Abstract: A movie theater headset accessible by access codes which are unique for the movie for an additional cost when the ticket is purchased for the movie at movie theaters. Within the theater or venue the audio portion of the movie is transmitted electronically, either wirelessly or on a wired network, and the headset allows the user to hear the transmission only when the access code is entered. The headsets may be rented or purchased at the theater or venue. Electronic stores may also sell the headsets, or conversion kits for existing headsets, which permit the use of the access codes for movies.

Abstract: A back-up camera system for a towed trailer captures video feed behind the trailer. The system is comprised of a video camera, a monitor, and a control unit which provides an operating switch. The camera is mounted on the rear surface of the trailer and captures video feed behind the trailer. The camera transmits the video feed by wire to the control unit located in the cabin of the vehicle. The control unit transmits the video feed wirelessly to the monitor that displays the video feed to the user. The operating switch enables the user to activate the camera and control unit in order to see behind the trailer while driving, backing up, or parking.
