Patent number: 10641535Abstract: An ice-maker system may be operable in an ice-making mode and in an ice-harvesting mode and may include a working-fluid circuit and an ice mold. The working-fluid circuit may include a compressor, an expansion device, and an ice-making heat exchanger. The expansion device is disposed downstream of the compressor. The ice-making heat exchanger is disposed between the expansion device and the compressor along the working-fluid circuit. The ice mold includes a plurality of pockets configured to receive water from a water-supply conduit when the system is operating in the ice-making mode. The ice mold may be in a heat-transfer relationship with the ice-making heat exchanger. The ice mold may define a channel that receives a warming fluid from a warming-fluid-supply conduit when the system is operating in the ice-harvesting mode. The warming fluid is fluidly isolated from working fluid circulating through the working-fluid circuit.Type: GrantFiled: March 19, 2018Date of Patent: May 5, 2020Assignee: Emerson Climate Technologies, Inc.Inventors: Haithem Murgham, David Myszka, Kyaw Wynn

Patent number: 8999726Abstract: Disclosed is a spotter device and methods for the formation of microassays, biochips, biosensors, and cell cultures. The spotter may be used to deposit highly concentrated spots of protein or other materials on a microarray slide, wafer, or other surface. It may also be used to perform various chemistry steps on the same spots. The spotter increases the surface density of substances at each spot by directing a flow the desired substance (or a solution thereof) over the spot area until surface saturation is accomplished. The spotter may be loaded by well plate handling equipment. The spotter uses wells, microfluidic conduits, and orifices to deposit proteins, other biomolecules, or chemicals on a spot on, a separate surface. Each orifice is connected to two wells via microconduits. When the spotter contacts a surface, a seal is formed between the orifices and the surface. The same or different substances may be flowed across each orifice. Any number of orifices may be incorporated into a spotter.Type: GrantFiled: February 25, 2013Date of Patent: April 7, 2015Assignee: University of Utah Research FoundationInventors: David A. Chang-Yen, Sriram Natarajan, Josh Eckman, Bruce K. Gale, David Myszka

Patent number: 8210119Abstract: Disclosed is a spotter device and methods for the formation of microassays, biochips, biosensors, and cell cultures. The spotter may be used to deposit highly concentrated spots of protein or other materials on a microarray a slide, wafer, or other substrate. The spotter uses microfluidic conduits and orifices to deposit proteins, other biomolecules, or chemicals on a spot on a substrate. Each orifice is part of a fluid pathways that includes an inlet and outlet conduit. When the spotter contacts a substrate a seal is formed between the orifices and the substrate.Type: GrantFiled: July 6, 2005Date of Patent: July 3, 2012Assignee: University of Utah Research FoundationInventors: Bruce Gale, David Chang-Yen, David Myszka
