In some aspects, a portable electronic device having a slidable upper housing and rear housing movable between an open position and a closed position, and a gain adjustment module. The gain adjustment module reduces the RF energy produced by the portable electronic device when the device is in the open position to ensure that the portable electronic device complies with Hearing Aid Compatibility (HAC) standards.

Electronic device including automatic gain adjustment for hearing aid compatibility

A mobile wireless communications device may include a housing, an antenna carried by the housing, and a circuit board carried by the housing. The mobile wireless communications device may also include a power amplifier carried by the circuit board, an antenna switch carried by the circuit board and configured to selectively couple the power amplifier to the antenna, a first radio frequency (RF) shield covering the power amplifier and the antenna switch, and a second RF shield within the first RF shield and covering the antenna switch.

Mobile wireless communications device with RF shield and related methods

A mobile wireless communications device may include a portable housing, at least one antenna carried by the portable housing, and at least one capacitive proximity sensor carried by the portable housing and configured to sense proximity of a human user adjacent thereto. The mobile wireless communications device may also include a wireless transmitter carried by the portable housing and coupled to the at least one antenna, and a controller carried by the portable housing and coupled to the wireless transmitter and the at least one capacitive proximity sensor. The controller may be configured to cooperate with the wireless transmitter to adjust transmitted power output from the at least one antenna based upon the at least one capacitive proximity sensor.

Mobile wireless communications device with proximity based transmitted power control and related methods

A method () in a multi-transmitter mobile device () can include transmitting () a signal in a first mode causing an interrupting signal to a transmission in a second mode, receiving () commands to increase power in the second mode as a result of the interrupting signal, and circumventing () the commands to increase power in the second mode when transmitting the signal in the first mode interrupts the signal in the second mode. The method can circumvent commands to increase power by alternating () a power control bit up and down and masking a true bit coming from a base station to the multi-transmitter mobile device. In another alternative, the method can circumvent by storing () a power control setting prior to the interrupting signal with a stored value, waiting for a removal of the interrupting signal, and overwriting a calculated power control setting with the stored value.

Method and apparatus for multi-transmitter power control

Within a communication device, a method of managing a plurality of modems can include determining a first measure of transmission power for a first modem (), wherein the first measure of transmission power is a running total of transmission power for the first modem over a predetermined time period, and determining a second measure of transmission power for a second modem (), wherein the second measure of transmission power is a running total of transmission power for the second modem over the predetermined time period. If a sum of the first measure of transmission power and the second measure of transmission power exceeds a threshold during the predetermined time period, at least one predetermined action can be performed ().

Monitoring multiple modem transmission in a communication device

A GPS receiver circuit () for reducing insertion loss. The receiver circuit () includes a switch () for diverting input signals between a filtered pathway () and a short circuit pathway () to an amplifier (). The amplifier () output feeds an automatic gain controller () that senses a noise level in the output of the amplifier () and adjusts a gain of the amplifier () in response to the noise level. The receiver circuit () also includes a threshold detector () with an input coupled to the output of the automatic gain controller () and an output coupled to the switch () for selecting between the filtered pathway () and the short circuit pathway (), thereby removing the filter () from the signal path if not needed.

Dynamic pre-selector for a GPS receiver

A mobile communication device () contains a local wireless controller () for operating with a remote audio processor (). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (), a baseband processor () of the mobile communication device notifies an application processor () with a high priority dispatch notification (). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.
