Patents by Inventor ZIH-MIN YANG

ZIH-MIN YANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11938366
    Abstract: A free weight training protection device includes a rack, two transmission modules, a control module and a barbell. The rack includes hanger structures which are configured to be laterally symmetrical to each other. The two transmission modules are configured to be laterally symmetrical to each other. Each transmission module includes a motor, sprockets, chains, pulleys and ropes. When a controller executes a fitness program, the controller operates the motor, so that the rope maintains a basic tension which is a very small tension and will not affect the hand feel of heavy training. If the barbell has an abnormal position or displacement, the controller will start a protection program to prevent the barbell from falling and move the barbell upward, so as to provide protections to users.

  • Patent number: 9864390
    Abstract: A power supply system and a power supply method thereof are disclosed. The power supply system includes a master power supply device and a slave power supply device. When a master power detection module detects that a current value of a master power signal generated from a master power supply module increases to a first loading proportion, a master micro-controlling module will notices a slave micro-controlling module via a controlling pin to enable a slave power supply module to generate a slave power signal. When a slave power detection module detects that a current value of the slave power signal decreases to a second loading proportion, the slave micro-control module will control the slave power supply module to stop generating the power signal.

  • Patent number: 9846464
    Abstract: The instant disclosure provides a power supply system and control method thereof. The power supply system comprises at least two power supplies electrically coupled in parallel. The control unit of the power supply generates a wake-up signal or a sleep signal according to the loading status. A second communication port of each power supply is coupled to a first communication port of the next stage power supply to establish cascading communications architecture. The first communication port receives a wake-up signal from the second communication port of the previous stage power supply and outputs a sleep signal to the second communication port of the previous stage power supply. The second communication port receives the sleep signal from the first communication port of the next stage power supply and outputs the wake-up signal to the first communication port of the next stage power supply.
