ESP Services

I will perform contract work for telecommunications systems, especially IVR (Interactive Voice Response) systems, and PABX (PBX) and Call Centre integration of same.  This will be by direct negotiation in all cases, and as initial contact please send me an e-mail.  The details (including confidentiality agreements and scale of charges) are negotiable, and will not be posted here.

The range of services provided is likewise subject to discussion and negotiation - please use the contact page to send me an e-mail with a brief description of your needs.  All contact details (phone, mobile, etc.) will be provided by return e-mail.

Should you have specific requirements for a customised design or something completely new, ESP may be able to help.  I have developed many products over the years, both for individual customers and various employers, and during those periods when I was operating my own business (Elliott Sound Products).

Please Note - The availability of my time at the moment is not at all good, as I have been very busy.  The chances of a complete design for a product are poor - by all means ask, but don't expect that I will be able to help.  Projects for individuals or minor modifications to an existing published design are not possible at this time.

Some examples will show the range and diversity (customer names and specific details will not be disclosed under any circumstances).

• Audio circuits.  (Naturally) some samples are to be seen in my Projects Pages.  These say far more than I can here, and as noted, most are original designs.  This is actually a small sample, as there are still some very original ideas that I am unwilling to release to the public domain.
• Valve (Tube) Power Amplifier.  This was one of my most satisfying designs, producing a product that achieved critical acclaim and was deemed by most to be one of (if not the) best sounding amp they (the critics) had ever heard.
• Animation Camera controller.  This was a one-off development to repair an animation camera that was deemed a write off by everyone else.  It included all the necessary motor controls for a standard 6 axis (zoom, top peg bar, bottom peg bar, east-west, north-south and rotate) camera, and included movement counters, limit switching and shutter controller.
• Printed Circuit Board Design.  I have been doing this since the days of sticky pads and tapes, and have designed boards for all my own designs (including all the products described here).
• Telecommunications System Power Fail Transfer Unit.  This was designed for my employer at the time, since a new version of the telecommunications system we sold did not have this feature.  The unit was so successful that many years later when the system was replaced, it took the installers two hours to work out why the system was still taking calls - even though all the leads to the PABX were disconnected!
• Telecommunications Conference Bridge.  Another special for an employer, this unit can set up automatic (emergency) conferences with up to 64 parties - all in full duplex conference, or operate in "dial up" mode, where up to 64 parties can call a designated number and be connected to the conference.  A new feature (not available on any existing conferencing system) is the ability of any conference party to mute their channel (at the bridge, not their phone) if they are in a noisy area that would make the conference difficult for others.  This unit has resulted in sales worth a great deal of revenue for my employer.  This unit is completely analogue, and is far better than any digital system I have used.
• Multi Projector Controller.  A controller for multiple slide projectors (used for advertising in shopping centres and the like), which controlled the timing for slide changes, controlled turn-on for the lamps to prolong their life, and jamming sensors to prevent the projectors from melting (and yes, this did happen with the original simple controller).
• Multi Sector Intruder Alarm System.  This was (in its time) one of the most sophisticated alarm panels available, and had unique automatic arming and re-arming features that even now (with computer control) are not commonly available.
• Sound Recording Studios.  I have designed two recording studios, one for myself and a business partner, and another on contract.  Both were deemed very successful, and had excellent acoustics.
• Software.  I have written various software programs, most for "fun", and one commercial product as well. Various of these are in daily use (world-wide), and the only comments I get are positive.  I have also developed computer controlled telecommunications test sets and the software to drive them.
• Digital Circuits.  While I am not a fan of digital audio, I have developed many digital control systems, and several of the products above are based on logic control.

As can be expected, these are negotiable on a case by case basis.  I will generally be happy to operate on a Payment for Service basis, or a royalty based on the number of items sold and my contribution to the product.

I do not expect to have to use the services of lawyers for any contract, unless the value (to you or me) justifies this.  A sample contract is available upon request.

Absolute confidentiality is guaranteed for all negotiations, designs and products.
