Publication number: 20240132342Abstract: A venthole of a micromechanical device is sealed with laser irradiation. A micromechanical device has a substrate, such as silicon. The substrate has an upper surface, and defines a venthole leading to a chamber that contains a device, and a trench extending downward from the upper surface and located offset from the venthole. A laser pulse is applied to the substrate at or within the trench. This causes a portion of the substrate located below the upper surface to melt and travel laterally to close off and seal the venthole laterally from beneath the upper surface.Type: ApplicationFiled: October 24, 2022Publication date: April 25, 2024Inventors: Bo CHENG, Holger RUMPF, Jens FREY, Charles TUFFILE, Stephanie KARG, Tobias Joachim MENOLD

Patent number: 10437079Abstract: Provided is an eyewear lens, including a lens substrate and an optical interference coating. The lens substrate is comprised of an optical material, and the optical interference coating is combined with the lens substrate and is stacked by the composition of high and low reflectivity materials. A predefined reflective appearance color will be formed by light getting through the optical interference coating. The lens substrate contains another filter on one side surface or both side surfaces or inside the lens substrate which is complementary to the light after penetrating the optical interference coating such that the overall transmittance light color remains neutral balance. Moreover, the overall transmittance spectrum of a lens uniformly filters the reflected visible light of objects. As such, a stylish reflective appearance color lens having neutral balance perspective visual tone and most colorful rendering effect of watching the scenery is achieved.Type: GrantFiled: December 14, 2017Date of Patent: October 8, 2019Assignee: HWA MEEI OPTICAL CO., LTD.Inventors: Charles Cheng, Chih Ming Chen

Patent number: 10032500Abstract: Methods and systems are described herein for determining if bit cell read or write rates require a refresh of the accessed or neighboring bit cells. The refresh of VLT memory bit cells that undergo a high frequency of page address read operations and write operations helps to maintain integrity of data stored in the VLT memory bit cells. The methods and systems determine, during each RAS cycle, if a rate of Page Address read operations or write operations exceeds a maximum rate across an interval, and conditionally cause a refresh operation if the rate exceeds the maximum rate. The methods and systems output a write back signal to cause a refresh of the associated VLT memory bit cells to prevent corruption of data stored in the associated VLT memory bit cells.Type: GrantFiled: October 7, 2016Date of Patent: July 24, 2018Assignee: TC Lab, Inc.Inventors: Adrian E. Ong, Charles Cheng

Patent number: 5945685Abstract: A glass disk substrate inspection tool uses a polarized laser beam that is directed to the first surface of the disk substrate at Brewster's angle and is then transmitted through the disk substrate to a light detector that generates a signal representative of the intensity of the light received. Because the light polarized parallel to the plane of incidence, i.e., the plane formed by the line of the incident beam and a line perpendicular to the surface of the disk substrate, is completely transmitted, there is no surface reflection at either the first or second surfaces of the disk substrate. The polarized beam is directed by a first rotating scanner to the input of a telecentric lens assembly that provides an output beam parallel to its optical axis as the beam is being scanned. The beam is then directed by a first fixed mirror to strike the first surface of the disk substrate at Brewster's angle as the beam is scanned along a line across the first disk surface.Type: GrantFiled: November 19, 1997Date of Patent: August 31, 1999Assignee: International Business Machines CorporationInventors: Wayne Isami Imaino, Anthony Juliana, Jr., Milton Russell Latta, Charles Cheng-Hsing Lee, Wai Cheung Leung, Hal Jervis Rosen
