JK Lasers Set to Showcase Latest Products at Laser World of Photonics 2011

Posted: 31 Mar 2011 08:22 AM PDT

System 5000 amongst products on display

As a global specialist in the manufacture of industrial laser solutions, JK Lasers (part of the GSI Group) will be participating in the 2011 Laser World of Photonics exhibition in Munich, Germany.

During the event, due to be held at the Neue Messe München from 23-26 May 2011, JK Lasers will showcase a number of their newest products including a 1kW Fiber Laser, 500W Fiber Laser and the JK System 5000.

The JK System 5000 is a flexible workstation that can be integrated with lasers from the JK Fiber and Nd:YAG ranges. With a variety of customisable options including linear and rotary axes, process tools and scan heads, and proprietary software closely coupling motion and laser control, it provides a highly versatile solution for many industrial cutting, welding and drilling applications.

A 400W modulated, air-cooled JK Fiber Laser will be integrated into the system, to demonstrate a combined metal cutting and welding operation on a single part, made from a material that is typically used for industrial applications.

This mid-power, air-cooled Fiber Laser is suited to a wide variety of industrial manufacturing and precision applications. It can be used with a selection of JK processing heads and combines single mode fiber beam delivery, high efficiency and patented processing technologies, without requiring a cooling water supply for operation.

Whilst at the exhibition, JK Lasers also plan to launch a new addition to the JK Fiber Laser range. The new JK500FL will enable manufacturers to process a range of materials with high accuracy, at a quicker rate.

Similarly to the other products in the JK FL range, the 500W Fiber Laser will require minimal maintenance and will be supplied in a rack-mounted format, providing enhanced efficiency in the workplace.

Visitors interested in any of JK Lasers' Nd:YAG Lasers, Fiber Lasers or associated products are invited to visit the JK Lasers stand to discuss their requirements with the Sales team. JK Lasers can be found at booth # C1.466 from 23-26 May 2011.

In corporate world there is obvious scenario of reporting to more than one bosses.It is really a difficult to handle such situation where employee needs to report two or more by nature of work or any other depending situation.
What if you are put in same kind of situation where you need to report more than one Bosses about your work. How would you handle such cases. Will that be difficult or easy going thing..

Your take please?

BBG-ULD-1350-PLUS-COMBO-MONTHLY Vs. BBG-ULD-1350-COMBO-MONTHLY

Posted: 30 Mar 2011 10:13 PM PDT

I'm totally pissed off because of BSNL's IDIOTS - who're totally clueless about their own system. I requested for plan update to BBG-ULD-1350-COMBO-MONTHLY which provides 4Mbps speed up to 20 GB and 512 Kbps beyond the limit.

Now, on BSNL Selfcare portal, I see that they changed my plan to - BBG-ULD-1350-PLUS-COMBO-MONTHLY.

I'm not aware of the difference between these two plans "with and without PLUS". Can someone help in clearing out the confusion?

Converting Gas Turbines

Hi

I was wondering - if say you have a gas turbine that is used in a power station (e.g 50MW capacity) and has been running for say 10 years by burning diesel, can it then be used to run on natural gas? If so what modifications are required ?

Thanks

Car Safety Graduation Project

Posted: 30 Mar 2011 01:32 PM PDT

Hey CE. I'm new to the site but I've read through multiple posts and it's refreshing to find engineers helping each other out like this. I mostly see pricks here where I am.

Anyway I was ranting off topic. My Graduation Project supervisor wants me and the rest of my "team" to develop a vehicle safety system to reduce casualties during frontal impacts at high speeds.

Thing is, that's all he said. We've worked on it for a while so far and here are a couple of directions we have:

1) Pre-Brake the car using Magnetic or regenerative brakes when the car detects an imminent collision.

2) Extend an additional bumper connected to aluminum foam rods to partially absorb some of the energy generated during the collision.

Any other suggestions or improvements?

Oh yeah he also wants us to use a theory of innovation called "TRIZ 40" to create the product. I find it rather.... unappealing to me since it's quite vague in its solutions.

how to develop a compound cylinders......please help

Problem with KST-TX01 & KST-RX806

Posted: 30 Mar 2011 08:47 AM PDT

Hello Everyone,

I have been trying to transmit my serial data from the PIC18f4520 to my transmitter and then from my receive another PIC18f4520 will interprete the data and display it on the monitor screen.

For now, feeding the serial data from one PIC to another works with hardwire connection. the problem now is that when send wirelessly, the received data is not consistant or corrupted or sometimes nothing. Anyone has a complete circuit diagram of any filtered and amplified RF module?

Thank you so much!! =)

RaOne Movie Trailer Review

Posted: 30 Mar 2011 03:21 AM PDT

Ra.One is Bollywood superstar Shah Rukh Khan's next movie all set to release by end of the year. The movie trailer has recently been released in which SRK is shown performing awesome stunts. Watch the trailer -



Looking at the trailer, I'm bit confused whether Indian audience will accept SRK has their new super hero. It's been said that the production house used Hollywood talent for the special effects used in this movie. However, the special effects could have been more smoother - like those in movie Matrix.

SRK plays the role of G.One, who'll probably save the Earth from destruction. Looking forward to your reviews and opinions about the movie trailer.

Car Parking Counter Up To 99 Slots

Posted: 28 Mar 2011 04:09 AM PDT

hello every one.. i need some help and ideas here.. i have a project to make "car parking counter" for up to 99 slots.. the idea in its simplest form is to have a sensor in each parking slot, and two 7 segments displays common for all the slots.. so when a car enters the slot, the counter starts counting, and the display shows the number (01) which means that there is 1 full slot, and the rest are available..
i have the counters circuit but i need to konw how to conect it with the senser, to perform the wanted task??
