Abstract: Power conversion system includes a DC/DC conversion circuit, an energy tank, a switch, and a controller. DC/DC conversion circuit is configured to convert a first DC power into a second DC power and provide second DC power to a dynamic load. Energy tank is coupled to DC/DC conversion circuit. Switch is coupled between energy tank and DC/DC conversion circuit. Controller is coupled to energy tank and switch, and is configured to detect a first voltage of first DC power and a second voltage of second DC power to determine a change of dynamic load. When controller detects that first voltage is lower than a first preset voltage or detects that second voltage is lower than a second preset voltage, controller conducts switch so that a third DC power stored in energy tank is provided to DC/DC conversion circuit to compensate one of first DC power and second DC power.

Abstract: An online signing system and method, a computing apparatus, and a computer-readable recording medium are provided. An assigned task is generated by a task assignment apparatus to the computing apparatus. The computing apparatus generates a signing request based on the assigned task to be transmitted to a client apparatus. The client apparatus downloads an assignment file from a storage database based on the signing request to display the assignment file on a display. The client apparatus receives an input via an input unit to generate a signature object on the assignment file, and transmits the signature object to the computing apparatus. After receiving the signature object, the computing apparatus combines the signature object and the assignment file to obtain a signed file, and transmits the signed file to the storage database.

Abstract: A compensational control method includes the steps of: controlling a plurality of indoor air conditioning apparatuses to be in operation according to a target temperature; receiving continuously an operating parameter and an environmental datum from each of the indoor air conditioning apparatus; determining whether there is a specific indoor air conditioning apparatus that needs support; acquiring an adjacent indoor air conditioning apparatus which is influential for the specific indoor air conditioning apparatus according to an influence form which is previously built; establishing a supportive strategy according to a supportable operation capability of the adjacent indoor air conditioning apparatus; and adjusting the operating parameter of the adjacent indoor air conditioning apparatus according to the supportive strategy. Therefore, the adjacent indoor air conditioning apparatus is provided to improve an ambient temperature of an area where the specific indoor air conditioning apparatus is installed.
