Title: Innovations by David E Campbell
Introduction
David E Campbell is an accomplished inventor based in Mountain View, CA. He has made significant contributions to the field of utility meter technology. With a total of 3 patents, Campbell has developed innovative protocols that enhance the efficiency and security of utility meter communications.
Latest Patents
One of his latest patents is the Bi-directional Protocol. This protocol allows for utility meter interrogation with a data write portion that includes assembling a password transmission sequence. This sequence has a synchronization string and a message that includes identification indicia for a selected utility meter. The password is used to activate a specific data access level within the utility meter. The transmission is wirelessly sent twice to confirm the password sequence. Additionally, a command transmission sequence is assembled to store data in a memory location of the utility meter corresponding to the activated data access level. This command sequence is also transmitted wirelessly two times for confirmation.
Another notable patent is the Uni-directional Protocol. This invention provides a unidirectional method for communicating data from multiple utility meters. The meters are designed to monitor and measure various utility parameters, including gas, water, and electricity. The information is wirelessly downloaded to a meter reading device. The protocol includes a synchronization pattern followed by the desired information, which is transmitted in a sequence that is immediately repeated for validation. A bit is toggled during the retransmission for added security.
