Applicant: Shih-Hsiung Li, TaiwanPatent number: US6,181,645Publication date: 30 January 2001Title: Ultrasound Sensor for Distance Measurement
An ultrasound sensor for distance measurement is disclosed. The ultrasound sensor has a housing, a ceramic buzzer, a plurality of isolators both received in the housing and a C ring for securing the plurality of isolators in the housing. The housing has an elliptical compartment and a circular compartment defined therein. The elliptical compartment communicates with the circular compartment and both have a unique shape, which is able to limit the shape of the emitted signal by the ceramic buzzer. The limited range of the emitted signal by the ceramic buzzer covers the entire cross-section of the vehicle and will not cause a false alarm by reflection from the ground.
