Abstract: Methods and apparatus are disclosed provide various enhancements and/or improvements to the conventional shopping process used by brick-and-mortar stores. In some embodiments, a customer may use a mobile computing device, such as a smart phone, to select and pay for items in a brick-and-mortar store. Such shopping process may permit the customer to purchase numerous items without the using of shopping basket or a wheeled shopping cart. The shopping process may further permit the customer to pay for items and leave the store with such items without waiting in a checkout line.

Abstract: A system for acquisition, processing and display of gated SPECT imaging data for use in diagnosing Coronary Artery Disease (CAD) in nuclear medicine. The present invention provides a physician with two parameters for evaluating CAD: information relating to the distribution of blood flow within the myocardium (perfusion) and information relating to myocardium wall motion (function). One aspect of the present invention provides the physician with a display of functional images representing quantitative information relating to both perfusion and function with respect to selected regions of interest of the subject heart at end-diastole and end-systole segments of the cardiac cycle. The functional display consists of arcs of varied width depending on wall motion and color coded to illustrate degrees of myocardial perfusion for different pie shaped sections of a selected region of interest within a given short axis slice of reconstructed volume data.

Abstract: A floating battery feed circuit comprising a switching-mode, flyback power converter wherein a capacitor connected to a converter transformer winding develops a relatively low voltage used to energize the converter control circuitry. The converter control circuitry prevents the operation of the battery feed circuit unless the voltage developed by the capacitor is above a predetermined magnitude. The power converter advantageously operates in only a constant-power mode regardless of loop impedance.
