Patent number: 9850517Abstract: Biological cells in a liquid suspension are counted in an automated cell counter that focuses an image of the suspension on a digital imaging sensor that contains at least 4,000,000 pixels each having an area of 2×2 ?m or less and that images a field of view of at least 3 mm2. The sensor enables the counter to compress the optical components into an optical path of less than 20 cm in height when arranged vertically with no changes in direction of the optical path as a whole, and the entire instrument has a footprint of less than 300 cm2. Activation of the light source, automated focusing of the sensor image, and digital cell counting are all initiated by the simple insertion of the sample holder into the instrument. The suspension is placed in a sample chamber in the form of a slide that is shaped to ensure proper orientation of the slide in the cell counter.Type: GrantFiled: September 27, 2013Date of Patent: December 26, 2017Assignee: Bio-Rad Laboratories, Inc.Inventors: Tom McCollum, Paul Patt, Frank Shen, Daniel Y. Chu, Don Flory, Mike Griffin, Xin Heng, Eli Hefner

Patent number: 7686224Abstract: A diode-laser bar package includes two diode-laser bars mounted on a heat sink with slow-axes of the diode-laser bars aligned. Three spaced apart mounting bosses extend from the front of the heat sink. The package includes two cylindrical lens assemblies. Each lens assembly has an elongated cylindrical lens bonded to a rectangular mounting block. The cylindrical lenses are aligned with the diode-laser bars. Lateral faces of the mounting block are epoxy-bonded to lateral faces of the mounting bosses. Bonding is effected by injecting liquid epoxy between the faces to be bonded though holes extending through the mounting blocks from front to the lateral faces of the mounting blocks. The liquid epoxy is then cured to complete the attachment.Type: GrantFiled: August 30, 2006Date of Patent: March 30, 2010Assignee: Coherent, Inc.Inventors: David Schleuning, Paul Lovato, Mike Griffin, John McNulty
