Latest Patents
One of Liu's latest inventions is a small form-factor pluggable transceiver. This device is designed to be coupled to a cable connector and a network device. It features a first connection port, a conversion unit, a transceiver unit, and a second connection port. The conversion unit includes a bandwidth indication pin, while the transceiver unit has a detection pin. The transceiver operates in a normal state based on a first voltage level provided by the detection pin and switches to an abnormal state with a second voltage level. The bandwidth indication pin signals whether the source is a copper cable-type signal and indicates an invalid rate. The detection pin provides the first voltage level based on this invalid rate by being connected to a ground point.
Another significant invention by Liu is an underwater robotic device. This device comprises a housing unit, a control unit, and a propelling unit. The housing unit features a base seat and an upper cover that are liquid-tight. The control unit, located within the housing, includes a circuit module and a center-of-gravity transferring module. This module has a movable weight member and a transfer driving mechanism that adjusts the center of gravity, allowing the device to control its movement in water. The propelling unit is connected to the housing and electronically linked to the control unit, generating the necessary force to propel the device forward.
