Abstract
An electrical system may include a processing circuit and one or more electrical components that emit thermal heat energy. The processing circuit may be configured to identify signal degradation or failure of an in-band communication channel between the electrical system and a second electrical system, identify a data message to transmit to the additional electrical system via an out-of-band communication channel, and direct the one or more electrical components to adjust an electrical workload to modulate and transmit the data message on the out-of-band communication channel as a recoverable sequence of thermal pulses.
Claims21
An electrical system comprising a processing circuit and one or more electrical components, the processing circuit configured to:
- identify signal degradation or failure of an in-band communication channel between the electrical system and a second electrical system;
- identify a data message from a pool of data messages to transmit to the second electrical system via an out-of-band communication channel;
- and
- direct the one or more electrical components to adjust an electrical workload to modulate and transmit the data message on the out-of-band communication channel as a recoverable sequence of pulses or fluctuations, wherein the data message includes an identifier indicating a type of data message from the pool of data messages.
An apparatus, comprising:
- a memory;
- and
- a first processing circuit in communication with a memory, wherein the first processing circuit is configured to:
- identify signal degradation or failure of an in-band communication channel between the first processing circuit and a second processing circuit;
- identify a data message from a pool of data messages to transmit to the second processing circuit via an out-of-band communication channel;
- and
- control an electrical workload of the first processing circuit to modulate and transmit the data message on the out-of-band communication channel as a recoverable sequence of pulses or fluctuation, wherein the data message includes an identifier indicating a type of data message from the pool of data messages.
A non-transitory computer readable memory medium storing program instructions executable by a first processing circuit to:
- identify signal degradation or failure of an in-band communication channel between the first processing circuit and a second processing circuit;
- identify a data message from a pool of data messages to transmit to the second processing circuit via an out-of-band communication channel;
- and
- control an electrical workload of the first processing circuit to modulate and transmit the data message on the out-of-band communication channel as a recoverable sequence of pulses or fluctuations, wherein the data message includes an identifier indicating a type of data message from the pool of data messages.
A method for transmitting a data message on an out-of-band communication channel, the method comprising:
- a first electrical system,
- identifying signal degradation or failure of an in-band communication channel between the first electrical system and a second electrical system;
- identifying a data message to transmit to the second electrical system via an out-of-band communication channel;
- and
- directing one or more electrical components of the first electrical system to adjust an electrical workload to modulate and transmit the data message on the out-of-band communication channel as a recoverable sequence of pulses or fluctuations.
