    摘要: 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.

    摘要: A sensing system for a floating pool system for detecting and alerting a user of disturbances and detecting various levels and releasing chemicals into a liquid medium. The system comprises a controller that can comprise a wireless communication module and at least one sensor, and a receiving device can be configured to receive a signal from the wireless communication module. The controller can comprise at least one tilt sensor that is generally in an open position and closes with a waking event. The controller sends a message to the receiving device when a waking event occurs, alerting the user to a disturbance and possibly dangerous situation.

    摘要: 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.

    摘要: 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.
