Non-monopolistic invention disclosures

The following are technical ideas of mine, not all of them actually implemented. They are disclosed to prevent a person or organisation hitting on the same idea later from patenting them. Both commercial and non-commercial use is welcome. Note that I have not verified that these ideas have not been discovered and patented by somebody else before me, have no means to do so and make no guarantees whatsoever that they are free from the rights of third parties. If you want to use them commercially, this remains for you to check. The disclosures have been submitted to Linux Defenders / Defensivepublications.org and as a consequence are on record as prior art.
