20100045686 | Display Method Applied to Electrophoretic Display and Corresponding Electrophoretic Display - In a display method applied to an electrophoretic display, the electrophoretic display has a first memory, a second memory and an electrophoretic display panel. A plurality of data is stored in the first memory according to a predetermined sequence. The display method includes the following steps. Firstly, whether a first datum of the data is stored in the second memory is determined. Next, the first datum is read out from the first memory and stored in the second memory if the first datum is not stored in the second memory. Next, the first datum stored in the second memory is displayed on the electrophoretic display panel. Next, a second datum before the first datum and/or a third datum after the first datum are/is read out from the first memory and stored in the second memory during displaying the first datum on the electrophoretic display panel. | 02-25-2010 |

20120274482 | PARKING LOT MANAGEMENT SYSTEM - A parking lot management system comprising a computer host, a handheld device, an entrance sensor, an entrance camera, an entrance stop, an exit sensor, an exit camera, and an exit stop is disclosed. The handheld device interactively transmits data with the entrance sensor and the exit sensor by near-field communication techniques. Each of the entrance camera and the exit camera takes a photo and acquires a license plate number of a vehicle and communicates this information with the computer host. After the computer host confirms and verifies some specific data, the computer host sends instructions to the entrance stop or the exit stop for allowing the vehicle to either enter or exit a parking lot. When exiting the parking lot, the parking fee is paid by the electronic wallet of the handheld device. | 11-01-2012 |

20110147761 | TWO-TERMINAL SWITCHING DEVICES AND THEIR METHODS OF FABRICATION - Two-terminal switching devices characterized by high on/off current ratios and by high breakdown voltage are provided. These devices can be employed as switches in the driving circuits of active matrix displays, e.g., in electrophoretic, rotating element and liquid crystal displays. The switching devices include two electrodes, and a layer of a broad band semiconducting material residing between the electrodes. According to one example, the cathode comprises a metal having a low work function, the anode comprises an organic material having a p+ or p++ type of conductivity, and the broad band semiconductor comprises a metal oxide. The work function difference between the cathode and the anode material is preferably at least about 0.6 eV. The on/off current ratios of at least 10,000 over a voltage range of about 15 V can be achieved. The devices can be formed, if desired, on flexible polymeric substrates having low melting points. | 06-23-2011 |
