Abstract: A system may include an ultrasound probe and a controller unit configured to communicate with the ultrasound probe. The controller unit may be further configured to select an aiming mode for an ultrasound probe; detect a target of interest; determine a centroid for the detected target of interest; display a center indicator based on the determined centroid; detect that the center indicator is within a threshold number of pixels or distance of a centerline of a field of view of the ultrasound probe; and highlight the generated center indicator, in response to detecting that the center indicator is within the threshold number of pixels or distance of the centerline.

Abstract: The invention concerns an interactive television service in which multiple broadcasting facilities are interconnected through a single broadcast site so that each broadcast facility may interact freely with one another. A method is provided to allow a single broadcasting site to originate a broadcast and retain complete control of that broadcast in which all participating broadcasting sites can engage in two-way audio and full motion video discourse with the originating site as well as with all participating sites during the course of the broadcast. The method utilizes only two broadcast frequencies.

Abstract: A counter electrode structure of a transition metal electrochromic compound for use in an electro-optical device, which is useful in control of visible and infrared absorption by windows, in data display devices and the like, typically comprising in sandwich arrangement a pair of electrodes, and disposed therebetween, a layer of transition metal electrochromic compounds and a semi-solid highly conductive sulfuric acid gel electrolyte, one of the electrodes being said counter electrode. The gel exhibits good conductivity, stability and compatibility with the electrochromic layers. The present counter electrode is more efficient and has a longer lifetime.
