Electrode structures and methods for making the same are generally described. In certain embodiments, the electrode structures can include a plurality of particles, wherein the particles comprise indentations relative to their convex hulls. As the particles are moved proximate to or in contact with one another, the indentations of the particles can define pores between the particles. In addition, when particles comprising indentations relative to their convex hulls are moved relative to each other, the presence of the indentations can ensure that complete contact does not result between the particles (i.e., that there remains some space between the particles) and that void volume is maintained within the bulk of the assembly. Accordingly, electrodes comprising particles with indentations relative to their convex hulls can be configured to withstand the application of a force to the electrode while substantially maintaining electrode void volume (and, therefore, performance). Particles having indentations relative to their convex hulls also occupy a relatively small volume, compared to spheres or other particles including boundaries that fill substantially all of their convex hulls, allowing one to introduce a desired amount of void volume while reducing the percentage of volume within the electrode occupied by particulate material.

A graphics animation and compositing operations framework has a layer tree for interfacing with the application and a render tree for interfacing with a render engine. Layers in the layer tree can be content, windows, views, video, images, text, media or other type of objects for an application's user interface. The application commits state changes of the layers of the layer tree. The application does not need to include explicit code for animating the changes to the layers. Instead, after a synchronization threshold has been met, an animation is determined for animating the change in state by the framework which can define a set of predetermined animations based on motion, visibility and transition. The determined animation is explicitly applied to the affected layers in the render tree. A render engine renders from the render tree into a frame buffer, synchronized with the display. Portions of the render tree changing relative to prior versions can be tracked to improve resource management.

A technique is provided to determine whether a region within a web page is viewable to a user through a browser window. Often, browsers will only show part of a web page at given time, creating a difficulty in establishing whether a region of the web page, which may be an advertisement for example, is in view.

During magnification change from the wide-angle end to the telephoto end, the first to fourth groups are moved to always increase the distance between the first and second groups, always decrease the distance between the second and third groups, and change the distance between the third and fourth groups and the distance between the fourth and fifth groups. The third group includes, in order from the object side, at least a positive lens, a positive lens, a negative lens, and a positive lens, and satisfies condition expression (1) below: 25<νdD−νdA<70 (1), where νdA and νdD are Abbe numbers at the d-line of the most object-side lens A and the most image-side lens D.

A photographic lens and a photographic apparatus including the same are provided. The photographic lens includes a first lens including a convex surface toward an object side and having a positive refractive power, a second lens including a concave surface toward an image side and having a negative refractive power, a third lens having a positive refractive power or a negative refractive power, a fourth lens having a positive refractive power or a negative refractive power, a fifth lens including a convex surface toward the image side and having a positive refractive power, and a sixth lens including a concave aspherical shape with respect to an optical axis toward the image side and having a negative refractive power. The first to sixth lenses may be sequentially arranged from the object side to the image side.

A lens holder driving apparatus is disclosed. The lens holder driving apparatus includes a housing, an auto-focusing lens holder driving portion and a fixed portion. The auto-focusing lens holder driving portion includes an octagonal lens holder with a focusing coil, a positioning magnet mounted on the lens holder, a magnet holder with a magnet group including a bracket having a sidewall, a pillar projecting at the four corners of the sidewall of the bracket, and a first notch disposed at the pillar face to the focusing coil. The fixed portion includes a base having a sidewall, a FPC mounted on the sidewall of the base and a Hall element electrically connecting with the FPC inserted into the first notch for detecting the position of the positioning magnet so as to adjust the position of the lens holder.

The present subject matter relates to a method, system and device for connecting conduit to an enclosure. The method, system and device comprise a conduit adapter having a two-piece housing and an insert plate. The insert plate is interchangeable with other insert plates having various sized through holes. A conduit is attached to an insert plate via a suitable connector. The insert plate is selected to have an appropriately sized through hole for the conduit being attached. The selected insert plate having the conduit attached then is enclosed between the two halves of the housing of the conduit adapter. The conduit adapter is then secured in the entry port of the enclosure.
