A passive water cooler comprising a water tank arranged for containing a volume of water, an internal heat exchanger disposed within the water tank for contact with (e.g. submersion within) said volume of water and an external heat exchanger disposed outside the water tank in thermal communication with the internal heat exchanger. The external heat exchanger and the internal heat exchanger are connected and arranged to collectively define a fluid circulation circuit configured to contain coolant fluid flowable by convection to provide said thermal communication for transferring heat therebetween. The tank comprises thermally insulating material for thermally insulating said volume of water from the environment within which the external heat exchanger resides. The external heat exchanger is arranged to be positioned higher than the internal heat exchanger to permit formation of a thermocline within the coolant fluid between the external heat exchanger and the internal heat exchanger.

A door security system and method may increase the home security for elderly people without limiting the privacy of or convenience for residents. The method comprises detecting closing of a door; keeping a first locking mechanism of said door in an open position for a first predetermined period of time after said closing; after said predetermined period of time, changing said first locking mechanism into a locked position. The re-entry time frame permits a user to re-enter without a key, immediately after realizing they forgot it. The method may further comprise recognizing motion of a person on a door of a house through a camera provided in or near the door; producing streaming footage; sending the streaming footage to a central processing server; processing the streaming footage for face recognition purpose and checking against several; and storing all data on the server.

The present invention provides a fluid injection system (11) which transitions between a maintenance mode wherein an outlet (15) is closed and no fluid is discharged through the outlet, and an operation mode, wherein the outlet is open and fluid is discharged through the outlet. The fluid injection system injects a first fluid transported in a first pipeline (21) with a second fluid, wherein there is a temperature differential between the first fluid and the second fluid. The fluid injection system comprises a holding tank (49) for storing the second fluid, a cooling means (35) to cool the second fluid, and a pump (39) for delivering the second fluid into the first pipeline. The second fluid mixes with the first fluid in the first pipeline to provide a combined third fluid having a temperature within a predetermined temperature range, wherein the third fluid is maintained within the predetermined temperature range when the fluid injection system is in either mode such that the temperature of the third fluid made available to an outlet is within the predetermined temperature range.

An emergency shower includes a column having upper and lower inlets, outer, intermediate, and inner pipes defining outer, intermediate, and inner conduits, and one or more heating coils positioned within one or more of the conduits. An instantaneous water heater can be integrated into the column of the emergency shower. The emergency shower can include a shower head and an eyewash assembly for cleaning a person after the person encounters toxic materials.

A first responder decontamination system, method, and apparatus comprising of a fluid supply in fluidic connection with a pipe further connected to a fluid dispenser, a valve for providing the fluid to the fluid dispenser from the fluid supply, a mounting bracket for adjustably mounting the fluid dispenser to a vehicle, and a pump configured to control pressure of the fluid supply. The fluid supply can be used to decontaminate first responders exiting a contaminated area.

An apparatus including an inflatable tube assembly; a shower assembly; configured to be attached to the inflatable tube assembly when the inflatable tube assembly is in an inflated state; a canopy configured to cover the inflatable tube assembly, when the inflatable tube assembly is in the inflated state; a first bottle for inflating the inflatable tube assembly; and a backpack configured to hold the inflatable tube assembly in a deflated state, simultaneously the first bottle. The apparatus may further include a second bottle; wherein the backpack is configured to hold a second bottle, simultaneously with the first bottle and the inflatable tube assembly in the deflated state; and wherein the second bottle includes a decontamination material. The apparatus may further include a third bottle, wherein the third bottle is a water bottle; and wherein the water bottle is configured to supply water to the shower assembly.

Disclosed herein are apparatuses for collecting water in a shower or bathtub enclosure. The apparatus comprises a water-resistant or waterproof panel, one or more connectors coupled or coupleable to the panel, the one or more connectors enabling the panel to be disposed within the shower or bathtub enclosure, and a receptacle coupled or coupleable to the panel, the receptacle having an opening for collecting water from a surface of the panel, the receptacle for delivering the collected water to a destination other than a drain of the shower or bathtub enclosure. The destination may be a container, a bucket, a toilet, a tank, a planter box, a plant pot, or an outdoor location such as a garden or lawn. The collected water may flow directly to the destination, or the apparatus may use a channel to deliver the collected water to the destination.

The shower head nozzle as disclosed herein includes a quick-connect coupling for selectively attaching the nozzle to a downwardly extending conduit or tube for directing tested water through a test unit and into a bucket or drain, wherein the test unit may include a flow meter for measuring real-time water flow rate and a temperature sensor for measuring real-time water temperature dispensed from the shower head, thereby reducing the testing time, more accurately determining flow-rate and water temperature, and decreasing the amount of waste water.

The disclosure extends to safety response systems, methods and devices, and more particularly, but not necessarily entirely, to a safety shower and/or safety eyewash bath or unit as well as a pre-cast shower base used in connection with a safety shower and/or eyewash bath or unit, which may be used in various industries that require such safety showers or safety eyewash equipment.

A shower nozzle assembly includes a shower nozzle, a nozzle attachment, and a bayonet connector. The shower nozzle has a water inlet opening and a water outlet part spaced from the water inlet opening, with the water outlet opening being configured to direct a flow of water out of the shower nozzle. The nozzle attachment has a through bore configured to receive the water outlet part therein. The bayonet connection is operative to secure the nozzle attachment to the shower nozzle, and includes a radial projection and a female bayonet receptor part configured to receive the radial projection therein to secure the shower nozzle to the nozzle attachment.
