Abstract: A method and apparatus for limiting the effect of interfering transmission on a Global Positioning System (GPS) receiver is disclosed. A first mode of operation of the GPS receiver is provided wherein the AGC of the receiver is operated in a linear state. A second mode of operation of the GPS receiver is provided wherein the AGC of the receiver is operated in a non-linear state. A first signal is provided indicating a presence of a jamming signal. In response to the first signal the GPS receiver is switched from the first mode of operation to the second mode of operation.

Abstract: A publication system, method and apparatus simplifies end-to-end planning, building and printing of publications. The present invention allows a publication's audience and other third parties to submit content while allowing producers to collaboratively manipulate, proof and print the publication. The present invention provides in part a planning and budgeting tool that assists the producers in the initial stages of publication. The present invention can further provide a tool for custom publication development and loyalty marketing. In one embodiment, the invention can accept advertisement submissions electronically, and can afford advertisers the opportunity to receive exposure to potential consumers electronically during production.
