Abstract: A rodent exercise system includes a rodent exercise ball having a cavity with an inner surface and an access door on an outer surface that is selectively openable for entry of a rodent. A ring-shaped housing defines a central aperture aligned along an aperture axis to rotatably support the ball so it rotates in response to movement of the rodent. The housing defines a first plane extending along its width and transverse to the aperture axis, and a second plane extending along its thickness and along the aperture axis. At least one leg is selectively attachable to the housing in a stored position, extending in the first plane, or in a standing position, extending in the second plane. In the standing position, first and second ends of the leg rest on a surface to support the housing in an upright orientation.

Abstract: The current disclosure is directed to an improvement on the exercise ball for rodents and other small animals that are kept as pets. The invention is a spherical enclosure that allows the pet to experience freedom of movement in a safe environment. This polymer plastic sphere allows small rodents to exercise while maintaining rodent health and providing improved ergonomics for the user. The ball consists of multiple parts: a bottom hemisphere, a top hemisphere and a door.

Abstract: The current disclosure is directed to a mobile environment for the transportation of hamsters, other small rodents, or small animals kept as pets. This mobile environment allows the user to easily carry the pet hamster on the go. This mobile environment is based on the idea of stacking multiple areas for the hamster to interact. The bottom portion serves as the hideout for the hamster, providing shade, a place to tunnel into bedding, and a place to have food that is easily accessible. Above the “hide-away” portion is the exercise wheel. This wheel sits horizontally and spins freely, providing an easily accessible form of exercise for the hamster. Lastly, the funneling form on the top of the mobile environment provides a means to attach a water bottle for hydration on the go.

Abstract: The current disclosure is directed to a carrier for an exercise ball for rodents and other small animals that are kept as pets. This plastic carrier allows the carrying and setting up of stationary, 360 degree, or omnidirectional spin of the exercise ball within a compact ring form factor. The carrier is intended for recreational use in the home, in backyards, or in pet friendly parks.

Abstract: Various embodiments of the present disclosure provide an antenna system including a first set of receive antenna elements and a second set of transmit antenna elements. Each receive antenna element is paired with one of the transmit elements. Paired receive and transmit antenna elements point in the same azimuthal direction, and the receive antenna element feeds its paired transmit antenna element. Each receive antenna element and each transmit antenna element has a phase center, and the phase centers of the receive and transmit antenna elements are all positioned substantially along the same axis. The receive and transmit elements are arranged in a phase-conjugate configuration such that, for each pair of receive and transmit antenna elements, those receive and transmit antenna elements are altitudinally spaced substantially the same distance from a plane through the antenna system.
