On November 20, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals a new invention that generally relates to using networked electronic devices like Apple iDevices and Macs as smoke detectors for your home. As part of a smart home system, Apple illustrates how future iDevices will act as smoke detectors and be able to automatically call 911 for emergency assistance. The system will be able to supply emergency services with information about how many occupants are currently in the home and in which rooms they're located in due to motion sensors embeded in Apple's mobile and stationary devices. Apple's HomeKit will be able to work with future third party dedicated forms of Fire Detectors as well so as to work in conjunction with Apple's new system. Interestingly Apple illustrates that the new system could actually be integrated into their upcoming Apple Watch or at least a future generation of it.
