A safety system includes a sleeve fitted within a pool's suction line at its inlet. The sleeve terminates with a plate that resides within the suction line. The plate has holes formed therethrough. A housing defining distinct channels is fitted in the sleeve so that the distinct channels lie within the sleeve. Each of the distinct channels has a first opening on one end thereof and a second opening on another end thereof. The second openings reside in the sleeve. The first openings are in fluid communication with the water in the pool, and are distributed around a periphery of an area of the housing that prevents coverage of all the first openings when a human interacts therewith. A first sensor is coupled to the sleeve to sense pressure therein, and a second pressure sensor is coupled to the plate to sense pressure in one of the plates' holes.

1. A safety system placed at the inlet of a pool's suction line for controlling water flowing from the pool into the suction line, comprising: a sleeve adapted to fit within the pool's suction line at the suction line's inlet, said sleeve being open at a first end thereof that is approximately aligned with the suction line's inlet, said sleeve terminating at a second end thereof with a plate adapted to reside within the suction line, said plate having a plurality of holes formed therethrough;a housing defining a plurality of distinct channels therein, said housing fitted in said sleeve wherein said distinct channels lie within said sleeve, each of said distinct channels having a first opening on one end thereof and a second opening on another end thereof wherein a plurality of first openings and a plurality of second openings are defined, each of said second openings residing in said sleeve, each of said distinct channels being at least approximately three feet in length, wherein each of said distinct channels traverses a nonlinear path;each of said first openings adapted to be in fluid communication with the water in the pool, said first openings distributed around a periphery of an area of said housing that prevents coverage of all said first openings when a human interacts therewith;a first pressure sensor coupled to said sleeve and adapted to sense pressure in said sleeve; anda second pressure sensor coupled to said plate and adapted to sense pressure in one of said holes. 2. A safety system as in claim 1, wherein said housing has a central longitudinal axis, and wherein each of said first openings faces substantially radially outward from said central longitudinal axis. 3. A safety system as in claim 1, wherein said area is defined on top of said housing. 4. A safety system as in claim 3, further comprising topographic features defined on said top of said housing. 5. A safety system as in claim 1, further comprising: a first signal line coupled to said first pressure sensor; anda second signal line coupled to said second pressure sensor. 6. A safety system placed at the inlet of a pool's suction line for controlling water flowing from the pool into the suction line, comprising: a sleeve adapted to fit within the pool's suction line at the suction line's inlet, said sleeve being open at a first end thereof that is approximately aligned with the suction line's inlet, said sleeve terminating at a second end thereof with a plate adapted to reside within the suction line, said plate having a plurality of holes formed therethrough;a housing defining a plurality of distinct channels therein, said housing fitted in said sleeve wherein said distinct channels lie within said sleeve, each of said distinct channels having a first opening on one end thereof and a second opening on another end thereof wherein a plurality of first openings and a plurality of second openings are defined, each of said second openings residing in said sleeve, each of said distinct channels being at least approximately three feet in length and traversing a nonlinear path;each of said first openings adapted to be in fluid communication with the water in the pool, said first openings distributed around a periphery of a top area of said housing that prevents coverage of all said first openings when a human interacts therewith, said top area defining an undulating surface;a first pressure sensor coupled to said sleeve and adapted to sense pressure in said sleeve; anda second pressure sensor coupled to said plate and adapted to sense pressure in one of said holes. 7. A safety system as in claim 6, wherein said housing has a central longitudinal axis, and wherein each of said first openings faces substantially radially outward from said central longitudinal axis. 8. A safety system as in claim 6, further comprising: a first signal line coupled to said first pressure sensor; anda second signal line coupled to said second pressure sensor. 9. A safety system placed at the inlet of a pool's suction line for controlling water flowing from the pool into the suction line, comprising: a sleeve adapted to fit within the pool's suction line at the suction line's inlet, said sleeve being open at a first end thereof that is approximately aligned with the suction line's inlet, said sleeve terminating at a second end thereof with a plate adapted to reside within the suction line, said plate having a plurality of holes formed therethrough;an annular flange integrated with said first end of said sleeve and adapted to engage the suction line's inlet when said sleeve is fitted within the suction line;a housing defining a plurality of distinct channels therein, said housing fitted in said sleeve wherein said distinct channels lie within said sleeve, each of said distinct channels having a first opening on one end thereof and a second opening on another end thereof wherein a plurality of first openings and a plurality of second openings are defined, each of said second openings residing in said sleeve, each of said distinct channels being at least approximately three feet in length, wherein each of said distinct channels traverses a nonlinear path;each of said first openings adapted to be in fluid communication with the water in the pool, said first openings distributed around a periphery of a top area of said housing that prevents coverage of all said first openings when a human interacts therewith;a first pressure sensor coupled to said sleeve and adapted to sense pressure in said sleeve; anda second pressure sensor coupled to said plate and adapted to sense pressure in one of said holes. 10. A safety system as in claim 9, wherein said housing has a central longitudinal axis, and wherein each of said first openings faces substantially radially outward from said central longitudinal axis. 11. A safety system as in claim 9, further comprising topographic features defined on at least a portion of said top area of said housing. 12. A safety system as in claim 9, further comprising: a first signal line coupled to said first pressure sensor; anda second signal line coupled to said second pressure sensor.
