  • Patent number: 8235293
    Abstract: Barcodes stored by mobile devices can be used in commerce. In sending barcode data optically from a display backlight of a mobile communication device to a barcode scanner optical receiver, the transmitted data bit time needs to be compatible with the frequency range the barcode scanner is designed to receive. The disclosed methods and mobile devices can send barcode data optically at different frequencies from a modulated display backlight to different models/makes of laser barcode scanners that may be used at a point of sale (POS). The disclosed are methods and devices for processing the bit time mix choices make a determination of bit time mix choices based upon predetermined criteria. Location of the device is an example of predetermined criteria. A location may have a particular bit time mix signature that may be accessed, for example, in a look up table.

  • Patent number: 7672641
    Abstract: An electronic device (100) having at least a first portion (102) and a second portion (104) is disclosed. The first portion is joined to the second portion by a mechanical connection. The electronic device (100) includes a first communication unit (106) present on the first portion (102), and a second communication unit (108) present on the second portion (104). The first communication unit (106) and the second communication unit (108) provide a first link for internal data communication between the first portion (102) and the second portion (104), when communicatively engaged with each other. Further, at least one of the first communication unit (106) and the second communication unit (108) provide a second link for external data communication with an external device when the first communication unit (106) and the second communication unit (108) are not communicatively engaged with each other.

  • Patent number: 7339636
    Abstract: A color display and solar cell device (100, 300, 500), and methods for fabricating and operating the device. The device (100, 300, 500) includes a transparent light source (140, 340, 540) located behind a liquid crystal display (105, 305, 505) that includes a switchable transflector layer (145, 345, 545). In a first embodiment, the liquid crystal display (105) also includes a tri-color pixelized filter (115), the switchable transflector (145) is a switchable broadband transflector, and the transparent light source (140) is a white light source. In a second embodiment, the switchable transflector layer (345) is a tri-color selectable transflector and the transparent light source (340) is a tri-color selectable light source. In a third embodiment, the switchable transflector layer is a switchable broadband transflector and the transparent light source is a tri-color selectable light source.

  • Patent number: 7053799
    Abstract: An illuminated keypad (400) includes a substantially transparent keypad (420) having a plurality of actuator buttons (412), a plurality of switches (404) residing substantially and correspondingly below the plurality of actuator buttons, a display laminate layer (415) residing between the plurality of actuator buttons and the plurality of switches, and a light source (417) reflectively illuminating a pattern of a symbol on the laminate layer by radiating light through the substantially transparent keypad. The display laminate can include a driver layer (406) having a conductor pattern configured in the pattern of the symbol to be displayed on the substantially transparent keypad, a transparent conductor layer (410), and an electrically active ink layer (408) disposed between the transparent conductor layer and the driver layer.
