Abstract: Certain embodiments involve an integrated content-production system. In one example, an integrated content-production system can include a video camera, an operator station, and a presenter station. The operator station can include a source control device communicatively coupled to a set of content sources and the video camera. The source control device can be used to switch among an output of the video camera and the set content sources for transmission of content to target devices. The presenter station can include a content display device communicatively coupled to the video camera and the set of content sources. The presenter station can also include a touchscreen device that presents a source-selection interface. The source-selection interface can have scrollable rows of interface elements for switching among the output of the video camera and the set content sources for transmission of content to one or more target devices.

Abstract: Wheelchair designs and enhancements are provided for use with conventional wheelchair designs. The designs and enhancements include first and second contoured folding seat panels that are hingedly mounted with respect to the wheelchair frame and that are offer interlocking functionality. The folding seats generally provide contouring in both front-to-back and side-to-side directions. Features are provided to prevent capture of objects between seat panels as they are brought into interlocking engagement. Pivotal footrests that offer enhanced stability in the form of lateral, front-to-back and up-down stability are provided In addition, axle and axle plate combinations are described that provide enhanced flexibility in relative positioning with respect to the wheelchair frame. The disclosed features and functionalities may be incorporated into wheelchair designs, either in whole or in part, to provide enhanced user interaction with the wheelchair.
