摘要： The wireless automatic controlling device for the electric water pump is designed in a way that there won't be any water pressure drop in the apartment units on every floor, which is consistent with the height and the power of the electrical pump. This system is consisting of two parts, the first part which includes a transmitter and a high-pressure sensor is connected to the sensor by a water pipe or water hose, and the second part of the system, the receiver, which can adjust to the MGH433 frequency that comes from any transmitter using a learning micro switch, receives this frequency and, after recognizing the received signal correctness, activates the 12 V output. After the activation of the 12 V receiver, its output will be connected to the closed electrical contacts of the low-pressure sensor with a ratio of 1 to 5 psi.

摘要： A fire fighting vehicle includes a powertrain, an accessory drive, and a controller. The powertrain includes an engine, an energy storage device, and an electromechanical transmission (i) electrically coupled to the energy storage device and (ii) selectively mechanically coupled to the engine. The electromechanical transmission is configured to (a) selectively drive a front axle and/or a rear axle and (b) selectively generate energy for storage in the energy storage device as stored energy. The accessory drive is positioned to receive a mechanical input from the engine and the electromechanical transmission. The controller is configured to selectively operate the powertrain in (i) a standby mode by operating the electromechanical transmission using the stored energy to drive the accessory drive with the engine off and (ii) a rollout mode by operating the electromechanical transmission using the stored energy to drive the the front axle and/or the rear axle with the engine off.
