Abstract: A steerable, magnetic dipole antenna for Measurement-While-Drilling (MWD) or Logging-While-Drilling (LWD) applications. The antenna elements use a hole arrangement in addition to grooves in a steel tool body, which is typically a drill collar. This antenna embodiment is extremely robust, meaning that does not significantly reduce the structural integrity of the tool body in which it is disposed. The antenna embodiment is also relatively wear resistant. The resultant magnetic dipole generated by this antenna is also electrically steerable in inclination angle from a common origin. A variable dipole moment inclination angle combined with independently measured tool rotation orientation during normal drilling allows the antenna to generate a magnetic dipole moment that may be directed at any three dimensional angle and from a common origin point at the centroid of the antenna.

Abstract: Systems and methods are described for better assessing risk associated with cashing second-party checks and other negotiable instruments. The systems and methods make use of information about authenticating marks, such as watermarks, bar codes, insignia, background patterns, and the like, from a check in order to better assess the legitimacy and cashability of the check. In various embodiments, information about an authenticating mark may be compared to stored information about an expected configuration for the authenticating mark. In various embodiments, a gradated risk score may be generated based at least in part on the comparison. In various embodiments, the risk score may be combined with risk scores that are descriptive of other aspects of a check cashing transaction to calculate a risk score for the transaction as a whole. In some embodiments, the transaction risk score may be used to generate an accept/decline recommendation for the transaction.

Abstract: Most financial transactions involving check deposits and cashing at automatic teller machines are often associated with high risk. Although conventional security measures for many automatic teller machines record financial transactions, the recorded events are typically viewed after suspicious or criminal activity has already occurred. Therefore, a financial institution may not know in advance whether requested financial transactions are of suspicious or fraudulent intent. The present teachings relate to a method of scoring customers prior to authorization in a manner so as to identify suspicious behavior or suspicious activity. The method also relates to marking suspicious individuals by storing related transaction information, such as biometric data, in a database for purposes of verifying identification information and scoring the validity of future financial transactions.

Abstract: Systems and methods are described for using a point-of-sale device at a check-cashing entity to obtain information about one or more authenticating marks, such as watermarks, bar codes, background patterns, color schemes, insignia, security validation numbers, or the like, from a second-party check or other negotiable instrument presented for a proposed check-cashing transaction. In various embodiments, the authenticating mark information may be compared to stored information about expected configurations of authenticating marks as part of a risk assessment of the check. In various embodiments, the point-of-sale device transmits authenticating mark information to a check authorization system. The point-of-sale device may receive an accept/decline recommendation for the transaction from the check authorization system, based at least in part on the obtained authenticating mark information. The point-of-sale device may display a message about the recommendation to an operator of the device.

Abstract: Systems and methods are described for better assessing risk associated with cashing second-party checks and other negotiable instruments by using biometric information obtained from an individual who presents a check or other negotiable instrument in a check-cashing transaction. In various embodiments, the obtained biometric information may be compared with stored biometric information in order to enhance confidence in the accurate identification of the check presenter. In various embodiments, a gradated biometric risk score, based at least in part on the comparison, may be generated for the check-cashing transaction. In various embodiments, the biometric risk score may be combined with risk scores that are descriptive of other aspects of the check-cashing transaction to calculate a risk score for the transaction as a whole. In some embodiments, the risk scores may be used to generate an accept/decline recommendation for the transaction as a whole.
