The invention relates to a process for bonding by molecular adhesion of two substrates to one another during which the surfaces of the substrates are placed in close contact and bonding occurs by propagation of a bonding front between the substrates. The pump comprises a pump body, an inlet valve within the pump body, an exhaust valve within the pump body and in fluid communication with the inlet valve, and a deflate valve within the pump body and in fluid communication with the inlet valve and the exhaust valve. The particle reinforced component may be formed by a process that includes providing reactive particles that have a reactive polymerization promoter chemically bonded or coated on the surface of the reactive particles and contacting the reactive particles with a resin solution that includes monomers of a polymer. A micro-controller is programmed so that it determines whether any of the fault status indications have been changed from being an inactive status to an active status. In some embodiments the delay circuit or a ring oscillator incorporating the delay circuit may be fabricated as an integrated circuit. The image security method includes photographing an image through a camera, storing the image, and storing Subscriber Identity Module information of the portable terminal in EXchangeable Image File information of the image.
