Abstract: Systems and methods are described for a shoe sole for relieving pressure from a wearer's metatarsal heads. In one aspect, a shoe sole comprises a shoe outer sole comprising a shaft region, a ball region, and a toe region. The shaft region underlies metatarsal shafts of the wearer and comprises a first lower surface, the ball region underlies metatarsal heads of the wearer and comprises a second lower surface, and the toe region underlies phalanges of the wearer and comprises a third lower surface. The second lower surface is raised relative to the first lower surface and the third lower surface.

Abstract: A presence determination system comprising at least one motion sensor for detecting movement in a sensing area. The system is adapted to determine a plurality of properties associated with at least one movement detected by the at least one sensor preceding a period where no motion is detected by the at least one sensor. The plurality of properties of the movement(s) detected before the period where no movement is detected are compared with a profile in order to determine whether or not the sensing area is unoccupied. The profile may be representative of movement properties indicative of exiting a room.

Abstract: The illustrative embodiments described herein provide an apparatus and method for facilitating signal transmission using differential transmission lines. The apparatus includes a first differential transmission line. The first differential transmission line includes a first plurality of conductors. The first plurality of conductors includes a set of conductors. The apparatus also includes a second differential transmission line. The second differential transmission line includes a second plurality of conductors. The second plurality of conductors includes a first conductor and a second conductor. A first noise produced by the first conductor on the set of conductors is balanced by a second noise produced by the second conductor on the set of conductors. The first differential transmission line and the second differential transmission line facilitate signal transmission.

Abstract: A cylinder head of an internal combustion engine is provided with a cylinder head housing and with a divided camshaft bearing rail having a lower part, which comprises lower bearing blocks, and having an upper part, which comprises upper bearing covers. In addition, the cylinder head has a cylinder head cover. The upper part of the camshaft bearing rail is designed so that it is closed like a hood, in particular, in the area between the bearing covers.

Abstract: A testing system, particularly directed at contract workers, permits computer-aided instruction and testing at each of a plurality of testing sites. Different tests are created and administered for each of a plurality of work sites, which can be selected by the prospective contract worker. Whether the worker passed a particular site-specific test is stored in a database, which in turn is accessible by the work site management. The system has particular application to safety instruction and testing as mandated by the Occupational Safety and Health Administration.
