  • Patent number: 8280367
    Abstract: A mobile device receives, via a wireless network, a plurality of messages and stores message information of the messages in memory. Each message includes at least one correspondent address and conversation text with the at least one correspondent address, as well as metadata comprising an identifier for uniquely identifying the message at a server. The mobile device identifies whether a size of the message information has reached a first predetermined limit of the memory. Based on identifying that the size of the message information has reached the first predetermined limit, the mobile device deletes from the memory, automatically without user intervention, at least portions of the conversation text of some of the messages while retaining storage of the correspondent addresses and the metadata thereof. The mobile device also identifies whether the size of the message information has reached a second predetermined limit of the memory, which is greater than the first predetermined limit.

  • Patent number: 8130616
    Abstract: A method and a device of distinguishing blank area from non-blank area in an optical disc are provided. An input signal such as a DPD TE signal or RF ripple signal is first filtered to obtain a filtered signal. A subtracting operation of the input signal and the filtered signal is then performed to obtain a first signal. According to a peak value and a bottom value of the first signal, the first signal is processed into a second signal. By comparing the second signal with a reference signal, whether the currently read area is blank area or non-blank area can be discriminated. An indicating signal is outputted at a first value to indicate the blank area while the indicating signal is outputted at a second value to indicate the non-blank area.
