Abstract: A portable communication system (100) maintains mission critical functionality. An accessory (120) and a handset (130) are tethered and interoperate such that the accessory operates as the primary controlling device and the handset operates as a secondary device. The accessory (120) contains a main applications processor (102) that handles non-mission critical functions. The accessory further contains a mission critical processor (104) for handling mission critical functions of transmit and receive audio as well as PTT and emergency. In response to a failure of the mission critical processor (104), the mission critical functions are maintained by handing over the mission critical functions to the non-controlling device in a manner transparent to the user. The handover is triggered in response to status changes of the mission critical processor or as a result of battery depletion. Audio paths are re-routed through backup paths (146b, 148) negating reliance on processors of the accessory (120).

Abstract: A method and apparatus for controlling a battery operating mode. The method includes connecting an electronic processor to a first electrical contact of a battery interface via a switch; generating, with the electronic processor, an initialization pulse for a signal demultiplexer of a battery; transmitting the initialization pulse to the signal demultiplexer; generating, with the electronic processor, a data word indicating a desired operating mode; transmitting the data word to the signal demultiplexer; generating, with the signal demultiplexer, a signal to electrically connect a first battery switch to the first electrical contact, the first battery switch selected based on the data word; receiving, with an analog to digital converter of the electrical device, a signal indicating the operating mode voltage; and verifying, with the electronic processor, a correct operating mode based on the operating mode voltage.

Abstract: A battery operated portable communication device provides converged functionality while avoiding resets to the device. Composite logic circuitry formed of at least one comparator and a logic interface controls current limiting to a primary load formed of high power land mobile radio (LMR) devices and programming to secondary loads formed of non-LMR peripherals. At least one current limit control signal is used to control current to the primary load under high current mode operations. Another control signal provides an interruption alert to a slave processor for controlled programming of the secondary loads during the high current operations of the primary load. Current to the primary load is restored while the secondary load is interrupted. Operation of secondary load processes is resumed when the primary load ceases high power operation.

Abstract: Systems (100) and methods (400) for extending battery life on a Communication Device (“CD”). The methods involve: configuring operations of CD and an accessory such that they operate in a first operational mode in which the accessory has a first functionality; and detecting the occurrence of a trigger event. The trigger event occurs when: (a) CD's power source has a State-Of-Charge (“SOC”), capacity or voltage level that is not optimal for powering the accessory, (b) a voltage level of the accessory's power source is below a lowest voltage level at which the accessory can fully operate, or (c) a power source of the accessory is sufficiently charged/re-charged such that the accessory can once again operate in the SOM. In response to the trigger event, operations of CD and accessory are re-configured such that they operate in accordance with a second operational mode in which the accessory has a second functionality.

Abstract: Methods and systems for mitigating interference between different transceivers in a portable communication device. An electronic control circuit is configured to quantify an electromagnetic isolation between a first transceiver of a portable communication and a second transceiver of the portable communication device based on a detected radio frequency power coupled to the first transceiver from radio frequency signals transmitted by the second transceiver. A mitigation action is selected from a plurality of mitigation actions based on a magnitude of the quantified electromagnetic isolation. The selected mitigation action is then applied to the second transceiver to adjust at least one radio frequency characteristic of the second transceiver.

Abstract: Systems and methods for an audio switching circuit. One system includes an audio switching circuit including a first P-channel transistor including a first source terminal, a first gate terminal, and a first drain, a second P-channel transistor including a second source terminal, a second gate terminal, and a second drain terminal, and a control circuit. The second drain terminal is coupled to the first drain terminal. The first P-channel transistor is configured to receive a first audio signal at the first drain terminal. The control circuit is configured to disconnect the first gate terminal from a ground reference, and in response to the presence of the first audio signal, cause a first voltage between the first gate terminal and the first source terminal to be approximately zero and prevent the first audio signal from passing through the first drain terminal.

Abstract: A method and circuit for mitigating RFI in an electronic device that occurs while the device is in a low power mode utilizes one or more antenna elements in the device to receive RF energy. When the RF energy is sufficiently high that it could affect signal states in the device while in the low power mode, the device transitions from the low power mode to an active mode and begins an RFI mitigation process to ensure signal states and other circuit operations in the device are not changed by the RFI.
