Abstract: A method is provided. The method includes determining a first bump map indicative of a first set of positions of bumps. The method includes determining, based upon the first bump map, a first plurality of bump densities associated with a plurality of regions of the first bump map. The method includes smoothing the first plurality of bump densities to determine a second plurality of bump densities associated with the plurality of regions of the first bump map. The method includes determining, based upon the second plurality of bump densities, a second bump map indicative of the first set of positions of the bumps and a set of sizes of the bumps.

Abstract: A semiconductor device includes a first contact layer, a second contact layer, an active layer, a photonic crystal layer, a passivation layer, a first electrode and a second electrode. The first contact layer has a first surface and a second surface opposite to each other. Microstructures are located on the second surface. The second contact layer is located below the first surface. The active layer is located between the first contact layer and the second contact layer. The photonic crystal layer is located between the active layer and the second contact layer. The passivation layer is located on the second contact layer. The first electrode is located on the passivation layer and is electrically connected the first surface of the first contact layer. The second electrode is located on the passivation layer and is electrically connected to the second contact layer.

Abstract: A workout device includes a base frame, a top cover and a gliding mechanism. The base frame includes a chassis and through holes formed in the chassis. The top cover includes dome structures aligned with the through holes, respectively, when the top cover is assembled to the base frame. The gliding mechanism consists of multi-directional rotating members accommodated in the dome structures and partially protruding from the through holes, respectively, when the top cover is assembled to the base frame. In response to a pressing force exerted onto the cover body, the dome structures are in contact with the multi-directional rotating members so as to cause friction therebetween, and the friction changes with the force exerted onto the cover body.

Abstract: A controlling circuit for a communication port having a ring indicator (RI) pin is provided. The controlling circuit includes a first selection circuit and a second selection circuit. The first selection circuit is controlled by a basic input/output system (BIOS) for determining whether an RI signal is transmitted to the RI pin. The second selection circuit is controlled by the BIOS for determining whether a first voltage or a second voltage is transmitted to the RI pin.

Abstract: An electronic testing apparatus is provided. The electronic testing apparatus includes a testing paper having a first reaction line and a second reaction line; a circuit board, having a light source, a first detector, a second detector equipped thereon, the light source being disposed between the first detector and the second detector; and a light shelter, defining a first chamber, a second chamber, and a third chamber, in which there is a first slit configured between the first chamber and the second chamber, and a second slit configured between the second chamber and the third chamber. The first chamber, the second chamber, and the third chamber respectively shelter the first detector, the light source, and the second detector. The first detector detects a reflected light of the light projected to the first window through the first slit by the light source, and the second detector detects a reflected light of the light projected to the second window through the second slit by the light source.

Abstract: A dumbbell includes a bar, a soft cushion wrapping around the bar, two end caps, and two weights as main components. The two end caps respectively are combined with and close on two ends of the bar. Between each end cap and a vertical circular disc is formed a support space for each weight to fit around thereon. Each weight has an elastic annular cloth bag wrapping iron sand, having flexibility to change its shape a bit by force to fit tightly around the support space. A user can replace the weights with other ones of different weight volume. If the dumbbell should fall down on the ground, it might not produce sound because of flexibility of the weights, not hurting a user or a person around, the ground surface or the weights, and thus very safe to use.

Abstract: A sport cap includes a body, eyelets respectively in a front and a rear portion, an eyelet in the top, drop-shaped air holes around the top eyelet, a protector respectively extending down from a right and a left side of the body, an opening formed just behind each protector, and a protective peripheral edge formed along a peripheral lower side of the body.
