Abstract: In a method of detecting firmware using a first electronic device, the first electronic device comprises a first baseboard management controller (BMC). The first electronic device receives a first message of requiring the first electronic device from a host computer, to detect whether firmware of a second BMC of a second electronic device runs in a normal state. The electronic device sends a second message of requiring the second BMC to obtain whether firmware of the second BMC runs in the normal state. Once the second BMC dose not response to the second message in a first predetermined time period, the electronic device recovers the firmware of the second BMC using firmware of the first BMC.

Abstract: In a method of testing stability of updating firmware of a baseboard management controller (BMC) of an electronic device, the electronic device comprises a first storage device that stores original firmware data of the BMC, and a second storage device that stores update data of the firmware. The electronic device tests the stability by repeatedly erasing the original firmware data and writing the update data into the first storage device. Once the electronic device updates the firmware of the BMC for a predetermined number of times, the process is ended.

Abstract: An electronic apparatus controlled by a self-checking system. The self-checking system constantly detects and stores, in a limited storage, a number of state characteristics of the electronic apparatus and constantly writes over and thus deletes previous data. An operating system in the electronic apparatus transmits a reset instruction before the expiry of predetermined time intervals. The self-checking system starts a timing process when the operating system is started and resets the timing process when a reset instruction is received from the operating system. If a reset instruction is not received before the expiry of a predetermined time interval, the self-checking system stores the instantaneous state characteristic of the electronic apparatus to make preparation for a failure analysis by the user.

Abstract: A pre-adhesive syrup copolymer composition comprising an acid functional acrylate solute copolymer, a monomer solvent mixture, and a polyaziridine crosslinking agent is disclosed.

Abstract: The invention provides an electromagnetic shielding adhesive tape, comprising: a resin film layer; and an electromagnetic interference shielding layer with a sandwiched structure, which is laminated with the resin film layer and comprises: a first adhesive layer bonded to one side of the resin film layer; a second adhesive layer; and a conductive metal layer provided between the first adhesive layer and the second adhesive layer.

Abstract: A centrifugal fan includes a fan frame (20), and a stator (30) and a rotor (40) received in the fan frame. The fan frame includes a bottom base (22), an opposite top cover (21) and a side wall (23) interconnecting the bottom base and the top cover. A first air inlet (24a) is defined in the top cover and a second air inlet (24b) is defined in the bottom base. The rotor includes a hub (41) and a plurality of blades (42) extending from an outer periphery of the hub. An air flow channel (48) is formed between an outer periphery of the blades and the side wall of the fan frame. A cylindrical wall (26, 26a) is formed around one of the first air inlet and the second air inlet to guide airflow from the first and second air inlets into the air flow channel and block the airflow in the air flow channel from flowing back towards the first and second air inlets.

Abstract: Described is a pre-adhesive, curable composition comprising an acid-functional (meth)acrylate copolymer and a novel (meth)acryloyl-aziridine crosslinking agent, which when crosslinked provides a pressure-sensitive adhesive composition.

Abstract: A cooling fan includes a frame (100) and an impeller (200) having a plurality of blades (240) disposed in the frame (100). The frame (100) has a cap (120) with an air inlet (122), a base (140) and a sidewall (160) extending from a periphery of the base (140) with an air outlet (180) defined therein. The cap (120) is mounted on the sidewall (160) with a chamber formed between the cap (120), the base (140) and the sidewall (160). A curved tongue portion (190) is formed on the sidewall (160) in vicinity of the air outlet (180). A protrusion (124) is formed on the cap (120) in vicinity of the curved tongue portion (190) and protrudes into the air inlet (122).
