Publication number: 20240077308Abstract: A metrology system includes a radiation source, an adjustable diffractive element, an optical system, an optical element, and a processor. The radiation source generates radiation. The adjustable diffractive element diffracts the radiation to generate first and second beams of radiation. The first and second beams have first and second different non-zero diffraction orders, respectively. The optical system directs the first and second beams toward a target structure such that first and second scattered beams of radiation are generated based on the first and second beams, respectively. The metrology system adjusts a phase difference of the first and second scattered beams. The optical element interferes the first and second scattered beams at an imaging detector that generates a detection signal. The processor receives and analyzes the detection signal to determine a property of the target structure based on the adjusted phase difference.Type: ApplicationFiled: January 4, 2022Publication date: March 7, 2024Applicant: ASML Holding N.V.Inventors: Mohamed SWILLAM, Justin Lloyd KREUZER, Stephen ROUX, Michael Leo NELSON, Muhsin ERALP

Patent number: 11660466Abstract: The skin therapy device combines the mechanical stimulation and cleansing in the form of vibration with optical stimulation from LEDs. The device combines these two elements without sacrificing the effectiveness of either the mechanical cleansing/stimulation or optical stimulation by passing the light through the mechanical elements that are in contact with the skin. The light from the LEDs does not pass around the mechanical elements, such as around opaque brush fibers, but passes through the mechanical elements.Type: GrantFiled: September 3, 2021Date of Patent: May 30, 2023Inventor: Lloyd Nelson

Publication number: 20230148577Abstract: The fishing lure includes a head with a bell-shaped tip that collects water as the lure moves. The water is directed through channels, creating cavitation bubbles at the channel outlets. The body houses the electronics and weights. The body includes holes in the form of mock gills that allow water to enter. The water activates the electronics, causing the light to begin pulsing. The electronics include batteries and a light source—preferably an LED—with associated circuit board, within a waterproof shell or cover. In the preferred embodiment, a switch protrudes from the waterproof shell, the switch activated by water. The body also includes internal weights, the internal weights moving within channels within the body. The internal weights knock against each other within the channels, creating a clacking sound.Type: ApplicationFiled: November 12, 2021Publication date: May 18, 2023Inventor: Lloyd Nelson
