A power budget controller for an Ethernet device is disclosed. The Ethernet device is connected with another Ethernet device through a cable. The power budget controller includes a length estimation unit, a power selection unit and a link monitoring unit. The length estimation unit is utilized for generating a detection signal to the cable and for estimating length of the cable according to a refection waveform of the detection signal. The power selection unit is coupled to the length estimation unit, and utilized for adjusting a transmission power of the Ethernet device according to an estimation result of the cable length. The link monitoring unit is coupled to the power selection unit, and utilized for monitoring a link status of the Ethernet device to determine whether the transmission power is selected correctly.
摘要:
A winding mechanism mounts at a groove of a head rail of a blind and comprises a cord wrapped around a bottom stiffener strip and the head rail, a rope roller, a rope wound around the rope roller and coupled to the cord, a first roller coupled to the rope roller by gear, a second roller, and an S-shaped spring interconnected the first and second rollers, the spring adapted to exert a force to support the drapery material. In a downward pulling of the stiffener strip the rope roller rotates to release the rope and the cord with one worm section of the spring being further wound and the other worm section thereof being loosened for reaching a balance with the blind. An upward pulling of the same has an opposite effect. The drapery material is able to stay at any position in response to stopping the rope roller.
