Apparatus and method of determining conditions of bank notes

An apparatus and method for providing an indication of a type and/or a condition of a note passing through the apparatus includes a note transport (12) which moves the note past transversely spaced spot sensing assemblies (18). Each spot sensing assembly includes four emitters (32). Each of the emitters produces radiation at different wavelengths. The spot sensing assemblies include a reflectance detector (20) and a transmission detector (22) which are disposed on opposed sides of the passing note. The emitters direct radiation onto test spots (34) on the passing note. Radiation reflected from and transmitted through the test spots is detected by the respective reflector and transmission detectors. A control circuit (24) produces sensed values that correspond to the detected radiation. A data store in operative connection with the control circuit comprises memories (138) that include stored data representative of transition and reflectance values for know note types. The control circuit calculates a level of correlation between the stored values and the sensed values. By comparing the correlated values to threshold values, the control circuit is operative to determine the type of note and other conditions such as if a note is worn, soiled, or a doubles note.

Method and apparatus for drug product tracking using encoded optical identification elements

A method and apparatus for drug product tracking (or other pharmaceutical, health care or cosmetics products, and/or the packages or containers they are supplied with) using diffraction grating-based encoded optical identification elements 8 includes an optical substrate 10 having at least one diffraction grating 12 disposed therein. The grating 12 has one or more colocated pitches Λ which represent a unique identification digital code that is detected when illuminated by incident light 24. The incident light 24 may be directed transversely from the side of the substrate 10 (or from an end) with a narrow band (single wavelength) or multiple wavelength source, and the code is represented by a spatial distribution of light or a wavelength spectrum, respectively, or a combination thereof. The encoded element 8 may be used to label any desired item, such as drugs or medicines, or other pharmaceutical or health care products or cosmetics. The label may be used for many different purposes, such as for sorting, tracking, identification, verification, authentication, anti-theft/anti-counterfeit, security/anti-terrorism, or for other purposes. In a manufacturing environment, the elements 8 may be used to track inventory for production information or sales of goods/products. Such labeling provides product identification at the pill or liquid medicine level, which provides traceability of these products to their manufacturer, thereby reducing counterfeit products in the marketplace. Also, the elements 8 may be incorporated into a film, liquid, coating or adhesive tape at attached to the product package.

Currency handling system having multiple output receptacles

A method and apparatus for handling bill jams within a currency processing device is provided. The device includes a transport mechanism adapted to transport bills along a transport path, one at a time, from the input receptacle past an evaluation unit into a plurality of output receptacles. At least one of the output receptacles includes a holding area and a storage area. A plurality of bill passage sensors are sequentially disposed along the transport path that are adapted to detect the passage of a bill as each bill is transported past each sensor. An encoder is adapted to produce an encoder count for each incremental movement of the transport mechanism. A controller counts the total number of bills transported into each of the holding areas and the total number of bills moved from a holding area to a corresponding storage area after a predetermined number of bills have been transported into the holding area. The controller tracks the movement of each of the bills along the transport path into each of the holding areas with the plurality of bill passage sensors. The presence of a bill jam is detected when a bill is not transported past one of the plurality of bill passage sensors within a requisite number of encoder counts. The operation of the transport mechanism is suspended upon detection of a bill jam. The bills from each of the holding areas are moved to the corresponding storage areas upon suspension of the operation of the transport mechanism. Remaining bills are then flushed from the transport path after moving the bills from each of the holding areas to the corresponding storage areas upon suspension of the operation of the transport mechanism.

Self-authentication of value documents using digital signatures

An encryption-free technique for enabling the self-authentication of value documents (including personal and commercial checks) presented at a point of purchase or financial institution. Certain data contained on the value document may be signed with a first digital signature and authenticated with a public key certificate issued from a trusted certificate authority. The signed data and public key certificate are stored on the value document, preferably in a two-dimensional bar code data format. In the case of certain personal value documents (such as checks, credit cards, passports, birth certificates, Social Security cards, etc.), a unique personal identification number (PIN) also may be included in the document data that is signed by a second digital signature. At a point of purchase, a merchant or teller can scan and read the data stored in the two-dimensional bar code and other magnetically recorded information, and together with the PIN the customer provides, can authenticate the value document thus presented using the second digital signature. Alternatively, if the customer is not present, if the personal value document contains the second digital signature, the document may be verified using a PIN-generating algorithm or other method that generates all permutations of PINs. The first digital signature alone may be used to authenticate selected data within the personal value document even when the PIN is not available. Similarly, in the case of a commercial value documents, authentication of pre-printed data may be based entirely upon only the first digital signature.
