Appeal No. 1999-0001
Application No. 08/613,828
Claim 1 is illustrative of the claimed invention, and it reads as follows:
1. A system for switching electrical power to a plurality of loads on a plurality
of hot AC lines, the system comprising:
a plurality of switch control devices, each containing a power
switching element, each switch control device being physically located on a hot AC line extending
between a source and a load, the power switching element switching power delivered by
the corresponding hot AC line to a load attached to the switch control device;
a control switch input on each switch control device;
a control interface, and;
at least one signal branch extending from the control interface, a plurality of
switch control devices being attached to each signal branch so that control signals can be
communicated between the control interface and the switch control devices, the control interface
polling selected ones of the switch control devices, and transmitting
output signals to other switch control
devices so that the power switching element in one switch control device can be
controlled by control switch inputs on another selected switch control device.
The references relied on by the examiner are:
Miller et al. (Miller) 4,484,258 Nov. 20, 1984
Cotie et al. (Cotie) 4,667,193 May 19, 1987
