  • 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.

  • Patent number: 10530536
    Abstract: The disclosure is related to an RF signal processing apparatus. The apparatus includes a processor and a buffer memory circuit. The apparatus includes a host interface for connecting with a host and an RF circuit for transmitting and receiving RF signals. The processor processes the RF signals to or from the RF circuit. The processor converts the received RF signals into data, or converts the data into the RF signals to be transmitted. The buffer memory circuit has a controller and two buffer memories. This memory architecture allows a system to assign a task to a first buffer memory and another task to a second buffer memory without restricting that the conventional buffer memory is limited to doing one task at a time. This memory architecture can solve inefficiency problems due to insufficient data transmission since the conventional buffer memory cannot be filled within a limited time period.
