1. TempControl (Temperature Chamber Control System)

New software and processing equipment to provide a single PC for the control of multiple environmental cabinets. For those labs who use many different types of chamber for temperature, humidity or other environmental tests we will be bringing out a software suite to control chambers from almost any manufacturer in addition to control of ancillary test equipment. Sounds interesting??? Let us know. More information

2. Time Domain Replication/RoadLoad Simulation

A technique that has eluded many for years, an effective method of controlling the replication of recorded track or time data in a continuous closed control loop. All this and an unlimited time of testing!

The new unlimited time replication software has two very important steps. Firstly, the ultra-flexible editor which allows the import of almost any raw data signal, including RPC3 and ASCII, that can then be viewed in Acceleration, Velocity, Displacement or Spectra graphs. Single point editing or signal clipping, band pass filtering, signal length selection, … are all valuable tools included in the editor. The most important fact of course is the ability to deal with very large sample files and any sample frequency.
Second step is the test phase, using highly advanced continuous update control loops and the now well known VibControl user interface, control is set up simply and applied with speed and finesse. A single file can be repeated without gaps any number of times to build up required test times.
Please download detailed information as pdf file.

3. AcousticControl (Acoustic Chamber Control System)

Fascinating stuff this, using high-level noise to test the effect of acoustically induced vibration in aerospace structures. We now have a fully digital controller using proper octave band control filters, digital sliders with position storage for repeat tests, reference control up to kHz with natural roll off to 10KHz with multi-horn control. We also include automatic drop-out of microphones going bad so no danger of bad data, if they recover we take them back in....... clever stuff. If you are in this business and want to get more out of your chamber, please let us know.
For more information about this great technique, Tom Irvine's latest newsletter, http://www.vibrationdata.com/Newsletters/May2002_NL.pdf, gives an interesting overview of acoustic chamber testing applications and practice. Tom is a well know vibration guru and his site is well worth checking out, too.

4. SmartOffice Revision 2.1

m+p international has the pleasure to announce that SmartOffice Revision 2.1 was released. SmartOffice is our open solution for noise & vibration measurement, analysis and reporting. The SmartOffice e-Reporter (the data management and reporting part of the SmartOffice) includes many new file import capabilities. The latest m+p international VibControl, Agilent SDF 5.0, Teac HDR, TDF, OROS and Standard WAV, MTS and SDRC UFF binary were added. Many other functions were implemented in Viewers, Calculator and User Programming. Besides we integrated more than 10 new modules into the SmartOffice Measure and Post-Test solutions, in the area of General, Structural, Rotating Machinery, Acoustics and Vibration Control applications.
Did you know that SmartOffice Measure directly supports the Agilent VXI hardware, including E1432 and E1434 cards? This makes from SmartOffice a most COMPLETE Noise & Vibration Solution.

5. Happy Birthday m+p international inc.!

Over ten years ago m+p international inc., Verona, New Jersey, was started to market the vibration and acoustic test systems in North America. In the last ten years the m+p international staff is proud of their reputation in the world of vibration and data acquisition thanks to the quality of their solutions, the close co-operation with the customers, strong technical relationships with their vendors and most of all reliable customer support. Many companies in aerospace, automotive, electronics and numerous other technology industries are satisfied customers and many with multiple systems.

m+p international inc. has been methodically growing and presently has offices in New Jersey, California and Michigan along with agents and representatives throughout the USA and Canada.

The employees m+p international inc. extends a special thank you to all its customers for the opportunity and trust they bestowed on them and is looking forward to working with them in the future.

6. VXI - Where Is this Highly Successful Standard Heading?

As you know our vibration and data acquisition high-end systems currently rely on the excellent performance of the Agilent VXI front-ends. This instrumentation standard has been around for while now and other emerging technologies such as NI's PXI may appear to be taking over. The following document by the VXI consortium puts the current situation into perspective and suggests there's plenty of life in the old dog yet! See http://www.tm.agilent.com/data/downloads/eng/tmo/EPSG090262.pdf

7. Agilent Choose m+p international to Upgrade their HP3565

This statement was taken from the latest Agilent DAQ newsletter, even more life in the old dog!

****' Agilent Lake Stevens Site Upgrades Vibration Control System '****

Agilent manufacturing upgraded their old 3565A LMS based Vibration Control System to a VXI based system from m+p. The new windows based VibRunner System makes it easy to support the full suite of Agilent's commercial test specs. The ability to run other internally developed matlab & VB analysis software on the same VXI hardware made the upgrade a double bonus for Agilent design Engineers. Contact your local Agilent or m+p sales office for more information: mpi@mpide.de (Europe and Asia) or sales@mpina.com (USA).
To subscribe to the Agilent DAQ newsletter send an email to agilent-data-acq@agilent.com
By the way don't forget that our VibControl family will also drive the HP3565 front-end if you would like a low cost upgrade from the LMS UNIX world to a PC based system. Just think of how much simpler reporting will be ...

8. Interesting Websites

We have found some websites that may be of interest to you or a colleague - don't keep them secret, pass them around ...
http://www.efunda.com/home.cfm
Maths, engineering data, mechanical engineering and other resources, a monster on-line reference book. A subscription is required but you get a free on-line trial - definitely worth a look.
http://assist.daps.mil/
The joys of "freedom of information" - this US site provides downloads of all standards, it's well worth getting their free registration although much is available without. Searching is a bit hit and miss unless you have document numbers but it's all there ...
http://www.access.gpo.gov/ecfr
Daily updated Electronic Code of Federal Regulations for automotive emission testing.
Of course, the best is http://www.mpide.de or http://www.mpina.com to download our VibSlideRule (the multi-function vibration calculator from m+p international) and a demo version of our SmartOffice software.

9. Dates for Your Diary
