ommon motion systems use three types of control methods. They are position control, velocity control and torque control.
The majority of Newport’s motion systems use position control. This type of control moves the load from one known fixed position to another known fixed position. Feedback, or closed-loop positioning, is important for precise positioning.
Velocity control moves the load continuously for a certain time interval or moves the load from one place to another at a prescribed velocity. Newport’s systems use both encoder and tachometer feedback to regulate velocity.
Torque control measures the current applied to a motor with a known torque coefficient in order to develop a known constant torque. Newport’s motion systems do not employ this method of control.
Active suspension System of Automobiles.Mayank khare
An active suspension system,has the capability to adjust itself continuously to changing road conditions. It "artificially" extends the design parameters of the system by constantly monitoring and adjusting itself, thereby changing its character on an ongoing basis. It's schizophrenic, if you will, but with a purpose. With advanced sensors and microprocessors feeding it information all the time, its identity remains fluid, contextual, amorphous. By changing its character to respond to varying road conditions, active suspension offers superior handling, road feel, responsiveness and safety.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Old technologies revisited
1. Simple Mechanisms & Highly interesting Simple applications –
By Muralidhar Ekambaram
CEO, Adeptus Servo- Mechatronics Private Limited
2. “Certainly when I thought of the hetero structure laser, I did not intend to
invent CD Players. I could not have anticipated the tremendous impact of
fiber optic communications. The person who come up with applications
thinks differently than the scientist who lays the foundation” – Herbert
Kroemer, Nobel Laureate
The above validates the importance of Application Engineering in any
field of science
3. Applications – Four Square method of testing transmission
components – Using Mainly Mechanisms/ Transmissions and
Electromagnetic devices of yesteryears
• Mechanically close looping Power with introducing torque thru
differential transmission & a Electromagnetic torquer
• Power to simulate load conditions= only losses in the mech. Loop
i.e approx. 40% of testing power
• Static and dynamic – variable speed@variable torque tests are
possible
4. Applications – Back to back regenerative method of testing transmission
components – Present day
• Electronically close looping Power with introducing torque thru back to back
coupling of transmission elements & an Electronic regenerative Load
simulating Dynamometer
• Power to simulate load conditions= only losses in the electrical Loop and
transmissions of approx. 30% of testing power
• Static and dynamic – variable speed @ variable torque tests are possible
5. Applications – Mechanical Engineering
• Planetary screws backlash free linear movements
Works on Sun-Planetary differential transmission –
For smooth back lash free, high efficiency
rotation to linear movement conversion
7. Applications- Cycloidal transmissions
Advantages and disadvantages :
• High efficiencies
• Ultra high ratios per stage – Very low speed belt/ chain conveyors
• Compactness especially like aero space applications
• Inline Coaxial transmissions – Ease of machine designs
• Differential transmissions Like for centrifuges
• Zero backlash and high torque capacity.
• High vibration and increased wear on the exterior teeth of the cycloidal disk, as well as
component bearings due to the eccentric nature of the drive, if the cycloidal disk is not
balanced by a second disk or a counterweight.
8. Planetary gear/ Epicycloidal transmissions
Spur Planetary Helical Planetary
Applications that demand :
• High efficiencies

• Vertcal & horizontal equipment applications
• Equipment – Level control screw jacks
• Application – Critical container automatic leveling - Defence
• Prime mover – Servo motor
• Transmissions & Screw - Planetary
12. How the Decanter Process Works
• The slurry is inserted into the centrifuge through a connecting pipe and onto a conveyor.
• Utilizing an internal feed compartment, the conveyor ushers the slurry through a nozzle into
the bowl area.
• The bowl rotates at high speeds to induce gravitational forces.
• The differential speed between bowl and screw convey the solids out of centrifuge
• High speed rotation separates the solid material from the liquid in a matter of seconds.
• The conveyor delivers the solid material upwards where it is discharged through a nozzle.
• The solid material removed, the purified liquid is released from a separate output.
Applications – Horizontal Centrifuge – Decanter
13. Applications – Horizontal Centrifuge – Decanter …. Contd…
Special notes on controls
• For achieving variable differential between bowl and screw, initially Pneumatic/Eddy current
brakes were used on the second input of the differential gear box (Epicycloidal/ Cycloidal). By
varying torque through closed loop Electro- Pneumatic/ Magnetic actuations based on
speeds feed back, the differential speed used to be controlled
• In one type of Decanter, the controls used to be in Positive feed back. That is if error is
positive actuation increases and vice versa
• Subsequently, Eddy current with 4 quadrant control was used for precise control of
differential
• Presently the second input is controlled through 4 Quadrant AC drive for dead on control of
differential
14. 1.The centrifugal force required for sedimentation of the solids
2.The clarification area necessary to “capture” the solids
3.The differential speed required to transport the solids out of the decanter
4.The hydrodynamic design, which determines the exact parameters for the turbulence
5.The design of the conveyor and beach sections, which are important for efficient solids
transportation.
Applications – Horizontal Centrifuge – Decanter ……….contd……
For designing a decanter centrifuge for a particular application, very specific design
considerations to be carried out:
