Publication number: 20230262899Abstract: An apparatus for mounting on a circuit board is provided. The apparatus may include a circuit board mount packaging and a battery. The circuit board mount packaging may include a cavity, a first internal lead, and a second internal lead. The first internal lead may be connect to a first external pin and the second internal lead may be connected to a second external pin. The battery may be disposed within the cavity of the circuit board mount packaging. The battery may comprise an anode and a cathode. The anode may be wire bond connected to the first internal lead and the cathode may be wire bond connected to the second internal lead.Type: ApplicationFiled: December 16, 2022Publication date: August 17, 2023Inventors: Konstantinos Gerasopoulos, Jason E. Tiffany, Seppo J. Lehtonen, Vanessa O. Rojas, Spencer A. Langevin, Bing Tan

Patent number: 11067449Abstract: A multispectral imager includes processing circuitry, an illumination assembly, a detector assembly, and a focusing assembly. The illumination assembly includes an array of illumination elements controlled by the processing circuitry to illuminate a scene. The detector assembly includes a detector array controlled by the processing circuitry to capture images from the scene at different wavelengths. The focusing assembly includes a lens and is controlled by the processing circuitry to adjust a focal point for the detector array. The processing circuitry generates and processes the images from the scene, taken at different wavelengths and focal points, combines the images to form a multispectral image cube for the scene, and determines a composition of an object within the scene based on a spectral profile of the multispectral image cube.Type: GrantFiled: September 5, 2020Date of Patent: July 20, 2021Assignee: The Johns Hopkins UniversityInventors: Jorge I. Nunez Sanchez, Rachel L. Klima, Scott L. Murchie, Seppo J. Lehtonen, John D. Boldt, Jacob M. Greenberg, Bryan J. Maas, Kyle L. Anderson, Trevor W. Palmer, Heidi E. Warriner

Patent number: 6881593Abstract: A semiconductor die adapter assembly includes a semiconductor die cut from a wafer, the die having an active surface including bond pads. A die adapter, also having bond pads, is bonded to the semiconductor die. Die-to-adapter connectors electrically connect the die bond pads to the adapter bond pads. Finally, adapter-to-substrate connectors electrically connect the adapter bond pads to a device substrate. Having bond pads on the die adapter eliminates the need to break and remake the electrical connections to the original bond pads on the die during burn-in testing of the die.Type: GrantFiled: May 31, 2002Date of Patent: April 19, 2005Assignee: The Johns Hopkins UniversityInventors: Binh Q. Le, Ark L. Lew, Harry K. Charles, Jr., Paul D. Schwartz, Seppo J. Lehtonen, Sharon X. Ling

Patent number: 6733823Abstract: A method of electrolessly gold plating copper on a printed circuit board (PCB). Starting with a copper patterned PCB, steps include: clean with ultrasonic agitation with the PCB initially oriented vertically and gradually moved to a 45° angle; rinse; sulfuric acid bath with ultrasonic and mechanical agitation; rinse; another sulfuric acid bath with ultrasonic and mechanical agitation; plate the copper with palladium with ultrasonic agitation with the PCB initially oriented at a 45° angle and flipped half way through to opposing 45° angle; rinse; post dip in sulfuric acid; rinse; electrolessly nickel plate with mechanical agitation; rinse; nitrogen blow dry; visual inspection for nickel coverage of the copper; hydrochloric acid bath with manual agitation; rinse; if full nickel coverage was not achieved, repeat preceding steps starting with second sulfuric acid bath; gold flash plate to establish a first layer of gold; rinse; autocatalytic gold plate; rinse; and nitrogen blow dry.Type: GrantFiled: April 2, 2002Date of Patent: May 11, 2004Assignee: The Johns Hopkins UniversityInventors: David M. Lee, Arthur S. Francomacaro, Seppo J. Lehtonen, Harry K. Charles, Jr.
