Abstract: A bicycle rack having two frame support prongs for supporting a tube of a bicycle frame. The frame support prongs are connected to a U-shaped tube at opposing parallel arms of the U-shaped support tube. The U-shaped support tube has a swivel support tube that is configured for swiveling engagement with a base support tube. The base support tube is connected to a base plate that is mountable on a substrate, such as a wall, vehicle, post, or other substrate. The frame support prongs are preferably removably attached to the U-Shaped support tube to allow for altering the orientation of the individual frame support prongs. The base support tube is preferably retained in the bracket by two pins positioned through the base support tube. Removal of a rearward pin allows the support frame to rotate downward into a storage position.

Abstract: What is disclosed is a litter box having a walkway on which an animal is forced to walk to get to of or into the litter. The litter box has a tray that is configured to hold litter. The tray has a base that is defined by a perimeter wall extending upward from the tray. The walkway is a grate walkway and positioned above the litter such that any litter on the animal's feet falls through the walkway and back to the litter. The walkway extends around the perimeter of the litter box to maximize the distance on which the animal must walk to enter or leave the litter box. An inner wall of the walkway defines a cavity in the litter box into which the animal jumps or steps from the walkway and to the walkway from the litter.

Abstract: Systems, devices, and methods for using an engine flywheel can provide both electric power output and braking of powered equipment. In particular, an engine flywheel can include a first rotor element configured to be coupled to a drive shaft for rotation with the drive shaft, one or more magnets carried by the first rotor element, the one or more magnets being configured for positioning with respect to a stator to generate electrical current upon rotation of the first rotor element, and a second rotor element configured to be coupled to the drive shaft for rotation with the drive shaft, the second rotor element including a braking surface configured for engagement with a braking element to slow the rotation of the second rotor element.
