The electromagnetic parking sensor (EPS) was re-invented and patented in 1992 by Mauro Del Signore. [2] Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once an obstacle is detected, the sensor continues to signal the presence of the obstacle even if the vehicle momentarily stops.

A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
The Evolve car can automatically perform parallel parking by using sensors and a computer to control steering, acceleration and braking of Volvo S60. An automatic parking system uses various methods to detect objects around the vehicle. Sensors installed on the front and rear bumpers can act as both a transmitter and a receiver.
An ultrasonic level or sensing system requires no contact with the target. For many processes in the medical, pharmaceutical, military and general industries this is an advantage over inline sensors that may contaminate the liquids inside a vessel or tube or that may be clogged by the product. Both continuous wave and pulsed systems are used.
An enhanced system, called Ultrasonic Rear Occupant Alert, also uses ultrasonic sensors. [2] If the vehicle is locked and the ultrasonic sensors on the headlining detect movement in the rear seats, the system will flash the hazards lights and sound the horn for 25 seconds, and again if the system continue to detect movement, for up to eight ...
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
Example of obstacle avoidance using sensors. One of the most common approaches to obstacle avoidance is the use of various sensors, such as ultrasonic, LiDAR, radar, sonar, and cameras. These sensors allow an autonomous machine to do a simple 3 step process: sense, think, and act.
