  • Patent number: 9552779
    Abstract: An electronic apparatus and a display backlight control method are provided. The electronic apparatus includes a display, a processing unit, a read-only memory and a backlight controller. The read-only memory stores a basic input output system (BIOS) and a setting table. The setting table includes a plurality of backlight setting values corresponding to each of the displays. When the processing unit executes the BIOS, the processing unit identifies an identifier corresponding to the display connected to the electronic apparatus, so as to obtain the backlight setting values corresponding to the display according to the identifier and the setting table. Then the processing unit provides the backlight setting values to the backlight controller, and the backlight controller controls the backlight power of the display according to the backlight setting values.

  • Patent number: 8849272
    Abstract: An apparatus for coordinating radio activities in different radio access technologies (RATs) is provided. A first RAT module performs a first channel activity, related to a first RAT, for transmitting or receiving information to or from a first cellular network by using an antenna, and requests that a measurement activity, related to the first RAT, is to be performed for measuring signal power of a serving cell and/or at least one neighbor cell in the first cellular network by using the antenna. A second RAT module requests that a second channel activity, related to a second RAT, is to be performed for transmitting or receiving information to or from a second cellular network by using the antenna. An arbiter schedules performance of the measurement activity between the first and second channel activities.

  • Patent number: 8515489
    Abstract: A communications apparatus with a processor coupled to a first RAT module in a packet transfer mode for data transfer, a second RAT module in an idle mode and a radio transceiver are provided. The processor receives a reservation request requesting permission to use the radio transceiver for performing a first radio activity from the first RAT module, and determines whether to provide a gap interval during the data transfer of the second RAT module for the first RAT module to use the radio transceiver according to a type of a second radio activity to be preformed by the second RAT module which collides with the first radio activity. When the gap interval is determined to be provided, the second RAT module is unable to use the radio transceiver for performing the second radio activity and the data transfer of the second RAT module is suspended during the gap interval.

  • Patent number: 5749666
    Abstract: An expanding file includes an upper cover, a bottom cover and a plurality of plates which are disposed between the upper cover and the bottom cover. A flexible connecting member connects each pair of adjacent upper cover plates and bottom cover. A fastener binder which has a base portion having two ends is fixedly attached to at least one of the upper cover and the bottom cover by way of ultrasonic welding. Deformable extension parts extend from each of the two ends of the base portion such that a document can be securely positioned in the expanding file by extending the two extension parts through holes defined in the document and then pressing the extension parts toward the document.
