Abstract: A hanging structure applicable to an unmanned aerial vehicle includes a hook-shaped body and at least one hook claw. The hook-shaped body has a bottom, at least one pivoting end, and an abutting portion. A hook opening is provided between the at least one pivoting end and the abutting portion and is opposite to the bottom. In addition, the at least one hook claw has a pivoting portion, and a first claw portion and a second claw portion that extend from the pivoting portion, respectively. The pivoting portion is pivoted to the at least one pivoting end. The second claw portion is heavier than the first claw portion. When the hanging structure is in a hanging state, a first end of the first claw portion abuts against the abutting portion, and the hook opening is closed. An unmanned aerial vehicle hanging system including the above hanging structure is further provided.

Abstract: An integrated circuit includes an inductor that includes a first set of conductors in at least a first metal layer, and a guard ring enclosing the inductor. The guard ring includes a first conductor extending in a first direction, a second conductor extending in a second direction, and a first set of staggered conductors coupled to a first end of the first conductor and a first end of the second conductor. The first set of staggered conductors includes a second set of conductors in a second metal layer, a third set of conductors in a third metal layer and a first set of vias coupling the second set of conductors with the third set of conductors. The third metal layer is above the second metal layer. All metal lines in the second metal layer that are part of the guard ring extend in the first direction.

Abstract: Provided is an inspection tool for a touch panel, including a substrate adapted to be placed on the touch panel and multiple protrusions disposed on the substrate in correspondence to multiple touch inspection points and arranged along an inspection trajectory. An inspection method for a touch panel is also provided.

Abstract: Presented herein are techniques to reduce error probability and eliminate the lingering signal that causes problems during audio signal data transmission. An electroacoustic transducer of a first electronic device receives a data encoded audio signal that includes modulated digital data therein. The data encoded audio signal is demodulated to produce a present input signal that includes a target frequency and a lingering effect of a previously received data encoded audio signal. Lingering cancellation is performed on the present input signal to produce a present output signal from which the lingering effect of the previously received data encoded audio signal has been removed.
