Warning System Against Server/PC Stealers (03-Sep-2008)

Warning System Against Ｓｅｒｖｅｒ／PC Stealers

Disclosed is a warning system against stealers of server or personal computers.

The U-Shaped Level incorporated in PC/Server senses the fluctuation of the inner fluid surface position, caused by the

impacts given to PC/Server.

(Refer to Figures 1, Figure 2, Figure 3)

The Sensor-Process-Section assigns the Sensor-Signal-Numbers to each sensed signal.

(Refer to Figures 3, Figure 4)

The calculation logic uses the Sensor-Signal-Numbers to calculate and show the impcat severity to users.

(Refer to Figures 5)

Users respond to the logic with the acceptability of the impact severity, using pre-determined password or biometric

authentication.

(Refer to Figures 5)

If users supply no response, this warning system escalates the massages from warning into alarm with big sound against

stealers.

As the logic keeps the warning/alarm status in Non-Volatile-Memory of the Warning-Memory-Section (Figure 4), unless

users respond with due authenticity,
every time the power is ON, the logic continues to issue warning/alarm messages against stealers.

(Refer to Figure 4 / Figures 5)

Thus this system offers users
the flexibility in adjusting the severity level
the enhancement of the warning/alarm message function
the release from the physical connection/fixture of PC/Server

The U-Shaped Level is sealed to prevent leakage of inner fluid.

The volume of inner fluid is that of the bottom part of "C".

The volume of inner fluid (part "C") is larger than the remaining volume (the added total of parts "A" and "B"). The inner fluid does not exceed the X-Y line, when set horizontally even.

The bottom part sensors (s12/s13 in this case) sense the fluid, when set horizontally even.

The sensors of parts "A" and "B" (excluding s12/s13) do not sense the fluid, when set horizontally even.

The Sensor-Positions are marked with red.

The Sensor-Positions are numbered in ascending order from A to B (s1, s2, …, sN-1, SN).

The function of sensor is to sense the exi...
