Device to put on a coat

Milton Keynes panel were asked if we could help a client to put on his outdoor coat. He could not move his hands to behind him, which meant putting on a coat in the normal way almost impossible.
A powered device was made which, under the control of the Client, lifts the coat up his back then releases it when the coat collar reaches shoulder height

Intravenous Pump – Alarm Monitor

A monitor for an intravenous pump audio alarm. The client needs to be alerted by a vibrating pager as she is deaf. The pump has no alarm output other than an audio signal. A system has been designed and built that can distinguish the pump alarm in relatively high ambient noise and reject other events such as knocking or tapping on the microphone sensor.

Electrification of recumbent trike for 9 year old boy

A 9 year old boy with cerebral palsy uses a recumbent trike to strengthen leg muscles, but he is not strong enough to pedal up hills. The project provides electrical assistance by modifying the trike to add a motor, battery, pedal sensor and control module. This was complicated by the larger wheel required for the motor necessitating relocating the rear brake, fitting a new brake lever with cut out switch and emergency kill switch for the electrics.

Electric bed custom hand controller

This project provided a custom replacement for the client’s electric powered bed hand control. It was delivered in two stages, the first version incorporated an existing controller into a 3D printed case and certainly worked and, although it was not optimal, it did give the client the chance to better consider the best design for his needs. The second version was designed based on his feedback and just used standard micro-switches inside.

Fly-by-wire kids tractor

Personal location tracker

The parents of a 16 year old with Down Syndrome and autism would like to give him maximum independence while ensuring his safety when he leaves the home without his carers knowing. The usual locators are unsuitable because he cannot be relied on to take one with him. A small GPS tracker was attached to his glasses (which he will always use). It sets off an alarm when he leaves home and allows his carers to locate him quickly.

Hands Up Alternative

A nine year old girl with cerebral palsy wanted to be able to attract her teacher’s attention like all the other pupils did by raising their hands.
