patents; draw water from air, measure how much water you drink and be kind to the fish you catch.
Many people don\'t like to drink tap water because it tastes strange or contains impurities.
But bottled water can be an expensive option.
To address these inconveniences, Wayne Conrad has obtained a patent for a portable water dispenser that can collect moisture in the air.
The dispenser operates by electricity, so it cannot be used to collect water when crossing the desert. But Mr.
Conrad from Hampton, California
, Treat it as a replacement for storing bottled water, or pay for large bottled water and replace it frequently --volume coolers.
He designed a unit with a water storage tank in the lower half of the unit and an air handling unit in the upper part.
First, the fan in the upper half sucks in the air.
Then water is extracted using one of the two methods.
The dispenser can use a refrigeration pipe containing compressed gas.
In this design, when the air is in contact with the pipe, the low temperature causes the water to condense on the pipe.
The second method is to use desiccant, sponge-
Like a moisturizer that absorbs moisture from the atmosphere.
The desiccant is placed directly in the flow path of the fan so that it can absorb moisture from the air.
Once the desiccant is full, the fan will turn off.
The desiccant is then heated to concentrate the water it contains.
Once the water is concentrated, it will be collected and filtered whether the unit is refrigerated or desiccant.
The filter is designed to capture any hair, dust or other particles that are sucked into the fan with air.
Water is purified after filtration.
In his patent
Conrad wrote, \"the purifier is best
Chemicals like ultraviolet radiation or ozone.
Finally, the water is stored in the tank so that thirsty people can push the tap to fill the glass. Mr.
Conrad patented 6,251,172
Even with healthy water sources, drinking the recommended eight cups a day is a challenge for many people.
Michael Howell knows how much water he drank during the day, or just how easy it is to forget to drink more water after a few drinks.
Therefore, he applied for a patent for drinking glass, which records the number of glasses that have been consumed, the time between each service and the amount of liquid consumed throughout the day.

The patented glass has some lines, just like the lines on the measuring cup, to show the amount of water it contains.
On its basis is a programmable display, timer and LCD display.
Displays can be set to reflect the number of drunk glasses and the time interval between them.
In his patent
Costa lives in Tequesta, Florida.
A \"timer\" is written that can set a predetermined time interval, such as one, two, or four hours, etc. , providing users with a way to measure the speed of their liquid intake.
\"When a person has more water ready, he can set the timer to turn off.
The lights on the display will then flash and the buzzer or bell will ring.
After each cup, the person can record the amount of consumption and start the timer again for the next Cup.
He got a patent no. 6,252,494.
Sports fishermen who do not retain their catches may now be more likely to recover by half
Before throwing the dead fish in the water
AD David Margulis, inventor of Fort Washington.
When he wrote in the patent, he realized that many fish needed help \"recovering from being caught.
So he designed a container full of oxygen.
Revive their rich liquid.
\"Part of the fishing movement needs to struggle with the fish,\" he said. Margulis wrote.
\"When the fish is caught, it is usually because it is exhausted and can no longer resist the line. \'\'Worn-
He said that out-of-town fish will also suffer \"lack of oxygen and damage caused by hooks or hooks \".
His recovery vessel is equipped with a probe inserted into the fish mouth and a valve that compresses or pressurizes oxygen
A rich fluid is released.
This liquid may contain nitrogen or salt water, and even antibiotics for hook wounds.
The fisherman would turn the valve manually and give his fish a dose of oxygen. Mr.
The probe can have tips of different sizes for different types of fish, says Margulis.
He was granted patent No. 6,250,253.
