The Automated Transport and Retrieval System (ATRS) represents a technology-based alternative to van conversions for automobile drivers in wheelchairs. Rather than requiring dramatic, permanent, and expensive modifications to the host vehicle, ATRS employs robotics and automation technologies and can be integrated noninvasively into a standard minivan or sport utility vehicle. At the core of AT...

OBJECTIVE The objective was to determine if visual estimation of effort (VEE) during lifting tasks is accurate in classifying relative levels of exertion or distinguishing between incomplete lifts that may be potentially unsafe and incomplete lifts of "actors" feigning weakness. PARTICIPANTS A convenience sample of 117 health professionals and lay subjects participated in the study. METHODS...

Starting with a unit-preserving normal completely positive map L : M → M acting on a von Neumann algebra or more generally a dual operator system we show that there is a unique reversible system α : N → N (i.e., a complete order automorphism α of a dual operator system N) that captures all of the asymptotic behavior of L, called the asymptotic lift of L. This provides a noncommutative generaliz...

BACKGROUND To evaluate the effectiveness of the minimally traumatic midface lift approach in combination with the Wrinkle Severity Rating Scale (WSRS) criteria. METHODS From July 2007 to September 2009, 21 female patients underwent the minimal incision midface lift procedure. The procedure was mainly composed of a small arrow-like incision just superior to the top of the auricle, a fanlike su...

In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...

The electromagnetic acoustic transducer (EMAT), a non-contact NDT tool with large lift-off, is becoming an attractive method for detecting the cracks in the metal parts. However, the lift-off of the transducer has a direct effect on the feature that is used to characterize the defects. A detailed investigation on the relationship between the feature and the lift-off of the EMAT is crucial in th...

The lower-body lift, designed for patients with multiple lower-body contour deformities, uses a circumferential bikini-line incision to simultaneously lift relaxed trunk and thigh tissues. The author describes 2 lower-body lift procedures, focusing primarily on the high-lateral-tension abdominoplasty with transverse-thigh/buttock lift, which he developed in 1996. (Aesthetic Surg J 2001;21:355-3...

The needle lift and return timing of a CRDI (common rail direct injection) injector were investigated using an accelerometer and the Bosch injection rate measurement method. The Bosch method was used to measure the fuel injection rate shape when fuel was injected with several patterns. An accelerometer was mounted on the outside of the injector to catch the needle lift and return timing of the ...

On pipeline magnetic flux leakage (MFL) inspection, welds and debris are present in all pipelines and cause lift-off of the sensors and/or the magnetizer of the magnetic flux leakage inspection tool, and have the potential to affect the acquired magnetic flux leakage data. By adopting ANSYS software to simulate the effect of lift-off on the MFL signal. The results of this research indicate that...
