Takeshiba Electric's ultrasonic urinary sensor
On the off chance that you can't actually tell yourself, Takeshiba Electric is going to start selling a little handheld device that uses ultrasound waves to measure the urine is in your bladder and then let you know whether it's time to do your business or not. We'd make a lame joke about how Japanese this is, but this way, way too weird, even for Japan. There's probably some totally legitimate medical use for this that we've never heard of. Please someone tell us this is the case.
