Dialog Devices had a vision to improve the speed and availability of non-invasive assessment of Peripheral Arterial Disease, to prevent heart disease and stroke. The role of GBD was to commercialise the algorithms and early proof-of principle prototypes Dialog had developed. GBD eliminated the need for tests to be carried out by skilled Doppler Ultrasound operators, involving patients having to make expensive and time consuming hospital visits.

GBD formed a partnership with Sabre Technology, who provide electrical engineering support. Sabre built upon the circuitry developed by Dialog and sourced relevant hardware within budget. The team brought together an advisory network including Peripheral Arterial experts and primary care staff for feedback throughout the project. After proposing various form factors and interfaces, a hand-held touch-screen device was decided upon. The team quickly developed software prototypes for user testing. References were taken from user’s established relationships with mobile electronics devices.
