  • Patent number: 10149202
    Abstract: Embodiments are provided for indicating response frame types according to response frame durations in a wireless network. The embodiments include defining a plurality of response frame types in accordance to different transmission durations. The different response frame types are assigned corresponding indication values. When transmitting a current frame to a receiver entity, a transmitter entity selects a response frame type from the defined response frame types, and indicates in the current frame the selected response frame type using the assigned indication value. When a third entity receives the current frame, the third entity waits for a time period about equal to a predefined inter-frame and backoff time before transmitting a new frame. Upon determining that the indication value in the current frame is for sending a response frame, the third entity also waits an additional time period about equal to the transmission duration of the indicated response frame type.

  • Publication number: 20180294500
    Abstract: A method is disclosed for improving the durability of membrane electrode assemblies in solid polymer electrolyte fuel cells by reducing the amount of halogen ion contaminants present. Silver carbonate is dissolved in an ionomer dispersion and incorporated into an appropriate component in the fuel cell where it reacts with halogen ion present to form silver halides. The component is then exposed to a suitable light source that decomposes the halide into halogen gas which is then removed prior to final assembly of the fuel cell.
