TLDR
In this paper, the authors present a safety system for an automatic swimming pool cover having a cover and a cover drive for extending and retracting the cover, the safety system having at least one sensor for detecting the presence of a heat generating body in the pool and for generating a signal in response thereto; and a controller receiving said signal and activating a safety protocol in response to the at least sensor detecting the present body.Abstract:

Patent
Pool solar power generator
TL;DR: A swimming pool solar power generator can convert sunlight incident on the solar cells to electricity and transmit the electricity for use at a location external to the swimming pool as discussed by the authors. But the solar cell module can include solar cells and be submerged under water held by a swimming pool.

Rfid-based methods and systems to enhance personal safety
TL;DR: In this paper, personal safety of one or more users may be enhanced through the use of RFID tags carried by the users, based on data including the skill levels of the users.
Patent
Network support for swimming pool monitoring and control
TL;DR: In this article, a controllable system is represented as a swimming pool, and the control center applies the control data to the swimming pool in order to change the control parameters.
Patent
Pool alarm system
TL;DR: A pool alarm system for alerting when an intruder such as a child has entered a pool filled with water is described in this article, where a warning assembly is provided for warning an individual in a vicinity of the pool that the sensor has been activated.
Patent
Pool Cover Systems and Control Systems for Operating Mechanized Pool Cover Systems
TL;DR: In this article, a mechanized pool cover actuator is attached to a carriage, and the carriage is connected to a pool cover, which is configured to selectively drive the carriage to facilitate movement of the pool cover with respect to a swimming pool between a covering position and a non-covering position.

Patent
Swimming pool safety alarm
TL;DR: In this article, an infrared light emitter forms a beam of infrared (IR) light directed onto a set of mirrors or reflecting surfaces arranged to form a closed path about a swimming pool and spaced above the pool deck a sufficient amount so as to be intercepted by anyone who might walk through it.
Patent
Swimming pool cover assembly
TL;DR: A swimming pool cover assembly is adapted to be operated by hand by a single person as discussed by the authors, for extending a cover sheet over a swimming pool or for retracting the cover cover.
Patent
Garage door status indicating system
TL;DR: In this article, the authors present a system which will activate an alarm when a garage door is opened, using a transmitter unit and a receiver unit attached in proximity to the garage door.
Patent
Passive infrared/acoustic pool security system
TL;DR: In this paper, a pool security system incorporating a passive infrared element and an underwater acoustic element was proposed, where the passive infrared detection element generates a thin infrared layer which overlays the entire water surface area of the pool.
