Publication number: 20230182199Abstract: A smart trim die assembly for providing multiple internal operations during a stroke. The smart trim die assembly (10) comprises a first die (12), a second die (14), and a cavity (20) formed between the first die and second die. A plurality of sensors (22) are located between the first die and the second die for measuring the distance therebetween during a stroke. A series of tools are integrated into one of the first die or second die and each perform one of trimming, piercing, dimpling, and tapping operations. The smart trim die assembly further includes a processor (210) and a memory device (214) for receiving readings from the sensors. The memory device further contains instructions that, when executed by the processor, cause the processor to, in response to the sensor reading a predetermined distance, instruct the series of tools to perform one or more of the operations.Type: ApplicationFiled: May 6, 2020Publication date: June 15, 2023Inventors: Wally KROEGER, Joyce LIU, Owen LI, Lee ZHAO, Les SHUMAN

Publication number: 20220258277Abstract: The invention relates to apparatuses and correspondent method of laser beam processing for various materials with strong light absorption and scattering. The apparatuses can be used for medical no incision laser surgery, long distance underwater or atmosphere light communication, less attenuation light energy delivery in optical turbid media, and so on. This invention is a new use of the imaging method using multiple beam interference to create destructive interference in the beam propagation path to reduce the illumination light intensity and so to reduce absorption and scattering of the materials, and to create constructive interference to produce high composite light intensity which forms an inner light layer to illuminate, process the inner object in the materials. The apparatuses are practicable and have great performance.Type: ApplicationFiled: February 12, 2021Publication date: August 18, 2022Inventor: Joyce Liu
