    摘要: A method and apparatus for determining the distance between transitions from a first logical state to a second logical state stored on a medium (i.e., a document). This determination is used to precisely characterize the information pattern in order to authenticate the information and the medium on which the information is stored. The invention uses a reader having a leading and trailing read apparatus which allow information to be read simultaneously from two or more locations spaced a known distance apart. The distance between the centerlines of each read apparatus is preferably an odd integer multiple of one half the distance between logical clock transitions. The distance between a first transition at the leading read apparatus and a next transition at the trailing read apparatus is used as a reference (i.e., the “Reference Value”). The Reference Value is compared with the distance between the first transition and the next transition on the medium (i.e., the “Jitter Value”). Detection of an deviations in spacing between transitions is unaffected by variations in the velocity of the medium with respect to the reader.

    摘要: The present invention is directed to a combination wireless and wired token access distributed network and system comprising a secure locator network (SLN) system having one or more network system controllers (NSCs), and where the data collection and transmission nodes (DCTNs) are magnetic stripe card readers or chip card readers that broadcast the data read from the data token card to data access points (DAPs) using wireless communications. The DAPs store the data in a table which is made available for TCP/IP access. The NSCs contain processing software which poll the DAPs at regular intervals, captures the resulting data table, parses said data and stores it in a database. This data is available for applications residing on the NSCs. If the SLN is connected to a larger network, such as a global computer network, applications on other linked computers or data processors can access the data for processing, depending upon security considerations and protocols. The system can be readily used in restaurant service applications, gaming tracking applications and entry access applications, to provide enhanced security and increased efficiency in service.

    摘要: A method and apparatus for reading and writing data to a medium which moves at an uncontrolled velocity relative to a read/write apparatus with which the data is read and written. The read/write apparatus comprises one write head and two read heads. The first read head is spaced apart from the second read head by an odd integer multiple of one half of a bit cell. The two read heads read preexisting data from the medium and generate a write clock which is used to synchronize a write operation using the write head. Delay logic ensures that the write head is over that portion of the medium on which new data is to be written. By measuring the amount of time between detection of a transition at the first read head and detection of that transition at the second read head, the velocity of the medium with respect to the read/write apparatus is determined and the amount of time that must elapse between the reading of old data and the writing of new data which overwrites the old data is determined. A write clock decoder receives a pulse associated with each transition read by either the first or the second read head, and outputs a write clock synchronized to the velocity of the read/write apparatus with respect to the medium based upon these received pulses. By spacing the two read heads apart by an odd multiple of one half the bit cell, either the first or the second read head will always detect a transition at each half bit cell. Thus, the write clock will have a transition each half bit cell.
