Abstract: The invention relates Tunable prism (1) for optical image stabilization, comprising the components: A container (2) that comprises a membrane (6) comprising at least a transparent portion, the container (2) further comprising a transparent rigid bottom portion (5) facing the membrane (6), wherein the membrane (6) is connected to the bottom portion (5), and wherein the container (2) encloses a volume (7) that is filled with a transparent fluid (3); A transparent window (8) arranged on the membrane (6), wherein the membrane (6) comprises a deformable portion (6a) extending around an outer edge (8a) of the window (8), such that the window (8) can be tilted around a first and/or a second axis (201, 202) with respect to the bottom portion (5). The invention further relates to an imaging system (50) comprising the tunable prism (1).

Abstract: Business transactions or other events may be structured as a series of database-objects formed of combinations of sub-objects which in turn may depend on yet a lower level of objects. By creating object templates for the objects that progressively group inter-correlated data and inter-correlated objects, large amounts of event data may be captured with modest data storage requirements. The system is particularly well suited for capturing sales events comprised of a large range of data of different attributes.
