Abstract
A system and method for detecting the presence of an immobile object in an unattended container of liquid such as a bathtub or swimming pool. The system may include at least one sensor or include an array of sensors located at the bottom of the container, a remotely located controller, and an alarm signal generator. The controller is operative to process the sensor data to detect an object which has remained immobile for at least a predetermined time. The system includes an image generator to provide an attendant with a view of the area of the container at which the immobile body is located. At least one motion sensor is also provided in some embodiments. A method is also disclosed that implements the functions of the system.
Claims26
A system for detecting an immobile object in a container of liquid, the container having an accessible bottom, the system including:
- At least one sensor being configured to provide a proximity signal output indicating the presence of at least a part of an object at the bottom of the container at the said sensor location;
- a controller;
- a communication channel connecting said sensor to the controller;
- and
- an alarm signal generator,
- wherein the controller is operative to scan the proximity signal output of said sensor in a repetitive sequence and responsive to a succession of proximity signals from said sensor that are substantially non-varying over a predetermined time period to activate the alarm signal generator.
(canceled)
A method for detecting an immobile object in a container of liquid having an accessible bottom, the method including:
- positioning at least one sensor at the bottom of the container, said sensor configured to provide a proximity signal output indicating the presence of an object at the bottom of the container at the sensor location;
- transmitting the proximity signals to a controller through a communication channel, wherein the controller is operative to detect a proximity signal from said sensor indicating an object that is constant for a predetermined period of time thereby indicating that the object is immobile;
- and
- generating an alarm signal when an immobile object has been detected.
