Classic model used for deriving the equations of a mass spring damper model. The mass-spring-damper model consists of discrete mass nodes distributed throughout an object and interconnected via a network of springs and dampers. This model is well-suited for modelling object with complex material properties such as nonlinearity and viscoelasticity.
There are two types of yaw damper: the series yaw damper and the parallel yaw damper. [16] The actuator of a parallel yaw damper will move the rudder independently of the pilot's rudder pedals while the actuator of a series yaw damper is clutched to the rudder control quadrant, and will result in pedal movement when the rudder moves.
This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. In order to ...
An electronically variable damper uses a radial damper with hydraulic fluid that flows freely at low speeds, allowing easy turning, while restricting flow at higher speeds when more damping is necessary, as determined by the ECM (Electronic Control Module). A prime example of this is HPSD (Honda Progressive Steering Damper) All dampers use what ...
A less common type of dashpot is an eddy current damper, which uses a large magnet inside a tube constructed of a non-magnetic but conducting material (such as aluminium or copper). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. A common use of the eddy current damper is in balance scales.
The typical work-flow of an automatic border control system (eGate) [1] Automated border control systems (ABC) or eGates are automated self-service barriers which use data stored in a chip in biometric passports along with a photo or fingerprint taken at the time of entering the eGates to verify the passport holder's identity.
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).

The second passive system orients the satellite along Earth's magnetic field thanks to a magnet. [15] These purely passive attitude control systems have limited pointing accuracy, because the spacecraft will oscillate around energy minima. This drawback is overcome by adding damper, which can be hysteretic materials or a viscous damper.
