Abstract: A system for plant illumination that may be installed in or made as part of a planting pot. The system employs a string of illuminable fixtures each having an illumination source. The fixtures may be operated on low voltage that steps down through a transformer and may employ an ambient light sensor. The system may incorporate light globes that protect the illumination sources and may incorporate a transparent color to provide colored light. Light shields may be employed to direct the light from each illumination source. A splashguard may be employed and placed between the illumination source and its respective socket to prevent water from entering the socket. The container may be formed with two walls to protect the wiring being disposed there between.

Abstract: An electric brake caliper includes a ball screw apparatus having a cup-shaped ball screw including an annular cylindrical sidewall disposed about a rotational axis and closed at one axial end thereof by an end wall joined around an entire periphery thereof integrally with the sidewall. The end wall is adapted to form a carrier for operatively supporting at least one planetary gear. The ball screw apparatus also includes a ball screw nut operatively engaged with the ball screw. The annular cylindrical sidewall of the ball screw also defines an axial length of the ball screw and a ball track extending about the sidewall along the axial length of the ball screw from starting point that is adjacent to, but axially spaced from, the closed end of the ball screw. The ball track further includes a ball return track.
