In some implementations, a mobile device can be configured to monitor environmental, system and user events associated with the mobile device andor a peer device. The preferred route avoids a particular maneuver or particular maneuvers identified by a user. The forkpocket assembly includes at least one forkpocket protection plate. When the portable computer is disconnected from the docking station, a user is prompted for the disconnection password. In a semiconductor memory device including a memory transistor portion and a select transistor portion, at least the select transistor portion is formed of a fin-shaped single-crystal semiconductor thin film. A second movable element placed in operable proximity to said first Halbach array includes a second Halbach array permanent magnet array.
