Overview• The Two Problems
– Protecting Loved Ones at Home– Day to Day Key Access
• The Solution• How Does It Work?• How Does the Software Work?• How Does the Hardware?• Future Plans• Conclusion• Questions?• Demo
4
Problem One Protecting Loved Ones at Home - Alzheimer or Dementia Patients
• Two million people suffering from extreme dementia in Canada alone
• They have poor judgment• They forget that they have left an
equipment turned ON, or how to operate an equipment
• There are many problems created by dementia patients, for them or people around them by misuse of dangerous equipment
5
Problem One Continue … Protecting Loved Ones at Home – Small Children
• There are many dangerous appliances at home (oven, fireplace meat grinder, etc …)
• Hard to keep children away from them
• But how do we keep patients or children safe at home?
6
Problem Two Day to Day Key Access
• Everyday you carry 5-10 keys or access cards
• They could get stolen, lost or left behind
• Temporary access for guests can be a problem
• Customized access not possible with keys
7
The Solution
• Using the VirtualKey System (also named VK)• Have appliances automatically disable when a parent or
caregiver is not around• Extremely simple to use, effective and cheap to own• The dementia patients and children will not be able to
operate dangerous appliances that are VirtualKey enabled• The VirtualKey enabled appliances only work when a
caregiver or a parent are nearby• Unlock all your doors with your cellular phone
8
• VK System has two components: VK hardware module and Cell phone software
• The hardware module can be integrated into any device or appliances such as oven, power saw, fireplace or into a power bar
• VK module can disable the appliance when a caregiver or parent is not around
• The module can be installed in any appliance• It listens for a pass code transmitted automatically from caregiver’s
cellular phone nearby, and enables itself.• It uses the existing Bluetooth protocol on the cell phone• The VK hardware installed inside appliances will automatically
enable/disable the appliance with caregiver’s proximity
How Does Virtual Key Work?
9
How Does the Hardware Work? • The VirtualKey hardware module listens for incoming Bluetooth connections from
nearby cellular phones• The wireless Bluetooth connection must be encrypted• The pass code transmitted to hardware must be valid• After all these requirements are met, the hardware will enable the appliance• After the cellular phone leaves the room where the appliance is the hardware
module will disable• The cell phone can enable the hardware when both are on the same room• The phone can be left in care givers pocket, and all the communications takes
place automatically• All the time delays for enable/disable period are adjustable

The Hardware Details• AVR ATmega32 Running at
4MHz for power consumption and using UART at 9600 bps to communicate with the Bluetooth module
• Blue Radios Bluetooth module Version 1.1, with SPP Stack
• 3.3, 5.0, 12.0 V Power supply with surge protection
• Brownout protection as well as extreme temperate capable components
• Firmware upgradeable using port JTAG
12
How Does the Software Work?
• Java based software is installed on the cellular phone
• Any Bluetooth enabled cell phone can be used
• VK software currently supports 90% of the cell phones offered today
13
• The software is programmed using J2ME language
• It can run on any java-enabled brand of phone and completely operating system independent
• JSR-82 API is needed on the cellular phones
24
Future Plans
• Testing VK where children/dementia patients are present
• Further improve the product
• Demonstrate for future funding
• Patent and commercialize
• Simple device, market should adapt quickly
25
Conclusion• VirtualKey is a cheap/effective way to control your
appliances and protect your loved ones• Even control your door locks with VK module and
your cellular phone • Cost as low as $10 a module, on a mass produced
basis• Current hardware cost for a single item is $110 (our
cost)
26
Conclusion
• What was learned:– AVR Assembly programming– AT command set– Bluetooth structure and protocol– J2ME Programming– Encryption in Java and Bluetooth
