An image scaling system includes a window memory, a longitudinal scaler, a buffer and a latitudinal scaler. The window memory temporarily stores partial data of N image lines. The longitudinal scaler performs a longitudinal scaling operation on the partial data of the N image lines to thereby produce partial data of a longitudinal image line. The latitudinal scaler performs a latitudinal scaling operation on the partial data of the longitudinal image line to thereby produce scaling-part data of a latitudinal image line. The longitudinal scaler and the latitudinal scaler use a window average to perform an image shrinking operation and a bi-linear interpolation average to perform an image expanding operation.

A heat sink assembly ( ) comprises a heat sink ( ) and a clip ( ). The heat sink has a base ( ) and a plurality of fins ( ) extending therefrom. A central receiving groove ( ) is defined between two rows of fins. A pair of opposing ridges ( ) is formed on each pair of opposing fins which straddle the groove. The clip comprises a main body ( ) and opposite legs ( ) extending therefrom. The main body has three integrally connected frames ( ). Two outer frames are coplanar, and a plane of an intermediate frame is offset away from a plane of the outer frames at an acute angle. The frames are interferentially held in the groove between the ridges, fins and the base. The legs extend in different directions such that the clip is broadly Z-shaped when viewed from above, and broadly V-shaped when viewed from a side thereof.

Readily attachable heat sink assembly

A heat sink clip assembly includes clip ( ) and two handles ( ) attached to the clip for facilitating operation. The clip is integrally made of spring steel wire. The clip has a horizontal pressing section ( ) and two spring arms ( ) extending perpendicularly from opposite ends of the pressing section. The spring arms extend generally upwardly in different directions from the pressing section. A hook ( ) is formed at a free end of each spring arm. Each handle has a rectangular base plate ( ) and two fixing blocks ( ) formed at diagonally opposite corners of the base plate. The blocks extend toward each other along two orthogonal edges of the base plate. A groove ( ) is defined in an inner side surface of each block. The grooves are parallel to the base plate, and respectively accommodate part of the pressing section and part of one of the spring arms.

Heat sink clip assembly with handles

A clip ( ) for securing a heat sink ( ) to an electronic device ( ) mounted on a circuit board ( ) between two retention modules ( ) includes a central pressing portion ( ), a pair of spring portions ( ), a pair of legs ( ) for engaging with one retention module, a connection plate ( ) extending outwardly from a distal end of one leg, and a handle ( ) extending inwardly from a distal end of the connection plate. A pair of ribs ( ) is formed on the clip for reinforcing the clip. The handle comprises a strip ( ) engaging with a joint section of the clip between one spring portion and one leg, and a flange ( ) opposite to the strip and abutting one edge of the joint section. When the handle is downwardly pressed, the leg connected with the handle moves outwardly thereby disengaging the leg from the retention module.

Clip for heat sink

A fastener ( ) securing a heat sink ( ) and an electrical fan ( ) to a CPU ( ) includes a pressing frame ( ), a pair of activating members ( ) and a pair of locking members ( ). The fastener cooperates with a retention module ( ) to receive the heat sink and the fan therein. The activating members are pivotally attached to opposite lateral sides of the pressing frame. The locking members are pivotally attached to the activating members. When the activating members are upwardly and inwardly rotated, the locking members rise accordingly. Thus the locking members pressingly engage with the retention module, and the pressing frame firmly presses the fan. The heat sink is thereby firmly secured to the CPU with the fastener.
