Abstract
Abstract A method of coding to provide command signals simultaneously to selected devices is disclosed. Each device is assigned a different power of the same integer. Commands are then signaled to the desired devices by sending a series of pulses, the total of which is the sum of the integer raised to the power of each the devices to be commanded. Thus if devices having powers of 0 and 3 are to be commanded, and the integer is 2, 9 pulses would be sent. (2°=1, 2 3 =8, 1+8=9). Each different total will signal a unique device or a unique combination of devices.

Claim 1
Independent Claim
62 words
A method of providing a signal to one or more of a plurality of devices comprising: assigning to each device a particular power of an integer; and transmitting to said devices a series of pulses having a total equal to the sum of the integer raised to each of the powers of those devices to which a signal is to be sent.
Claim 2
Independent Claim
62 words
