Abstract: A hovering remote-control flying craft having a molded frame assembly includes a plurality of arms extending from a center body with an electric motor and corresponding propeller on each arm. In various embodiments, the motor and propeller are mounted downward-facing at a distal portion of each arm with a motor cover over the motor. The center body can be formed of a two-piece molded structure that sandwiches a circuit board to provide structural support for the frame. The circuit board can include a plurality of tabs that facilitate mounting of wire connectors, and can also provide antennas and emitters for both IR and RF communications. In some embodiments, a removable safety ring protects the propellers from lateral contact.

Abstract: A gaming system for enabling three-dimensional game play of remote-control craft controlled by a controller, each craft including a communication system with both radio frequency (RF) and infrared (IR) capabilities. The system can include a plurality of hovering remote-control flying craft each controlled by a handheld controller, and further may include at least one additional game accessory elements, such as a puck, a ground station or a gun. Each pairing of craft and controllers communicate via an RF protocol that transmits at least control communications between the controller and the craft based on pair identification information in an RF communication protocol. The craft and game-accessory elements also communicate via at least an IR protocol that communicates game-play information. Selectable pairs of craft and controllers may be assigned to different teams for playing multiplayer team games based on team identification information in the RF communication protocol.

Abstract: An ultrasonic optical cleaning system is provided for cleaning and deterring the buildup of organic and inorganic particulates from the surface of glassware used in water testing instrumentation. The ultrasonic optical cleaning system includes a transducer that is attached to the surface of the glassware. A connector cap carrying a plurality of spring contacts interconnecting the transducer with an ultrasonic transducer control circuit. The control circuit operates continuously to provide an electrical signal to the transducer that vibrates the transducer and the glassware so that the glassware is cleaned of contaminates.

Abstract: A multi-functional golf club head, designed to be used as a putter and/or chipper, depending on the location of the golf ball. The club head includes golf ball centering indicia on a top face, an angled striking surface, and rails on a flat bottom surface. The ball centering indicia are designed to assist the golfer in aligning the golf ball with the target and the best striking area of the club head. The striking surface of the club head is angled to loft or chip the golf ball from various locations on the golf course, by employing a putting stroke. The rails allow the golfer to chip the golf ball with a smooth putting stroke over fringe grasses. The rails are blunted or curved at the front of the club head so that the head does not catch or snag on a putting surface during a putting stroke.
