Abstract: An integrated current sensing apparatus includes a magnetic-field sensing element, a power supply circuit, an offset adjustment circuit, a gain adjustment circuit and a regulating unit. The magnetic-field sensing element is configured for sensing magnetic field, and correspondingly generating a sensing voltage. The power supply circuit is electrically coupled to the magnetic-field sensing element, for generating a constant current to the magnetic-field sensing element to control the sensing voltage. The offset adjustment circuit is electrically coupled to the magnetic-field sensing element, for adjusting an offset of the sensing voltage. The gain adjustment circuit is electrically coupled to the offset adjustment circuit, for amplifying the sensing voltage to a rated output voltage. The regulating unit is electrically coupled to the power supply circuit, the offset adjustment circuit and the gain adjustment circuit, for controlling the constant current, the offset and a gain value.

Abstract: A quickly detached cooling fan mounting bracket for a computer, by which a cooling fan can be quickly removed away from a computer chassis without detaching any other peripheral devices, whereby a large enough computer inner space is exposed in order to facilitate rapid replacement of electrical components. The cooling fan mounting bracket includes a cooling fan receptive mount; a cooling fan; a connecting member, which allows the cooling fan receptive mount to be movably installed on the computer chassis; and a orienting member, which secures the cooling fan receptive mount and the cooling fan onto the computer chassis, and prevents the cooling fan from vibration during the normal operation. Compared with the conventional art, the present invention is easier to remove the cooling fan away from the chassis, thereby, facilitates rapid replacement or maintenance of the computer components.

Abstract: A computer system with a fixing module for riser card thereof is provided. By allowing the bottom side of the supporting pillar and the bottom parts of the two opposite sides of the supporting pillar engaging with each other, the riser card is supported by stress from all directions around it. Therefore, enough supporting strength is efficiently provided within a limited space and the riser card is prevented from being bended and having deformation because of the heavy weight.

Abstract: A fastening assembly for riser cards equipped with memory modules includes holders and latches. Each of the holders has bars and pillars to form a solid framework and couple to a mother board. The edges of the riser cards are held by holding grooves on the pillars to enable the riser cards sliding therein and insert towards riser sockets on the mother board. Meanwhile, the latches slip to latch the holding grooves to limit the movement of the riser cards. Thus, the fastening assembly improves the fixing strength of the riser cards and prevents from moving off while impacted, vibrated or crashed.

Abstract: A cooling system for a computer transfers heat away from a power supply and/or a central processing unit (CPU) in the computer. In an embodiment, heat is drawn away from the CPU to a heat sink by way of a heat pipe and a base member. In another, the heat sink is installed parallel to a power supply unit within the computer, and a fan is installed between the power supply and the heat sink.
