  • Paint can shelf for extension ladders
    Patent number: 9045940
    Abstract: A paint can shelf attaches to a sliding extension ladder fly section. The shelf includes two parallel arms which reach through hollow rungs of the sliding extension ladder fly section, whereby the shelf is raised and lowered with the sliding extension ladder fly section. Slides are attached to the arms on each side of the sliding extension ladder fly section and include low friction surfaces facing the fixed extension ladder section. The slides allow somewhat loose tolerances in the engagement of the arms with the ladder preventing the ladder sections from binding when the ladder is extended or lowered.

  • ONBOARD CONTROLLER FOR MULTISTATE WINDOWS
    Publication number: 20150049378
    Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.
