Patent number: 9075813Abstract: A mechanism for saving a snapshot of free space of a file system on persistent storage is disclosed. A method of the invention includes determining whether generation numbers stored in each of a free space cache inode of an on-disk free space cache of a block group, a free space cache item, and a free space cache header are valid, determining whether a checksum generated for a first page of the free space cache matches a checksum stored in the file system and associated with the free space cache, and adding entries stored in the on-disk free space cache to an in-memory free space cache for the block group kept in volatile memory of a computing device, wherein the on-disk free space cache is stored in persistent data storage indexed by a file system of the computing device.Type: GrantFiled: September 15, 2011Date of Patent: July 7, 2015Assignee: Red Hat, Inc.Inventor: Josef Michael Bacik

Patent number: 8815174Abstract: A sterilizer having a cassette for holding metal instruments or medical devices. The cassette includes a metallic container that defines a sterilization chamber. The container has at least one outer surface. A plurality of spaced-apart, elongated rails extend along the at least one outer surface of the container. Each of the rails includes a free, longitudinal edge wherein the edges of the rails lie in a first plane. An insulating shell encases the metallic container and the plurality of rails. An outer surface of the insulating shell lies in the first plane. A receiving unit includes a housing having an outer surface and an inner surface. The inner surface engages the edges of the rails and the outer surface of the insulating shell when the cassette is disposed within the inner housing. A plurality of spaced-apart elongated ribs extends along the outer surface of the housing.Type: GrantFiled: March 13, 2013Date of Patent: August 26, 2014Assignee: American Sterilizer CompanyInventors: Michael A Bacik, Peter J Buczynski, Francis J Zelina, Jeffrey C Robertson

Patent number: 7550122Abstract: A decontamination system for decontaminating an enclosure defining a chamber or region. The decontamination system includes an air bypass for introducing atmospheric air into the decontamination system and bypassing air to the atmosphere in response to system operating conditions. The air bypass allows increased airflow through the decontamination system during certain operating modes of the decontamination system (i.e., dehumidification and aeration phases), thereby reducing the amount of time needed to dehumidify and aerate the enclosure. The air bypass also facilitates the use of a high capacity dryer in the decontamination system.Type: GrantFiled: May 31, 2006Date of Patent: June 23, 2009Assignee: American Sterilizer CompanyInventors: Peter J.
