Abstract: Ladders and ladder components are described herein, including multipurpose and adjustable ladders. In one embodiment, a ladder includes a first assembly having rails and rungs, a second assembly having rails and rungs, and one or more hinges coupling the first and second assemblies together such that the first and second assembly may be positioned relative to one another in at least a position or state and at least a second position or state. A top cap is coupled to the rails of the first assembly, such that when the first and second assemblies are in the first position, the rails of the second assembly do not contact the top cap. When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.

Abstract: A barrier movement assist system aids in the moving of a barrier, the barrier assist system comprising one or more support members; one or more assist devices operatively coupled to the one or more support members, wherein an assist device comprises: a rotational member; and a flexible member operatively coupled to the rotational member and operatively coupled to the barrier; wherein the barrier assist system is configured to aid in opening or closing of the barrier within a frame. A drive system is configured to open and close the barrier, wherein the barrier assist system is configured to aid in the opening or the closing of the barrier. The barrier assist system is configured to reduce an opening speed, reduce an opening acceleration, or increase an opening resistance of the barrier, and is configured to reduce a closing force at which the drive system is configured to close the barrier.

Abstract: There are disclosed embodiments for a paintball swab. For example, a disk is pivotably and slidably attached to the distal end of a rod so there is a proximal and distal limit along the rod. When the disk is at the distal limit, it is perpendicular to the longitudinal axis of the rod. When the disk is at the proximal limit, it is angled with respect to the longitudinal axis of the rod.

Abstract: Among other things, methods and apparatus regarding collection, dissemination and display of information concerning paintball loaders and markers are disclosed. A loader includes a heads-up display, electronic devices for gathering, storing and disseminating information, and an antenna for sending and receiving data. Wireless voice communications among paintball players is possible via associated headsets. There is also disclosed paintball equipment and methods for controlling both the firing and loading mechanism of paintball equipment. Current systems or mechanisms have individual and discrete electronic control systems for firing operations, e.g. located in the paintball gun itself, and loading operations, e.g. located inside the paintball loader. The present disclosure unifies the electronic control of said firing and loader operations into a single electronic circuit board located on either the paintball gun or paintball loader.

Abstract: An interactive record keeping system includes a display system, a user input device, an input-output interface and a controller. The controller is configured to receive user input data indicative of a user display preference and a known waypoint location from the user input device, receive aircraft data indicative of a current aircraft operating parameter and receive environmental data indicative of a current environmental condition, both correlating with the known waypoint location. The controller is further configured to calculate an aircraft performance parameter based on the received aircraft data; generate display data based on the calculated aircraft performance parameter, the received environmental data, and the user display preference; provide the display data to the display system; and store the calculated aircraft performance parameter and the environmental data in a memory.

Abstract: Among other things, there is disclosed a cylindrical device which is used to remove broken paintballs and other unwanted material from the barrel of a paintball marker or from other paintball equipment. Cylindrical cleaning devices currently known in the art are prone to separation and failure after use. The present disclosure includes structure such as barbs and/or openings, a snap-fit sleeve element, and/or one or more spacers to limit or prevent such failure. Structure for cleaning, including squeegee elements movable between an insertion configuration and a cleaning configuration, and other materials and configurations, are also disclosed.
