A mobile device is provided for imparting spatially articulable control to an application program. The device includes a display for presenting the GUI. A spatial detection unit is configured to detect spatial movement of the mobile device and provides an output responsive to the detected spatial movement. A data processor is configured to provide a platform for executable code, and, monitors and provides the output to a communication channel. Executable code executes on the platform of the data processor. The executable code includes, an interpreter library which is operably linked to the communication channel and is configured to implement communication with the data processor to receive the output. The interpreter generates events relative to the interpreter library. A plug-in has an interface cooperatively linked to the interpreter library to receive corresponding generated events. The generated events are provided to a script interface of the plug in. A browsing program is cooperatively linked to the plug-in and configured to receive the generated events therefrom. In this way, the script interface supports a scripting environment such that the browsing program is controlled on the display in response to the spatial movement of the mobile device.

Compared with the traditional image search engine, the invention adds the clustering idea to the image retrieval. The keywords are semantically analyzed to form different subjects; meanwhile, the images are also analyzed in visual characteristic level to cluster similar images in a class, and finally the retrieval results are displayed for the user in classification mode through a concise and clear interface, so as to help users quickly and efficiently find out the required target image from the retrieval results with unsorted subjects.

Methods of depositing a tantalum-nitride (TaN) diffusion barrier region on low-k materials. The methods include forming a protective layer on the low-k material substrate by performing plasma-enhanced atomic layer deposition (PE-ALD) from tantalum-based precursor and a nitrogen plasma in a chamber. The protective layer has a nitrogen content greater than its tantalum content. A substantially stoichiometric tantalum-nitride layer is then formed by performing PE-ALD from the tantalum-based precursor and a plasma including hydrogen and nitrogen. The invention also includes the tantalum-nitride diffusion barrier region so formed. In one embodiment, the metal precursor includes tantalum penta-chloride (TaCl₅). The invention generates a sharp interface between low-k materials and liner materials.

A method of joining dissimilar materials having different ductility, involves two principal steps: Decoration of the more ductile material's surface with particles of a less ductile material to produce a composite; and, sinter-bonding the composite produced to a joining member of a less ductile material. The joining method is suitable for joining dissimilar materials that are chemically inert towards each other (e.g., metal and ceramic), while resulting in a strong bond with a sharp interface between the two materials. The joining materials may differ greatly in form or particle size. The method is applicable to various types of materials including ceramic, metal, glass, glass-ceramic, polymer, cermet, semiconductor, etc., and the materials can be in various geometrical forms, such as powders, fibers, or bulk bodies (foil, wire, plate, etc.). Composites and devices with a decorated/sintered interface are also provided.

The present invention generally relates to a magnetic head having a thinner intermixing layer between a barrier layer and a magnetic layer. The method of making the magnetic head is also disclosed. The thinner intermixing layer in the magnetic head is formed by cooling the barrier layer in an atmosphere having a temperature of below 0 degrees Celsius prior to depositing the magnetic layer on the barrier layer. The thinner intermixing layer leads to a sharp interface between the barrier layer and the magnetic layer, which leads to an increased MR.

In the production of glycidyl methacrylate from an alkali metal salt of methacrylic acid and epichlorohydrin, at least one water-soluble polymerization inhibitor is added at an appropriate stage of the production. The addition of the water-soluble polymerization inhibitor prevents the formation of insoluble solid matters to increase the efficiency of phase separation in the washing operation for removing a by-produced salt and form a clear interface between the phases, thereby minimizing the recovery loss. In addition, the troubles such as clogging of pipe lines of production apparatus and equipment for waster water treatment can be avoided.
