A new internal fixation device was applied to 41 proximal tibial osteotomies to ensure against loss of postoperative correction. An oblique osteotomy was stabilized by two screws and a five-hole one-half tubular plate. Thirty-six patients with 41 proximal tibial osteotomies were reviewed for an average roentgenographic follow-up time of 22.6 months (range, six to 48 months) with no loss of corr...

Introduction An important part of color reproduction is the rendering of colors onto display devices [1], where the colors may be spot colors (e.g., tints) or the colors of a digitized photograph. Display devices, such as monitors and printers, are capable of showing only a subset of all perceivable colors; this subset is called the device color gamut. Colors subjected to a reproduction system ...

A transportable high stable reference AD device was designed and realised for a comparison of systems for testing a dynamic quality of ADCs or AD modules two years ago. In spite of the fact that several comparative measurements were successfully executed, some limitations and imperfections were found out. Therefore a new innovated version of the device was designed and developed based on existi...

PA Rule Targets Smokestack Pollution In July 2011 the U.S. EPA finalized the CrossState Air Pollution Rule to reduce SO2 and NOX emissions from power plants using available emissions control technologies. SO2 and NOX contribute to ground-level ozone and fine particle pollution and often cross state lines, ending up far from their provenance. The rule is projected to achieve up to $280 billion i...

The effectiveness of primary and secondary authentication systems on mobile devices leaves room for improvement. Device manufacturers provide security features which require users to memorize long, complex passwords and/or provide biometric information. These approaches have drawbacks which make their continued usage untenable. Users are already inundated with passwords and regularly forget ans...

Implantable cardioverter-defibrillator (ICDs), cardiac resynchronization (CRT) and combination (CRT-D) therapy have become an integral part of the management of patients with heart failure with reduced ejection fraction (HFrEF). ICDs treat ventricular arrhythmia and CRTs improve left ventricular systolic function by resynchronizing ventricular contraction. Device therapies (ICD, CRT-D), have be...

When partial or complete closure of a coronary artery occurs, angioplasty is commonly performed to reopen the artery. However, the frustration of laser and balloon angioplasty is that in many cases the plaque quickly accumulates to reclose the artery and this phenomenon is called restenosis. A device has been developed to deliver externally generated ionizing dose of pulsed x-ray irradiation to...

A device laboratory was designed to create a commanded disturbance to the Furuta inverted pendulum. This pendulum was modified by adding a second inverted pendulum coupled to the main one by means of a semi-rigid spring. The induced motion on the second inverted pendulum causes displacement of the center of mass of the system, producing a kind of perturbation similar to that presented on mobile...

This paper describes ThumbTEC, a novel general purpose input device for the thumb or finger that is useful in a wide variety of applications from music to text entry. The device i s made up of three switches in a row and one miniature joystick on top of the middle switch. The combination of joystick direction and switch(es) controls what note or alphanumeric character is selected by the finger....
