Patent number: 11041500Abstract: A system for cooling a heat generating enclosure includes a first array of one or more fans of a first size and a second array of one or more fans of a second size, where the second array is in series to the first array. The system also includes a measuring unit configured to measure at least one process variable. The system also includes a control unit configured to control at least one of the fans in the first array or at least one of the fans in the second array based on the process variable, wherein the fans are controlled to achieve an optimization criterion.Type: GrantFiled: September 22, 2015Date of Patent: June 22, 2021Assignee: International Business Machines CorporationInventors: David Barron, Rachael C. Freitas, Howard V. Mahaney, Benjamin W. Mashak, George Zacharakis-Jutz

Patent number: 11035371Abstract: A method of cooling a heat generating enclosure includes setting a speed of each fan in a first array of fans, wherein each fan in the first array of fans is a first size, is disclosed. The method further includes measuring a process variable. The method also includes calculating a cooling strategy based at least in part on the value of the process variable. The method further includes setting the speed of each fan in the first array of fans or the speed of each fan in a second array of fans, wherein the second array of fans is in series to the first array of fans and each fan in the second array of fans is a second size, and wherein the speed of each fan that is set in the first or second array is set to implement the cooling strategy.Type: GrantFiled: November 2, 2015Date of Patent: June 15, 2021Assignee: International Business Machines CorporationInventors: David Barron, Rachael C. Freitas, Howard V. Mahaney, Jr., Benjamin W. Mashak, George Zacharakis-Jutz

Patent number: 10267340Abstract: A fan assembly system includes two or more circular fans, each fan situated in a round fan assembly, where each fan can be situated in the round fan assembly in any orientation. The system also includes a concentrically symmetric connector for each circular fan, located in a center of each circular fan. The system also includes a latching mechanism for each circular fan, where the latching mechanism is wholly contained within a swept area of a fan blade of the circular fan. The circular fans are arranged in a staggered arrangement, and the staggered arrangement of circular fans increases a number of circular fans that can be placed in the fan assembly system compared to a non-staggered arrangement.Type: GrantFiled: February 24, 2016Date of Patent: April 23, 2019Assignee: International Business Machines CorporationInventors: David Barron, Rachael C. Freitas, Howard V. Mahaney, Jr., Benjamin W. Mashak, George Zacharakis-Jutz

Patent number: 10170875Abstract: The embodiments relate to an apparatus allowing for the insertion and removal of multiple like and/or unlike connectors simultaneously without requiring permanent connector modification. The apparatus includes at least a first housing and a second housing. The first housing receives a first connector and the second housing receives a second connector. The first housing has a first variable aperture and the second housing has a second variable aperture. The first aperture is adjusted by a first retainer to hold the first connector in the first housing. The second aperture is adjusted by a second retainer to hold the second connector in the second housing. The first housing has a first exterior wall sized to receive and secure a second exterior wall of the second housing to form an assembly of the connectors.Type: GrantFiled: August 23, 2016Date of Patent: January 1, 2019Assignee: International Business Machines CorporationInventors: Khajistha Fattu, Rachael C. Freitas, Murali Neralla, Madeline Vega, George Zacharakis-Jutz

Patent number: 10031050Abstract: Embodiments herein describe a universal test platform that includes a universal test station (UTS) coupled to a system under test (SUT) using respective adapters. The adapters include an interface subdivided into portions that are assigned to different data and power standards. In one embodiment, the UTS is coupled to a UTS adapter using a plurality of cables that transmits the different data and power signals between the UTS and the adapter. For example, the interface in the UTS adapter may include a plurality of pins or optical channels that are each coupled to one of the plurality of cables. The SUT is coupled to a SUT adapter which may have the same interface as the UTS adapter. However, the SUT may be coupled to only a sub-portion of the I/O elements in the SUT adapter, and thus, only some of the I/O elements are used when testing the SUT.Type: GrantFiled: October 13, 2016Date of Patent: July 24, 2018Assignee: International Business Machines CorporationInventors: Khajistha Fattu, Michael Fattu, Rachael C.
