illuminating means. A modified multi-channel embodiment of the Passive Long Range Acoustical Sensor may use a combination of natural optical channels and active illumination means, such as laser or other artificial illuminating means, of producing additional optical channels.
Abstract: This Retractable Stop relates to a new and useful tailgate accessory for trucks and the like. The Retractable Stop may be used to effectively extend the length of a truck bed, and to act as a small auxiliary tailgate or the like, when the truck's primary tailgate is in the horizontal open position.
Abstract: This Retractable Auxiliary Tailgate relates to a new and useful tailgate design for trucks, vans, sport utility vehicles, station wagons, and the like, and may be used to effectively extend the length of a vehicle's payload section.
Abstract: This Auxiliary Tailgate and its related Retractable Stop relate to a new and useful tailgate design for trucks and the like. The Auxiliary Tailgate and Retractable Stop may be used to effectively extend the length of a truck bed, and to act as an auxiliary tailgate or the like, for trucks utilizing this invention. There are several embodiments of the Auxiliary Tailgate and Retractable Stop, including solid frame, open frame, and enclosed clam shell embodiments.
Abstract: This Measuring and Drafting Tool relates to a new and useful type of measuring and drafting tool that may be used to accomplish a plurality of functions using a singular tool. These functions include application as a ruler, straight edge, T-square, square or squaring tool, center gage, an edge transcribing and duplicating tool, and as a tool for striking circles and circle arcs. Some modified embodiments of the Measuring and Drafting Tool are also capable of angle measurement and protractor functions, and may also include one or more bubble levels incorporated into the ruler segments, thereby allowing the user to check if a horizontal surface is level.
Abstract: This Inductive Displacement Transducer relates to a new and useful set of embodiments for a comparator-type relaxation oscillator circuit where the frequency is controlled by variable inductance. Each oscillation of said circuit discharges a fixed amount of charge such that an increase in frequency increases the total current draw of the circuit.
Abstract: This Cleaning Tool for Electronic and Computer Equipment relates to a stick-like device with hook and loop fastener means on one or more of said device's two terminal ends. The Cleaning Tool may be used for removing grease, grime, lint, dust, dirt and the like from electronic and computer equipment. The Cleaning Tool has particular utility as a cleaner of electromechanical mouse devices.

Abstract: This Automatic Safety Flag for Boats and Water Recreational Vehicles relates to a system that automatically raises and lowers a flag mast, which may be telescoping, and with a safety flag located at or near the terminal end of said mast, located on said boat or water vehicle. The flag mast automatically raises the flag when the velocity of the boat or vehicle is traveling below approximately 5 miles per hour or is traveling at a wakeless velocity, and the mast automatically lowers when the boat or water vehicle velocity is above approximately 5 miles per hour. There are two sets of embodiments disclosed. The electromechanical embodiment utilizes an electric motor to automatically raise and to lower the flag mast at said desired water vehicle velocities, and said motor is controlled electrically by a speed transducer, speedometer, or the like.

Abstract: This invention relates to a one-piece and closeable paint roller tray with attached cover, where the paint tray body may securely accommodate a standard sized paint tray liner. The paint tray body is also designed to accommodate paint tools, such as a standard paint brush and a paint roller with handle, within said tray body, when the paint tray invention is in the closed position, with the attached paint tray cover positioned over the paint tray body. Said paint tray is also designed to accommodate said paint tools, on the sloped rollout platform and out of the paint well, with the handle of each tool protruding from two orifices in the front of the paint tray, and when the paint tray is in use. The sloped rollout platform of the paint tray invention has a paint flow channel embedded within said platform, and said channel is designed to also function as stable paint tray legs.
