A product authentication system includes a carrier for receiving paper currency. The currency bears a unique serial number. The carrier is attached to a product the authenticity of which may need to be verified. The carrier can serve as a hang tag attached to various products, such as designer clothing, shoes, or watches. The carrier is preferably fully transparent to expose the currency embedded within it and to expose the unique serial number. A verification system allows a user, such as a consumer, to enter alphanumeric characters representing the serial number of the currency and includes a data base containing an inventory of serial numbers representing legitimate products to which carriers with unique articles of currency have been attached. The alphanumeric characters are compared with the serial numbers contained in the data base and an output is provided for indicating the authenticity of a product only when the entered alphanumeric characters correspond to a serial number stored in the data base. Data entry may be performed at a consumer station that includes a keyboard and may be a stand alone unit or may include communications for linking the consumer station to at least one remote authentication center that may service numerous consumer stations over any suitable communication link, as such as the Internet. The consumer station may be in the form of a kiosk or may be a portable hand-held device with Internet access. Preferably, the carrier further incorporates a security tag for providing both anti-theft and authentication features.

Authenticity validation system and method

This invention relates to a piston and a method of manufacturing the same. The piston includes a substantially cylindrical member having a first end and a second end. The cylindrical member includes an open cavity extending axially from the second end to adjacent the first end such that the second end has an inner annular surface defined by an inner diameter. The piston further includes a disk having a radially outer surface defined by an outer diameter fixedly secured to the second end of the cylindrical member. The outer diameter of the disk is substantially equal to the inner diameter of the inner annular surface of the second end of the cylindrical member. A circumferentially extending recessed area for receiving particles produced while fixedly securing the disk to the second end of the cylindrical member is provided on either the radially outer surface of the disk or the inner annular surface of the second end of the cylindrical member.

Piston and method of manufacturing the same

An improved method of manufacturing a piston is provided. The piston includes a substantially cylindrical member having a first end and a second end. The cylindrical member includes an open cavity extending axially from the second end to adjacent the first end such that the second end has an inner annular surface defined by an inner diameter. The piston further includes a disk having a radially outer surface defined by an outer diameter fixedly secured to the second end of the cylindrical member. The outer diameter of the disk is substantially equal to the inner diameter of the inner annular surface of the second end of the cylindrical member.
