    Abstract: Techniques are disclosed for scene analysis including the use of acoustic imaging and computer audio vision processes for monitoring applications. In some embodiments, an acoustic image device is utilized with a microphone array, image sensor, acoustic image controller, and a controller. In some cases, the controller analyzes at least a portion of the spatial spectrum within the acoustic image data to detect sound variations by identifying regions of pixels having intensities exceeding a particular threshold. In addition, the controller can detect two or more co-occurring sound events based on the relative distance between pixels with intensities exceeding the threshold. The resulting data fusion of image pixel data, audio sample data, and acoustic image data can be analyzed using computer audio vision, sound/voice recognition, and acoustic signature techniques to recognize/identify audio and visual features associated with the event and to empirically or theoretically determine one or more conditions causing each event.

    Abstract: In various embodiments, an IoT device may provide selective reporting of collected data measurements. The IoT device may report the data via a network connection to an aggregator device. The IoT device may detect when the network connection has been interrupted, during which messages containing measurements may be cached. Later, when the network connection has been restored, the IoT device may “replay” the cached messages. The IoT device may selectively report cached messages based on an entropy analysis which may detect which measurements exhibit a higher entropy. The entropy analysis may determine which measurements show a higher rate of change or which have a value outside of a set of thresholds. The IoT device may select measurements based on a history of measurements obtained by the IoT device. Other embodiments may be described and/or claimed.

    Abstract: Methods, apparatus, systems and articles of manufacture to perform remote monitoring are disclosed. Some example methods include adjusting an image capture rate at which an image sensor captures images based on a difference image containing differences between a first image of a first set of objects and a second image of a second set of objects. Example methods also include reducing a file size of the difference image using an edge detection technique and prioritizing one or more of a set of frames based on an amount of information contained in the frames. The frames are subdivisions of the image. In further example methods, the first image is taken at a first time and the second image is taken at a second, later time, and the method includes subtracting the first image from the second image to generate the difference image.

    Abstract: Technologies for managing network traffic through heterogeneous fog network segments of a fog network include a fog node deployed in a fog network segment. The fog node is configured to receive a fog frame that includes control instructions. The fog node is further configured to perform a route selection action to identify a preferred target fog node based on the control instructions, perform action(s) based on the control instructions and network characteristic(s) of the fog network segment relative to corresponding network characteristic(s) of the different fog network segment, and generate updated control instructions based on at least one network characteristic of the different fog network segment. Additionally, the fog node is configured to replace the original control instructions of the received fog frame with the updated control instructions and transmit the received fog frame with the updated control instructions to the preferred target fog node. Other embodiments are described and claimed.
