Speaker 1: have things we like to think about. Online fraud shouldn't
Speaker 1: be one of them, because with every purchase, Visa prevents, detects,

Speaker 1: Brain with today's question. Could an anti lock braking system
Speaker 1: detect a flat tire in a car? And anti lock
Speaker 1: braking system is a system that helps the driver to
Speaker 1: avoid skids during panic stops. In a car with normal brakes,
Speaker 1: all four wheels will lock and cause the card to
Speaker 1: skid if the driver jams on the brakes in a
Speaker 1: panic situation, the problems with skidding our first, the car
Speaker 1: will actually take longer to stop. In second, the driver
Speaker 1: loses all control of the vehicle, and the anti lock
Speaker 1: braking system lets a computer monitor of the wheels. If
Speaker 1: one of the wheels locks, the computer compulsed the brake
Speaker 1: on that wheel, so the wheel keep spinning a little bit.
Speaker 1: Because the wheels continue to spin, the driver can continue
Speaker 1: to control the car with the steering wheel. The computer
Speaker 1: census rotation using a rotation sensor on each wheel. If
Speaker 1: the computer were programmed correctly, and if there were a
Speaker 1: light on the dashboard, then the computer could detect a
Speaker 1: flat tire and warn you about it. What the computer
Speaker 1: could do is look at different rotational speeds For one
Speaker 1: out of the four wheels, a flat tire would spin
Speaker 1: faster than a properly inflated tire, So the computer would
Speaker 1: look for one tire spinning faster than the other three
Speaker 1: on average over the course of a period of time
Speaker 1: that it could warn the driver by activating the light
Speaker 1: on the dashboard. There are several production cars that use
Speaker 1: this technique, starting with two thousand six models. The National
Speaker 1: Highway Transportation Safety Administration requires that all cars have some
Speaker 1: kind of tire US You're monitoring system. Do you have
