International Classification:

G01N 27/60
G01R 29/12
G06K 19/02

US Classification:

324456, 324457, 235488

Abstract:

Methods of performing electrostatic discharge testing on a transaction card are disclosed. A transaction card may be placed on an insulated surface. A grounding probe may be placed at a first location on the transaction card. A discharge probe may be charged to a known voltage level. The discharge probe may then be discharged at a second location on the transaction card. A discharge wave shape may be recorded from the ground probe, and one of a pass condition and a fail condition may be assigned based on at least the value of the known voltage level as compared to a reference voltage level. The first location and the second location may each be selected from a plurality of areas on the transaction card.

International Classification:

G06F 1214

US Classification:

380206

Abstract:

A system, method, and data structure provide for securely synchronizing passwords and/or other information between systems. The password-related information is stored in the systems in a secure manner, and a user or some other, external agent participates actively in the transmission of a new password between systems. A password update file is communicated or shared between systems to synchronize passwords.

International Classification:

F01M 11/12
F01M 11/00
G01F 23/26
G07C 5/02

Abstract:

Embodiments provide an oil pan that includes an oil pan having a reservoir configured to hold oil and defined by one or more oil pan walls and an oil pan bottom. The oil pan includes one or more capacitance sensors coupled to a portion of the oil pan walls and configured to sense a capacitance. The oil pan includes a capacitance measuring unit electrically connected to the one or more sensors via one or more conductors and configured to receive each of the sensed capacitances via the one or more conductors and determine capacitance values for each of the sensed capacitances. The oil pan also includes a processor configured to receive the capacitance values and determine the oil level in the oil pan based on the capacitance values.
