Air brakes use compressed air to maximise braking forces. Design and Function A compressed air brake system is divided into a supply system and a control system. The supply system compresses, stores and supplies high-pressure air to the control system as well as to additional air operated auxiliary truck systems (gearbox shift control, clutch pedal air assistance servo, etc.). How airbags work The design is conceptually simple; a central "Airbag control unit"[14] (ACU) (a specific type of ECU) monitors a number of related sensors within the vehicle, including accelerometers, impact sensors, side (door) pressure sensors[15], wheel speed sensors, gyroscopes, brake pressure sensors, and seat occupancy sensors. When the requisite 'threshold' has been reached or exceeded, the airbag control unit will trigger the ignition of a gas generator propellant to rapidly inflate a nylon fabric bag

Suur osa ROPS toimimise eelduseks on tugevtatud esiklaasiraam, mis ei annas üle katuse rulludes järgi. [2] [8] 2. Passiivse ROPS süsteemi ehitus Ehituse poole pealt on enimlevinud kahte tüüpi süsteemid, Mercedese poolt kasutatud niinimetatud ,,Flip Up" süsteem ja Volvo, WV ja muude poolt kasutatav ,,Pop Up" süsteem. 2.1 ,,Flip Up" süsteem Flip up süsteemi kasutab Mercedes ja on olnud kasutusel 1986 aastast. Süsteemi juhtimiseks kastutatakse osaliselt samu andureid, mis airbag süsteemil. Osadel juhtudel jubib süsteemi airbagiaju. Põhilised andurid, mida kasutatakse, on kaldenurga andur, gravitatsiooniandur (andur mis tunnetab, kui auto muutub kaalutuks, ehk on õhus). ,,Flip Up" süsteem on üldjuhul juhitud hüdrauliliselt ja seda on võimalik manuaalselt aktiveerida juhtpaneelist. Oma ehituselt on ,,Flip Up" U kujuline tugevdatud tala. [3] Sele 2. Aktiveeritud asendis ,,Flip Up" tala [3]

This may mean that a fairly large bypass capac- itor is needed if the shaft can turn at low speeds and a resistive divider is used to provide the bias. Motion/Acceleration Sensors Sometimes you need to measure acceleration or tilt or other motion. The obvious application is airbag deployment in a car. However, there are other applications, such as sensing vibration that could indicate excessive bearing wear or an unbalanced load in a motor-driven application. Solid-state acceleration sensors use internal capacitors to measure this force (Figure 3.28). A micromachined movable beam and two fixed plates are used. The movable beam has a spring that keeps it centered between the two fixed plates when there is no acceleration. The two fixed plates are driven
