Abstract: An electronically controlled burner management system for oilfield separators. The system includes an autonomous standing pilot spark ignition that includes a self-aligning clamp that holds the igniter to the burner nozzle. The self-aligning clamp enables rapid installation and removal, lowering the total cost of ownership. The autonomous spark ignition system incorporates temperature sensors to determine when the standing pilot needs to be relit, and can shut off the gas or other fuel flow to the standing pilot and the main burner when the pilot is not lit. The system increases oil and gas production from the well, reduces fugitive emissions of unburned gas, and improves oilfield worker safety. When installed or retrofitted into an existing oilfield separator, the original burner control components are left in place, allowing the user to revert to traditional operation in case of failure of any electronic component of the present system.

Abstract: A spacecraft payload subsystem includes a tracking receiver, an input multiplexer, an antenna pointing mechanism (APM) controller and a plurality of antenna reflectors. Each antenna reflector is mechanically coupled with a respective APM, and illuminated by a respective tracking feed element. Each respective tracking feed element is configured to receive an uplink beacon signal from the ground by way of one of the antenna reflectors and is coupled, by way of a respective pseudo-monopulse (PSM) coupler and the input multiplexer, to the tracking receiver. The tracking receiver is configured to receive multiplexed signals from the PSM couplers by way of the input multiplexer and output corresponding pointing error information to the APM controller. The APM controller is configured to send commands to one or more of the APMs. Each APM is configured to point a respective antenna reflector in response to the commands.
