Abstract: An autonomous decoy device is disclosed. The autonomous decoy comprises a decoy shell, a propulsion system, the propulsion system, a steering apparatus, a receiver, a memory, and a microcontroller. The decoy shell has a form resembling an animal in life size or near life size proportions. The propulsion system is adapted to move the decoy device in or on a desired medium and the steering apparatus is adapted to control the direction of movement of the decoy device. The receiver is adapted to receive an electromagnetic signal and determine a relative strength of the signal. The memory is adapted to store at least one instruction set. The microcontroller is adapted to control the propulsion system and the steering apparatus based on the at least one instruction set and the relative strength of the signal. Various autonomous routines and methods of use are further described herein.

Abstract: Disclosed is a portable air filtration system for removing contaminants from room air. In one embodiment, the air filtration system includes a power supply and an air blower module electrically connected to the power supply. The air filtration system further includes an ionization module engaged with the air blower module and including a first control grid and a high voltage grid electrically connected to the power supply. The air filtration system further includes a filter module removably engaged with the ionization module. The filter module includes a filter and a second control grid. Engagement of the filter module and the ionization module creates an electrical connection between the second control grid and the power supply. Activation of the air filtration system creates a first ionization field between the high voltage grid and the first control grid and a second ionization field between the high voltage grid and the second control grid.

Abstract: Multi-port valve assemblies with, typically, two-piece housings are disclosed. Particularly useful in connection with swimming pools and associated water pumps, the assemblies avoid reliance on an elongated handle to effect rotation of the internal structure of the valve. Instead, the assemblies utilize a knob—which users need not lift—coupled to a post in which an elongated slot is formed. Doing so avoids breakage problems associated with use of elongated handles while reducing wear of internal seals. Each valve assembly additionally may include a cam having non-semicircular, asymmetrically-shaped recesses into which followers attached to a shaft passing through the elongated slot are received.
