Abstract: An integrated circuit for programming an electrical fuse includes a first programming device coupled to the electrical fuse for selectively providing the same with a first programming current, and a second programming device coupled to the electrical fuse for selectively providing the same with a second programming current. A detection module is coupled to the electrical fuse for generating an output indicating a resistance level of the electrical fuse, wherein the resistance level has three or more predetermined states, which are provided by selectively programming the electrical fuse with the first or second programming current.

Abstract: A system for generating a pulse signal in response to a clock signal includes a latch module for generating a latched output in response to a leading edge of the clock signal. A delay module is coupled to the latch module for delaying the latched output. A first logic device having a first input terminal coupled to the latch module and a second input terminal is coupled to the delay module for generating the pulse signal, which has a pulse width determined by a delay time of the latched output passing through the delay module. The pulse signal is coupled to the latch module for resetting the latch module when the pulse signal is not asserted.

Abstract: A sensing circuit is disclosed for sensing a programming state of an electrical fuse, comprising. An electrical fuse is coupled to a supply voltage. A first transistor is serially coupled between the electrical fuse and a complementary supply voltage. An inverter sense amplifier is coupled to a node between the electrical fuse and the first transistor for outputting a logic signal whose value is determined based on a comparison between a resistance of the electrical fuse and a predetermined reference resistance. A bias circuit applies a bias independent of variation of the first voltage to a gate of the first transistor, such that the predetermined reference resistance is substantially insensitive to the variation of the first voltage.

Abstract: A method for providing service for users to determine assembly match information of components is proposed. The method makes use of computer programs of a communication equipment and cooperation of a database and tag information on the components to provide inquiry judgement and match decision of components for users, thereby accomplishing realtime match inquiry of components and also avoiding erroneous manual assembly. The method not only can provide related specification information of components, but also can provide suggestion for component schemes. If the assembly match information changes, update information of the remote database can be transmitted via the communication equipment to a read/write device to update assembly match information in tags on components.

Abstract: A self-lubricating device for supplying lubricant onto a threaded guide rod, includes a movable member disposed above the threaded guide rod, and has lower threads meshed with the threaded guide rod, and a lubricant supplier secured on the movable member, and has a nozzle extending into the movable member for supply of lubricant onto the threaded guide rod. The movable member is movable axially on the threaded guide rod in such a manner to rotate the latter upon actuated.

Abstract: A pulse generator is disclosed which comprises a clock buffer coupled to a data latch coupled to a delay unit; a logic device coupled to the delay unit and the data latch, the logic device adapted to logically combine signals generated from the delay unit and the data latch and to generate a signal pulse; and a signal reset unit coupled to the data latch. A method of generating a pulse is also disclosed, comprising generating a signal state by sensing a rising edge of an external clock; latching the signal state for generating a latched signal state; delaying the latched signal state for generating a delayed signal state; and logically combining the latched signal state and the delayed signal state for generating a signal pulse.
