  • Jetting devices with acoustic transducers and methods of controlling same
    Patent number: 11065868
    Abstract: A jetting device configured to jet one or more droplets of a viscous medium through a nozzle may include an acoustic transducer configured to emit an acoustic signal that transfers acoustic waves into at least a portion of the viscous medium located in a viscous medium conduit a viscous medium conduit configured to direct a flow of the viscous medium to an outlet of the nozzle. The acoustic signal may be an ultrasonic signal. The acoustic signal may adjust one or more rheological properties of the viscous medium, based on acoustic actuation. The acoustic transducer may be implemented by an actuator of the device that is configured to move through an eject chamber to cause viscous medium to be jetted through the outlet of the nozzle as one or more droplets.

  • Jetting devices with energy output devices and methods of controlling same
    Patent number: 11040531
    Abstract: A jetting device configured to jet one or more droplets of a viscous medium through the outlet of a nozzle includes an energy output device. The energy output device is configured to direct a quantum of energy into at least a portion of the volume of the viscous medium jetted through the outlet to control a breaking of the droplet from the nozzle. The energy output device may include an acoustic transducer or a piezoelectric material or a laser emitter or a heater.

  • Aperture stop assembly for high power laser beams
    Patent number: 7085076
    Abstract: An aperture stop assembly for use in an electromagnetic radiation system may include an aperture stop made of a material at least partly transparent to an applied electromagnetic radiation. At least a portion of the aperture stop may be formed at an edge of an aperture to deflect electromagnetic radiation into the at least partially transparent material.
