A bistable relay and a bistable actuator are provided. The bistable actuator includes a magnetic latching mechanism and an electromagnet. The magnetic latching mechanism includes a rotation shaft, a pillar-shaped permanent magnet, a columnar hollow magnetic conductor and two shells, and operates between a first and second stable states. The columnar hollow magnetic conductor surrounds the pillar-shaped permanent magnet wrapping the rotation shaft, and maintains a gap with the pillar-shaped permanent magnet. The electromagnet is connected to the columnar hollow magnetic conductor for driving the pillar-shaped permanent magnet to rotate, so as to switch the magnetic latching mechanism to the stable state. During a process that the magnetic latching mechanism is switched to the stable state, the rotation shaft rotates synchronously along with the magnetic latching mechanism to drive an impact system to move relative to a contact system, so as to contact or disconnect the contact points.

Data compression/decompression methods and data compressor/de-compressor are provided. The data compression method includes the steps of scaling an input signal to generate a scaled signal; transmitting the scaled signal to a differentiator and an assembler; differentiating the scaled signal and a prior signal to generate a differentiation signal detecting zero bits of the differentiation signal to generate a zero range control signal and a zero range control word; refining the differentiation signal according to the zero range control signal to generate a refined signal; and determining to combine the zero range control word with the scaled signal or combine the zero range control word with the refined signal according to the zero range control word to generate a compressed signal.

A trace capture device includes a processing system, a trace capture control unit and a bus unit. The processing system includes at least one function block arranged to generate first data, second data, and correlation information corresponding to the first data. The trace capture control unit is arranged to receive the first data and correlation information corresponding to the first data from the processing system, and generate third data according to the first data and the correlation information. The bus unit is coupled to the processing system, the trace capture control unit and a data link interface. The bus unit is arranged to use the data link interface to transmit information derived from the second data in a first mode, and reuse the first data link interface to transmit information derived from the third data in a second mode.

A bistable switching method and a latching relay using the same are provided. The latching relay includes a rotor shaft, a cylindrical permanent magnet, a first permeability material, a second permeability material, a coil, a hitting device and a contact unit. The method includes the following steps. While the coil is applied first direction currents, the rotor shaft rotates and to make the contact unit from the open state to the closed state or the contact unit keeps the closed state. After the first direction currents are turned off, the contact unit still remains in the closed state. Otherwise, while the coil is applied second direction currents, the rotor shaft rotates and to make the contact unit from the closed state to the open state or the contact unit keeps the open state. After the second direction currents are turned off, the contact unit still remains in the open state.
