摘要:
A lamp holder structure includes a base body, two electrode plates, a rotary shaft, a short-circuit part, and a cover. When multiple sets of lamp holder structures are used in serial connections, a shaft part of the rotary shaft is rotated by rotating a lamp-tube for the lamp holder structure. Conducting terminals of the lamp-tube are electrically contacted with the two electrode plates. Before rotating the lamp-tube, the short-circuit part is electrically contacted with the two electrode plates. After rotating the lamp-tube, the short-circuit part is electrically contacted with one of the two electrode plates. The electrical connection between the two electrode plates is achieved by the lamp-tube. When the lamp-tube is removed, the lamp-tube is rotated again, so that the short-circuit part is electrically contacted with the two electrode plates, and the two electrode plates are short-circuited. The power could be transmitted to the next lamp holder structure.

A line tensioning system for regulating tension on a line having a proximal end and a distal end, where the proximal end is operatively connected to a drum. The line tensioning system comprises a frame, a first and second sets of rollers, and first and second sets of displacement assemblies. The frame defines first and second side edges. Each first and second displacement assembly is arranged to displace at least one of the first and second rollers relative to the first and second side edges of the frame, respectively. The line is arranged such that the line contacts the first and second rollers. The first and second displacement assemblies displace the first and second rollers relative to the first and second edges based on a tension on the line.

A touch method and a touch system using the same are disclosed. The touch system comprises a display panel and an image sensing module. The touch method comprises the following steps: detecting and acquiring a coordinate position of a touch object entering a sensing region of the display panel; determining whether the touch object is moving or situated at a fixed point according to the coordinate position; sensing a first reflective luminance generated by the touch object at a point via the image sensing module; sensing a second reflective luminance generated by the touch object at the point via the image sensing module after a time period; comparing the first and the second reflective luminance; if the first reflective luminance is different from the second reflective luminance, then determining that the touch object is performing a fixed point rotation; executing a corresponding instruction according to the fixed point rotation.

摘要:
A rope comprising a plurality of yarns, where at least one of the plurality of yarns is a blended yarn comprising a plurality of first fibers and a plurality of second fibers. Aabrasion resistance properties of the second fibers are greater than abrasion resistance properties of the first fibers. A coefficient of friction of the second fibers is less than a coefficient of friction of the first fibers. The second fibers substantially define abrasion resistance and coefficient of friction characteristics of the at least one blended yarn. When the rope contacts a structural member, the first set of fibers of the at least one blended yarn substantially bear tension loads on the at least one blended yarn and at least a portion of the second fibers of the at least one blended yarn substantially lie between the set of first fibers and the structural member.

A blended yarn and method of making the same. The blended yarn is formed into a rope adapted to engage structural member and comprises a plurality of first fibers and a plurality of second fibers. The abrasion resistance properties of the second fibers are greater than abrasion resistance properties of the first fibers. A coefficient of friction of the second fibers is less than a coefficient of friction of the first fibers. The first fibers extend along the length of the blended yarn and the second fibers do not extend along the length of the blended yarn. A plurality of blended yarns are combined to form the rope such that, when the rope contacts the structural member, the second fibers of the blended yarn are primarily in contact with the structural member and the first set of fibers substantially bear tension loads on the rope.

The invention provides a glass fiber facing sheet for engineered surfaces such as cement boards which reduces the pitting associated with open mesh glass scrims. The glass fiber facing sheet comprises an open mesh glass scrim having a plurality of intersecting continuous multifilament yarns which are bonded at their crossover points to provide dimensional stability to the scrim. A melt blown polymer web is preferably joined to one face of the glass scrim and covers the mesh openings in the scrim. The opposed face of the scrim defines an exposed grid profile surface which is available for mechanical interaction between the scrim and the cementitious slurry used in cement boards. In cement boards, the glass fiber facing sheet of the present invention is preferably mechanically integrated into a surface portion of the cement core along the exposed grid profile of the scrim. A second facing sheet may also be mechanically integrated into an opposed surface portion of the cement core and contain a melt blown polymer web joined to one face. The present invention further includes a method of making the glass fiber facing sheet of the invention and a method of making a smooth cement board containing the glass fiber facing sheet of the invention.
