David W Best: Apparatus and method for providing a logical exclusive OR/exclusive NOR function. Rockwell International Corporation, Bruce C Lutz, Howard R Greenberg, H Fredrick Hamann, January 3, 1984: US04424460 (192 worldwide citation)

Circuits are illustrated using CMOS design techniques for incorporating N and P channel transistors into a circuit to obtain the functions of exclusive OR and exclusive NOR signal generation. This is accomplished by utilizing a given logic value signal as a control signal to pass the other input sig ...

Michael P Taylor, Jean R Oliphant: Overflow and diversion to a foreign switch. Rockwell International Corporation, V Lawrence Sewell, Howard R Greenberg, H Fredrick Hamann, August 23, 1983: US04400587 (187 worldwide citation)

A method of overflow and diversion re-routing is disclosed for use in an automatic call distributor system of the type in which an incoming call is assigned to an original gate, that is, a group of agents, but in selected circumstances the call is to be re-routed from the original gate. The ACD syst ...

Vincent R DeLong: System and method for encrypting a voice signal. Rockwell International Corporation, V Lawrence Sewell, H Fredrick Hamann, Howard R Greenberg, April 17, 1984: US04443660 (102 worldwide citation)

A system and method are disclosed for encrypting a voice signal. The input signal is filtered to provide a signal in a first path with components in a higher frequency band and a signal in a second path with components in a lower frequency band. Analog-to-digital conversion is carried out at a rate ...
