Abstract: Methods, systems and apparatus are provided to apply a magnetic pre-conditioning to magnetic tunneling junction (MTJ) sensors and other micro-magnetic devices after fabrication but before testing, trimming or other subsequent processing. The fabricated sensor device is passed through a magnetic field that has a known direction and orientation relative to the device so that the device is placed into a known state prior to final testing and trimming. Various embodiments allow the field to be applied in situ by a permanent magnet or electromagnet as the devices are being processed by a conventional device handler or similar processing system.

Abstract: An incoming telephone call is received at a private branch exchange. The telephone call is directed to a telephone extension of the private branch exchange. A call routing preference associated with the extension is determined and the telephone call is routed based on the call routing preference. If the call routing preference is set to a first preference, telephone call is routed to a telephone associated with the extension. If the call routing preference is set to a second preference, the telephone call is routed to a computing device associated with the extension.
