  • Patent number: 9389264
    Abstract: An apparatus and method for preventing erroneous detection of a jack is provided. The apparatus includes a detection terminal configured to detect whether a jack plug of an earphone is inserted into the jack, a comparator configured to compare a voltage input from the detection terminal with a predetermined reference voltage and provide a comparison result signal to a baseband module, a resistor with a certain resistance value, being interposed between the detection terminal and the comparator to keep a voltage of a high signal not to be lowered than the predetermined reference voltage when the jack is conducted due to conductive particles flowed into the jack.

  • Publication number: 20090135579
    Abstract: A touch pad including an ElectroMagnetic Interference (EMI) shielding plate and method for detecting a touch on the touch pad is provided. The touch pad includes a touch plate for generating, when a touch is generated on a surface of the touch plate, a change of a physical property, a touch sensor coupled to the touch plate for detecting a position of the generated touch by measuring the change of the physical property, and an EMI shielding plate disposed adjacent to or attached to a surface of the touch plate and formed with a plurality of openings. The density of the openings formed at a position of the EMI shielding plate increases as the position becomes farther from the touch sensor. Accordingly, the touch pad having an EMI shielding plate can more accurately detect a touch generated at any position close to or remote from the touch sensor of the touch pad, and thereby increase user convenience of a portable terminal.

  • Patent number: 7428420
    Abstract: A quick paging method for improving a standby time of a mobile terminal in a shadow area or a hand off region where the mobile terminal receives a pilot signal from a base station over a pilot channel and a quick paging signal from the base station over a quick paging channel, and measures strength of the pilot signal and strength of the quick paging signal. When the pilot signal strength does not exceed a predetermined threshold value, the mobile terminal determines that one or more paging indicator bits transmitted from the base station over the quick paging channel are erased, and informs the base station of the pilot signal strength and the quick paging signal strength. The base station receives the pilot signal strength and the quick paging signal strength from the mobile terminal.

  • Patent number: 7212831
    Abstract: A quick paging method for improving a standby time of a mobile terminal in a shadow area or a handoff region where the mobile terminal receives a pilot signal from a base station over a pilot channel and a quick paging signal from the base station over a quick paging channel, and measures strength of the pilot signal and strength of the quick paging signal. When the pilot signal strength does not exceed a predetermined threshold value, the mobile terminal determines that one or more paging indicator bits transmitted from the base station over the quick paging channel are erased, and informs the base station of the pilot signal strength and the quick paging signal strength. The base station receives the pilot signal strength and the quick paging signal strength from the mobile terminal.
