Abstract: An active start judgment circuit is electrically connected to an AC/DC transforming power supply which has at least one standby power unit to transform AC to DC in regular conditions and a main power unit to transform the AC to the DC in an ON condition for operation of an electronic equipment. The start judgment circuit bridges the standby power unit and the main power unit, and generates a reference potential based on a voltage output from the standby power unit, and gets a power signal from the standby power unit to be compared with the reference potential to output a start signal to the main power unit to transform the AC to the DC. Thus the standby power unit can actively drive the main power unit to supply DC power to activate the electronic equipment.

Abstract: The present invention discloses a heat-dissipation structure for electronic devices, which comprises: a housing having an accommodation space accommodating at least one heat-generating element; a heat conductor arranged in the accommodation space and contacting the heat-generating element; and an electric fan arranged outside the housing. The housing has an opening corresponding to the heat conductor, and the heat conductor extends through the opening and projects from the housing. The electric fan drives an air current to flow through the part of the heat conductor extending through the opening to promote heat-dissipation efficiency.

Abstract: A damping structure for electronic devices has a holding rack mounted onto a chassis to hold an electronic device. The holding rack has two ends extended towards the chassis to form respectively a step portion and a first coupling section extended from the step portion. The holding rack has two other ends extended sideward to form second coupling sections to form a holding space for the electronic device. There are damping assemblies interposed between the holding rack and the chassis, and between the holding rack and the electronic device. The damping assemblies are independent and can provide elastic damping forces.
