  • Publication number: 20060109071
    Abstract: A magnetic component, like an amorphous metal ribbon component, is disposed within an aperture of a layer of circuit board substrate, like FR4 or a flexible substrate. That layer is then laminated between a top and bottom layer to form a circuit substrate with a magnetic component integrally formed therein. Conductive traces are disposed on the top layer and bottom layer. These conductive traces are coupled together about the magnetic component with conductive vias. The top traces, bottom traces and conductive vias form a “winding” about the magnetic component. The resultant assembly is a single, multi-layered circuit substrate with a magnetic circuit element integrally formed therein. The magnetic circuit component is suitable for use as, amongst other things, an inductor, a transformer, or a contactless charging primary or secondary coil.

  • Publication number: 20050288858
    Abstract: A portable electronic device, like a cellular telephone for example, includes software for executing a method for presenting directional indicator information to a user on a display. The device receives geographical information about its location, orientation information of its alignment and geographical information about a landmark of interest. The device then calculates a destination angle relative to the orientation information. The device then presents directional information, for example an arrow, to a user. In one exemplary application, Muslims are able to select Mecca as the landmark of interest. The device then uses information about its own location, the orientation of the device and the location of Mecca to present an arrow on the display indicating the proper direction for the Muslim to align themselves for prayer in accordance with the teachings of Islam.
