New Gadgets - Four Ideas

It is possible that some of these new gadgets already exist in an inventor's basement or garage somewhere. One or two may even be patented, but then again, maybe not. Probably most things are dreamt up ten or ten thousand times before someone actually does something with the idea. The dreaming is more fun for some of us, so feel free to do something with the following.

Magnets For Windows
These signs would be a new advertising gadget. Already, thousands of businesses use large flexible magnetic signs for their vehicles, with the company name and logo on them. However, these can only be used on metallic surfaces. To to stick to car or building windows, they need to have a similar magnet or steel mesh material that is placed on the other side of the glass, to hold them in place magnetically. This may not be a patentable product, but the first to trademark a catchy name and market them widely might do well.

Barking Dog Alarm
There are already all sorts of new home security gadgets out there, but there is room for many more. One not-so-new idea is the motion-sensors that set off an alarm. The problem with these is that a criminal may still enter the home, either intending to be in and out quickly, or to turn off the alarm. On the other hand, if the sensor triggers a realistic recording of several large dogs barking, he may hesitate to go further.

Helium Balloon Cell Phone Antenna
Often a cell phone won't work simply for the lack of elevation to get it above interfering hills and other obstacles to the signal. This new gadget would be a simple wire antenna that could be attached to any helium balloon. With light wire, the balloon might lift the antenna 50 or a 100 feet into the air to pick up that signal. A mylar balloon and a tiny canister of helium could be marketed with it too.

Kitchen Towel Gadget
My Kitchen towel gets in the way when I hang it on the refrigerator handle. However, if it had a small but strong magnet sewn into one corner, I could "hang" it anywhere on the refrigerator, or on any other steel surface.
