Abstract: This invention provides bioluminescence resonance energy transfer (BRET) system that comprises four parts: 1) a bioluminescent protein that has luciferase activity; 2) an acceptor fluorophore that can accept the energy from the bioluminescent protein when they are associated, in the presence of the appropriate substrate; 3) a modulator that influences the proximity or the orientation of the bioluminescent protein and the fluorophore, and 4) an appropriate substrate to activate the luciferase activity of the bioluminescent protein. The components of this system interact to influence the spatial relationship between the bioluminescent protein and the fluorophore, that is demonstrated by the light emission from the system. The modulator can be a single entity, covalently attached to both the bioluminescent protein and the fluorophore, it can be two separate entities, each linked covalently to either the bioluminescent protein or the fluorophore, or an alternative configuration that falls within the scope of the invention. Thissystem can be used in both in vivo or in vitro assays to detect molecular changes in a wide variety of applications, and is amenable to automation. In particular, it is useful for assaying protein interactions, enzyme activities and the concentration of analytes or signaling molecules in cells or in solution.

Title: Improved waveform transitioning method and apparatus for multi-shot fuel systems
Inventor: MCGEE BRIAN G
IPC: F02M57/02
Filed: 2001-06-12
Abstract: A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injector, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions, the controller being operable to output a fuel injection signal to the fuel injector to deliver multiple fuel shots to the cylinder during a fuel injection event based upon the sensor signals.

The controller sets single check fuel and engine speed hysteresis values, and determines fuel and engine speed changes. If both the fuel and engine speed changes are greater than the respective hysteresis values, the active waveform is changed to a potential waveform, which is found in a lookup table or map. The waveform will also change if the fuel change is continuously greater than a loop fuel hysteresis value, which value is larger than the single check fuel hysteresis value, for longer than a selected period of time such as approximately 3.8 seconds.
