Abstract: A method for multiplexing control signals for disk drives includes developing parallel control signals and developing serial control signals. At least one of the parallel control signals and the serial control signals are coupled to at least one of a parallel hard disk drive and a serial hard disk drive by a common control bus.

Abstract: A heat sink clip assembly (1) for attaching a heat sink (5) on a CPU (7) includes a retention frame (10), and a pair of clips (20) pivotally attached to two sides of the retention frame. Each clip includes a main body (21), and a handle (41) pivotally attached to the main body. The main body includes a cross beam (23), and two locking arms (31) respectively depending from opposite ends of the cross beam. Each locking arm defines a locking hole (33) at a distal end. The handle has a cam portion (47) at one end thereof. The clips are pivoted outwardly to make way for the heat sink to seat on the CPU. Then the clips are pivoted upwardly, so that the cross beam is suspended above the heat sink. The handle is pivoted downwardly so that the cam portion presses the heat sink to the CPU.

Abstract: A heat dissipation assembly includes a heat sink (10), a fan (70), and a mounting device for attaching the fan to the heat sink. The mounting device includes four clips (30), and four shafts (50) pivotably connecting the clips to the heat sink. Each clip includes a main body (31), a top pressing portion (39), and a bottom mounting portion (43). A tab (45) is upwardly formed from a center of the mounting portion. Two parallel connecting portions (33) extend outwardly from two side edges of the main body respectively. The tabs of the mounting portions of the clips abut against the fan in corresponding through holes (72) thereof. The pressing portions of the clips press an upper face of the fan at corresponding through holes thereof. Thus te fan is securely mounted on the heat sink between the pressing portion and the mounting portion of each of the clips.

Abstract: A heat dissipating assembly includes a CPU (35) mounted on a motherboard (30), a fan (20), two clips (60), a heat sink (10), two fasteners (50), a back plate (40) and two posts (70). The heat sink includes a base (12) and a plurality of fins (14). Two ears (16) are formed at respective opposite sides of the base. The clips mount the fan to the heat sink. The back plate is placed under the motherboard, and the posts are sequentially extended through the back plate, the motherboard and the ears of the heat sink. The fasteners are retained on the ears of the heat sink around the respective posts. The fasteners are rotated, causing the posts to resiliently press the fasteners on the ears, and resiliently press the back plate on the motherboard. Thus the heat sink is securely attached to the CPU on the motherboard.

Abstract: A serial communications architecture for communicating between hosts and data store devices. The Storage Link architecture is specially adapted to support communications between multiple hosts and storage devices via a switching network, such as a storage area network. The Storage Link architecture specifies various communications techniques that can be combined to reduce the overall cost and increase the overall performance of communications. The Storage Link architecture may provide packet ordering based on packet type, dynamic segmentation of packets, asymmetric packet ordering, packet nesting, variable-sized packet headers, and use of out-of-band symbols to transmit control information as described below in more detail. The Storage Link architecture may also specify encoding techniques to optimize transitions and to ensure DC-balance.

Abstract: A fan holder (10) for attaching a fan (30) to a heat sink (40) includes a base (11) defining an opening (18) therethrough, two pairs of hooks (14), two pairs of posts (16) around the opening, a pair of positioning blocks (22), and two pairs of slots (15) defined in the base. The hooks depend from the base, and engage in grooves (46) defined through fins (42) of the heat sink. The posts extend upwardly from the base, and are received in corresponding holes (32) of the fan. Each post has a resilient engaging portion (24) and a notch (25), which allow the engaging portion to elastically compress and firmly attach the fan on the fan holder. The positioning blocks are formed under the base, on opposite sides of the opening. The slots are adjacent the hooks, and allow easy disassembly of the fan holder from the heat sink.

Abstract: A fan holder (10) for attaching a fan (30) to a heat sink (40) includes a base (11) defining an opening (18) therethrough, two pairs of hooks (14), two pairs of posts (16) around the opening, a pair of positioning blocks (22), and two pairs of slots (15) defined in the base. The hooks depend from the base, and engage in grooves (46) defined through fins (42) of the heat sink.

Abstract: A clip (10) for securing a heat sink (30) to an electronic device (40) includes a base (12), a pair of handles (16) and a pressing portion (18). The handles extend outwardly from opposite ends of the base. The base defines a slot (14) for receiving a catch (62) of a retention module (60). The slot includes first and second portion (142, 146) and a neck portion (144) therebetween. Upper limits of all three portions are colinear. The first portion has a vertical width greater than that of the second portion. A triangular protrusion (13) at the neck portion renders the vertical width of he neck portion less than that of both the first and second portions. The pressing portion extends inwardly from a top edge of the base. A pair of resilient tabs (242) depends from the pressing portion, for abutting a groove (36) of the heat sink. The catch is initially received in the first portion of the slot, and then moved over the triangular protrusion to the second portion.

Abstract: A fan holder (10) for attaching a fan (30) to a heat sink (40) includes a base (11) defining a vent (24) for allowing air flow, two pairs of legs (16, 18), two pairs of posts (14) around the vent and a pair of positioning blocks (22). The legs depend from the base, and each leg has a hook (166, 186) for engaging with the heat sink. A pair of slots (20) is defined in the base on opposite sides of each leg. A pair of handles (188) extends upwardly from one pair of legs, for facilitating operation of the holder. The posts extend upwardly from the base, for being received in corresponding holes (32) of the fan. Each post has a resilient tab (142), for resiliently and firmly attaching the fan on the holder. The positioning blocks are formed under the base, on opposite sides of the vent.

Abstract: A heat sink clip (4) includes a fastener (42) and a handle (44). The fastener includes a body (46) and first and second arms (54, 56) extending downward from opposite ends of the body. The first and second arms each define an aperture (58) for engaging with a corresponding tab (2) formed on an electronic device retention module (10). A pressing portion (64) is stamped adjacent a horizontal portion (48) of the body. The pressing portion is engagingly received in a slot (26) defined in a heat sink (20), and presses the heat sink against an electronic device (80) positioned in a socket connector adjacent the retention module. The handle has an operation section (72) and a joint section (74) extending downward from the operation section. The joint section forms a pair of vertical hems (76) at respective opposite sides thereof which extend toward each other to define a space (78). The space interferentially receives protrusions (62) formed on the second arm, whereby the handle is attached to the fastener.

Abstract: A clip includes a body (10) having a spring portion (12) and a leg (14) formed on a first end of the spring portion for engaging with a first side of a heat generating device, such as a central processing unit module. A fastener (20) has a spring plate (24) connected to a second end of the spring portion of the body and is engageable with an opposite second side of the heat generating device for securing a heat sink to the heat generating device. A pair of connecting tabs (26) extends from the fastener above the body for pivotally retaining an actuating member (30) therebetween. The actuating member forms cams (34) engaging the spring portion of the body whereby, when the actuating member is manually operated, the camming engagement between the actuating member and the spring portion drives the fastener to engage the second side of the heat generating device.
