| Chelsfield consultants can design hardware solutions to fill
many diverse requirements from very
small (but sometimes essential) interfaces through to complete turn-key systems or sub systems.

Our electronics design and programming experience ranges from
PLC's and 8 bit legacy systems such as the 8085 and 1802 through to
PIC controllers, 8052, i960, x86, and numerous other
processors. For volume, we would seek to apply
whatever VLSI techniques might be
appropriate such as FPGA's or DSP
devices and if the situation demands it,
we would consider the implementation of full custom
ASICS ... more |
|
| So whether the task is to
assist you with your new product or
to provide you with that essential bit
of kit that's needed in the office or
factory, Chelsfield can create
custom solutions, many components of
which are likely to have already been
tried and tested. |

| A
"stand-alone" instrument is one
that is self contained and that does not
rely on external systems to operate.
Nowadays such instruments are usually
controlled by connection to a
computer, typically a PC or laptop, but
many use built-in displays and control
mechanisms. |

used to show important stability data of
large floating vessels. It was
designed and built by Chelsfield
Consultants and is based on mathematical
models produced by the Santa-Fe
Laboratories, University College London. |

Applications |

Chelsfield has a history of applying electro-optic
techniques in a wide range different situations.
This does not just mean the occasional use of fiber
transmission or in the application of
"standard"
optical detectors. Chelsfield Consultants have led
numerous instrumentation projects which have
had optical systems as part
of their core functionality. |
|
| Instruments and
systems developed by us have included
advanced laser scanning and data acquisition systems
right down to inexpensive plastic components
intended for volume production. |

| The picture shows red,
green and blue light produced from an
argon-ion laser in a high resolution
real-time projection system. The laser
is running in TEM (00) with a mixture of
the 488 and 514 nm lines used for green
and optically-separated 457 used for
blue. Red is generated by
splitting the 514 line out to pump a dye
laser. Sophisticated electro-optic
feedback systems are used to control the
very high speed mechanical scanning
assembly. |
|
| Derivatives of the
experimental apparatus shown here were
used by numerous clients including the
BBC Research, Marconi, NASA and
Schlumberger. |

 |
| We develop
network communication modules that
enable you to both monitor and control
virtually any process or system from
within your plant. Not only that,
with some additional software, you will
be able to do this from anywhere in the
world via an internet connection. |

| This rugged terminal was
specified by the South African PTT. The
design was a collaborative venture
between third parties who designed the
case and display electronics and Chelsfield
who undertook the terminal electronics
and firmware. Manufactured in
South Africa by Telephone Manufacturers
PTY, the device needed to gain both South
African, US and UK approvals. |

| Meet
Dr. David Evans of the
Gastro-Intestinal Science
Research Unit at the Royal
London Hospital. He is
modeling an instrument,
designed by Chelsfield
Consultants, that records
small-bowel motility
function. |
|
| Chelsfield
also designed and built the
specialist interface that
allows the clinician to
upload data to a PC,
together with the analysis
software. |
|
| Following
papers written by Evans and
his colleagues, these robust
portable instruments have
been sold to nearly 100
research centers and
institutes around the
world. These include
Iowa State University
Hospital, the Karolinska
Institute, the Mayo Clinic
and Edinborough Royal
Infirmary. |

| Getting
balanced sound coverage in stadiums or
large auditoriums can be tricky, to say
the least. Engineers can monitor
line level and performance but this
doesn't always convey accurate detail
about the quality of sound actually
experienced by the listener for a wide
variety of reasons. |
|
| The Rovamix was
designed by Chelsfield to enable mixing
desks to be remotely controlled via
radio link. The unit is outside
the audio path and can address
individual channels. Almost all controls
of the unit are programmable with
channel ID and function. |

Chelsfield
has met a very wide range of standards and approvals
for clients and countries and for different
industrial sectors. Telecommunications: for direct
connection to public switched networks: BT, (BABT
and the European, US and African equivalents). Type approval for components, and systems has
also been gained from many commercial organisations
such as Marconi, GEC, and Northern Telecom.
Quality, safety
and other performance standards achieved for general
industrial-control equipment of our design also
includes sections of the generic ISO9000 (BS-5750). We have also worked to industry
specific British Standards on documentation such as 3939, 4058, 6238
together with a variety of commercial
client-produced quality design, manufacturing, and
safety standards.
In the aviation
industry, flight deck test equipment (of Chelsfield
design with sub-contract manufacture) has gained
various FAA, CAA, and IAM/DOD approvals. For the
medical sector, other than BS safety standards,
performance and type approval has been gained from
NHS procurement, FDA, and many NGO's around the
world.
