The use of outdoor wireless access points for services such as Internet access is gaining popularity. At the same time, there is an opportunity for municipalities to improve city lighting operational costs by using lamp management systems. A technology enables the design of a system that achieves advanced lamp management, and at the same time creates an outdoor wireless broadband network. It employs existing lamp posts with Wi-Fi modules integrated into an electronic ballast system.
An engine control system achieves controllable combustion across transients in a multi-cylinder HCCI engine. The method includes individually controlled fuel adjustment for each cylinder around sensed combustion parameters such as intake temperature, oxygen concentration and maximum rate of pressure rise. A closed-loop fuel control averages all cylinders' parameters and individually adjusts them to achieve cylinder-to-cylinder combustion balance, during both normal and load-bearing conditions.
