Abstract: An impedance matching structure for a high-speed connector includes a pair of ground leads, a differential pair of signal leads, a ground plane, a first region in which the ground leads and the differential pair of signal leads are coplanar within a first plane, and a second region in which the differential pair of signal leads lies on the first plane and the ground plane lies on a second plane extending along the first plane. The impedance matching structure has a transition region between the first region and the second region. The ground leads are connected to the ground plane in the transition region. An impedance matching projection is arranged in the transition region and projects from a side of the differential pair of signal leads.

Abstract: Methods and systems are presented for a fraud risk score to be given to a merchant for a proposed transaction with a consumer. The fraud risk score is generated by a payment account service provider, such as a credit card processor, using information from a pending transaction as well as information from other payment accounts that the consumer holds to which the payment account service provider is privy. Various factors, including indicators of elevated risk in other payment accounts, are custom-weighted by the merchant for the score.
