Abstract: Systems and methods for improving water safety are provided. The methods include various features based on monitoring the area around a pool. Benefits are gained by applying artificial intelligence algorithms, as well as various techniques for improving processing speed and eliminating false alarms. A system for promoting water safety includes: a camera device configured to capture images in a monitored area around or above a body of water, the camera device configured for mounting to a structure outside the water; a computing device configured to process the captured images and to apply artificial intelligence for human recognition to the processed captured images; a mobile device configured to receive a notification if a human is detected in the captured images; and an extender in wireless communication with the camera device that extends a wireless network to the camera device.

Abstract: Embodiments of this application provide a method and a device for displaying a representation indicator of an object. In the method, values of representation indicators of a plurality of monitored objects at a plurality of sampling time points are determined; and image information used to display changes of the representation indicators is generated, where the image information includes the plurality of sampling time points, values of representation indicators of a plurality of objects that meet a sorting requirement at the plurality of sampling time points, and association information, and the association information is used to associate values of representation indicators that are at a same sorting position at the plurality of sampling time points, to reflect changes of the values of the representation indicators that are at the same sorting position.

Abstract: Systems and methods for improving water safety are provided. The methods include various features based on monitoring the area around a pool. Benefits are gained by applying artificial intelligence algorithms, as well as various techniques for improving processing speed and eliminating false alarms. A method for promoting water safety includes the steps of: video monitoring an area including around a body of water, and above or at a top surface of the water; detecting a presence of a human suspect in the monitored area through processing images of the video with computer implemented artificial intelligence; storing an image upon detection of the human suspect in the monitored area; processing the stored image to determine if the detection was a false alarm; and if the human suspect is determined to be a human in the monitored area, then transmitting an alert, either to a device in the area being monitored, to a mobile device, or both.

Abstract: An abnormality detection method includes displaying a target interface, where n-dimensional visualization space defined by n coordinate axes, and m data points and p target regions that are located in the n-dimensional visualization space are displayed in the target interface, each coordinate axis corresponds to one detection indicator of a detected object, location data of each data point in the n-dimensional visualization space is a data record of the detected object, the data record includes n items of data, each item of data is a value record of the one detection indicator of the detected object, the p target regions are determined by n one-dimensional data intervals, and each one-dimensional data interval is within a range of a corresponding coordinate axis; and displaying, in the target interface, that the detected object is abnormal when k data points in the m data points are located outside the target region.

Abstract: This invention discloses a method of using a cloud server to remotely detect the status of a home automation gateway of a home security and automation network. According to this invention, the home automation gateway of the home security and automation network periodically sends heartbeat packets to a cloud server. The cloud server monitors the reception of all these heartbeat packets, records relevant information contained in these heartbeat packets in a database, and updates the most recent status of the particular home automation gateway. If the cloud server has not received any heartbeat packets from the home automation gateway for more than a predetermined time period, the cloud server considers the home automation gateway currently offline and notifies the user of the home security and automation network by sending a notification message to the user's mobile device.

Abstract: This invention discloses a power saving method for battery-powered Zigbee devices. When a Zigbee device loses connection with a Zigbee network, it will search for the Zigbee network until it finds and rejoins the network. However, the Zigbee network may not be available for a sustained period of time due to a long power outage. To avoid wasting the battery power of the Zigbee device on performing too many searching operations, the Zigbee device waits for a waiting period after performing a search operation and before performing a subsequent search operation and the waiting period prior to each subsequent search incrementally increases while more subsequent searches are performed.

Abstract: This invention discloses a method implemented on a cloud server which issues a unique device serial number to be assigned to a network device (e.g., a WPAN gateway, smart home device). Among other things, the unique device serial number contains a cloud server identification portion which uniquely identifies the issuing cloud server. When the network device is powered on, a identifies the cloud server based on the cloud server identification portion of its device serial number and tries to connect with the cloud server. Upon receiving such a connection on request, the cloud server checks whether the network device's device serial number was one it issued previously. If yes, the cloud server allows the connection. Otherwise, the cloud server denies the connection.

Abstract: This invention discloses a power saving method for battery-powered Zigbee devices. Under normal circumstances, a Zigbee device keeps its RF module in sleep mode. Only when the Zigbee device receives a signal generated in response to a sensor triggering event, a user input, or a prescheduled event, would the Zigbee device wake up its RF module to communicate with a Zigbee coordinator. As such, the Zigbee device does not need to always listen to the Beacon signals periodically broadcasted by the Zigbee coordinator, therefore saving a lot of battery power.
