Abstract: An earthquake detection system is disclosed. The earthquake detection system includes a main sensor, a first backup sensor, a second backup sensor and a third backup sensor. The main sensor is disposed on a free field. The first backup sensor is disposed on a structure. The second backup sensor is disposed below a ground surface at a depth of at least 20 meters. The third backup sensor is disposed at a remote end relative to the main sensor, and outputs a remote signal through a network so as to avoid misjudging the occurrence of earthquakes because of unnatural factors, and prevent the vibration caused by human activities from interfering with the detector. The earthquake detection system achieves the effect of verification through a plurality of sensors installed in different positions. Only when all the sensors confirm that there is an earthquake, an earthquake warning will be issued to the protected place.

Abstract: Examples herein relate to locking devices. In one example, a locking device comprises a metal sheet, the metal sheet comprising an elongated flexible arm established on a same plane as the metal sheet. The arm comprises an attached proximate end, a detached distal end, an elongated slot, the slot defining two opposite elongated edges and a locking bridge comprising an inclined surface. The locking bridge connects the two opposite edges by the detached distal end and the inclined surface of the locking bridge is adapted to retain a protrusion of the memory module.

Abstract: A locking mechanism involves a movable member and a fixed member. The fixed member has single-locking and double-locking features, as does the movable member. The single-locking features can be engaged and disengaged by movement of the movable member orthogonal to an axis. The double-locking features can be engaged by motion of the movable member along the axis orthogonal while the single-locking features are engaged.

Abstract: A filter member is movable between a first position and a second position when passage of air through the filter member is obstructed.
