Shout It Loud

Looking through the upcoming patents this morning I have noticed a new patent that has been filed for a new toilet flushing system, whereas the current toilets use a level measurement for controlling water the new toilets will try to see how much urine is in the toilet and flush it in that way. All I can say is what is the point? I dont have any problems with the toilet myself nor do I know anyone that has experienced problems. Instead of inventing solutions to problems that do not exist we should concentrate more on the problems that do.
