Abstract
A method and a system for scanning frequencies in an electronic device include storing one or more frequencies, performing a scan based on the stored frequencies for a predetermined time interval, and establishing a connection based on the scan. The system includes an acquisition database for scanning frequencies in an electronic device, a timer module for setting a predetermined time interval as the scanning interval, and a frequency identification module for identifying one or more frequencies of a normal scan and a limited scan.
Claims6
1-31. (canceled)
An electric contact structure comprising:
- a flexible circuit board including a polyimide layer having upper and lower surfaces and copper foils arranged on said upper and lower surfaces of to sandwich said polyimide layer;
- an electric contact having a surface, at least a portion of said surface being adapted to contact a mating object, said portion being plated with a noble metal;
- said contact extending from a top surface of one of said copper foils, said contact secured to said top surface by solidification of a metal paste layer or conductive paste layer coated on said copper foil, said noble metal layer extending over at least a part adapted to contact a mating object;
- wherein said contact is a metal ball with a spherical shape adapted to contact the mating object;
- and
- wherein said circuit board has a substantially U-shaped slit is formed almost all around said contact so as to give flexibility of the contact when contacting with the mating object.
The electric contact structure of claim 31, further comprising an elastomer arranged under said circuit board.
The electric contact structure of claim 31, wherein said metal ball is made of an alloy.
The electric contact structure of claim 31, wherein said polyimide layer is provided with through holes so that said copper foils contact one another.
