  • Patent number: 11389853
    Abstract: The present disclosure discloses a device and a method for forming a metal plate by using a high-energy electric pulse to drive an energetic material. The device includes high-energy pulse discharge equipment, an intelligent robot arm control system, a vacuum pumping device, a hydraulic press, a forming die, positive and negative electrodes, an energetic rod, and liquid supply equipment. According to the present disclosure, energy of a metal wire is added to energy of an energetic material after energy release to implement high-rate forming of the plate. A discharge voltage of the high-energy pulse discharge equipment is reduced and a service life thereof is prolonged. The discharge equipment is triggered by the manufactured small-size electric pulse metal wire, thereby reducing a volume and costs of the equipment and miniaturizing the equipment to implement precise operating, forming, and intelligent integration with the robot arm control system.

  • Patent number: 7146070
    Abstract: Electro-optically operated transmitters containing a wave guide liquid crystal beam steering device in series of fine beam steering devices as well as electrically switchable mirror are disclosed. The wave guide beam steering device is constructed on a planar lightwave circuit that contains a plurality of liquid crystal switching elements intersecting a plurality of optical wave guides and one main wave guide that has a curvature for light propagation. The transceiver is capable of continuously steering multiple beams of light into separate independent directions with a field-of-regard close to 4?. The resulted optical transmitter device is motionless, polarization sensitive or insensitive, stable within the operational spectral region, and stable versus temperature. When an optical receiver is integrated, the transmitters become transceivers. The invention also includes the methods for manufacturing the wave guide beam steering device.
