    • Method and apparatus for recording sweat gland activity which provides a pictorial representation thereof by physical contact of an iodide treated skin area with a dry sensitized substrate. In one preferred embodiment, the sensitized substrate comprises a sheet material which has been coated with an aqueous solution containing from 1 to 10 percent by weight of starch and from 2 to 10 percent by weight of a suitable oxidizing agent such as potassium persulfate. Alternately, the dry sensitized substrate comprises a starch-oxidizing agent mixture which has been impregnated into an absorbent base layer. With slight modification of the foregoing embodiment, the present invention also provides a method and apparatus for obtaining inkless fingerprints by forming a sensitized coating in situ on a substrate. For fingerprinting purposes, the sensitized coating is preferably formed from a quick drying starch-oxidizing agent solution including alcohol as a solvent. Accordingly, an aqueous iodide solution is applied to the skin area, and the treated skin area is subsequently contacted with the dry sensitized coating to produce the fingerprint.
    • 用于记录汗腺活性的方法和装置,其通过碘化处理的皮肤区域与干敏感基质的物理接触提供其图示。 在一个优选实施方案中,敏化基材包括已经用含有1-10重量%淀粉和2-10重量%合适氧化剂如过硫酸钾的水溶液涂覆的片材。 或者,干敏基材包括已经浸渍到吸收剂基层中的淀粉 - 氧化剂混合物。 通过对前述实施方案的微小修改,本发明还提供了通过在基材上原位形成敏化涂层来获得无油指纹的方法和装置。 为了指纹的目的,敏化涂层优选由包括醇作为溶剂的快干淀粉 - 氧化剂溶液形成。 因此,将碘化碘水溶液施加到皮肤区域,随后将处理过的皮肤区域与干敏涂层接触以产生指纹。

    • A compact fingerprinting system includes an applicator comprising a sealed packet (13) containing a porous pad (12) impregnated with a solution of water-soluble, color-forming, marking compound, such as iron chloride having a controlled, optimum water content. A print of a body part, such as a finger, is formed by opening the packet (60) and wiping the distal portion of a finger (76) on the pad (62), such as a folded towelette to form a non-visible, latent image pattern. The pattern is transferred to a card (40) which can contain an area (44) impregnated with developer for the marking compound. The developer reacts with the pattern to form a dark, distinct, permanent image (84). The card (40) and packet (13) can be enclosed in an envelope (64) to form a low profile, lightweight, mailable, self-administered fingerprinting system.
    • 一种紧凑的指纹系统包括一个包含一个密封的包装盒(13)的包装袋,该密封包装袋(13)包含一个浸渍有水溶性成色标记化合物(例如具有受控的最佳含水量的氯化铁)的溶液的多孔垫片(12)。 通过打开包装(60)并擦拭垫(62)上的手指(76)的远端部分(例如折叠的小毛巾)来形成身体部分(例如手指)的印刷品,以形成不可见的 ,潜像图案。 将图案转移到可以包含浸渍有用于标记化合物的显影剂的区域(44)的卡(40)。 开发人员与图案进行反应,形成一个黑暗,鲜明,永久的图像(84)。 卡(40)和分组(13)可以封装在信封(64)中,以形成一个薄型,重量轻,可用的自我管理的指纹系统。

    • Fingerprints images are formed by applying the distal portion 29 of a finger 32 to a porous pad 10 impregnated with a solution of marking compound. The finger portion may be prewetted or cleaned with cloth 30 impregnated with detergent solution. The finger 32 is then applied to a square 36 of a fingerprint card 38 impregnated with an aqueous solution of polyhydroxy developer such as 8-hydroxy-quinoline and propyl gallate containing a high molecular weight dibasic acid such as azelaic acid. A fingerprint image 40 immediately develops. Traces of the image can be removed with a cleaning solution impregnated cloth 42.
    • 指纹图像通过将指状物32的远侧部分29施加到浸渍有标记化合物溶液的多孔垫10而形成。 可以用浸渍有洗涤剂溶液的布30预先润湿或清洁手指部分。 然后将手指32施加到浸渍有多羟基显影剂的水溶液的指纹卡38的正方形36,所述多羟基显影剂例如8-羟基 - 喹啉和含有高分子量二元酸如壬二酸的没食子酸丙酯。 指纹图像40立即显现。 可以用清洁溶液浸渍布42去除图像痕迹。
