| 20090153064 | Electronic Circuit for Driving Electroluminescent Display - An electroluminescent circuit for driving an electroluminescent display having a plurality of segment electrodes and a common electrode. The circuit comprises a DC power supply, an output terminal for each of the segments and common electrodes and at least one supply half H-bridge for connecting at least one of each of the segment electrodes and the common electrode selectively to one of the DC supply and a reference voltage. Each supply half H-bridge comprises a top switch and a bottom switch in series having a junction between them. The top switch is connected to the DC supply and the bottom switch is connected to a reference voltage. A discharge circuit is provided for selectively discharging the electroluminescent display, the discharge circuit comprising a discharge half H-bridge in which a top switch is connected to the DC supply and to a discharge path. | 06-18-2009 |

| 20090073156 | Drive Circuits for Capacitive Loads - A drive circuit for driving electroluminescent (EL) segments and polymer dispersed liquid crystal (PDLC) segment of a display. The circuit may include a flyback converter for generating an A.C. output voltage, a first switching circuit for selectively connecting the output voltage to the EL segments, and a second switching circuit for selectively connecting the output voltage to the PDLC segments. In order to drive the EL segments and PDLC segments at the required frequencies, the polarity of the output voltage applied to the PDLC segments is swapped at a frequency lower than the frequency at which the polarity of the output voltage is swapped for the EL segments. In this way, only a single high voltage power supply is required to drive both the EL and PDLC segments. | 03-19-2009 |

| 20090273737 | Electroluminescent Displays - An electroluminescent display of the type having a switchable electroluminescent (EL) material backlight mounted behind a mask defining the information to be displayed. The mask is constructed as a layer of physically-stabilised Liquid Crystal (LC) material switchable to define the information to be displayed. The LC mask and the EL backlight are constructed as a single entity | 11-05-2009 |
| 20110057910 | DRIVING DISPLAYS - A method of driving a display, wherein the display comprises a layer of electroluminescent material (EL) and a layer of physically-stabilised liquid crystal (LC) wherein the layers of EL and LC are powered by a common set of electrodes. The method comprises driving the common electrodes with a voltage waveform which is substantially a truncated triangular waveform. | 03-10-2011 |

| 20100224513 | Tissue Product with Sacrificial Top Sheet for Pop-Up Dispensing - In order to improve the reliability of cleanly dispensing the first tissue in a pop-up dispensing tissue container, a relatively high strength sacrificial top sheet is interfolded with the tissue clip. The sacrificial top sheet is adhered to the underside of a removable surfboard in the top of the container, such that when the surfboard is removed to access the tissues, the sacrificial sheet is simultaneously removed, which causes the first tissue to pop up into a ready position for subsequent dispensing by the user. | 09-09-2010 |

| 20100107350 | Portable rolled wiping product - A portable rolled product containing a small roll of sheets, such as tissues or wet wipes, is particularly useful for uses outside the home. The roll of sheets is contained within a flexible package, such as a plastic film wrapper, having a roll housing portion and an extended dispensing portion or channel through which the user withdraws the product. After the desired amount of the sheets is withdrawn, the extended dispensing channel can be folded back around the roll housing portion of the package for storage until further use. | 05-06-2010 |

| 20100084564 | IMAGING APPARATUS - An imaging apparatus for x-rays includes a scintillator, overlying an array of imaging pixels on a substrate, and at least one trigger pixel array externally peripheral to the array of imaging pixels on the substrate such that the trigger pixel array is not substantially overshadowed by the scintillator from incident x-ray radiation. A layer substantially impervious to light but transparent to x-rays overlays the trigger pixel array, such that the trigger pixels are unresponsive to light but triggered by direct hits from incident x-ray photons. | 04-08-2010 |
