摘要： A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.

摘要： An automatic camera steering control for directing video conferences including a communicator with a microphone and a voice activated LED emitter. Cameras receive an LED signal transmitted by the LED emitter and focus on the speaker associated with the activated LED emitter. A controller automatically selects and inserts into the video stream the audio and video of the speaker.
