  • Patent number: 9027259
    Abstract: Hydrating an object bearing a latent fingerprint and then selectively drying the object leaving the fingerprint hydrated. The hydrated fingerprint is then coated with cyanoacrylate ester, preferably in a heat accelerated cyanoacrylate ester vacuum chamber. Hydrating is preferably accomplished by chilling the object below a dew point and then exposing the object to humidified air to condense a thin uniform layer of water over the object and latent fingerprint. Drying is preferably done with a vacuum. After drying reaches the preferred state, the CE is heated and coats the condensation-hydrated latent fingerprint. Preferably, the method is implemented in an automated system using one computer-controlled chamber for chilling, condensing, vacuum drying, and CE coating the latent fingerprint. The operator simply puts the object in the chamber, initiates the process by computer, and is prompted by the computer to remove the recovered latent print. Prints unrecoverable by prior art means are recovered.

  • Patent number: 8877282
    Abstract: The apparatus and method or process of the present invention includes ID or fingerprinting kits to help brand a company's logo into a fingerprint. For many decades, companies have looked for unique ways to introduce their brand or logo into the marketplace. Companies have also helped law enforcement protect children by providing ID kits for distribution in communities. This apparatus and method or process looks to bring these two areas together by branding the company's logo into a fingerprint. The ID or fingerprint card must have a clear chemical coating then the non-visible brand or logo must also be printed on the card. This brand or logo may or may not include color. By applying a fingerprint activation solution to the chemically treated ID card, a fingerprint and logo or image will appear in the fingerprint.

  • Publication number: 20130305987
    Abstract: Methods and apparatus for the recovery, visualization and enhancement of latent fingerprints using Low Pressure Dye Vapor Deposition (LPDVD) are described. The LPDVD methods of the present invention provide for fine control over the deposition of a precursor in combination with a fluorescent dye, combination of dyes or a premixed dry solid compound of the precursor and dyestuffs, to make the latent fingerprints visible. The LPDVD process makes use of a heated carrier gas to dilute and carry the vapors into a vacuum chamber where they condense onto the exposed surfaces of the article being developed. The LPDVD process can be used to develop latent fingerprints on a wide variety of substrates, including metal, plastic, glass and thermal paper and has been shown to perform as well or better than conventional fingerprint development techniques on these surfaces.

  • Patent number: 6261809
    Abstract: The invention relates to a method for marking solid, liquid or gaseous substances, whereby the substance to be marked is provided with at least one synthetically produced nucleic acid sequence. Said nucleic acid sequence contains a first sequence section constructed with the 5′ terminal end, a second sequence comprised of at least two bases and connected to said nucleic acid sequence, and a third sequence section constructed with the 3′ terminal end and connected to the said nucleic acid sequence. In order to simplify the identification of the marking, the invention provides that a first primer group is used with a first primer section corresponding to the first sequence section and a second primer group is used with a third primer section corresponding to the third sequence section.

  • Patent number: 6186688
    Abstract: A Magnetic, latent fingerprint development brush featuring a non-rigid, removable, disposable cover/body, to be used when developing latent fingerprints on contaminated surfaces. The cover can be removed and cleaned or disposed of and exchanged with a new cover. The non-rigid design allows operation without tension springs. The tip is less abrasive against surfaces being printed, since it has no sharp rigid edges. This lessens the chance of distortion of the latent print. The design is simple. A magnetic rod is attached to a handle, which is inserted into a flexible removable cover/body. A light grip holds the cover against the handle during use.
