Abstract: An artificial neural network-based method for selecting a surface type of an object is suitable for selecting a plurality of objects. The artificial neural network-based method for selecting a surface type of an object includes performing surface type identification on a plurality of object images by using a plurality of predictive models to obtain a prediction defect rate of each of the predictive models, wherein the object images correspond to surface types of a part of the objects, and cascading the predictive models according to the respective prediction defect rates of the predictive models into an artificial neural network so as to select the remaining objects.

Abstract: A body-worn hub may detect that a first battery charge level of a first battery in a body-worn device connected to the body-worn hub via a wired connection is at or below a first battery charge level threshold. Accordingly, the body-worn hub may route power from the body-worn hub to the body-worn device via the wired connection to charge the first battery when a second battery charge level of a second battery in the body-worn hub is above a second battery charge level threshold. However, in response to the first battery of the body-worn device being charged to a third battery charge level that is above the first battery charge level threshold or the second battery charge level dropping to the second battery charge level threshold, the body-worn hub may stop routing power to the body-worn device via the wired connection.

Abstract: This disclosure describes techniques for creating a universal schema with default fields that support sensor formats of different devices. In one example, the universal schema supports substantial equivalents between data fields in different sensor formats. Further, a sensor format may be configured to support inheritance and aggregation of sensor formats in prior devices. Accordingly, the mapping of sensor formats that supports inheritance and aggregation in the universal schema may provide several advantages such as capturing a mapping of substantive equivalents between the fields in different sensor formats.

Abstract: This disclosure describes techniques for a consumer application that integrates a model-controller-view (MCV) design pattern with an event streaming platform such as an Apache Kafka™ in a network operation center (NOC) server to support NOC workspace interoperability. The MCV design pattern may include a pattern that divides an application into three main logical components (e.g., model component, controller component, and view component) to handle specific aspects of the application. In one example, the model component decouples the telemetry data streams from an event stream platform, and the controller component filters a queried set of decoupled telemetry data streams to dynamically control views to be rendered in the view component.

The heat-dissipating frame has a fixing segment and two extending segments. The extending segments connect with two ends of the fixing segment. The fixing segment connects with one side of the hard disk drive. The distance between the extending segments is greater than the thickness of the hard disk drive. At least a portion of the elastomer is disposed at the extending segments. The heat conduction layers cover the elastomer.

Abstract: This disclosure describes techniques for improving CSB platforms (or CSB applications) that manages cloud services for different clients and different environments. In one example, the CSB platforms may be interconnected and configured to act as a proxy for the cloud services. The interconnected CSB platforms may perform spontaneous updating of stored service instance addresses when a service instance is tracked to trigger a strong consistency in the interconnected CSB platforms. Alternatively, the interconnected CSB platforms may perform delayed updating of stored service instance addresses when a service instance is tracked to trigger a weak consistency in the interconnected CSB platforms. Regulation of a frequency and scope of updating may improve the use of power resources in the CSB platforms.

Abstract: A control system for a screen of a vehicle includes a global positioning system (GPS), an inertia sensor and a control circuit. The GPS detects a satellite signal from a satellite. The inertia sensor senses motion of the vehicle and correspondingly generates a motion state value. The control circuit performs one of a first determination procedure and a second determination procedure according to the state of the satellite signal. In the first determination procedure, the control circuit calculates the vehicle speed of the vehicle according to the satellite signal, and selectively locks the screen of the vehicle according to the vehicle speed. In the second determination procedure, the control circuit generates a motion signal according to the motion state value, and selectively locks the screen of the vehicle according to the motion signal. Accordingly, driving safety can still be effectively ensured even in the case of poor satellite signals.

Abstract: A locking structure, for fastening together a first case and a second case, includes: a fastening portion disposed on the first case, a hook portion movable between a locking position and a release position, and a tension spring with one end disposed at the second case and the other end disposed at the hook portion. When the hook portion moves to the locking position under an applied force, the hook portion becomes fastened to the fastening portion. After the hook portion has separated from the fastening portion under an applied force, the tension spring exerts a restoring force under which the hook portion returns to the release position. After the hook portion has separated from the fastening portion under the applied force, the tension spring pulls the hook portion back to the release position without a user's manipulation.

Abstract: A video processing engine may receive a request for a video communication session, via a network to produce a video file key that is routed to the video camera. If the video camera is communicatively connected to a Wi-Fi 6 compatible wireless access point, it routes a high-quality video file to the Network Operation Center (NOC). Alternatively, using the video key file, the video camera generates message digests and watermarks that are embedded in a video camera generated high-quality video file and a degraded quality video file. The video camera routes, via the network, the degraded quality video file to the NOC, while the high-quality video file is uploaded to the NOC later. Subsequently, a video processing engine extracts the watermarks from the message digests of the video files and compares them to ensure that the high-quality video file correlates to the degraded quality video file.

The safety detection controller is further configured to analyze the sensor data to infer the identities of third-party individuals proximate to the monitored device and determine whether those individuals pose a safety concern to the monitored individual.

Abstract: A Network Operation Center may receive video data, sensor data and third-party data for a situation that a police officer or security service personnel has been called to. Using the video data, a sentiment analysis engine may generate a sentiment data file that contains the sentiment of at least one individual involved in the situation. Using the video data, sensor data, third party data and the sentiment data file, the sentiment analysis engine may generate a safety quality value for the situation. Subsequently, the safety quality value is compared to a predetermined sentiment value to establish a safety rating and confidence interval for the situation. Furthermore, the sentiment analysis engine may generate a situational awareness file, that contains the safety rating and confidence interval, and route it to the field computing device of the officer for evaluation and implementation.
