Patent ID: 6975476

Claim:
A mobile host device, comprising: a memory device, the memory device being configured to receive a shock event signal; a single tri-axial shock sensor coupled to the memory device and configured to generate the shock event signal, the single tri-axial shock sensor including: a magnet defining a first region that is magnetized in a first polarization direction and defining a second region that is magnetized in a second polarization direction; a fixed sensor assembly coupled to the first region of the magnet and magnetized in the first polarization direction; a movable sensor assembly coupled to the second region of the magnet and magnetized in the second polarization direction, the movable sensor assembly being configured to: remain out of contact with the fixed sensor assembly as long as the shock sensor does not undergo a shock event equal to or greater than a predetermined magnitude and to deflect in any of the x, y and z directions to contact the fixed sensor assembly and change the level of the shock event signal irrespective of a direction of the shock event when the shock sensor undergoes a shock event in any direction whose magnitude is equal to or greater than the predetermined magnitude and to remain in contact with the fixed sensor assembly.
