    摘要: A device detects multi-spectral imaging by using scan elements. The device may include an illumination module and a detection module to detect light scattered from an object illuminated by the illumination module. The device may also include an array of light sources to produce light at a plurality of different wavelengths, and create a line of illumination with each of the different wavelengths. The light detection may be applied to authenticate and validate documents, such as banknotes moving along a document conveyer.

    摘要: The present invention describes a method for recognizing alphanumeric strings spoken over a telephone network wherein individual character recognition need not be uniformly high in order to achieve high string recognition accuracy. Preferably, the method uses a processing system having a digital processor, an interface to the telephone network, and a database for storing a predetermined set of reference alphanumeric strings. In operation, the system prompts the caller to speak each character of a string, beginning with a first character and ending with a last character. Each character is then recognized using a speaker-independent voice recognition algorithm. The method calculates recognition distances between each spoken input character and the corresponding letter or digit in the same position within each reference alphanumeric string. After each character is spoken, captured and analyzed, each reference string distance is incremented and the process is continued, accumulating distances for each reference string, until the last character is spoken. The reference string with the lowest cumulative distance is then declared to be the recognized string.

    摘要: A system and method for iterative sequential carrier acquisition for estimating and correcting large carrier frequency offsets without adding significantly to receiver complexity or preamble length. A coarse frequency estimation is performed during a brief carrier acquisition phase that is completed during a reasonably short preamble, and then the system hands frequency control to the nominal carrier frequency & phase tracking of a phase-locked loop (PLL) circuit. The present disclosure generally includes an initialization mode, a pre-lock scan mode, an iterative search mode and a termination mode.

    摘要: A method for enabling a caller to obtain access to one or more services via a telephone network by speaking a password is described. The method begins by establishing at least one predetermined threshold value for a speaker verification signal. For each spoken character of the password, the method generates a set of parameters using a voice verification feature transformation. After entry and recognition of the password, the sets of parameters are used to generate a speaker verification signal for the password. Upon the occurrence of a predetermined call condition, the predetermined threshold value is adjusted to increase the level of security in the verification algorithm. If the signal verification signal for the password has a predetermined relationship with respect to the adjusted threshold value, the caller's identity is accepted. If not, the caller may be asked to answer certain personal questions before his or her identity is accepted.

    摘要: A collision handling receiver for use in a data communication network. The collision handling system and method comprises collision handling receivers together with transmitters inserting pseudo-random delays. Accordingly, multiple sources may transmit simultaneous messages to a receiver so that the messages arrive with varying signal levels and times of arrival. The receiver sorts the symbols into separate sequences by grouping together symbols having similar time of arrival. In addition, the receiver retains the sequences with sufficiently reliable symbol detection, for example, when 75% of the symbols in a sequence are detected with sufficient quality. Receiver then ranks the retained transmitters by received signal level and decodes the messages from transmitters with highest received signal level.
