An actuator of the present invention includes a set of generally planar assemblies comprising cross-hinges that are disposed between a set of extended arms and a rigid mounting base. The hinges of the present invention flex to about a pivot axis to replace the pivot and bearing assembly of prior art actuators. In an exemplary embodiment the hinges are used in conjunction with a voice-coil motor (âVCMâ).

A multiple disk drive storage system includes a latch assembly for positively latching a head positioning actuator arm when the head is positioned on a load/unload mechanism at the outer perimeter of the disks. Latching and unlatching cycles of the latch assembly are effected by interaction of the actuator arm motion and a latch arm retention magnet structure. In the latch position, the actuator arm is mechanically captured by a hook shaped latch head at one end of the movable latch arm, so that, even in a power off condition the actuator arm is positively latched by the combination of the actuator arm motion limitations, the latch head shape, the latch arm motion limitations and a bias spring urging the hooked latch head into a permanent, static latch with the actuator arm. The opposite end of the latch arm is provided with a magnetic mass which is attracted and held by the retention magnet. This magnet when the activated when the actuator arm is driven from a latching position toward a pre-reset position preparatory to releasing or unlatching the actuator arm.

A battery pack apparatus is disclosed that reduces the possibility of thermal runaway by improving the transfer of heat from the battery body and apparatus to the coolant by increasing the surface area of contact between the two. Principles of shape charge are used to drive debris, splinters and other particles towards the ground in an automobile in the event of an explosion, thereby reducing the possibility of harm to the driver, occupants and automobile. Fire retardant cartridges are suitably embedded to deter fire and incidental harm to person and automobile.
