Single-DMD based solid-state volumetric true 3D display

True 3D display can provide more depth cues to viewers. Different from the 3D display developed by Light Space Company, a single-DMD based true 3D display consists of a UHP lamp, a color wheel, a hollow integrator, a relay system, a DMD, projection lens, folder mirrors, 20 LC shutters, and several control circuits. The speed of the color wheel and circuits are required to be very high. The final luminance is 237cd/m2. The color gamut is 69.7% of the NTSC standard and the color temperature is 5407K.

XML-based agent communications for plant automation

The agent communications are basis for agent coordination, cooperation, competition, and task-performing. Agent communication languages (ACLs) provide a high-level, flexible and general model for agent communications. XML is much more useful to integrate and exchange the information in the heterogeneous environment, which can be used to describe the task information, equipment information, etc. The information expressed in XML and wrapped inside the content of KQML message is transmitted between agents. The receiver agent can easily understand the intension of sender agent and get the attributes of the communicative acts. The combination of KQML and XML provides a possible solution for the heterogeneousness and interoperation of MAS.
