Radial self-propagation pattern generation for disk file servowriting
TL;DR: In this paper, a mechanism for servowriting on a storage medium of a storage device has been proposed, where at least one transition is written on a track of the storage medium, while servoing on other transitions previously recorded on the track, and a reference waveform is derived as a function of a closed loop response of the servo loop and a position error waveform.
Patent
Method and system for authenticating objects and object data
Timothy J. Chainer,Claude Greengard,Paul A. Moskowitz,Alejandro G. Schrott,Charles Tresser,Robert Jacob von Gutfeld,Chai Wah Wu +6 more
TL;DR: In this paper, a system and method for authenticating an image of an object, including at least one identifier associated with the object, a receiver for interrogating the identifier to produce identification information, a camera system for recording an image from the object including the identifier, and a composite generator for encoding the identification information from the receiver along with the image acquired by the camera system to produce composite data.

Server liquid cooling with chiller-less data center design to enable significant energy savings
Madhusudan K. Iyengar,Milnes P. David,Pritish R. Parida,Vinod Kamath,Bejoy J. Kochuparambil,David P. Graybill,Mark D. Schultz,Michael A. Gaynes,Robert E. Simons,Roger R. Schmidt,Timothy J. Chainer +10 more
TL;DR: In this paper, the authors summarized the concept design and hardware build efforts as part of a US Department of Energy cost shared grant, two year project (2010-2012) that was undertaken to develop highly energy efficient, warm liquid cooled servers for use in chiller-less data centers.
Patent
Method and apparatus for secure authorization and identification using biometrics without privacy invasion
Timothy J. Chainer,Bruce Kitchens,Stephane H. Maes,Marco Martens,Joseph D. Rutledge,Charles Tresser +5 more
TL;DR: A method and apparatus for authenticating (or identifying) a subject, includes using one or a plurality of biometric measurements for authentication (or identification) without any sharing of the subject's biometric data with a party requesting authentication as discussed by the authors.
Patent
Integrated chip carrier with compliant interconnects
TL;DR: In this paper, the authors defined the first coefficient of thermal expansion (CTE) of an electronic device as: at least one electronic chip comprising a first CTE; and a carrier including a top surface connected to the bottom surface of the chip by solder bumps.
