A ventilator device for a freight container configured to prevent the ingress of water into the cargo tank interior. The ventilator device comprises a floatation-based valve configured to shuttle backwards and forwards in response to contact with water. The valve acts to open and close the air flow passageway through the device and is mounted over the air flow vents of the container. A manual override actuator may be provided to manually open and close the valves.

The invention provides a radio frequency identification (RFID) mobile phone payment method and an RFID mobile phone payment system utilizing the over the air technology (OTA) to recharge. The RFID mobile phone payment method comprises the steps that: an offline account is set on a mobile phone payment platform, and the offline account is recharged through a recharging fund resource; an RFID mobile phone starts the mobile phone balance monitoring program for inquiring the account balance; whether the account balance is lower than the set value or not is judged, if so, a recharging request is sent to the mobile phone payment platform at the operator side, and the recharging request comprises the recharging amount; the mobile phone payment platform judges whether the recharging request is legal or not, and if so, the recharging amount is deducted from the set offline account; an OTA recharging platform is notified of recharging the account on the RFID mobile phone, and the notifications comprise the recharging amount and the information of the recharged mobile phone; the OTA recharging platform returns the recharging response to the RFID mobile phone after recharging; and the RFID mobile phone changes the account balance according to the recharging response issued by the OTA recharging platform. The RFID mobile phone payment method and the RFID mobile phone payment system have the advantage that users can conduct a transaction through the self offline fund account of the RFID mobile phone.

The invention discloses an air and gas synchronous controller. The air and gas synchronous controller comprises a shell, an air inlet end, a push rod and an elastic piece, wherein the shell is hollow and is divided into an air inlet cavity and a movable cavity by a membrane, the air inlet end is located at one end of the shell, a gas pipeline is communicated with the air inlet cavity through the air inlet end, the push rod is located in the movable cavity, one end of the push rod is connected with the membrane, the other end of the push rod is connected with an opening and closing piece at an air outlet, and the elastic piece is located in the movable cavity and abuts against the membrane. Compared with an air and gas synchronous controller in the prior art, the air and gas synchronous controller has the advantages that the structure is simple, and cost is lower. Compared with other products in the market on the aspects of functions and effects, the air and gas synchronous controller has the advantages that the air outlet volume can be adjusted in real time, fuel gas can be fully burnt, and continuous manual control over the air outlet volume is not needed.
