Patent number: 8370659Abstract: Systems and methods that may be implemented for time-based management of storage memory controller (e.g., RAID controller) backup battery life in information handling systems by limiting the backup battery system operation time in order to save energy, reduce the impact of leakage current, and prolong memory controller backup battery shelf life while at the same time meeting requirements of back-up time for storage/server applications. The disclosed systems and methods may be implemented, for example, by providing a battery system controller that implements a pre-set memory controller backup battery operation time, in combination with a hardware-controlled mechanism that extends backup battery system operation time by disabling one or more current leakage paths within the storage memory controller circuitry.Type: GrantFiled: September 21, 2009Date of Patent: February 5, 2013Assignee: Dell Products L.P.Inventors: Shane Chiasson, Anand Nunna, Clark C. Bruderer, Ligong Wang

Patent number: 6724554Abstract: A method of inhibiting inadvertent and unauthorized writing and reading of information to and from a storage medium comprises the steps of (a) writing a first code in a predetermined location on the storage medium, the first code being indicative of a first protection mode of the storage medium; (b) receiving a command to change the protection mode of the storage medium from the first protection mode to a second protection mode; and, in response to the command, (c) writing in the predetermined location on the storage medium, in place of the first code, a second code indicative of the second protection mode. A protection mode can inhibit writing to the storage medium, both writing and reading to and from the medium, or neither. Changing of protection modes can also be password protected.Type: GrantFiled: June 7, 2000Date of Patent: April 20, 2004Assignee: Iomega CorporationInventors: David G. Braithwaite, Clark C. Bruderer, Gregory M. Allen, David A. Thompson

Patent number: 6271980Abstract: The presence of a disk cartridge in a disk drive is detected by obtaining a measure of the load on the spindle motor of the disk drive and comparing that measure to a threshold value. The measure of load on the spindle motor may comprise (i) the time the spindle motor takes to spin-up to its full operating speed, (ii) the time the spindle motor takes to coast down to its operating speed from a first speed in excess of the operating speed, (iii) the voltage applied across the coils of the spindle motor, or (iv) the current drawn by the spindle motor.Type: GrantFiled: July 8, 1999Date of Patent: August 7, 2001Assignee: Iomega CorporationInventors: David M. Ginosar, Mark S. Thayne, Yiping Ma, Clark C. Bruderer

Patent number: 6144526Abstract: A disk cartridge adapted for insertion into a data storage device having an insertion opening, a spindle motor positioned to engage a hub of the disk cartridge, and a cartridge receiving stop having first and second receiving projections. The disk cartridge includes an outer casing having a top surface having a substantially flat middle region and angled peripheral regions; a substantially flat bottom surface defining an opening; a back wall having a rear peripheral edge; a front wall having a front peripheral edge; and side walls that each meet the front wall to form a plurality of non-square shaped front corners. When the disk is inserted into the data storage device, a first engaging projection formed on the front wall engages the first receiving projection of the cartridge receiving stop, a second engaging projection formed on the front wall engages the second receiving projection of the cartridge receiving stop, and the hub engages the spindle motor.Type: GrantFiled: March 12, 1998Date of Patent: November 7, 2000Assignee: Iomega CorporationInventors: David M. Ginosar, Mark S. Thayne, Yiping Ma, Clark C. Bruderer
