Abstract: A conveyor bed is provided that can include a conveyor frame, a roller frame and an adjustment mechanism. The adjustment mechanism can include a first wheel movable on a first rail and a second wheel movable on a second rail. A sled can be coupled to a bottom face of the roller frame, where an inner face of the sled is in contact with the first wheel and the first rail and an outer face of the sled is in contact with the second wheel and the second rail. An actuable component coupled to the sled, wherein the actuable component is configured to move the sled back and forth linearly along the first rail using the first wheel in response to rotation of the actuable component, wherein a movement of the sled rotates the second wheel and pivots the second rail to alter an angle of the roller frame.

Abstract: A coupling mechanism includes a pair of bracket and a spacer plate sandwiched in between the pair of brackets. Each bracket of the of brackets comprise a first cutout formed on a top face of each bracket of the brackets. A retainer bar coupled to the pair of brackets, wherein the retainer bar comprises a second cutout formed on a bottom face of the retainer bar and a flat top surface. The second cutout and the first cutout abut each other to form an opening, wherein the opening receives an axle of a conveyor roller.

Abstract: A user connected to a data network controls a parallel teleconference network by sending requests through the data network. The requests are validated against permissions granted to the user and an action associated with a request is performed at the teleconferencing network if the request is validated. A status for a teleconference hosted by the teleconferencing network may be sent when the action is performed or when other changes occur during the teleconference. A voice message also may be sent to a user that is affected by the action. In one aspect, the allowed actions are presented to the user through the data network. In another aspect, a graphical user interface for controlling the teleconferencing network is presented to the user through the data network.
