Patent number: 11011368Abstract: A microwave excited ultraviolet lamp system with a data logging and retrieval circuit and method for operating the same. The data logging and retrieval circuit stores operational data in a cache memory using a FIFO data storage protocol. The contents of the cache memory are periodically copied to a larger removable memory so that the removable memory contains a relatively long historical record of the system operational parameters. The data logging and retrieval circuit includes a data port configured to load the contents of the cache memory into an external device when the device is coupled to the data port. A second data port allows the external device to supply power to the data logging and retrieval circuit so that data may be retrieved when the internal power supply is malfunctioning. Data stored in the removable memory may be protected so that it may only be accessed by authorized personnel.Type: GrantFiled: December 5, 2014Date of Patent: May 18, 2021Assignee: Nordson CorporationInventors: James M. Borsuk, James M. Khoury, Edward C. McGhee, James C. Smith

Patent number: 10410819Abstract: A system, method, and computer program product for optimizing the cooling of a UV bulb during a UV irradiation process is described. A power level in which to operate the UV bulb is received. In addition, a particular type of UV bulb being used in the UV irradiation process is received. Thereafter, at least one optimal UV cooling parameter that corresponds to the power level and the type of UV bulb is retrieved from a UV source parameters database. At least one control signal is then sent to a cooling device that is based on the retrieved optimal UV cooling parameter, and the control signal instructs the cooling device to cool the particular type of UV bulb according to the retrieved optimal UV cooling parameter during the UV irradiation process.Type: GrantFiled: April 28, 2015Date of Patent: September 10, 2019Assignee: Nordson CorporationInventors: James M.
