Abstract: A digital double sampling method, a related complementary metal oxide semiconductor (CMOS) image sensor, and a digital camera comprising the CMOS image sensor are disclosed. The method includes generating first digital data corresponding to an initial voltage level apparent in a pixel in response to a reset signal, inverting the first digital data, outputting a detection voltage corresponding to image data received from outside of the CMOS image sensor, and counting in synchronization with a clock signal, starting from an initial value equal to the inverted first digital data, and for an amount of time responsive to a voltage level of the detection voltage.

Abstract: A bicycle hub is provided for use with tangential bicycle spokes having a straight section and a bent end with an enlarged head such that straight section extends at an angle of about 95° relative to the bent end. The bicycle hub basically has a hub axle and a hub body. The hub axle has a center axis extending between a first end and a second end. The hub body has an interior passageway with the hub axle being rotatably supported therein. The hub body also has a set of first spoke openings circumferentially arranged around the hub body. Each of the first spoke openings having an insertion portion with a large width that permits the enlarged head of a tangential spoke to pass therethrough and a retaining portion with a width that is smaller than the width of the insertion portion to retain the enlarged head of the tangential spoke therein.
