Abstract: The present disclosure discloses a sound detection method.

Abstract: The present application relates to a safety prevention and control system and control method of a power battery pack for an electric vehicle. The safety prevention and control system of a power battery pack includes a signal acquisition device, a main controller, and a step-by-step prevention and control execution device. The main controller includes a fault diagnosis device, a cell thermal runaway determination device and a battery pack thermal runaway propagation determination device, which are respectively electrically connected to the step-by-step prevention and control execution device to send different control instructions to the step-by-step prevention and control execution device. The step-by-step prevention and control execution device can execute prevention and control actions of different levels according to the different control instructions sent by the fault diagnosis device, the cell thermal runaway determination device and the battery pack thermal runaway propagation determination device.

Abstract: An apparatus for treating a fuel is disclosed. The apparatus comprises a channel for fuel to be treated, a photocatalyst situated within the channel so as to be in contact with the fuel passing therethrough, electromagnetic radiation source means for irradiating the catalyst and magnetic field source means for providing a magnetic field to which the fuel is exposed.

Abstract: A novel heat pipe and a cooling system that employs the heat pipe are disclosed. The heat pipe has a configuration in the form of a nail that includes a flattened upper section and an elongated lower, section. The heat pipe may be in the form of nail shape or a continuous bar that includes a flattened upper section and an elongated section. The heat pipe may be employed together with a thermoelectric cooling module and a heat sink to provide a cooling device. The cooling device may be employed with a container to provide a cooling system.
