Canes

There should be Swiss army knife canes. A cane should have a picker-upper, and a place to put a flask, a knife, pepper spray, a derringer, or a flashlight. The tip needs to be rubber.

• Multi-Functional Foldable LED Walking Cane, which is just an adjustable height folding cane with an LED.

• Grabber Cane, which is just what I was thinking of.

• Helping Hand Crane, another pickerupper one.

• stun gun cane

Walking Stick/Machete

Has anyone heard of a combined walking stick (with a point at the end for support on dirt slopes) and machete (for cutting weeds and small branches)?

Multi-Tools

• The MTP-6 tactical pen, with flashlight, pen, bottle opener, sort of wrench and screwdriver. COuld add a scissors.

QR COdes

Improve on them for business cards. Maybe just a frame. Maybe spirals. Patent the software. THere is opensource Python QR code code available in the Pyzbar library. Talk with cellphone companies.

Neckties

• Different sizes
• Way to put markers on them for easein tying.

Electronics

Car Radios

• Improve the speed of digital controls by not downloading anything but the address number (103.7) and the sound, so it can get to be as fast as analog.
• Add rough surfaces to all car control knobs, so you can tell if you've got the right one by touch. I hope this is done for aircraft controls already.

Earbuds and Hearing Aids

• A watch battery with a transmitter, for hearing aids and earbuds—easy things to lose. A bug, in fact, that can be turned on remotely maybe.

Microphone Speakers

Currently I think there exist portable speakers that can hooked up to microphones by wire or wirelessly. These should be made so they can be carried on one's body, in a backpack or a breastpack under clothes, or in a jacket (perhaps with holes for the sound to come through).

• Another way to do it is to broadcast a Bluetooth or other signal that can be received by a phone. Then each person in the audience with a phone can bring it out.

• Still another way to do it would be to have a bluetooth signal going to portable speakers carried by friends of the speaker who sit in various location amidst the other members of the audience.

Mouses

• Elastic inside and on the side and on top for putting a mouse in.
• Similar Stylus elastics.

Safes

Safes and fireproof boxes ought to have a radio signal emitter inside that is triggered by the heat of a fire. Perhaps one heated by motion would also be good, that can be turned off after you have finished moving the safe to where you want it, using a simple code.
