Abstract: A computerized system for providing article information to a customer, said system comprising an optical image acquisition device for acquiring an optical image of an area of interest (AOI) in which articles are display to a customer, a processor module operably in communication with the optical image acquisition device and for receiving an image input signal therefrom; and an output device in communication with the processor for providing an output signal to a customer: wherein upon the processor detecting the article being removed from the area of interest (AOI), the processor sends an output signal having article data associated with said article to said output device, and said output device provides an output to the customer of said article data.

Abstract: A computerized system (100, 200) for illuminating an article (280, 307, 308) on an anatomic site (305, 306) of a subject (270) includes: an optical image acquisition device (130, 230) for acquiring an optical image of a subject (270); a processor module (110, 210) operably in communication with the optical image acquisition device (130, 230) for receiving an image input signal (135) therefrom; and one or more light sources (150, 252, 254) operably in communication with the processor module (110, 210) for illuminating an anatomical site (305, 306) of the subject (270). One or more light sources (150, 252, 254) are controllably moveable by the processor module (110, 210), which sends a control signal (155) in conjunction with the image input signal (135) to one or more light sources (150, 252, 254), so as maintains illumination on the anatomical site (305, 306) of the subject (270) irrespective of movement of the subject (270).

Abstract: A torque-restoring element for an oscillator for a mechanical timepiece and having an oscillator frequency, said torque restoring element comprising a spiral spring body having a number N turnings with an inner terminal end for engagement with a rotational inertial element via a collet, and an outer terminal for engagement with a stationary cock element, and having a width, a height and a total arc length; wherein the spiral spring body includes a core formed from mono-crystalline silicon wafer oriented along the crystallographic axis <110>; and wherein the spiral spring body includes at least one peripheral coating of a material having a thermal elastic constant different from that of the core of the spiral spring body so as to maintain the oscillator frequency an oscillator including the torque-restoring element substantially insensitive to variations of ambient temperature.
