Abstract: A system having an approach for prioritizing targets for an order of capturing the targets photographically or otherwise. Prioritizing is based on cost of obtaining or capturing the target for viewing or photographing in high resolution. One acquisition mechanism is for obtaining a wide field of view of a scene of targets and another acquisition mechanism is for obtaining a narrow field of view of a target for capture. The cost for prioritizing is based on the time that the narrow field of view acquisition mechanism takes to pan and tilt to get a close-up image of a target divided by the width of the target. The targets may be faces of people.

Abstract: Thermally stable ultra-hard compact constructions comprise a polycrystalline diamond body substantially free of a catalyst material, and a substrate that is joined thereto. The substrate can be ceramic, metallic, cermet and combinations thereof, and can be joined to the body by a braze material or other material that forms an attachment bond at high pressure/high temperature conditions. The body and substrate are specially formed having complementary interfacing surface features to facilitate providing an improved degree of attachment therebetween. The complementary surface features can in the form of openings and projections, e.g., one of the body or substrate can comprise one or more openings, and the other of the body or substrate can comprise one or more projections, disposed within or extending from respective interfacing surfaces. The complementary surface features operate to resist unwanted delamination between the body and substrate, thereby extending effective service life of the construction.

Abstract: A cutting element is provided having a substrate and an ultra hard material cutting layer over the substrate. The cutting layer includes a surface portion for making contact with a material to be cut by the cutting element.

Abstract: A method for designing a drill bit including selecting a characteristic associated with a failure mode. A first value of the characteristic of a first cutting element and a second value for the characteristic of a second cutting element are determined. The method also includes determining whether a difference between the first value and the second value is within a predetermined range. A cutting element design parameter for the first cutting element is adjusted if the difference is outside the predetermined range. The determining first and second values, determining the difference, and adjusting a cutting element design parameter are repeated until the difference is within the predetermined range.

Abstract: Obstructive material is removed from a stent by modified electrosurgical ablation. A modified electrosurgical device having at least one electrode is positioned within the stent, and current is supplied to the electrode. The electrode is prevented from physically contacting the stent, such as by being situated within a groove on the device. The stent may, but need not be, grounded to the current source. The device may be properly positioned within the stent by using ultrasound transducers, fiber optics, or other means. Additionally, the device may be positioned by including at least two electrodes, and measuring the impedance therebetween, as the impedance will be relatively low when both electrodes are within a conductive stent. Therapeutic fluid may be supplied through the catheter, and energy may be supplied to increase the activity of the fluid.
