Abstract: Disclosed is a deep storage slot with a constant spring force comprising a storage slot housing defining a cartridge cavity and a cartridge opening, wherein the cartridge cavity is configured to store a plurality of cartridges in depth. Also disclosed is a constant force spring comprising a rolled, pre-stressed strip that exerts a constant force to resist uncoiling, the constant force spring having a first end affixed to the storage slot housing within the cartridge cavity to direct the constant force towards the cartridge opening, and at least one retention feature configured with the storage slot housing to hold at least one of the plurality of cartridges within the cartridge cavity against the constant force.

Abstract: An automated storage library structure, a structure of at least one robot operating within the automated storage library, and a method of connecting the robot to test equipment to facilitate testing. The robot is operative to move about the automated storage library on a guide structure. The test equipment is disposed in a diagnostics center associated with the automated storage library. Communication between the robot and the diagnostics center is provided through a main connector, disposed adjacent to the guide structure at a predetermined position and electrically connected to the diagnostics center, and a test connector mounted on the robot's chassis and electrically connected to the robot's electronics. A second robot may be used to support testing of a sick robot.

Abstract: A case stores CDs in a drawer which slides out from between an upper cover and a lower cover. The drawer has a handle projecting forwardly from the covers and which can be easily gripped by a user. A CD retainer in the drawer has a lip which grips a CD by snap-fitting over a side edge of the central aperture of the CD. The grip is released by the user simply pressing a push button, causing longitudinal movement of the retainer because it is on an arm extending between the button and a resilient anchorage.
