US Patent:

6688965, Feb 10, 2004
Filed:

Nov 27, 2002
Appl. No.:

10/306371
Inventors:

Martin Joseph Crippen - Apex NC
Jason Aaron Matteson - Raleigh NC
Brian Alan Trumbo - Apex NC
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H05K 500
US Classification:

454184, 361695
Abstract:

An air moving system such as a fan or blower system includes a back flow damper that functions in two orientations; non-inverted and inverted. First and second âendâ baffles are pivotally attached at opposite ends of the damper, and three âmiddleâ baffles are pivotally attached between the two end baffles. When the air moving system fails in the non-inverted orientation, the first end baffle and the three middle baffles are gravity operated to close off the air outlet to prevent the back flow of air, and the second end baffle pivots away from the outlet. When the air moving device fails in the inverted orientation, the second end baffle and the three middle baffles operate to close off the air outlet, and the first end baffle pivots away from the outlet. The three middle baffles are pivotally coupled to a connecting rod, which prevents the inadvertent jamming of baffles.

Filed:

Nov 27, 2002
Appl. No.:

10/306302
Inventors:

Martin Joseph Crippen - Apex NC
Jason Aaron Matteson - Raleigh NC
Brian Alan Trumbo - Apex NC
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06F 120
US Classification:

361687, 361683, 361695, 16277
Abstract:

A server blade system includes a plurality of slots for receiving server blades. The system includes an air moving device to move air through each of the server blades installed in the system. When one of the server blades is removed, a bypass damper rotates into the empty slot to obstruct the flow of air through the slot. The bypass damper is pivotally mounted within each slot and includes a torsion spring to move the damper into the obstruction position. Two hinge pin mounts, which are âUâ shaped in cross section, provide a snap fit for two hinge pins positioned at one end of the bypass damper. A spring mounting pin is positioned between the two hinge pins and a torsion spring is mounted over the spring mounting pin.

Appl. No.:

10/300058
Inventors:

Jason Aaron Matteson - Raleigh NC
Martin Joseph Crippen - Apex NC
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H05K 720
US Classification:

361700, 361699, 361707, 361709, 257714, 257715, 257722, 174 151, 174 152, 174 161, 165 803, 165 801, 165185
Abstract:

The capability of an assembly to transfer heat from a semiconductor package source is enhanced while a reduction in the space required for effective operation is achieved. Bodies of fins defining tubular channels are affixed to oppositely facing surfaces of a rectilinear body which is adapted to receive heat from a semiconductor package.

Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G06F 120
US Classification:

361724, 3122232, 165 804, 4399281
Abstract:

The functionality of a blade is expanded by the installation of an expansion unit including expansion components. The blade and expansion unit are provided with connectors allowing the blade components to access and utilize the expansion components when the connectors are mated. The blade and expansion unit include elements ensuring that the connectors align properly as the expansion unit is installed onto the blade, making the installation simple and quick. The blade and expansion unit also include elements securing the connection between the two, once made.

Filed:

Jun 30, 2003
Appl. No.:

10/610303
Inventors:

Martin Joseph Crippen - Apex NC, US
Jason Aaron Matteson - Raleigh NC, US
William Joseph Piazza - Holly Springs NC, US
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

F24F007/00
US Classification:

236 493, 62178, 622592, 361696
Abstract:

Methods, systems, and media for thermal analysis are disclosed. Embodiments of the invention receive temperatures associated with elements of a system. The temperatures received are dependant upon airflow and heating patterns of the elements. Differences between the temperatures received and expected temperatures are detected. Potential airflow and heating patterns associated with a thermal problem are then determined, the potential airflow and heating patterns being substantially consistent with the temperatures received, to identify a root cause of the thermal problem as a probable source of the differences. More specifically, embodiments collect temperature readings from temperature sensors within an enclosure of the system; identify and upward temperature gradient or temperature that exceeds a threshold temperature; and select a failure scenario associated with a root cause of a thermal problem that is similar to the thermal problem described by the temperature readings collected.
