  • Publication number: 20120194130
    Abstract: Systems and methods to detect a failure of a subset of component power packs within a multiple component rechargeable power pack. At least one parameter of a charging current that is provided for a time duration to a rechargeable power pack is determined. A measured capacity change quantity for the rechargeable power pack during the time duration is estimated. The measured capacity change quantity is compared, after the time duration, to an expected capacity change quantity that is based upon the at least one parameter. A determination is made that at least one component power pack within the rechargeable power pack has failed based on a difference between the measured capacity change quantity and the expected capacity change quantity. A charging current parameter is modified in response to the determining that the at least one component power pack has failed.

  • Publication number: 20120143541
    Abstract: Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.

  • Publication number: 20110207478
    Abstract: The present invention discloses a location based MMS generating system and method thereof. The generating system previously stores multimedia contents, each of which is related to a corresponding location. When a user's MMS request is triggered, a location service request is sent to LoCation service (LCS) server of the 3G telecommunication network to obtain the user's location. Then the multimedia contents related to the user's location are extracted and further packaged to a MMS format. The MMS generating system sends the MMS to the user. Therefore, the user may immediately receive the useful MMS.

  • Patent number: 7618481
    Abstract: A core unit of a dehumidifier comprises two towers and an upper and a lower air valve. The two towers are mounted in parallel between the upper and lower air valves and respectively filled with a drying agent. Two control valves are respectively connected to the corresponding tower through the lower air valve. When pressurized air flows into the lower air valve, the lower air valve determines that the air go to one of the two towers linked to the other tower by an equalizing slot, causing a difference in air pressure between the two towers. When the air pressure of the two towers is equal, the lower air valve changes the tower to receive the pressurized air and allows the drying agent in the other tower to dry out. Therefore, the two towers generate dry air alternately whilst reducing manufacturing costs.
