  • Patent number: 11447050
    Abstract: A manufacturing method for a car safety seat includes the following steps: providing a mold and disposing a main body of the car safety seat into the mold, and injecting a foam material into a cavity of the mold and foaming the foam material so as to form a flexible layer integrated with the main body. A pressure in the cavity is between 1.5 bar and 5.0 bar. The manufacturing method disposes the main body into the mold and directly forms a flexible layer on the main body, so that the flexible layer ensures safety and comfort of the car safety seat while saves the necessity to dispose a seat pad or a cushion and fixing structures on the main body, and thereby reduces the cost and the work-hour of assembly, and the overall weight of the car safety seat can be reduced by omitting the fixing structures.

  • Patent number: 11444842
    Abstract: A network switch and a network switch system thereof are provided. The network switch includes a plurality of connection ports and a processing circuit. When any of the connection ports receives a first abnormal message packet and one of the connection ports is in a disabled state, the processing circuit sets the connection port in the disabled state to switch to an enabled state, and the processing circuit does not forward the first abnormal message packet in the single loop network. When one of the connection ports is abnormal and each of the connection ports forming the single loop network is in the enabled state, the processing circuit sets the abnormal connection port to switch to the disabled state, and transmits a second abnormal message packet to other network switches in the single loop network through another connection port that is not abnormal.

  • Publication number: 20200022462
    Abstract: A harness system with a buckle restraining function includes an upper buckle, an upper strap and a restraining assembly. The upper strap slidably passes through the upper buckle, and the upper strap includes a shoulder portion and a waist portion divided by the upper buckle. The restraining assembly utilizes an anti-sliding structure having a higher coefficient of friction to engage with the upper strap and further utilizes a stopping component to abut against the upper buckle. Therefore, the present invention can effectively restrain a sliding movement of the upper buckle relative to the upper strap and toward the shoulder portion by engagement of the anti-sliding structure and the upper strap and abutment of the stopping component and the upper buckle, which prevents an excessive decrease of a length of the shoulder portion of the upper strap and prevents a potential risk of injury of the passenger's upper body.
