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 programmable signaling light source with a processor and a memory, comprising:
- a programable light source with a processor and memory operationally able to flash light at a known intensity for a known time;
- an encoder operationally able to encode a message;
- and
- executable instruction that upon execution by the processor perform the following actions:
- the encoder encoding a message comprising a message part and an authentication part, producing an encoded message;
- and
- the programable light source sending the encoded message at least twice;
- wherein the encoded message is encoded in modified morse code.
A method implemented by one or more computers with memory, one or more processors, a light source, and a transceiver, comprising:
- translating a message into modified morse code;
- the message comprising a message part and an authentication part;
- and
- repeatedly transmitting the message.
A non-transitory computer readable storage medium storing instructions for externally activating a quiescent device wherein the instructions when executed by a processor, cause the processor to perform steps including:
- translating a message into modified morse code;
- the message comprising a message part and an authentication part;
- repeatedly transmitting the message;
- wherein the modified morse code comprises signals, and the signals comprise a rising or falling edge followed by a number of time durations;
- requesting a secret message using a second transmitter;
- and
- receiving a secret message using the second transmitter;
- when the secret message is equivalent to the authentication part, resending the message.
claim 20. The non-transitory computer readable storage medium of claim 19, wherein a DOT is one time duration, a DASH is three time durations, and an END OF WORD is 9 time durations.
Dependencies are inferred from the claim text.
