US Patent:

6493885, Dec 17, 2002

Filed:

May 11, 2002

Appl. No.:

10/143446

Inventors:

Gregory Perrier - Dix Hills NY 11746

International Classification:

E04H 400

US Classification:

4504

Abstract:

A swimming pool rescue apparatus includes a safety pool bottom substrate, having a periphery made of a buoyant material and at least one non-peripheral portion is buoyant. The buoyant material is urged into a fixed position at a bottom of the pool by a retaining member. A lifting mechanism raises and lowers the safety pool bottom substrate. The lifting mechanism communicates with a detection signal device detecting the presence of a person under water in the pool for a predetermined period of time. The electronic signal device has a trigger engaging the lifting mechanism to release the buoyant material from a fixed position at the bottom of the pool to a further position at an upper area above the water level of the pool.

Appl. No.:

09/872031

Inventors:

Gregory Perrier - Dix Hills NY, US

International Classification:

G06K009/00

US Classification:

382100, 382165, 348155

Abstract:

A system substitutes digitized camera images for human vision, in determining the presence or absence of rip tides among sea water wave patterns at a public swimming beach. Computer analysis of these images involves image pre-filtering that enhances the telltale signs of rip tides, before the digital data is processed for classification as NORMAL or RIP TIDE. The classification itself can proceed along by expert systems which mimic the manner in which a human observer performs the detection; or by building a neural network, that determines its own classification criteria for identifying rip tides.

Appl. No.:

12/843035

Inventors:

Gregory Perrier - Dix Hills NY, US
John V. Mizzi - Poughkeepsie NY, US

International Classification:

E04H 4/00

US Classification:

4504

Abstract:

Apparatus usable with a safety swimming pool incorporating a buoyant submersed rescue floor is described. In one instance, a winch coupling a gear motor to a cable drum via an electrically disengageable clutch is used as a device to re-deploy the buoyant floor to the bottom after a rescue. In another instance a solar powered dedicated power supply is used to power the trigger/sensor subsystem. In yet another instance an electro-mechanical circuit for sensing and triggering a rescue episode is described.
