The present invention relates to a wearable smart appliance in the form of a wristwatch. The appliance is designed to track a user's vital signs and send real-time alerts to a paired electronic device for remote monitoring of the user. More specifically, the appliance tracks vital signs such as heart rate, and notifies a parent or guardian if the user is in danger. The appliance also includes a water sensor that activates an alert if the sensor is underwater for a certain length of time. A GPS sensor detects the current location of the user and is included in the real-time alerts during emergencies.

A system used to monitor and control a pool using a visual light communication system is disclosed.

A detection and tracking system and method using a camera unit on a robot, or alternatively a camera mounted inside the pool overlooking the bottom of the pool, for safety monitoring for use in and around water-related environments. The robot is able to propel itself and move throughout the body of water, both on the surface and underwater, and the camera unit functions both on the surface and underwater. The robot optimizes the cleaning cycle of the body of water utilizing deep learning techniques. The robot has localization sensors and software that allow the robot to be aware of the robot's position in the pool. The camera is able to send its video feed live over the internet, the processing is performed in the cloud, and the robot sends and receives data from the cloud. The processing utilizes deep learning algorithms, including artificial neural networks, that perform video analytics.

An adjustable surf wake system enhances a wake formed by a watercraft travelling through water. The system may include a flap for deflecting water traveling past the stern of the watercraft, and/or a positioner operably connected to the flap for positioning the flap relative to a longitudinal axis of the watercraft between a neutral position and an outward position. Positioning a port flap in its extended position enhances a starboard surf wake, and positioning the starboard flap in its extended position enhances a port surf wake. A wake modifying system for modifying a wake produced by a watercraft traveling through water may include a rudder pivotally mounted to the watercraft for steering the watercraft, a fin pivotally mounted to the watercraft substantially along a centerline of the watercraft and forward the rudder, wherein the fin pivots about an upright axis to modify the wake produced by the watercraft traveling through the water, an actuator mounted within the watercraft and operably coupled to the fin for pivoting the fin relative to the centerline, and a controller mounted on the watercraft allowing an operator to control the actuator and selectively pivot the fin to a desired angle θd relative to the centerline.

A signal device for maritime distress rescue and a surveillance device for maritime distress rescue are provided. The signal device for maritime distress rescue which is carried by a user aboard a vessel may include a first communicator configured to communicate with a surveillance device for maritime distress rescue of the vessel, a first position detector configured to generate first position information of the signal device at a predetermined time interval, and a first controller configured to receive second position information of the surveillance device from the surveillance device at a predetermined time interval and determine whether the first position information is within a safe area of the vessel that is set on the basis of the second position information. Accordingly, when a distress occurs, it is possible to transmit a distress signal without operating a switch while minimizing power consumption of the signal device.

A control system for boats includes a direction control system of a propulsion unit having a directional control member, and an acceleration/deceleration control system of the propulsion unit having an acceleration/deceleration control member. The directional control member activates a directional unit that generates directional control signals, which set an orientation of the propulsion unit, and the acceleration/deceleration control member activates an acceleration/deceleration unit that generates acceleration/deceleration control signals, which set at least a number of revolutions of the propulsion unit. The control system further includes a display unit provided with a screen, and a camera having a control system that provides images of areas or zones that cannot be observed by an operator of the control system while steering the boat, so as to enable driving the acceleration/deceleration unit and/or the directional unit according to a content of those images.
