    摘要: A method for reducing a number of input terminals of an APC circuit is provided, where the APC circuit is arranged to control an optical pickup unit (OPU) within an optical storage device. The method includes: utilizing at least one switching module to ground one of a first and a second input terminals of the APC circuit at a time; and utilizing the switching module to electrically connect an APC front end within the APC circuit to a non-grounded input terminal of the first and the second input terminals, in order to receive a detection signal of a photo diode of the OPU through the non-grounded input terminal at the time. An associated APC circuit is also provided.

    摘要: A protective cover assembly is mounted within a portable electronic device. The portable electronic device defines a through hole. The protective cover assembly includes a resisting portion including a first positioning portion and a second positioning portion, a shielding cover and an elastic member offering an elastic force to make the resisting portion abut against the shielding cover. When the shielding cover resisting the first positioning portion, the shielding cover shields the through hole. When the shielding cover resisting the second positioning portion, the shielding cover exposes the through hole.

    摘要: Synthesizing a message sequence chart (MSC) from a communicating finite-state machine (CFSM), by transforming the CFSM to a Petri net model, generating a labeled finite digraph with each path representing a linearization of an occurrence net segment of the Petri net, decomposing the diagraph into segments, and mapping where each segment to a compositional MSC.
