 A new design of very  low power  LED lightbulb and wireless sensor computer  for aiding  dementia care and Alzheimer's  patients. The SenseBulb has novel non-contact sensors to detect incidents in the home, e,g, a door left open or somebody fallen in the bathroom. A text message is  sent to a mobile phone. SenseBulb is also useful for security systems in the home and office.  Sensebulb can recognise gestures, e.g. waving a hand at a bulb can indicate "help" and the bulb with respond with a message to a mobile phone.

SMS Messages from Sensebulb's GSM modem to iPhone.

Alerts takes typically  only 15 seconds to detected and then be received by a remote mobile phone under experimental conditions. Any mobile phone can be used to receive messages. This technology, SenseDirect,  developed by Williams of Girton Labs allows wireless sensors to be used with mobile phones. There is no dependency on Microsoft PCs, emails or personal computers. All that is required is a SenseBulb, and mobile phone with PAYG contract, £10/month or 3p/message with your own phone. Setup is done using an SMS message from your mobile phone, no pc required.  SMS messages can also be sent to landline phones, using text to speech conversion to provide a voicemail message.  SenseBulb tested  on Vodafone, Orange, O2 networks,  Dual Band GSM 900 and GSM 1800.
