An agent analysis system includes a terminal product system, a remote diagnosis system (RDS), and an agent analyzer. The terminal product system is supplied with a power source and provided with a current sensor to sense the power source. The RDS is used to transmit at least one control instruction via internet for the terminal product system. They agent analyzer is used to communicate with the terminal product system and the RDS, and configured to measure and analyze the electricity use characteristics of the terminal product system to be transmitted to the RDS; and receive and convert the control instruction from the RDS via internet for the terminal product system.

A terminal product usable time management system includes a remote server and a local apparatus. The local apparatus includes a data memory storing an identifier and an encrypted usable time of the terminal product, a microprocessor used to send a start notification of a usable time management process, a product controller used to control a product load, and a wireless networking device used to communicate with the remote server to receive a new expiry date to update the usable time. The usable time management process includes: reading the encrypted usable time stored in the data memory, decrypting the encrypted usable time, decreasing the usable time per time unit, encrypting the decreased usable time, storing the encrypted and decreased usable time into the data memory, and instructing the product controller to disable some or all functions of the terminal product, if the usable time is inaccessible or decreased to zero.

An inflatable float tank for providing a therapeutic sensory deprivation session. The inflatable float tank includes opaque inflatable sidewalls including a drop-stitch material. The drop stitch material includes opposing walls with stitched threads extending at acute angles from one another. When uninflated these internal stitch structures are allowed to collapse and provide substantially foldable and pliable deflated sidewalls as opposed to substantially rigid sidewalls upon inflation. The inflatable float tank is filled with float solution including water and Epsom salt heated to skin temperature so as to provide a highly buoyant float environment with a lack of sensory stimulation. The inflatable float tank exhibiting improved insulation within the tank and ease of assembly. The inflatable float tank and assembly thereof doesn't require rigid support structures such as poles and joints. And, the inflatable float tank is substantially foldable in an uninflated state and is substantially rigid in an inflated state.

An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

A managed water system can include a first body of water contained in a vessel. The managed water system can also include at least one sensor device that measures at least one parameter associated with the first body of water. The managed water system can further include a circulation system that circulates the body of water relative to the vessel. The managed water system can also include a controller communicably coupled to the at least one sensor device and the circulation system. The controller can control the circulation system, and receive measurements of the at least one parameter made by the at least one sensor device. The controller can also evaluate the measurements using multiple algorithms, and communicate a result of evaluating the measurements.

A bypass system is provided for use with a pool water heater having a pool water heater input port configured to receive a portion of pool water, a heating system configured to heat water received by the pool water heater input port, and a pool water heater output port configured to output heated water from the heating system. The bypass system includes a pool water receiving port configured to receive pool water, a bypass line configured to divert a portion of the water from the pool, an output port configured to output the portion of pool water from the pool, a pool water heater receiving port configured to receive the heated water from the heating system, and a pool output port configured to output, to the pool, a combination of the heated water from the heating system and the portion of the water from the pool.

A water cooling and heating system for swimming pools and hot tubs for heating and/or cooling a flow of water drawn from a body of water and then returning the heated and/or cooled flow of water back to the body of water wherein the system includes an inner conduit within an outer conduit, the outer conduit having an exterior conduit surface that is exposed to solar energy from the sun whereby a portion of the solar energy absorbed by the outer conduit is transferred to and heats an outer water flow within the outer conduit and the outer water flow in the outer conduit heating an inner water flow of water in the inner conduit, the system further including at least one control valve to selectively control a flow of water to the inner and outer conduits and a bypass flow of water that is directed back toward the body of water.

Provided is an improved coupling for preventing water leakage in heating systems that include solar collector panels which incorporate plastic or rubber tubes that are connected to inlet and outlet water manifolds. The couplings are reinforced, dual durometer materials that are flexible enough to form a strong seal to any cylindrical tubes or pipes utilized in the heating system as well as rigid enough to tolerate the expansion and contraction of the coupling body during extreme conditions of use.

An inlet mixer system for a gas heater includes a housing in fluid communication with an inlet of a combustion blower, and first and second mixer inserts, each removably positionable within the housing. Each mixer insert includes a body defining a mixing chamber, an air intake, and a plurality of orifices disposed radially about the body and extending through the body, which provide respective volumetric flow rates of a fuel gas. When the first mixer insert is positioned within the housing, the inlet mixer system is configured for use with a first fuel gas, and when the second mixer insert is positioned within the housing, the inlet mixer system is configured for use with a second fuel gas.
