Abstract: A system includes a clamp that includes a first arm, a second arm, and a threaded rod coupled to the first arm and the second arm. The threaded rod is configured to be substantially vertical when the clamp is clamped to the static structure. The clamp is configured to, while the user on a ground surface and in response to the nut being rotated about the threaded rod, a first jaw is urged towards a second jaw such that the static structure is clamped between the first jaw and the second jaw. The system further includes a first bracket configured to be releasably affixed to an upper portion of a first side rail of a base station of an extension ladder, and a second bracket that is configured to be releasably affixed to a lower portion of the first side rail of the base station of the extension ladder.

Abstract: Techniques are provided for controlling arrangement of content (display elements) on a display presented to a user on a device. A set of display elements is received from a server. A primary tier and one or more secondary tiers are populated with display elements from the set of display elements according to a default pattern to establish an arrangement of the display elements. Interactions of the user with the display elements are monitored, wherein information obtained from monitoring is stored locally on the device. A level of interest of the user for the display elements is inferred based on the interactions. The arrangement of the display elements is updated with regard to the primary tier and the one or more secondary tiers to correspond to the level of interest of the user.

Abstract: An insertion tool for an intraocular lens including a hollow barrel, a rigid annular tube extending from the distal end of the barrel, the stylet for reciprocating within the barrel and the rigid tube, an actuator extending through the side wall of the barrel and connected to the stylet to permit the user to move the stylet back and forth within the barrel. A paddle is attached to the distal end of the stylet. The intraocular lens is loaded into the paddle and then the paddle and the lens are retracted into the rigid tube for insertion into the eye through a small incision. The paddle unfolds the lens as it is retracted into the tube. When the distal end of the instrument is placed into the eye, the paddle and lens are ejected from the tube so that the lens may be deposited within the eye.
