And we solve in 3D the unique position-of-wear variables required to order a state-of-the-art fully-compensated progressive lens and we're the only online company in the world that can do this.
13 With the improvement of technology in the past 30 years, actimeters have become more precise (with multiple piezoelectric accelerometers) and the position of wear has been diversified (wrist, chest, hip) in response to new applications.
Anthropologists learnt from the degree and positioning of wear and tear in Oetzi's joints that some Neolithic people, contrary to previous theories, spent most if not all their lives high in the mountains.
Recent studies have also established methods to ascertain global positions of wear patterns on CoCr femoral heads for computer-generated models simulating conventional polyethylene wear and liner positioning [ 6, 9].
In a subsequent statement, Wheaton College President Dr. Philip Ryken said, "The College has no stated position on the wearing of headscarves as a gesture of care and concern for those in Muslim or other religious communities that may face discrimination or persecution".
Looking at the wearing position of the trackers (wrist-worn for the Fitbit Flex, Jawbone UP, and Nike+ Fuelband and centrally worn, e.g. close to the pelvis or trunk, for the remaining devices), our results indicate that activity trackers worn close to the body exhibit a better validity than the wrist-worn activity trackers, especially during free-living conditions.
Motion sensors track the position of the wearer's head, then feed this data across an umbilical cord to a computer, typically a gaming P.C.
The position of maximum wear depth occurs at the central contact region and this is in close agreement with test results.
Thereafter, state robes were constructed in such a way that in many cases the rank and position of the wearer could be determined by the presence or absence or disposition of the black spots.
"The cut and cloth of clothes, as well as hats, hair, wigs and accessories, announced the social position of the wearer," Michael Snodin and John Styles, two curators at the Victoria and Albert Museum in London, wrote in their new book, "Design and Decorative Arts: Britain 1500-1900" (Harry N. Abrams).
