Abstract: Method and system of determining if a predetermined amount of time has passed since dispatch of a first one of the plurality of trackless vehicles onto one of a predefined plurality of intersecting paths. If the predetermined amount of time has passed, determining if a second one of the plurality of trackless vehicles was available for dispatch onto the predefined path or another predefined path. If the second trackless vehicle was available for dispatch, dispatching the second trackless vehicle, and if the second trackless vehicle was not available for dispatch, dispatching a third one of the trackless vehicles onto the predefined path or another predefined path. The predetermined amount of time may be calculated based on a time interval on which the trackless vehicles are dispatched onto the predefined plurality of paths.

Abstract: A system to transport a payload platform along a predefined path in an amusement facility, including a system controller to generate and transmit a timing signal and a propulsion platform, coupled to and supporting the payload platform, to traverse the predefined path in synchronism with the timing signal received from the system controller. The propulsion platform having an address corresponding to at least one of a plurality of individually addressed timing signals. The system may further include a plurality of entertainment devices positioned along the predefined path in an amusement facility, that likewise operate in synchronism with the timing signal received from the system controller.

Abstract: A programming interface for a media management application is described herein. The programming interface allows a media bundle to induce a media presentation at the media management application. More particularly, a media bundle can be provided at a client device, and the media bundle can include program instructions that at least in part use the programming interface to cause the media presentation to be provided at the client device. The media presentation can make use of digital media assets that are stored at a media library on the client device, that are stored within the media bundle, or that are remotely accessible to the client device. The media presentation can provide a multimedia experience for the user of the client device.
