Abstract: A clock and data recovery (CDR) circuit includes an edge detector, an edge selector, and a phase selector. The edge detector is arranged to detect edges of serial input data and to provide an edge detection result. The serial input data is oversampled utilizing multiple clock phases. The edge selector for selecting one of the multiple clock phases for a recovered clock is arranged to provide an edge selection result, to receive the last edge selection result as a first input, and to receive the edge detection result as a second input. The phase selector is arranged to provide the recovered clock and recovered data.

Abstract: A plunger (22), used in a standard mold, has a movable piston (23) and spring (24) that reduce the cull space when piston (23) is pressed downward into the cull mold compound.

Abstract: An electric power cord with double-output terminal, comprising a casing formed of two symmetrical shells connected by bolts and retaining holes thereof, said symmetrical shells each having two arch-shaped vertical side walls symmetrically curving outwards at two opposite locations with a power input port therebetween and fastened with a first cable for connecting to a socket power and a straight vertical side wall at a right angle relative to said two arch-shaped vertical side walls and defined therewith two output ports fastened with a second cable and a third cable respectively for connecting said socket power to two separate electric appliances.
