Abstract: An ultra thin package for an electric acoustic sensor chip of a micro electro mechanical system is provided. A substrate has a first substrate surface and a second substrate surface opposite to the first substrate surface. At least one conductor bump is formed on the second substrate surface. An electric acoustic sensor chip having a first chip surface and a second chip surface opposite to the first chip surface is provided. The first chip surface is electrically connected to the conductor bump. The conductor bump is positioned between the second substrate surface and the first chip surface to create a space. The conductor bump is used for transferring a signal from the sensor chip to the substrate. An acoustic opening passing through the substrate is formed.

Abstract: An auxiliary instantaneous heating and magnetization apparatus for the fuel system of a vehicle comprises an instantaneous heating apparatus and a magnetized combustion-aid apparatus. The instantaneous heating apparatus comprising an electric heating device, an automatic isothermal controller, a temperature fuse, a switch, an indicating light, and an electric source connected in series. The electric heating device is mounted to the fuel pipe at a location near the inlet of a carburetor or a fuel injection system. The magnetized combustion-aid apparatus comprises elongated permanent magnets covered by a housing being substantially C-shaped, in section, and is clamped on the fuel pipe at a location near the inlet of the fuel filter or corresponding to the electric heating device.
