Abstract: An apparatus and method for stereoscopic 3D image projection and viewing using a single projection source, alternating polarization, and passive eyewear. This approach is applicable to frame sequential video created using existing 3D graphics APIs, as well as other video signal formats, and is compatible with existing digital light processor (DLP) technology for both front and rear projection systems. An alternating polarizer filter actuator in the form of a closed feedback loop is used to modulate the projected image. A preferred embodiment enables an existing DLP projection system to be enhanced with 3D capability.

Abstract: A peripheral device is coupled to a system bus of an apparatus via a system bus compatible cable, and transmits to an operating system a request to transmit to the output multiple image stream 3D video data and a request to access a video subsystem for monitoring a status of page flip signals. The peripheral device transmits sync signals to at least one output of the peripheral device representing the page flip signals detected in response to monitoring page flip signal status. The apparatus transmits the multiple image stream 3D video data to the output. The multiple image stream 3D video data is received at a stereographic projection apparatus input. Each stream data contains a plurality of frames. The stereographic projection apparatus comprises an alternating polarizing filter, synced with the alternately projecting images, for separately filtering images from each of the image stream 3D video data at different polarization angles.

Abstract: In a bi-directional, self-synchronous bus for communication between semiconductor devices, a logic delay is provided as a flag to a state machine control for indicating that the bus is making a transition from a low to a high state. The logic delay causes the bus to adaptively idle until the bus settles, making it amenable for a wide variety of bus sizes and topologies. In this way, oscillation of the bus is avoided without slowing the speed of the state machine clock.
