The Ankle Rehabilitation Machine is unique as it incorporates functional stress training with a biofeedback system which currently no machine on the market can do.

Physiotherapists can assess the level of injury, set in place a rehabilitation program and monitor patient progress. Patients use a interactive machine with structured program to aid faster rehabilitation

Production Drawings PDM

The PyraScaf mobile tower solves a serious safety issue. It eliminates the inherent danger of constructing towers that they must be physical climbed whilst they are being built.

With its patented lever arm design it allows rapid construction of the tower from the ground up to any height. This makes the PyraScaf tower safer to use, quick to set up and easy to move.

from conception to market

Bringing the PyraScaf tower to market called for the iterative analyses of specifications and performance requirements to establish the final design.

This process was aided by capitalising on R&D, field tests and collaborating with research personnel, to come up with a design that could be produced at minimum cost by existing manufacturing methods and facilities

Human Powered GeneratorIdea generation > Concept development > Testing > Manufacture

The device converts a human input of kinetic energy into an electric output.

Aimed for users of small electronics such as IPods and mobile phones.

The Human powered generator is portable and relieves the dependency on conventional power sources such as the main grid, thus giving the user a 100% Green and independent device.

Breath Monitor

The Breath Monitor is a medical device designed to monitor a patients breathing during a MRI scan. A non invasive device that uses a diaphragm around a patients chest to measure the expansion and contraction of the lungs. The pressure difference in the diaphragm is measured on Differential Pressure Transducer (DPT) and the electrical output is fed to a LED bar graph display to give a real time visual reading of the patients breathing status.
