    Abstract: A capacitive proximity detector for use in a connected portable device such as a telephone, laptop or tablet, in which the capacity seen by the sensor electrode is compared with four thresholds: a proximity threshold, set lower than the other, to generate a general proximity flag, and a body detection threshold set higher than the other arranged to generate a body detection flag that indicates that the object in proximity is a part of a human body. Two object detection thresholds in the region between the proximity threshold and the body threshold define a region in which the detector can decide whether the object in proximity is an inanimate object, based on the time variation of the capacity.

    Abstract: Methods and apparatus for reducing voice call drop rate are disclosed. Existing devices do not account for the added burden of background services on voice calls. Specifically, multi-RAB scenarios (e.g., a voice call and background services) can experience significant reduction in call quality. Accordingly, in one exemplary embodiment, background services that are not time-critical and/or application-critical can be suspended while a voice call is in progress. By suspending background traffic during a call, the device can avoid unnecessary multi-RAB voice call operation, which significantly improves overall network operation and user experience.

In one or more embodiments, a host device is configured to implement a SAR mitigation algorithm to maintain compliance with regulatory requirements. The SAR mitigation algorithm may be configured to control radio frequency transmissions (e.g., output levels) for one or more antennas of the host device based at least in part upon an arrangement of an accessory device relative to the host device. By so doing, the SAR mitigation algorithm accounts for adverse influences that accessory devices may have upon radio frequency (RF) emissions from the antennas in some arrangements. The SAR mitigation algorithm may be further configured to account for user presence indications along with accessory device arrangements and adapt transmission power levels accordingly.

    Abstract: Mobile devices may minimize the radiation exposure to users by controlling the distance between the user, specifically the groin area, and the mobile device to a minimum distance. The reduction in exposure is realized due to the operation of the Inverse Square Rule on electromagnetic signal from the mobile device recognizing there is a steep fall off of signal strength resultant from increased distance between the head of the user and the source of the signal. Embodiments alert the user to a mobile device in the users pocket is in a transmission mode and thus should be removed from the users pocket to maintain operational distance between the user and the device to reduce signal absorption of the users reproductive organs. Enabled mobile devices detect the transmission mode and the acceleration of the device in determining whether to alert the user. Embodiments influence the user to maintain a minimum distance via alerts, interruptions and warnings.

  • Patent number: 8880132
    Abstract: A mobile terminal that can prevent radiation performance deterioration of an antenna is provided. The mobile terminal includes a circuit board in which an antenna and one or more key buttons are mounted, a housing mounted on the antenna and the circuit board, and a case for enclosing a periphery of the one or more key buttons and having a plurality of openings according to the quantity of the key buttons, wherein an antenna adjacent opening among the plurality of openings is extended through a slot toward an edge of the case to embody a loop antenna. Therefore, radiation deterioration of an antenna due to a case can be prevented. In addition, production costs can be minimized, and a desired external appearance of the mobile terminal is not compromised.

The reduction in exposure is realized due to the operation of the Inverse Square Rule on electromagnetic signal from the mobile device recognizing there is a steep fall off of signal strength resultant from increased distance between the head of the user and the source of the signal. Embodiments increase and maintain operational distance between the user and the broadcast device to reduce signal absorption, while maintaining sound quality and volume. Embodiments enforce the operational distance with physical barriers preventing the distance from being reduced. Embodiments described herein also allow for the retraction of the physical barrier for storage or portage.
