A driving apparatus for driving at least one first light emitting diode unit and a second light emitting diode unit includes a data transmitting unit and a driving unit. The data transmitting unit is used for receiving and storing driving data. The driving data includes first data corresponding to a first driving signal and second data corresponding to a second driving signal. The driving unit divides the first driving signal into a plurality of first sub-driving signals and the second driving signal into a plurality of second sub-driving signals, and then alternately outputs the first sub-driving signals and the second sub-driving signals to alternately drive the first light emitting diode unit and the second light emitting diode unit.

Disclosed is an electronic seal for sealing a door. The door is equipped with a latch. The electronic seal includes a plug and a socket. The plug can be inserted in the socket through the latch. Thus, the door is sealed by the electronic seal. The door cannot be opened without breaking the electric seal. The electronic seal records any event of breakage.

An optical fiber connector assembly includes a first connector and a second connector. The first connector includes two pairs of first convex lenses projecting from a front mating face thereof and a pair of cone-shaped positioning posts at sides of the pairs of convex lenses respectively. The second connector includes two pairs of second convex lenses projecting from a second front mating face thereof to couple with the first convex lenses and a pair of positioning holes to be inserted with the positioning posts of the first connector. Each of the positioning holes includes a retention section and a guiding section in front of the retention section, and the retention sections is same to the positioning posts while the guiding sections is larger than the position posts in dimension.

An IC socket, adapted for electrically connecting an IC package and a printed circuit board, includes a base, a socket body received in the base, a plurality of contacts received in the socket body, and an actuating mechanism moveably assembled on the base. The socket body includes a first insulative housing and a second insulative housing located under the first insulative housing. The actuating mechanism can actuate the first insulative housing and a second insulative housing to move in a horizontal direction relative to each other and drive the contact to stretch in a vertical direction.

A burn-in socket for electrical connecting with package having solder balls, includes a base and a number of contacts received in the base. Each contact has a spring section movable in the base, a contact section extending upwardly from the spring section and a retention section extending downwardly from the spring section. The contact section includes three tips at a top end thereof for contacting with the solder balls of the package thereby supporting the solder balls.

A burn-in socket for testing an integral circuit package includes a base defining a cavity, an adapter received in the cavity of the base, an alignment plate secured to the adapter, and a cover movable mounted to the base. The alignment plate is detachable assembled to the adapter so as to the burn-in socket can apply to different IC package when the alignment plate is replaced with another.
摘要:
An IC socket includes a socket body with a plurality of contacts disposed therein, a lid pivotably coupled to the socket body, a pushing member connected to the lid, and a heat sink fixed to said pushing member and being movable in a height direction relative to the lid. Because of being fixed to the pushing member, the heat sink can move with the pushing member and keep pressing on an IC chip in the case, for example, the changing of the thickness or position of the IC chip.

An electrical connector includes a frame (2) is a substantially rectangular configuration and including a front portion and rear portion (22), a cover (3) moveably disposed on the frame and including a supporting portion (31) with a plurality of holes (311) defined therein, a lever (4) having a shaft portion (42) disposed on the rear portion of the frame to drive the cover to move from a first position to a second position, a base (1) disposed within the frame and under the cover and an elastic mechanism received between the base and the cover. The cover further defines a groove (33) which is used for receiving the elastic mechanism when the cover is in the second position.
摘要:
A CD storage sleeve for a compact disc mainly has at two lateral sides or at least at one side in a horizontal diametric direction of the compact disc a stop point pointing inwardly in order that the width of the CD storage sleeve at the area where the points are is nearly the diameter of the compact disc to thereby prevent the compact disc placed in from dropping but not to impede placing in of the compact disc; thereby a CD storage sleeve able to prevent the compact disc from dropping by clamping of a plurality of points is formed.

A decoding circuit is adapted for decoding an input signal. The input signal includes at least a break and the time length of the break is a preset time. The decoding circuit includes a decoding unit and a detecting unit. The detecting unit detects whether the voltage level of the input signal is kept at a specific logic level for more than the preset time. If the input signal is kept at the specific logic level for more than the preset time, the detecting circuit, according to the voltage level of the specific logic level, outputs the input signal or the inverted input signal to the decoding unit so as to perform a decoding process.
