Abstract
Display units with automated power governing features and related systems and methods are disclosed. A control subsystem is in electronic communication with a power subsystem electrically connected to an electronic display, temperature sensors, and a thermal management subsystem for the display unit. The control subsystem includes at least one governor which monitors external power supply and internal power demand, and where either of the external power supply or internal demand exceeds respective predetermined thresholds, commands reduction to power levels of the electronic display.
Claims20
A display unit with automated power governing features, said display unit comprising:
- one or more electronic displays;
- a power subsystem electrically connected to the one or more electronic displays;
- one or more temperature sensors;
- a thermal management subsystem;
- and
- a control subsystem in electronic communication with the power subsystem, the one or more temperature sensors, and the thermal management subsystem, where the control subsystem comprises at least one of:
- an alternating current (AC) governor and a direct current (DC) governor, wherein said control subsystem comprises one or more electronic storage devices with software instructions, which when executed, configure one or more processors to:
- where the AC governor is provided:
- monitor AC power draw by way of the power subsystem;
- and
- where the AC power draw exceeds a current draw predetermined threshold, reduce, by way of the power subsystem and within a first time period, power levels of the one or more electronic displays;
- where the DC governor is provided:
- monitor DC power demand by way of the power subsystem;
- and
- where the DC power demand exceeds a power demand predetermined threshold, reduce, by way of the power subsystem and within a second time period, power levels of the one or more electronic displays, where said second time period is longer than the first time period.
A display unit with automated power governing features, said display unit comprising:
- electricity consuming components comprising:
- electronic displays;
- temperature sensors;
- and
- a thermal management subsystem;
- a power subsystem electrically interposed between an external utility power supply and the electricity consuming components, said power subsystem comprising:
- circuit breakers;
- and
- a control subsystem comprising at least one of:
- an alternating current (AC) governor and a direct current (DC) governor, wherein said control subsystem comprises one or more electronic storage devices with software instructions, which when executed, configure one or more processors to:
- where the AC governor is provided:
- monitor AC power draw by way of the power subsystem;
- and
- where the AC power draw exceeds a current draw predetermined threshold, reduce, by way of the power subsystem and within a first time period, power levels of the one or more electronic displays;
- where the DC governor is provided:
- monitor DC power demand by way of the power subsystem;
- and
- where the DC power demand exceeds a power demand predetermined threshold, reduce, by way of the power subsystem and within a second time period which is longer than the first time period, power levels of the one or more electronic displays.
A method of operating a display unit using automated power governing features, said method comprising:
- providing the display unit, said display unit comprising:
- one or more electronic displays;
- a power subsystem electrically connected to the one or more electronic displays;
- one or more temperature sensors;
- a thermal management subsystem;
- and
- a control subsystem in electronic communication with the power subsystem, the one or more temperature sensors, and the thermal management subsystem, where the control subsystem comprises at least one of:
- an alternating current (AC) governor and a direct current (DC) governor:
- where the AC governor is provided, by way of the power subsystem and the control subsystem:
- monitoring AC power draw;
- and
- once the AC power draw exceeds a current draw predetermined threshold, reducing, within a first time period, power levels of the one or more electronic displays;
- where the DC governor is provided, by way of the power subsystem and the control subsystem:
- monitoring DC power demand;
- and
- once the DC power demand exceeds a power demand predetermined threshold, reducing, within a second time period which is longer than the first time period, power levels of the one or more electronic displays.
