Abstract: A clock signal detector is provided. The device comprises a plurality of signal delayers and a plurality of flip-flops for comparing the offset range of the clock signal between two different groups, and transmitting the resulted signal to a phase compensator, which is used to send a regulating clock signal to a clock generator. Therefore, the offset ranges of the clock signals from two different groups will be within the range of the system requirement, such that it can optimize the system operation.

Abstract: The present solar energy collector includes a substrate and a plurality of plates assembled on the substrate in a roof manner, wherein the plates include a plurality of protrusions capable of collecting a penetrating solar ray on a solar cell positioned at a predetermined region on the substrate. The solar energy collector may include two trapezoid plates and two triangular plates assembled on the substrate in an inclined manner to form a hip-roof. The solar energy collector may include four trapezoid plates positioned on the substrate in an inclined manner and one rectangular plate positioned on the trapezoid plates to form a mansard roof. The solar energy collector may include six first rectangular plates positioned on the substrate in a hexagonal manner, six second rectangular plates positioned on the first rectangular plates, and a hexagonal plate positioned on the second rectangular plates.

Abstract: A voltage monitoring circuit is capable of being integrated into a chip and monitoring the voltage quality. It mainly uses a first waveshaper to receive a voltage signal of a voltage source to be measured, process it to a logic signal, and output to a first logic level transformer. A first digital signal is transformed by the processing and can be recorded by a register such that a managing system can read content of the register through a bus to further determine whether the voltage source has a situation of voltage surge. Similarly, an inverter can be concatenated between a second waveshaper and a second logic level transformer to monitor whether the voltage source has undercurrent pulse. This way, an object of monitoring voltage quality in the chip with a combination of simple analog circuit can be achieved.

Abstract: A controlling method of logic operations is used to control a plurality of logics inside a chip, which is in a power peak state. The controlling method comprises the following steps of: providing a control signal to the chip, controlling at least one of the logics based on the control signal at a first timing, and controlling at least another one of the logics based on the control signal at a second timing. The control signal is intent to substantially control actions of the logics synchronously. Moreover, a mainboard and an electronic component, utilizing the controlling method of logic operations, are provided.
