Hydractive Suspension: Technology and Operation
Hydractive Suspension
Hydractive Suspension is an enhanced version of hydropneumatic suspension; it is a type of computer-controlled suspension.
Proceedings of the Suspension
Variation of elastic elements is achieved by having a third sphere that can be connected or disconnected from the other two. The connection or disconnection of the additional sphere to the other two for each axis is controlled by the stiffness regulator, one per axle.
- Soft Setting: The weight is distributed across all three spheres.

Laser Cleaning for Optical Drives
For maintaining a reading recorder, perform these functions:
1. Laser Cleaning
To remove the recorder reading from the cabinet:
- Remove the 8 screws (4 on each side).
- Remove the data bus and its voltage cable.
- Open the hole cover to mechanically remove the lid.
- Once the lid is open, take out the keypad by pressing it with a screwdriver and removing any obstacles.
- Remove the 4 screws on the bottom.
- Clean the laser with a cotton swab slightly
Understanding Mechanical and Electrical Systems: Levers, Transmissions, and Electronics
Types of Levers
First Class Lever: Fulcrum between the load and the effort (R, PA, F).
Second Class Lever: Load between the fulcrum and the effort (PA, R, F).
Third Class Lever: Effort between the fulcrum and the load (PA, F, R).
Mechanical Transmissions
Screw Gear
Used to transmit movement, typically at a 90° angle. It has a single tooth-shaped screw engaging with a toothed wheel. Each rotation of the screw advances the wheel by one tooth. Characteristics include transmitting motion through right angles,

Levers
A lever is a rigid bar that is supported by a fulcrum.
Formula: F · d = R · r
Lever Classes
- Class 1: The fulcrum is between the effort applied and the resistance. The effect of the effort applied can be multiplied or reduced.
- Class 2: The resistance is between the fulcrum and the effort applied. The effect of the effort applied is always multiplied.
- Class 3: The effort applied is between the fulcrum and the resistance. The effect of the effort applied is always reduced.

Basic Logic Gates, Circuits, and Semiconductor Fundamentals
Basic Logic Gates
Logic gates are the fundamental building blocks of digital circuits. They perform specific logical operations on input signals, typically represented as binary values (0 or 1).
Key Logic Gates:
- AND: Outputs 1 only when all inputs are 1.
- OR: Outputs 1 when any input is 1.
- NOT (Inverter): Inverts the input (0 becomes 1, and 1 becomes 0).
- NAND: Negation of AND (outputs 0 only when all inputs are 1).
- NOR: Negation of OR (outputs 1 only when all inputs are 0).
- XOR (Exclusive OR): Outputs 1
