The magnetic core assembly includes a first magnetic part, a second magnetic part and a third magnetic part. The base is arranged between the first magnetic part and the second magnetic part. The first magnetic part has a first post accommodated within the first receptacle. The at least one winding coil assembly is disposed on the base. The third magnetic part is optionally accommodated within the first receiving recess, so that an air gap between the third magnetic part and the first magnetic part/the second magnetic part is adjustable.
Abstract:
A chip-type antenna for receiving FM broadcasting signal includes a ceramic substrate, a ferrite layer formed on a top surface of the ceramic substrate, and a radiation structure. The ceramic substrate and the ferrite layer form an antenna substrate. The radiation structure is formed on the antenna substrate. The chip-type antenna for receiving FM broadcasting signal utilizes the high dielectric constant of the ceramic substrate and the electric characteristic of the ferrite layer to reduce the dimension of the antenna.

Abstract:
An over current protection method for a power supply includes steps as follows. Firstly, an output current value of the power supply is received. Secondly, whether the power supply has an over current status is determined in accordance with the received output current value. Thirdly, if the over current status occurs, the over current status is monitored to check whether the over current status continues for more than a setting period of time. If the over current status continues for more than the setting period of time, the power supply is disabled. On the other hand, if the over current status is eliminated with the setting period of time, a process flow returns to the first step of receiving an output current value of the power supply.
Abstract:
A frequency adjustable antenna apparatus and a manufacturing method thereof are disclosed. The antenna apparatus includes a plurality of antenna paths and the length of the antenna path is changed via the soldering pads. Therefore, the receiving frequency of the antenna can be changed. The frequency adjustable antenna apparatus includes a body, a first path, at least one second path and a printed circuit board. The first path is located on an upper surface of the body and extends to a lower surface. The second path is located on the lower surface. The printed circuit board includes at least one soldering pad. When the lower surface of the body is pasted on the printed circuit board, the first path is connected with the second path via the soldering pads. Thereby, the length of the first path is changed to adjust the frequency of the antenna apparatus.

A lens/frame combination for a pair of glasses includes a frame and at least one lens made of a material different from that of the frame. The frame includes at least one receiving portion having a coupling groove for coupling with the at least one lens. The at least one lens includes a peripheral edge that is at least partially and securely coupled with the coupling groove of the frame, forming a jointing area therebetween. The peripheral edge of the at least one lens is received in the coupling groove of the at least one receiving portion to a depth of 0.7 mm-5.0 mm, preferably 0.9 mm-5.0 mm.
Abstract:
A side-view optical diode package is mounted on a printed circuit board with at least a solder bump. The side-view optical diode package includes a silicon substrate, a holding space, a bonding surface and a positioning structure. The silicon substrate has a first surface and a second surface. The holding space has a top opening in the first surface and a bottom for holding an optical diode thereon. The bonding surface is disposed at a lateral side of the silicon substrate and bonded onto the printed circuit board. The positioning structure has at least a solder-receiving portion beside the bonding surface and corresponding to the solder bump. The solder bump is molten during a soldering process and received in the solder-receiving portion, thereby facilitating positioning the silicon substrate on the printed circuit board.
Abstract:
A broadband circularly polarization antenna device includes: a dielectric body, a patch, an antenna feed pin, and a grounding layer. The patch is disposed on a top surface of the dielectric body. The antenna feed pin is extended outward from a bottom surface of the dielectric body. One part of the grounding layer is coated on the bottom surface of the dielectric body, and the other part of the grounding layer is coated entirely around a lateral side of the dielectric body. Because the grounding layer is coated on the bottom surface and the lateral side of the dielectric body, the bandwidth of the antenna device is increased and interference from a PCB and other surrounding circuits to the antenna device is greatly reduced, thereby ensuring the antenna device performs well.

A chip package including a multilayer substrate, an adhesive core layer and a chip is provided. The multilayer substrate has a plurality of material layers. The adhesive core layer is disposed on the multilayer substrate. The chip is disposed in the adhesive core layer. The chip has an active surface exposed outside the adhesive core layer. The chip includes a plurality of bonding pads disposed on the active surface and a plurality of metal conductive bodies electrically connected to the bonding pads respectively.
Abstract:
A flexible antenna apparatus and a manufacturing method thereof are provided for wireless communication devices. The flexible antenna has a metal layer with an adhesive layer pasted onto the back surface of the metal layer, so that it can be directly pasted onto the housing of the wireless communication device. On another side of the metal layer, there is a transparent protective layer and the metal layer reserves a zone without the transparent protective layer for electrically coupling to the electrical substrate of the wireless communication device. The present flexible antenna apparatus reduces the developing time and cost of the device and the manufacturing process more convenient. The flexible antenna apparatus is suitable for all wireless communication devices and increases the flexibility of the manufacturing process by adding a holder having at least one plastic pin, or a pin.
