Abstract: A communications system, method and computer program product, including, transmitting in a terrestrial analog broadcast channel digital information common to users within a broadcast coverage area and digital information unique to users within the broadcast coverage area. The system, method and computer program product further include partitioning the terrestrial analog broadcast channel into a common information portion and a unique information portion, digitally modulating, within the common information portion, information common to the users within the broadcast coverage area, digitally modulating, within the unique information portion, information unique to the users within the broadcast coverage area, and transmitting the modulated common and unique information within the coverage area. The communications system, method and computer program product advantageously allows for delivery of TV program information and user specific data over existing 6 MHz terrestrial broadcast channels.

Abstract: The present invention is directed towards a necktie assembly having a separate simulated knot assembly and necktie blade. The simulated knot assembly includes a frustum that has a necktie passageway therethrough. The necktie blade has a front apron with a proximal section and a distal section. A neckband extends from the proximal section of the front apron. In use, the necktie blade passes through the necktie passageway in the frustum, and attaches to a portion of the simulated knot assembly. Because the simulated knot assembly and necktie blade are separate pieces, stylish combinations of simulated knot assemblies and necktie blades can be worn.

Abstract: A method and system for correcting errors introduced by a non-linear amplifying device to an input signal inputted to the device. A Look-Up Table (LUT) stores error correction values indexed against input signal amplitude values and input signal frequency values. The amplitude and frequency of an input signal to be inputted to the non-linear amplifying device are measured, and stored error correction values corresponding to the measured amplitude and frequency are retrieved from the LUT and used to modify the input signal accordingly.
