  • Publication number: 20230323732
    Abstract: A safety cord tilter, in which two cords of the cord tilter for controlling opening or closing of the blind slats are exposed outside the headrail by a length set within a safety length range. The rear ends of the two cords are respectively connected with a first pull rod and a second pull rod for pulling the cords. When the first and second pull rods are used to control opening or closing of the blind slats, the first pull rod or the second pull rod reaches the blind rail at the top end, whereby the allowable exposed lengths of the pulled-out cords will not exceed the safety range so as to shorten the exposed length of the cords. This prevents a child from playing with the cords and twisting the cords around the neck and achieves safety effect.

  • Publication number: 20230224963
    Abstract: Various techniques pertaining to a special dual clear-to-send (CTS) mode for improvement in collision avoidance in wireless communications are described. A first station (STA) transmits a request-to-send (RTS) and, in response, receives a first CTS from a second STA. The first STA waits to receive a second CTS from the second STA before transmitting data to the second STA responsive to the first CTS being of a first type and the second CTS being of a second type different from the first type. The first STA then transmits the data to the second STA upon passage of a waiting period.
