Abstract: A server management system disposes two wave generators on a rack and disposes a wave sensor on a server, wherein each of the wave generators is capable of emitting an omni-directional wave and a directional wave. When the wave sensor senses the omni-directional wave and the directional wave at different time points, one of the server and a host device is capable of determining two angles of the wave sensor relative to the two wave generators according to time differences and then calculating a position of the server located in the rack according to the two angles.

Abstract: A burglarproof device and method are presented for preventing an electronic device from being used by an unauthorized user. The burglarproof device includes an anti-theft module and an authentication device. The anti-theft module and the authentication device can communicate with each other by wireless communication, in which the anti-theft module is mounted internally within the electronic device and the authentication device is mounted externally to the electronic device. The anti-theft module can send an authentication activation signal to the authentication device upon the activation of a power switch of the electronic device. The authentication device can be actuated upon the reception of the authentication activation signal and send an encoded signal generated by encoding an authentication code retained in the authentication device to the anti-theft module. The anti-theft module can decode the encoded signal and check whether the decoded signal is a legitimate authentication code.
