摘要： An accelerometer without internal mechanical attachments. Three parallel cylindrical magnets are fixed within a housing. Each cylindrical magnet has a long axis extending through the housing and a cylindrical cross-section. The cylindrical cross-sections of the cylindrical magnets are organized to form a triangular formation. The magnetization of the cylindrical magnets is tangential to the triangular formation. A diamagnetic mass object levitates within the three cylindrical magnets by the magnetization of the cylindrical magnets at an equilibrium position near the center of the triangular formation and near a central axis of the three parallel cylindrical magnets when no external force is applied. Sensors detect the location of the diamagnetic mass object when the diamagnetic mass object is displaced from the equilibrium position near the center of the triangular formation and the three parallel cylindrical magnets by an external force to the housing.

摘要： In one of aspects, a mobile electronic device that is configured to determine transportation thereof comprises at least one controller that is configured to, while a predetermined vibration is being detected, determine that the transportation is a train when a predetermined change in magnetic field strength is detected within a predetermined period of time. On the other hand, the at least one controller is configured to determine that the transportation is an automobile when the predetermined change in the magnetic field strength is not detected within the predetermined period of time. The at least one controller is further configured to determine that, when predetermined information regarding rotation of the mobile electronic device is detected, the transportation is an automobile even when the predetermined change in the magnetic field strength has been detected within the predetermined period of time.
