  • Publication number: 20180208265
    Abstract: A joint structure of a composite bicycle frame includes a base layer and at least one reinforcing layer. The base layer is made of a first polymeric matrix material doped with a plurality of first fibers. The first fibers have random fiber orientation, and the base layer has a first thickness. The reinforcing layer is adhesively connected to the base layer. The reinforcing layer is made of a second polymeric matrix material doped with a plurality of second fibers. The second fibers have a single fiber orientation. The reinforcing layer has a second thickness which is smaller than the first thickness of the base layer.

  • Patent number: 9991876
    Abstract: A master-slave flip-flop includes a master latch, a slave latch, a first logic gate and a signal transition detector. The first logic gate is receiving a reference clock and a first control clock, and outputting a first trigger signal to control one of the master latch and the slave latch, which are connected with a logic circuit, to switch to an opaque state or a transparent state, wherein the other one of the master latch and the slave latch is switched to an opaque state or a transparent state according to the reference clock. The above-mentioned master-slave flip-flop can correct sampling when a timing error occurs.

  • Patent number: 9608603
    Abstract: A sampling circuit includes a first latch, a second latch and a signal transition detector. The first latch is disposed on an upstream side of a logic circuit. The second latch is disposed on a downstream side of the logic circuit. The first latch and the second latch respectively switch to opposite states of an opaque state or a transparent state according to trigger signals generated by a reference clock and a control clock. The signal transition detector is configured for detecting whether the signal outputted by the logic circuit is in error or not and outputting a corresponding control clock. The above-mentioned sampling circuit can delay switching the second latch to the opaque state and switching the first latch to the transparent state to correct sampling when a timing error occurs.

  • Publication number: 20150270591
    Abstract: A method and device for harvesting and storing solar energy is provided. The device converts solar energy to electrical energy via the photovoltaic effect. The device includes a pair of electrodes, at least one of which is transparent to allow solar energy to pass through. A medium is disposed between the electrodes which exhibits a combination of photovoltaic and ferroelectric properties. When solar energy passes through the transparent electrode and is received by the medium, electron-hole pairs establish a voltage potential between electrodes in the device via the photovoltaic effect. The voltage potential may be retained and the mobile charge may be stored in the absence of solar energy via the ferroelectric effect.
