Abstract
After installation, a device may be asleep. A light signal device may send a message to the sleeping device to wake it up. This wake-up message may comprise the light signal device sending programmed light signals, the programmed light signals in modified morse code. An authentication part may also be included in the message. The light signal device may request an authentication message from the sleeping device.
Claims20
A signaling device for activating a sleeping device comprising:
- a light source;
- a memory;
- and
- a processor configured to:
- determine a message to be delivered to a sleeping device,
- encode the message for transmission via flashing light signal to produce an encoded message, wherein the encoded message specifies a sequence of light flashes, and
- control the light source to flash light according to the sequence of light flashes at an intensity operable to cause power to be applied to the sleeping device, whereby the sleeping device is caused to awaken and receive the encoded message.
A method performed by a signaling device for activating a sleeping device comprising:
- determining a message to be delivered to a sleeping device,
- encoding the message for transmission via flashing light signal to produce an encoded message, wherein the encoded message specifies a sequence of light flashes, and
- controlling a light source to flash light according to the sequence of light flashes at an intensity operable to cause power to be applied to the sleeping device, whereby the sleeping device is caused to awaken and receive the encoded message.
A non-transitory computer readable storage medium encoded with instructions for execution by a processor for activating a sleeping device, the non-transitory computer readable storage medium comprising:
- instructions for determining a message to be delivered to a sleeping device,
- instructions for encoding the message for transmission via flashing light signal to produce an encoded message, wherein the encoded message specifies a sequence of light flashes, and
- instructions for controlling a light source to flash light according to the sequence of light flashes at an intensity operable to cause power to be applied to the sleeping device, whereby the sleeping device is caused to awaken and receive the encoded message.
