Abstract:
A complex circuit board including a printed circuit board assembly (PCBA) and a flexible printed circuit (FPC) for providing driving signals for light sources is disclosed. The PCBA includes a supporting portion and a connecting portion. The light sources are disposed above the supporting portion. The connection portion contacts electrically with a contacting portion of the FPC. The contacting portion of the FPC has a fixing hole. The connecting portion of the PCBA has a fixing portion. Moreover, the FPC has two or more than two first bend portions on the contacting portion. The fixing portion of the PCBA is inserted into the fixing hole of the FPC to complete the complex circuit board without extra attachment units. Therefore, the assembly procedure is simplified to increase throughput and the cost is reduced.

In one embodiment of this invention, the first size is smaller than the second size, while in another embodiment, the first size is greater than the second size.
Abstract:
A centrifugal fan is described. The centrifugal fan is suitable for a portable electrical apparatus. A tongue shape is formed from a volute sidewall of a casing of the centrifugal fan and non-parallel to a rotational axis of blades. Therefore, when the blades rotate to generate a wake flow to blow on a surface of the volute sidewall at the tongue shape, noise generated by the centrifugal fan can be decreased.
Abstract:

The power amplifier units are connected in parallel with each other to receive a differential input signal. The power amplifier units perform a power amplifying so as to output a differential output signal. The bias unit is coupled to the power amplifier units and supplies a plurality of bias signals to the power amplifier units respectively. At least two of the power amplifier units are enable to operate in different class regions in according with the corresponding bias signals.
Abstract:
A mobile device and navigation device communication system utilizing near field communication to easily capture and transfer address data and simplify programming of the navigation device is disclosed. When a mobile device receives a text message a mobile navigation communication application determines if there is an address included in the text message and if found extracts the address and encodes the address. The user then places the mobile device in close proximity to the navigation device and the data exchange is performed via near field communication. After the data exchange is complete the navigation device decodes the data into the address and searches its database to find an address match. The navigation device then displays the address for the user to confirm. After confirmation the navigation device displays the route or driving directs from the user's current location to the destination address.
