A swimming pool monitoring system using a plurality of sensor systems to detect the presence of objects within a defined perimeter of the swimming pool prior to the objects reaching the edge of the pool. The objects may be people or animals. The sensor systems may include a ranging sensor, an audio sensor, an olfactory sensor and a video imaging sensor. The sensors are monitored by a computer system that has stored data for objects authorized to be within the pool perimeter. The system provides an alert or alarm upon detection of an unauthorized or unknown object in the monitored perimeter by comparing detected objects to the stored data. The system can determine the distance of the object from the pool edge and provide an adjustable alarm as the objects nears the pool edge. The system uses facial identification and voice identification to detect authorized objects and distinguish between unauthorized and unknown objects in order to establish a level of alert or alarm that can be communicated via loudspeaker, text message or email. The system can accept updated data from any sensor for adding additional authorized or unauthorized object identification data to a system database.

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.

In an aspect, a processing apparatus receives detection signaling indicating a field incursion in a detection field of a LIDAR device mounted to a marine vessel and oriented to detect objects within a free space alongside the marine vessel. The processing apparatus applies plausibility testing to the field incursion, including determining whether parameters derived from the detection signaling are characteristic of a human body falling from the marine vessel through the detection field. The processing apparatus outputs signaling indicating a person overboard event to an alarm or control system onboard the marine vessel, in response to the field incursion passing the plausibility testing.

A safety device, and more particularly a device or system of devices for detecting dangerous situations such as the act of drowning of an individual in a body of water or a child that suddenly goes missing or otherwise inactive in a defined area, and issuing a warning to others that the potential dangerous situation is taking place so that the individual can be rescued.

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

Real-time detection and alerting for swimming pool safety includes obtaining signals from sensor devices installed in a swimming pool area having a swimming pool, ascertaining, based on the obtained signals, that an individual has entered the swimming pool and identifying, based on the obtained signals, characteristics of the individual who has entered the swimming pool, determining whether to raise an alert about the individual having entered the swimming pool, the determining being based at least in part on location of one or more other individuals relative to the swimming pool area and on checking pre-configured parameters for alerting, and performing processing based on the determining whether to raise an alert.

A system and method for monitoring a spatial position of a mobile transmitter is provided. In particular, the mobile transmitter may be attached to or included in an object of interest. By analyzing the signal strengths of radio frequency signals emitted by the transmitter, a spatial position of the mobile transmitter can be determined, and it is possible to detect whether or not the spatial position of the mobile transmitter is outside an allowable area. By applying the monitoring of the spatial position to a radio frequency system on a vessel, a reliable man-over-board detection can be achieved.
