Saving power by spoofing a device
A bridge device spoofs a wireless router on behalf of an audio/video recording and communication device (A/V device) to keep a connection with the router active. This prevents the router from dropping the connection with the A/V device.

The bridge device spoofs the A/V device by sending keepalive messages, which consumes significant power. The A/V device thereby consumes less power because the A/V device does not send keepalive messages while being spoofed by the bridge device. The A/V device and the bridge device communicate over a separate, lower power communication channel, so that the bridge can, for example, tell the A/V device when to wake up and resume communication with the router. |

Communications protocol for an electronic system
The present invention proposes assigning a common system identification code to each of a control unit and a plurality of controllable slave units, storing that system identification code in a user-inaccessible memory of those units, and allowing pairing between the control unit and each of the slave units only if the system identification code of the control unit matches that of the respective slave unit. Thus a slave unit can only act upon a control signal if the control signal comes from the control master unit which shares the system identification code, i.e. is verifiably from the same family.

It is therefore impossible for a slave unit to act on instructions from any device other than the control master unit with which it shares a system identification code, which may be alternatively referred to as a family identification code or family ID. |
