A monitoring system with one or more wearable devices and an alert station. The wearable device comprises sensors to detect conditions of the wearer and to transmit signals to the alert station. The alert station is configured to declare an emergency upon the occurrence of various events.

A vessel includes a body that floats in water. One or more thrusters and sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether an obstacle or a dangerous condition is present in the water; control the thrusters to avoid the obstacle, and output a warning when the dangerous condition is present in the water. The collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices.

A battery powered do-it-yourself (DIY) swimming pool sensor and alarm unit that is removably mounted in a floating assembly. The sensor monitors movement in the pool and around the pool deck and provides remote video alerts to designated cell phones as well as a localized audible and visual alarm when motion is detected. It has an above waterline camera and a below waterline camera that provides a video feed for further remote investigation. It utilizes a float stabilizing means to ensure the floating assembly is not capsized by large waves or wind. It cannot be defeated because of its floating location, and can be simply installed and set up by the average homeowner. Optionally, it has sensors that monitor the pool water's chemistry and provides the results to an owner's cell phone or to a remote chemical dispensing unit located at the pool.

The present invention disclose an occupancy detection device and related system and method for detecting presence of at least one person at or near a table or in a swimming pool with at least one sensor indicating an occupancy status locally with at least one light source and communicating it to at least one mobile device by means of at least one wireless communication method. The occupancy detection device, with the use of at least one sensor, at least one additional status is communicated to at least one mobile device. A plurality of occupancy detectors can be connected in a mesh or a star network and communicate to at least one mobile device by a wireless communication method or combinations of a wired and a wireless communication methods.

A search and rescue drone system includes a buoyant body member, a frame attached to the buoyant body member for carrying a motor and propeller, and an electronic array including a camera, GPS, an EPIRB radio distress beacon, and a transmitter/receiver for remote control flying the drone and communicating with an operator. A laser guidance system may provide coordinates for landing near a swimmer in distress. The search and rescue drone may also be programmed to simply fly to the location of an electronic wearable device, like a bracelet, that is worn by a man overboard. In another embodiment, the search and rescue drone includes pivoting motor mounts, so that it can take off and land vertically with propellers rotating in a horizontal plane, and then the propellers may pivot to rotate in a vertical plane for propulsion across water similar to a fan boat with rescued people aboard.
