Here
are some of the many successful products we have designed
|
Electronic Quality Control Instrument |
 |
This microprocessor based
instrument was to be launched in the face of established competition. By
careful consideration of the operating environment and painstaking
design, the functionality and reliability of this product was
considerably greater than competing products at virtually no extra cost.
Consequently the product has sold well and is in
use all over the world, including Japan. It has earned excellent profits
for the company, allowing them to fund further product developments.

Radiotherapy Dosimeter |
|
Using
tiny semiconductor radiation sensors, this instrument is able to
continuously measure and record the radiation dose in 5 places on the
patients body during treatment and gives clear graphical indication of
the progress of the treatment as well as raising alarms in case of
overdose.
The
instrument consists of a a battery powered data acquisition
unit which is attached to the treatment couch and an operator console
which is a small touch-screen PC running Windows CE. The console is
positioned outside the treatment cell and data and commands are sent
between the two units via a Bluetooth link.
Because
of the nature of the sensor, the data acquisition circuitry had to be
high precision and extremely stable over the temperature range. |

Automatic Inspection Machine |
 |
This product had to operate in a particularly
corrosive environment, but it was important that it continued to
function accurately 24 hours a day 365 days a year. To help achieve
this, almost all exposed parts of the machine are manufactured in
plastic. Where this was not possible, high grade stainless steels were
used.
An innovative approach was used for the cabinet. The
traditional materials were not considered suitable. Even stainless steel
would have been discoloured by the corrosive chemicals used, so the
choice was to fabricate it entirely from polypropylene sheet. As a result the machine is very
robust, and units in the field look clean and new after many years in service.
The design incorporates custom electronics,
pneumatics, stepper motor drives, fluid handling and vacuum systems, and
it is all controlled by an industrial PC.

Vending Machine Controller |
 |
In
order to facilitate this new venture in vending of high quality fresh
food we designed and manufactured a custom controller for this refrigerated vending
machine. As well as providing the user
interface and product selection on a colour LCD, the controller performs
on-line
credit card authorisation, receipt printing and control of up to 63
individual fridge doors.
It
is linked to the company's office via a GSM modem which provides remote
stock level reporting, telemetry, help phone and remote control
functions.
The
controller sends SMS messages to customers notifying arrival of
pre-ordered food, and to maintenance staff to alert them to faults such
as power
failures or refrigeration problems.
