    Abstract: Electronic devices with wireless communications capabilities are provided. The electronic device may include storage and processing circuitry, power amplifier circuitry, power supply circuitry, etc. The storage and processing circuitry may direct the power amplifier circuitry to operate using a desired gain mode, in a particular radio channel, and at a given output power level. The power supply circuitry may bias the power amplifier circuitry with a power supply voltage. The performance of the power amplifier circuitry may be characterized by an adjacent channel leakage ratio (ACLR) margin. The power consumption of the power amplifier circuitry may be characterized by a current savings ratio. A cost function may be calculated by taking the product of the ACLR margin and current savings ratio. A minimum point for each cost function curve may be determined. It is desirable to bias the power amplifier circuitry with a supply voltage corresponding to the minimum point.

    Abstract: Two or more acoustic transducers share the same acoustic port in a device. The acoustic properties—such as acoustic impedance and frequency response—of the shared acoustic port are matched to each of the two or more acoustic transducers. To accomplish acoustic impedance matching, a separate back volume is provided for each of the acoustic transducers, matched to that transducer. Frequency response matching can be accomplished by the design of the transducer itself, but also by providing an adjacent element in the acoustic system of the transducer. One transducer may serve as an element in the acoustic system of another transducer. Frequency response adjustment of an individual element may also affect acoustic impedance of the entire port-transducer system.

    Abstract: A portable handheld electronic device contains a camera lens and accelerometer to allow a user to control voicemail and call features by swiping his finger across the camera lens and/or tapping the device. Therefore, the user can comfortably input commands into the device with a single hand and without needing to move the phone away from his ear to apply these inputs. In another embodiment, the camera lens can also be used to control navigation of the display screen or a displayed document of the device. For example, if a user wishes to shift a scrollbar for a page displayed on the screen downwards to view the bottom of the page, the user should move his finger over the camera lens in an analogous downward direction.

    Abstract: A mobile electronic device has a touch sensitive screen and an accelerometer. A translator is to translate a word or phrase that is in a first human language and that is entered via a first virtual keyboard displayed on the touch sensitive screen, into a second human language. A translator is to cause the touch sensitive screen to display the translated word or phrase and a second virtual keyboard having characters in the second human language, in response to the accelerometer detecting a change in the physical orientation of the device or movement of the device. Other embodiments are also described and claimed.
