Abstract: An apparatus includes a predetermined function circuit board having a primary area for accepting an electronic module to be tested, a secondary area coupled electrically with the primary area, and one cooperation electronic module installed on the secondary area and coupled electrically to the electronic module to define a predetermined function circuit. A thermal insulation device is installed in the primary area and is formed with a thermal insulation chamber for accepting the electronic module and thermally insulating the electronic module from the cooperation electronic module. A thermal control chip is disposed to control a testing temperature of the insulation chamber TIC, thereby providing a testing environment.

Abstract: A download management system includes a server, a computer host and a storage device. The server stores an encrypted data, which is encrypted according to a certification signature. The computer host is communicatively connected to the server for executing a management program. The storage device is connected electrically to the computer host and includes the certification signature, wherein the download management execution program is capable of reading the certification signature from the storage device, downloading the encrypted data from the server, decrypings the encrypted data according to the certification signature to obtain a decrypted data, and storing the decrypted data in the storage device.

Abstract: A data secure system includes a computer host and a storage device having a certification signature. The computer host includes an encryption/decryption program, a data transceiver unit, an encryption module, and a decryption module. The data transceiver unit is communicatively connected to the storage device and an external device for receiving a raw data from the external device. The encryption module reads certification signature from the storage device via the encryption/decryption program, encrypts the raw data into an encryption data according to the certification signature, and stores the encryption data in the storage device. The decryption module reads the certification signature and the encryption data from the storage device via the encryption/decryption program and decrypts the encryption data according to the certification signature. Moreover, a method of storing and reading data is also provided.
