Abstract: Systems, methods and apparatuses for authenticating a user via a machine-readable code arranged on a reusable payment device and a computing device are provided. An image of the machine-readable code may be received from a computing device, such as a mobile device. If it is determined that a match exists between a user associated with the mobile device and a user associated with the machine-readable code and/or reusable payment device, a user may be authenticated and may be provided with account information and/or account functionality. In some examples, the authentication may be used to pre-populate payment information during a transaction.

Abstract: A flexure carriage assembly (24) has a carriage (25) formed of a substantially rigid material. The carriage has four elongate columns (32A, 32B, 32C, 32D) arranged spaced apart and parallel to one another. Each of the elongate columns has first and second ends. The flexure carriage (25) has four first cross members disposed between adjacent pairs of elongate columns and arranged to interconnect the first ends. The flexure carriage also includes four second cross members (38A-D) arranged between adjacent pairs of elongate columns and arranged to interconnect the bottom ends. The elongate columns and first and second cross members define a three-dimensional rectangular structure. The flexure carriage also has disposed centrally between the four elongate columns a translating section (29) spaced equidistant between the first and second ends of the columns.

Abstract: The invention features a method for determining a geometric property of a test object, the method including: interferometrically profiling a first surface of the test object in a first coordinate system; interferometrically profiling a second surface of the test object in a second coordinate system different from the first coordinate system; providing a relationship between the first and second coordinate system; and calculating the geometric property based on the interferometrically profiled surfaces and the relationship between the first and second coordinate system. In some embodiments, the relationship may be determined by using calibrated gage blocks or by using a displacement measuring interferometer. Corresponding system are also described.
