The present invention relates to an illumination module for a microscope apparatus, comprising a plurality of monochromatic sources and a control device, wherein the control device is configured to control states of the plurality of the monochromatic sources, and the control device includes a selecting and switching module which realizes a switch among the plurality of monochromatic sources in response to an operation of the user. The design of the illumination module makes the microscope apparatus compact in structure, highly reliable, convenient in use, and extremely enhancing the work efficiency of the user. The present invention also relates to a method for controlling the illumination module, and a microscope apparatus comprising the illumination module.

Illumination module for microscope apparatus, corresponding control method and microscope apparatus

A microscope, including an x motor, a y motor, and a z axis focusing driving mechanism that drive a stage to move; at least one knob operatively coupled to the x motor or y motor or the z axis focusing driving mechanism selectively via a controller; and at least one button coupled to the controller in communication. The controller is configured to disconnect a normal operative coupling between the knob and the z axis focusing driving mechanism and establish an operative coupling between the knob and the x motor or y motor when receiving a predetermined button signal, and restore the normal operative coupling between the knob and the z axis focusing driving mechanism and disconnect the operative coupling between the knob and the x motor or y motor when no longer receiving the predetermined button signal or when receiving a next button signal.

A power module and a power device having the power module are disclosed. The power device includes a main board. The power module is inserted in the main board and includes a PCB, a magnetic element, a primary winding circuit and at least one secondary winding circuit. The magnetic element is provided on the PCB and includes a core structure, a primary winding and at least one secondary winding. The core structure has a first side and a second side opposite to each other, and a third side and a fourth side opposite to each other. The primary winding circuit is provided on the PCB and positioned in the vicinity of the first or second side of the core structure. The secondary winding circuit is provided on the PCB and positioned in the vicinity of the third or fourth side of the core structure.

Power module and power device

An electronic apparatus includes a converting circuit and a first control circuit. The converting circuit converts an input voltage to an output voltage. The first control circuit compares a feedback signal representing the output voltage with a target voltage to generate an error voltage. When the electronic apparatus is on a starting-up status and the error voltage is not greater than a threshold voltage, the first control circuit outputs a first driving signal to drive the converting circuit according to the error voltage. When the electronic apparatus is on a starting-up status and the error voltage is greater than the threshold voltage, the first control circuit stops outputting the first driving signal. A frequency of the first driving signal is determined according to the error voltage.

Electronic apparatus and control method of electronic apparatus

A resonant conversion system is provided, in which a resonant converter receives an input voltage to generate an output voltage, and a buck converter provides the input voltage of the resonant converter, and controls the input voltage to perform an over-current protection process.
