Abstract: An telescopic ladder for a vehicle. The telescopic ladder comprises a first ladder section and a second ladder section, with each ladder section comprising a front portion and a rear portion and each including opposing sides extending from the front portion to the rear portion. The second ladder section is configured to telescopically extend from the first ladder section. The telescopic ladder further includes an extension support for facilitating the extension of the second ladder section from the first ladder section. The extension support includes at least one front roller assembly positioned adjacent to a front portion of the first ladder section, at least one pair of side roller assemblies positioned on the sides of the first ladder section, and at least one pair of cam-follower assemblies positioned on the sides of the second ladder section adjacent to the rear portion of the second ladder section.

Abstract: Methods and systems for adding a mark-up to a video stream. One method includes receiving, with a computing device, a video stream from an image sensor and metadata associated with at least one mark-up. The method also includes processing, with the computing device, the metadata to generate the at least one mark-up for the video stream and displaying the at least one mark-up overlaid on the video stream.
