  • Publication number: 20140372681
    Abstract: The present invention relates to an apparatus and method for indicating flash memory life. While data is being stored in a flash memory, the number of writes in a plurality of blocks of the flash memory increases. The amount of flash memory life is calculated on the basis of the number of write times in the plurality of blocks. The calculated amount of life can be transmitted to a host. In addition, when the calculated amount of life is greater than a threshold value, a signal providing notice that the life of the flash memory has reached a dangerous level can be output.

  • Patent number: 8863177
    Abstract: A system for inserting advertisement data into broadcast data and method thereof are provided. The system and method can output advertisement data to a certain portion of a lower end of a screen image of the new channel for a certain time when a current channel is changed to a different broadcast channel according to a viewer's intention while the viewer is viewing a broadcast program, thus minimizing viewer's reluctance to the advertisement output, reducing the burden of an advertiser, and guaranteeing a visual continuity of a broadcast program desired to be searched. Using the present invention, when channels are switched for searching for broadcast programs or when power is turned on or off, advertisement data can be output to the same screen while outputting a pertinent broadcast program, thereby exposing the advertisement data without interrupting the broadcast program.

  • Patent number: 8805759
    Abstract: A system and method are provided for psychographically profiling a target population of individuals, programmably implemented in a server apparatus. The psychographic segmentation portion includes a questionnaire processing part, a segment solution part, and a typing tool part. The questionnaire processing part acquires a plurality of responses to a predetermined set of questionnaire questions by an initial pool of target population members. The questionnaire processing part uses a combination of weighted statistical methodologies to arrive at a rule-based decision on whether the question would serve as a good wedge variable. Optionally, the rule based decision is then compared to an expert's opinion and the weights and threshold parameters of the weighted statistical combination are adjusted accordingly to more accurately match the expert's decision. The identified wedge variables are used for effectively segregating the target population into groups of homogenous individuals.
