Abstract: A fast charging device for mobile electronic device is disclosed. Particularly, an input-end filtering unit contained in the fast charging device is designed to comprise two first input capacitors, one second input capacitor, and one switch element. By such design, in case of a rated voltage of an input AC power being smaller than 110 Vac, the switch element is controlled to complete a switch-ON operation, so as to make the input-end filtering unit execute a signal filtering process by simultaneously using two first input capacitors and one second input capacitor. Moreover, in case of the rated voltage of the input AC power being in a range between 110 Vac and 264 Vac, the switch element is controlled to complete a switch-OFF operation, so as to make the input-end filtering unit execute the signal filtering process by merely using two first input capacitors.

Abstract: A database query optimization computer-implemented method, medium, and system are disclosed. In one computer-implemented method, a data query request sent by a client device is received and parsed. An execution plan for executing the data query request is determined based on a parsing result. If the execution plan is a nested loop anti-join, whether there is a possibility that a to-be-queried field in a to-be-queried data table indicated by the data query request contains a NULL value is determined. If there is a possibility that the to-be-queried field contains a NULL value, a filter condition is generated and the execution plan is optimized based on the filter condition.

Abstract: A terahertz spectrum test device and system includes a femtosecond fiber laser configured to generate a pump light and a probe light. The pump light excites a terahertz transmitter to generate terahertz waves which are transmitted to a sample suspension device to irradiate a suspended to-be-tested sample, and the probe light is directly transmitted to a terahertz detector. The terahertz detector receives the terahertz waves transmitted from the sample suspension device, and then transmits the terahertz waves and the probe light together to a signal processing circuit to obtain a corresponding terahertz time-domain spectrum. By adoption of the terahertz spectrum test device and system, the to-be-tested sample need not be fixed with a clamp or other instruments, so that terahertz waves will not irradiate to the instrument used for fixing the to-be-tested sample during a terahertz spectrum test, which may otherwise affect the test result.

Abstract: The invention relates to a terahertz full polarization state detection spectrometer, which comprises a terahertz wave generator, a polarizer, a polarization splitter, a horizontal terahertz detector and a vertical terahertz detector. The terahertz wave generator generates a terahertz wave and the polarizer optimizes the terahertz wave for purity. The sample to be detected modulates the terahertz wave after purity optimization to obtain the terahertz modulated wave. The terahertz modulated wave is decomposed by the polarization splitter into a horizontal terahertz wave and a vertical terahertz wave whose polarization states are perpendicular to each other. The two terahertz waves are detected by two corresponding terahertz detectors respectively. According to the detected result, the characteristic of the sample is analyzed.

Abstract: A delay circuit is disclosed. The delay circuit is coupled to a relay switch that is contained in a power conversion device. When an electronic device having the power conversion device is operated in a sleep mode, the delay circuit applies a time delaying process to a power signal that is transmitted to the relay switch, such that a rising time of each of switch-on pulses contained by the power signal is delayed for a specific time. The specific time is set to be longer than a pulse width of each of power-on pulses contained by a power switching signal of the power conversion device. As such, when the electronic device is operated in the sleep mode, switching actions of the relay switch is properly controlled, thereby making the power conversion device not produce noise. Moreover, the service life of the relay unit is also extended.
