Abstract: The present disclosure generally relates to techniques for presenting operations in a presentation. A technique is provided for allowing a user to insert media items on consecutive slides. During a presentation mode, the media items are determined to be two instances of a same media item, and matched such that the media item plays continuously across multiple slides. Another technique is provided to allow a user to utilize a user input to override a linearly-defined set of actions within a presentation. Another technique is utilized to temporarily select a visually obstructed object in a graphic editing interface such that the visually obstructed object may be manipulated during the temporary selection mode.

Abstract: A simple yet reliable apparatus is disclosed for dissipating sudden impacts or applications of force. Sudden impacts are dissipated through the sequential shearing of rods or pins anchored perpendicularly to the incoming force and through the compression and evacuation of gel through holes or valves in a cylinder. By varying the diameter and length of the cylinder, pistons, the number size and composition of shear pins, the number and size of restriction holes and or the amount of gel, the system can reliably dissipate impacts within predetermined limits.

Abstract: Disclosed herein is a holder for use with trailer equalizer spring bars which serve to distribute the forces that occur when the tongue weight is applied to a towing vehicle hitch, for example. The holder for use when the spring bars are not being deployed include an outwardly angulated cylinder fastened to a tongue of the trailer oriented to receive a downwardly extending segment of the spring bar at one extremity thereof, and at the extremity remote therefrom is a chain that is part of the equalizer spring bar. The chain therefore is used to lock the equalizing spring bars with an integral lock on the existing trailer tongue.
