  • Publication number: 20140158189
    Abstract: A tandem solar cell includes a bottom solar cell having an energy bandgap with Eg1 and at least a top solar cell having an energy bandgap Eg2, the energy bandgaps satisfying a relationship Eg1<Eg2. The bottom and top solar cells are vertically stacked and electrically interconnected in series in which an area of the bottom solar cell is larger than an area of the top solar cell in an appropriate ratio to provide for a substantially current matched photovoltaic device for operation in a 2-terminal configuration. This tandem structure may contain more than two (2) cells and each cell may be composed of more than one solar cell. In this case the top solar cell has the largest bandgap, the bottom solar cell has the smallest bandgap, and intervening solar cells have intermediate bandgaps that descend in magnitude from the top to the bottom solar cell.

  • Patent number: 8750263
    Abstract: Intra-enterprise wireless handset (WH) calls between WHs operating in a wireless local area network (WLAN) are established directly between the WHs via a call connection that is maintained within the LAN without being routed through the cellular network (CN). This eliminates the cost of placing and maintaining calls through the CN for intra-enterprise calls, and also enables use of capabilities that are available in the enterprise telecomm equipment. Upon detection of a trigger condition, if and when it is more likely that a complete vertical handover (VHO) may be needed, the call connection between the WHs in the LAN is replaced by one that is routed through the CN. Thereafter, a VHO may occur (if at all) upon detection of a radio handover condition.

  • Patent number: 8723779
    Abstract: The present invention provides a tiled optical fiber display device structure which includes a light emitting diode (LED) backlit liquid crystal display (LCD). Light from the LCD enters an array of optical fibers that directs the light to a viewing screen. The optical fibers eliminate the use of energy absorbing color filters in conventional LCD's, and also enable the seamless tiling of multiple display modules.

  • Publication number: 20140055621
    Abstract: Technologies are generally described for automatically optimizing an efficiency of camera placement, numbers, and resolution in multi-camera monitoring and surveillance applications. In some examples, a fraction of a total area may be monitored at a higher resolution than the rest. Employing techniques such as combinatorial state Viterbi technique or combinatorial state trellis technique, a minimum number of cameras that provide the coverage at the needed resolution may be selected. Similarly, a number of points may be covered with at least a predefined number of cameras. For example, a subject of interest may be tracked in a public area, where specific camera(s) may be used to image the subject's face at a higher resolution than the background.

  • Publication number: 20130330754
    Abstract: The present application is directed to a novel approach for rapid, selective and sensitive detection of heavy metals using a solid-phase bioactive lab-on-paper sensor that is ink-jet printed with sol-gel entrapped reagents to allow colorimetric visualization of the enzymatic activity. The bioactive paper assay is able to detect a range of heavy metals, either alone or as mixtures, in as little as 10 min. The paper-based assay was immune to interferences from non-toxic metal ions such as Na+ or K+, could be used to detect heavy metals that were spiked into tap water or lake water, and provided quantitative data that was in agreement with values obtained by atomic absorption. The paper-based sensor is of value for rapid, on-site screening of trace levels of heavy metals in resource limited areas and developing countries.
