Patent number: 11508643Abstract: Methods and apparatus of forming a thermal interface with condensate are described. In an example, a device may be disposed in a test environment or a test apparatus. An amount of condensate may be accumulated on a heat sink to coat the heat sink with a layer of condensate. The coated heat sink may be disposed on the device, where the layer of condensate is directed towards the device, and the disposal of the coated heat sink causes the layer of condensate to spread among voids between the heat sink and the device to form a thermal interface that includes the condensate. A test may be executed on the device with the thermal interface comprising the condensate between the coated heat sink and the device.Type: GrantFiled: December 28, 2018Date of Patent: November 22, 2022Assignee: International Business Machines CorporationInventors: Mark D. Schultz, John Peter Karidis

Patent number: 8506566Abstract: An adjustable-length orthopaedic strut apparatus having minimal x-ray absorption, the capability to produce small length adjustments with minimal axial backlash, and a body devoid of exposed threads, the apparatus having an outer telescoping strut element, an inner telescoping strut element, a threaded drive element rotationally mounted inside the outer telescoping strut element and engaging threads inside the inner telescoping strut element, and an input gear-train arranged to produce fine adjustment of the strut length by generating rotation of the threaded drive element that can be smaller than the input gear rotation. A preferred embodiment also includes compliant preload structures for reducing axial backlash between all moving elements, and one or more locking pins which can be selectively disengaged to adjust the compressive stiffness of the adjustable length strut.Type: GrantFiled: July 30, 2008Date of Patent: August 13, 2013Inventors: John Peter Karidis, Peter Morris Stevens

Patent number: 8413004Abstract: A phase-change memory (PCM) includes a matrix of storage cells, including at least a first group with at least one cell. Each cell includes a phase change material having at least a first resistance value and a second resistance value, such that the first group can have an identical message encoded therein in at least a first way and a second way. The memory also includes a controller configured to encode the identical message in the at least first group the first or second way, based on which way causes the least amount of writing cost, given current levels of the group. Another embodiment of memory includes a matrix of storage cells. Each of the storage cells has at least two levels, such that each of the storage cells can have an identical message encoded therein in at least a first way and a second way.Type: GrantFiled: February 29, 2012Date of Patent: April 2, 2013Assignee: International Business Machines CorporationInventors: Michele Franceschini, John Peter Karidis, Luis A.

Patent number: 8202273Abstract: An orthopedic fixator for positioning a first element relative to a second element with precision and with controlled compliance which can be adjusted during the healing process. One embodiment comprises a first frame for attachment to the first element, a second frame attached to the first frame through a plurality of adjustable effective length struts, and a third frame for attachment to the second element, wherein the third frame is compliantly attached to the second frame. A preferred embodiment comprises adjustable length preload elements to apply unidirectional forces between the first and second frames so as preload the adjustable effective length struts and substantially reduce the positional tolerance. An alternative embodiment comprises adjustable spring elements allowing the compliance of the attachment of the third frame to the second frame to be adjusted at various points in the healing process.Type: GrantFiled: April 28, 2008Date of Patent: June 19, 2012Inventor: John Peter Karidis
