An illumination structure for generating specific directional light sources includes a substrate unit, a light-emitting unit and a lens unit. The substrate unit has at least one substrate body. The light-emitting unit has a plurality of light-emitting elements disposed on and electrically connected to the substrate body. The lens unit has a plurality of lens modules sequentially abutted against each other and disposed on the substrate body. Each lens module has a lens frame disposed on the substrate body and a plurality of protruding lens elements separated from each other by a predetermined distance and integrally formed on the lens frame, the protruding lens elements respectively correspond to the light-emitting elements, and each protruding lens element has at least one concave portion formed on a top side thereof and above each light-emitting element and at least two protrusion portions respectively integrally connected to two opposite sides of the concave portion.

Exemplary embodiments of method and apparatus are provided for resurfacing of skin that includes formation of a plurality of small holes, e.g., having widths less than about 1 mm or 0.5 mm, using a mechanical apparatus, thus avoiding generation of thermal damage as occurs with conventional laser resurfacing procedures and devices. The holes formed can be well-tolerated by the skin, and can exhibit shorter healing times and less swelling than conventional resurfacing procedures. The apparatus includes one or more needles adapted to remove a small portion of tissue when inserted into and withdrawn from the skin. The fractional surface coverage of the holes can be between about 0.1 and 0.7, or between about 0.2 and 0.5. The exemplary method and apparatus can produce cosmetic effects such as increases in collagen content, epidermal thickness, and dermal / epidermal junction undulations in the skin.

An imaging tomography apparatus, in particular an x-ray computed tomography apparatus, has two acquisition systems capable of rotating around a common rotation axis. Each of the acquisition systems has a radiator as well as a detector. The maximum measurement fields scanned by the two acquisition systems given rotation around the rotation axis are of different sizes, or can be adjusted to different sizes. In particular, the lengths of both detectors measured in the azimuthal direction—are of different sizes. The tomography apparatus can be fashioned to scan the entire body cross-section of an examination subject or of a patient with conventional temporal resolution, and to scan detail region, such as a heart region, with an increased temporal resolution or accelerated data acquisition rate in comparison to a device with only one acquisition system.

A damping arrangement for a blade (20) of an axial turbine, in particular a gas turbine, includes a damping element (17) which is arranged in a recess (16) in the blade aerofoil (10) of the blade (20) and frictionally dampens the vibrations of the blade (20). In such a damping arrangement, simplified manufacture and assembly and a reliable and effective function are achieved by the recess being configured as a cavity (16) extending in the radial direction through the inside of the blade aerofoil (10), the damping element (17) being inserted in the radial direction into said cavity (16).

A thin-film transistor substrate, including a substrate with an insulating surface, gate electrodes, lower electrodes of capacitors made of the same material layer as the gate electrodes, a first insulating layer, a channel layer of high resistivity semiconductor having a concave part, and a pair of low resistivity source / drain electrodes. There is also a second insulating layer formed on the first insulating layer. A first connection hole penetrates the second insulating layer and exposes one of each of the pair of the source / drain electrodes. A second connection hole penetrates the second insulating layer and exposes a connection region of each of the upper layers of the upper electrode above the lower layer. A pixel electrode is formed on the second insulating layer and is connected to one of the source / drain electrodes and the upper layer of the upper electrode of the capacitor via the first and second connection holes.

A hand-held power tool, such as an angular grinder, includes a housing having a main handle, and a support member for supporting a side handle in different positions relative thereto and pivotable relative to the housing about two support points, which may be on opposite side surfaces of the housing.
