Abstract: A bottle puzzle used as a training or learning tool for children and adults with cognitive disabilities has puzzle pieces with uniquely shaped concave and convex walls, with only one wall in one puzzle piece matching another wall in a different puzzle piece. Each puzzle piece is a fully contained compartment capable of holding and dispensing beverages. When puzzles are put together, they form a normal bottle that can be filled with beverages contained in the puzzle pieces. A mixing chamber allows consuming several beverages contained in the puzzle pieces simultaneously.

Abstract: A drinking straw for consuming two or three beverages simultaneously has a main body and three inlets in liquid communication with the main body. Each inlet is inserted into an isolated beverage compartment in a bottle or a separate glass. A cap is provided to close off one of the three inlets in order to consume only two rather than three beverages simultaneously.

Abstract: A beverage bottle for simultaneously dispensing three beverages without mixing the beverages inside the bottle has a spiral-shape divider forming three compartments defining spiral paths for the beverages through the bottle and preventing the beverages from mixing inside the bottle.

Abstract: An automatic pet door for large pets is installed in a hinged door and is actuated by a magnet worn by a pet. Unintended openings of the automatic pet door caused by the Earth's ambient magnetic field when the hinged door is moved are prevented by a system that includes a microelectromechanical systems gyro. A counterweight system allows the use of a relatively small and inexpensive electric motor to actuate the automatic pet door.

Abstract: A gyro-stabilized automatic pet door is installed in a hinged door and is actuated by a magnet worn by a pet. The automatic pet door prevents unintended openings caused by the Earth's ambient magnetic field that may trigger a magnetic detector that responds to the magnet worn by the pet. A microelectromechanical systems gyro disposed on the hinged door generates a signal in response to a movement of the hinged door that engages a lockout timer overriding the signal from the magnetic detector and preventing the pet door from opening.

Abstract: A socket caddy comprising either a vertical panel with pins holding sockets by way of the force of gravity, without friction with the pins. A base comprising a shallow storage box provides storage for socket ratchets and socket ratchet extensions.

Abstract: A tent-shaped socket caddy with pins holding sockets by way of the force of gravity, substantially without friction with the pins. A base with a shallow storage box provides storage for socket ratchets and socket ratchet extensions.

Abstract: An automatic pet door system is disclosed. The automatic pet door system has a rectangular frame mounted between studs of a wall defining a passage for entry and exit of a pet. A door slidably moves within the frame between a lower closed position for closing the passage and an upper open position for opening the passage. The door is lifted by a drive means having a motor pulling a cable attached to the door. The motor is energized by a control means in response to a signal received from a magnetic transmitter worn by a pet when the pet approaches the door. A locking means prevents movement of the door upwardly from the closed position unless the door is moved by way of the drive means.

Abstract: An automatic pet door apparatus includes a frame having a parallel-spaced pair of rigidly connected columns for mounting vertically oriented between wall studs, a lower portion of the frame defining a doorway passage between opposite sides of the walls; a door vertically movable in the frame between closed and open positions; a driver supported by the frame and coupled to the door for lifting the door from the closed position to the open position in response to a motor signal; a radiation transmitter for wearing by the pet and operable for producing a predetermined transmitter signal; a transducer located proximate the frame for producing a transducer signal in response to the transmitter signal when the pet approaches the frame from one side of the wall; and a controller responsive to the transmitter signal for activating the motor signal, whereby the door is raised by the driver, the door opening by sliding within the wall.
