Patent number: 8578113Abstract: A method for managing extents in a data storage system includes monitoring usage statistics for an extent residing on one or more powered-up storage devices. In the event the extent has not been accessed for specified period of time (as determined from the usage statistics), the method automatically compresses the extent and migrates the extent to an intermediate repository. Once the amount of data in the intermediate repository reaches a specified level, the method migrates the extent from the intermediate repository to one or more normally powered-down storage devices. If I/O is received for the extent while it resides in the normally powered-down storage devices or the intermediate repository, the method automatically migrates the extent from the normally powered-down storage devices or the intermediate repository to the normally powered-up storage devices. A corresponding apparatus and computer program product are also disclosed.Type: GrantFiled: April 16, 2012Date of Patent: November 5, 2013Assignee: International Business Machines CorporationInventors: Dale Howard Anderson, Philip Matthew Doatmas, Michael Robert Groseclose, Paul Anthony Jennas, Larry Juarez, Brian Sean McCain, David Montgomery, Jason Lee Peipelman, Joshua Marshall Rhoades, Todd Charles Sorenson

Patent number: 8260483Abstract: The present invention provides a guidance, navigation, and control method and system for an underground mining vehicle that allow said vehicle to be taught a route by a human operator and then have it automatically drive the route with no human intervention. The method works in three steps: teaching, route profiling, and playback. In the teaching step the vehicle is manually driven by a operator along a route which can consist of an arbitrary sequence of maneuvers including tramming forwards, switching directions, tramming backwards, turning, or pausing movement. During this phase raw data from vehicle-mounted sensors including odometric sensors and rangefinders are logged to a file throughout teaching for later processing. During the (offline) route profiling step, the raw data in the log file are processed into a route profile, and a profile of desired speed as a function of distance along the path.Type: GrantFiled: August 12, 2011Date of Patent: September 4, 2012Assignee: MacDonald, Dettwiler & Associates IncInventors: Timothy D.
