Abstract: The present invention discloses a method for controlling wireless network devices, which includes the following steps: a control device with a wireless network function is utilized to scan several access-point (AP) mode wireless network devices. One of the AP mode wireless network devices is selected as a master AP according to the scanning result. The at least one AP mode wireless network device other than the selected one is set to a client mode. The at least one wireless network device set to the client mode builds a connection to the control device with a wireless network function through the master AP. The present invention also discloses a control device with a wireless network function.

Abstract: A system with storage device includes a storage device and an electrical device. The storage device includes a storage unit, at least one hotkey and a first hot plug interface. The at least one hotkey generates a control instruction corresponding to the at least one hotkey when operated. The control instruction is written to a block for storing instructions of the storage unit. The electrical device includes a second hot plug interface and a processing unit. The storage device builds connection with the electrical device through the first hot plug interface and the second hot plug interface when the first hot plug interface is electrically connected with the second hot plug interface. The processing unit makes the second hot plug interface obtain the control instruction from the block for storing instructions of the storage unit through the first hot plug interface. The processing unit executes the control instruction.

Abstract: An electrical device with zooming function includes an image-sensing module, a display unit and a processing unit. The processing unit is electrically connected to the image-sensing module and the display unit respectively. The image-sensing module senses an image. The processing unit includes an image display module, a selecting module and a zooming-control module. The image display module makes the display unit display the sensed image. The selecting module receives a selection signal for selecting a reference point from the image displayed on the display unit. The zooming-control module makes the image-sensing module sense another image, the reference point is in the center of which, by zooming.
