    Abstract: A process of ranking internet-of-things (IoT) data based on IoT analytics services. In operation, the IoT gateway receives IoT data captured by an IoT device and transmits the IoT data to IoT analytics servers each providing a different IoT analytics service. The IoT gateway receives acknowledgments including data rankings from IoT analytics servers. Each of the acknowledgments include a respective one of the data rankings indicating an importance of the IoT data as an input to the IoT analytics service provided by a respective one of the IoT analytics servers. The IoT gateway assigns an aggregated data ranking to the IoT data based on the data rankings included in the acknowledgments received from the IoT analytics servers. The IoT gateway then transmits, to the IoT device, an electronic notification including the aggregated data ranking assigned to the IoT data.

    Abstract: Methods for detecting faults in a siren-based alert system include receiving, by a siren device from a central siren controller, an activation command. The activation command identifies a neighbor siren device that is to be activated. Audible alerts output by the neighbor siren device include a unique identifying characteristic associated with the neighbor siren device. The method includes determining that the unique identifying characteristic is not detectable by the siren device and, in response, taking corrective action. The corrective action includes the siren device sending a siren fault notification to the central siren controller indicating a failure to detect the unique identifying characteristic and may also include modifying the audible alert output by the siren device to compensate for the faulty siren device. The siren device may send a siren fault notification to the central siren controller if an unexpected audible alert, such as a potential false alarm, is detected.

    Abstract: Techniques for message acknowledgement when messaging system is unavailable are provided. A controller may receive a group text including a message that requires acknowledgement. The group text is directed to at least one controller. A message identification may be extracted from the message. The message identification may be associated with the message that requires acknowledgement. A talkgroup identifier may be computed based in part on the message identification. A radio associated with the controller may join a talkgroup that is associated with the talkgroup identifier. A floor control request may be sent via the radio on the talkgroup associated with the talkgroup identifier. The floor control request may serve as an acknowledgement of receipt of the message.

    Abstract: A method and apparatus for operating a camera is provided herein. During operation a microphone will identify an object by receiving the sound emitted by the object. Once the object has been identified, a main frequency component of the received sound is determined, and camera parameters are adjusted based on the value of the main frequency component.

    Abstract: Techniques for voice announcements over communications paths in siren systems are provided. In one aspect, a siren activation sequence including an audio identification sequence may be received at a siren alert site controller over a data communications channel of a first communications path. The audio identification sequence may be extracted from the siren activation sequence. A first combined audio signal may be received at the siren alert site controller over a voice communications channel of the first communication path. It may be determined that the first combined audio signal includes the audio identification sequence. The audio identification sequence may be extracted from the first combined audio signal to create a first audio signal. The first audio signal may be played over a siren controlled by the siren alert site controller.
