摘要： The invention includes a method of providing magnetic stability of a memory cell. The memory cell is generally located proximate to a conductive line, and proximate to a write mechanism that can set a magnetic state of the memory cell. The method includes receiving a representation of a maximum magnetic field intensity available from the write mechanism. A desirable placement of the memory cell relative to the conductive line can be generated for providing stability of the memory cell, while still allowing the write mechanism to change the magnetic state of the memory cell.

摘要： The present invention is related to detecting location of a navigation device using sensor data analysis, where the sensor is coupled to the navigation device. A hierarchical algorithm is used for making a series of decisions regarding the location of the navigation device, with each decision corresponding to a class among a plurality of classes related to the possible motion modes and/or precise location of the device, including the location of the device with respect to a person's body. By accurately identifying the device location, the hierarchical algorithm facilitates in providing relevant contextual information, thereby enhancing situational awareness.
