  • Publication number: 20240012330
    Abstract: A roll-to-roll computed axial lithography system includes an optical illumination system; an optical modulation system to receive light from the optical illumination system and to output an illumination pattern of light; and a web-handling system to receive and transport a web having a photosensitive material layer such that a portion of the web will be in an optical path of the modulation system. The web-handling system includes a development module to render three-dimensional structures from the layer exposed to the illumination pattern of light. The illumination pattern of light provides predetermined three-dimensional regions within a bulk of the layer that are exposed beyond a photo-responsive threshold for the photosensitive material providing volumetric patterning.

  • Patent number: 11809161
    Abstract: A system for determining a light intensity field for use in manufacturing a 3D object from a volume of material. The system receives a 3D specification of a 3D geometry for the 3D object that specifies voxels within the volume that contain material that is to be part of the 3D object. The system employs a cost function for effectiveness of a light intensity field in manufacturing the 3D object. The cost function may be an adjoint of an Attenuated Radon Transform that models an energy dose that each voxel would receive during manufacture of the 3D object using the light intensity field. The system applies an optimization technique that employs the cost function to generate a measure of the effectiveness of possible light intensity fields and outputs an indication of a light intensity field that will be effective in manufacturing the 3D object.

  • Publication number: 20150021054
    Abstract: A system for providing an automatic fire extinguishing system including a tank filled with an extinguishing agent with a targeting system with independently mounted targeting servos and targeting gimbal to position an emitter. A microcontroller provides control signals to the targeting servos and an actuation valve. A plurality of temperature sensors electrically connected to the microcontroller send temperature data to the microcontroller which calculates target angles and sends the target angle to the targeting gimbal. The emitter is positioned by the targeting servo positioning the targeting gimbal armatures to the target angles. The microcontroller compares sensor temperature data a predetermined temperature value and sends an open signal to the actuation valve when a sensor temperature data is greater than the predetermined temperature value. The extinguishing agent flows from the tank to the emitter, where it is discharged.
