1. An electrical system, comprising:
- a plurality of electrical devices coupled to a power supply line;
wherein at least a first of the electrical devices has a signal-generating circuit that generates a signal indicative of power demand or use by the first device,wherein at least a second of the electrical devices includes an activation or startup circuit directly responsive to the generated signal indicative of power demand or use by the first device,wherein the activation or startup circuit regulates or controls power use by the second device according to the signal indicative of power demand or use by the first device, andwherein the activation or startup circuit prevents or delays startup or activation or a high-power operation mode of the second device while the signal indicative of power demand or use by the first device is at or above a threshold value.

Abstract
An electrical system having a plurality of devices is supplied with power by a common power supply line. One of the devices has a circuit that slows or delays device startup or activation in response to a signal indicative of power demand, draw or use by another of the plurality of devices supplied with power by the common power supply line.
