Abstract: A hanging type earphone includes an earphone body and an ear hook. The earphone body has a speaking portion and a first connecting portion thereon. A pair of polygonal prisms is disposed at opposite ends of the first connecting portion. The ear hook is shaped to fit a shape of ears and pivotally mounted to the earphone body for hanging the earphone body on an ear. The ear hook has a second connecting portion shaped as a bridge with a pair of piers disposed there-beneath. The pair of piers each defines a polygonal hole. The second connecting portion rides on the first connecting portion with the polygonal prisms inserted into the respective polygonal holes. A wall of each polygonal hole is at least partially split so that the polygonal hole is enlargeable to enable the polygonal prism to pivot therein.

Abstract: A wireless network device with data storage is provided that utilizes a wireless connection to communicate with a LAN. The wireless network device with data storage includes a control unit, a memory element and a wireless communication module. The control unit includes a base-band processor, an RF interface, an external memory interface and a host device interface, wherein the base-band processor is adapted to process all data input/output through each interfaces. The RF interface connects the wireless communication module with the control unit, the external memory interface connects the memory element with the control unit, and the host device interface makes the control unit connect with an electronic device. The wireless communication module is able to either transmit or receive wireless signals from other electronic devices. The memory element is divided into two storage areas, one used for storage of the driver program for the control unit, the other for storage of user data.

Abstract: A method for triggering a power supply module switch of a cordless electric-apparatus which includes a metal inductive area and an electrostatic inductive element comprising the following steps: when a user body approaches the device to a predetermined distance which is less than the electrostatic induction distance, the electrostatic inductive element detects electrostatic charge from the user body so as to turn a switch within the electrostatic inductive element on; a power supply module supplies power for the cordless electric-apparatus when the switch is turned on; when the user body leaving away from the cordless electric-apparatus exceeds the electrostatic induction distance, the switch within the electrostatic inductive element turns off and when the switch turns off the power supply module supplies a part power for the cordless electric-apparatus.
