Abstract: A device for focusing a light beam comprises a optical assembly comprising at least one focusing lens and/or mirror, a support structure which supports the optical assembly, a magnetic actuator configured to move the optical assembly with respect to the support structure along a moving direction substantially parallel to an optical axis (X) of the optical assembly and at least one position sensor configured to provide an indication of the position of the optical assembly with respect to the support structure. The magnetic actuator comprises at least one permanent magnet integrally associated with the optical assembly and at least one first electrical winding integrally associated with the support structure and configured to cause flowing of an electric current within it, wherein the electrical current interacts with said at least one permanent magnet and causes the movement of the optical assembly along said moving direction until the optical assembly is brought to a desired focusing position.

Abstract: An imaging device has a focusing device flanked by electromagnets such that a magnetic levitation between the electromagnets and permanent magnets in the focusing device cause the focusing device to rotate about an axis. This rotation causes the optical axis of the focusing device to read an extended reading field beyond the ordinary reading field when the focusing device is in a balanced magnetic levitation position.

Abstract: A machine readable symbol reader can include a variable orientation scan engine and features to vary the orientation of the scan engine with respect to a housing of the reader to maintain an orientation of the scan engine in a global sense while an orientation of the rest of the reader including the housing changes. Such a machine readable symbol reader can be used in machine-readable symbol readers such as laser scanning machine readable symbol readers, smartphones with barcode readers attached, barcode scanners, optical imaging scanners, cameras, mobile computers, or for machine vision generally.
