I'm thinking about getting an older beater for driving and I don't see any limitations for mileage in either lyft or uber's requirements but I've ran across a couple random posts about a 100,000 mile limit. Does anyone know if there is such a limit for either company? Thanks!
Audible sound is the sound which is between 20 Hertz to 20000 Hertz and can be heard by human beings, whereas Inaudible sound may be below 20 Hertz or above 20000 Hertz and thâ¦is can't be heard by human beings.
Subsequent inaudible commands could be issued to the activated voice assistants and execute tasks such as making a phone call, visiting a website or controlling smart home devices. The video below demonstrates what is called a DolphinAttack. An iPhone is first shown to make a call using audible voice commands issued to Siri. Then the iPhone is shown to be locked and an inaudible voice command in an ultrasonic range is issued to Siri which then recognizes the command and again makes a call. This would be without the knowledge of device owner if they werenât looking at the screen.
