Abstract:
A method and apparatus for indicating the status of an ancillary embedded system in an electronic device. In one exemplary embodiment, the method includes starting an initialization process of a high-level embedded system in the electronic device. The method further includes determining the status of the ancillary embedded system. The method further includes generating display information for the status of the ancillary embedded system. The method further includes storing the display information in a manner retrievable by the high-level embedded system. The method further includes reading the stored set of display information and displaying an indication of the status on a user display prior to completion of the high-level embedded system's initialization process. The method further includes periodically updating the stored set of display information by the ancillary embedded system to provide a real-time indication of status.
Abstract:
A method is provided. The method includes enabling voice activated switch (VOX) mode on a communication device. The method further includes enabling a wake word detector on the communication device. The method also includes monitoring for voice activity using a voice activity detector (VAD). The method additionally includes detecting voice activity using the VAD, wherein detecting voice activity further includes: storing the voice activity in a buffer, determining, using the wake word detector, the presence or absence of a wake word in the voice activity, monitoring for and subsequently processing a voice command based on the determination of the presence of the wake word in the voice activity, and initiating a transmit operation, on the communication device, of the voice activity stored in the buffer based on the absence of the wake word in the voice activity.
Abstract:
Methods and devices for connecting an accessory device to a connector port of a mobile communication device and automatically detecting an operational mode of the connector port are provided. The method includes implementing a USB Type-C device detection at an electronic processor of the mobile communication device and monitoring a first and second pin of the connector port for pull-up and pull-down signals from a connected accessory. The method also includes interrupting the USB Type-C device detection when a pull-down signal is detected and determining whether an accessory signal is detected at a third pin of the connector port. The method also includes implementing a LMR accessory detection when the accessory signal is detected and completing the USB Type-C device detection when the accessory signal is not detected.
Abstract:
A method and apparatus for pairing devices is provided herein. During operation, an initial orientation of the two devices is determined. If the initial orientation of the two devices match a predetermined orientation offset from each other, then after a period of time, the orientation of the devices is again determined. If a final orientation of the two devices match a second predetermined orientation offset (e.g., devices are aligned), and both devices have rotated, then the two devices are paired.
Abstract:
A system and method to select boot configuration utilizes a processor, a near field communication (NFC) module coupled to the processor, and a near field communication (NFC) tag proximately located to the NFC module. The NFC tag operates as a system configuration tag to configure boot mode of the processor.
Abstract:
A communication system (100) formed of a radio management system (104) interoperates with a radio management codeplug database (106) and a confusability analyzer (108) for the creation and storage of voice recognition target strings for uploading to one or more land mobile portable radios (110) prior to field-deployment. Once the radios are deployed to the field, unrecognized voice command entries are determined, stored locally at the portable radio, and uploaded to cloud based storage (122). Analysis of the cloud based data is performed through a voice control analytics engine (124) to detect patterns associated with the unrecognized voice commands. The unrecognized voice command pattern is processed though a resolution action engine (126) to generate one or more resolution actions for the pattern.
Abstract:
A device, system and method for installing encrypted data are provided. A device includes a processor comprising: immutable memory storing preconfigured trust anchor data; and a module storing preconfigured non-exportable data. The processor is configured to: receive an encrypted common protection key, encrypted using a manufacturing protection key, and an encrypted distribution private key, encrypted using a common protection key; obtain the manufacturing protection key using the preconfigured trust anchor data and the preconfigured non-exportable data; decrypt the encrypted common protection key using the manufacturing protection key to obtain the common protection key; decrypt the encrypted distribution private key using the common protection key to obtain a distribution private key; receive an encrypted data package including image-at-rest data encrypted with an image-at-rest key, the encrypted data package including encryption data for obtaining the image-at-rest key using the distribution private key; and install the encrypted data package at the memory.
Abstract:
A system, apparatus, and method are provided for integrating a virtual assistant (VA) subsystem (114) with a repeater (102) of a communication system (100). A conventional repeater (102) containing repeater receiver (108), a repeater controller (110), and a repeater transmitter (112) communicate with a plurality of radios (120, 130). The repeater controller (110) places the repeater (102) into a repeater mode or a virtual assistant mode based on a squelch code associated with an incoming radio signal. The system provides virtual assistant operation, prioritization of mission critical calls, interrupt, and privacy on a single conventional channel. The incorporation of the virtual assistant into a conventional repeater system has been advantageously achieved without the use of additional infrastructure or additional licensed channels.
Abstract:
Systems and methods for validating the operation of a transducer and an audio signal path to the transducer. An example method includes switching, with an audio switch, the audio signal path between an audio power amplifier and an analog-to-digital converter. The method includes routing an audio signal received from the transducer to the analog-to-digital converter when the audio power amplifier is not enabled. The method includes, upon receiving a button signal, processing, with an electronic processor, a digital version of the audio signal received from the analog-to-digital converter to generate a sample. The method includes comparing the sample to a reference audio sample. The method includes generating an alert when the sample does not match the reference audio sample.
Abstract:
An electronic device includes a memory configured to store a lab certificate, a code authentication certificate and the executable code. The electronic device also includes a processor associated with a unique device identifier. For a first operational condition of the plurality of operational conditions, the processor is configured to: retrieve the code authentication certificate associated with the executable code; determine that a valid lab certificate is present in the memory; authenticate the code authentication certificate by determining that the code authentication certificate is signed with a private developer key and that the signature is valid; and execute the executable code on the electronic device responsive to determining that the lab certificate is valid and authenticating the code authentication certificate.
