Abstract: A portable animal containment device for confining an animal to a defined area. The portable animal containment device includes a flat and a correction unit. The flat is adapted to be portable and defines the area within which an animal is confined. The flat has an associated presence detector for detecting whether the animal is occupying the flat. When the presence detector indicates that the animal is not occupying the flat, a signal is transmitted to the correction unit by way of wireless communication. The correction unit is carried by the animal and administers a stimulus to the animal when the correction unit receives the signal from the transmitter. Consequently, when the animal moves beyond the boundary defined by the flat, it receives a stimulus, which encourages the animal to remain in the flat.

Abstract: Described is a pet gate device for generating a non-tangible electrical pet barrier and for generating a non-tangible electrical pet passageway. The pet gate device includes a signal generating device and a receiver. The signal generating device is adapted to generate at least two different signals, namely a barrier signal and a passageway signal. The signal generating device includes a transmitter for transmitting the generated signals. The receiver is adapted to receive the transmitted signals and to recognize whether the barrier signal or the passageway signal is being generated and transmitted. The receiver is adapted to administer a stimulus to the pet when the receiver recognizes the barrier signal. Conversely, the receiver is adapted to not administer a stimulus to the pet when the receiver recognizes a passageway signal.

Abstract: The invention is a golf training aid and a method of using the golf training aid. The face of the golf training aid is mirrored and permanently etched with several reference markings illustrating proper ball position, proper setup position, and proper club and body position at several points during the swing. The aid is marked for use with woods, irons, and the putter. In one embodiment of the invention, the reference markings include several lines and textual prompts. In another embodiment of the invention, the textual prompts and some of the lines are replaced by icons. The back of the golf training aid is flat, allowing it to sit flush on a practice surface, thus allowing the golfer to practice a golf swing with head down and eyes on the ball while simultaneously viewing his own image juxtaposed with markings for a proper swing. The aid is used by placing it on the practice surface along the target line and optionally securing it in position.
