Fuel management system for variable ethanol octane enhancehment of gasoline engines

Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and / or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

Activating a vehicle's own brake lights and/or brakes when brake lights are sensed in front of the vehicle, including responsively to the proximity of, and/or rate of closure with, a forward vehicle

InactiveUS7365769B1Efficient activationEffective and efficient and flexible and relatively economicalColor television detailsScene recognitionRear-end collisionDriver/operator
Any presence of brake light emissions of another vehicle to the forward of a subject vehicle is sensed in a color camera and microprocessor system that detects (i) red light(s) illuminations in excess of other colors, that are any of (ii) appropriately sized, (iii) appropriately located, (iv) simultaneously occurring, (v) spaced apart in separation, (vi) substantially horizontal, and / or (vii) of approximately of equal intensity, as would be appropriate to a single brake light, or to a pair of brake lights, as the case may be. The brake lights of the subject vehicle are preferably applied either during (i) the persistence of any detection of the brake light(s) of any other vehicle(s) to the forward, or (ii) normal application of the subject vehicle's own brakes. The forward-sensed rearward-propagated brake light signal is preferably delayed in propagation, limiting any propagation of minor perturbations in traffic. Optional application of the vehicle's own brakes may be conditioned upon (i) proximity to and / or rate of closure with a forward emission source as is preferably determined by angles, and / or upon (ii) rate of closure, speed or deceleration G force of the subject vehicle. The brake light signal, whether simple or sophisticated in either its development and / or presentation, beneficially alerts drivers to the rear of impending or actual slowing, thus deterring rear end collisions and promoting fuel economy.

Microprocessor system for the analysis of physiologic and financial datasets

A system and method for organization and analysis of complex and dynamically interactive time series is disclosed. One example comprises a processor based system for relational analysis of physiologic signals for providing early recognition of catastrophic and pathologic events such as pathophysiologic divergence. The processor is programmed to identify pathophysiologic divergence of at least one of first and second physiologic parameters in relationship to the other and to output an indication of the divergence. An object-based method of iterative relational processing waveform fragments in the time domain is described wherein each more complex waveform object inherits the characteristics of the waveform objects from which it is derived. The first physiologic parameter can be the amplitude and frequency of the variation in chest wall impedance or nasal pressure and the second parameter can be a measure or indication of the arterial oxygen saturation.

Method and system for an enhanced microprocessor

Systems and methods for modes of operation for processing data are disclosed. While executing a program in one mode the hazard checking logic present in the microprocessor system may be utilized to check or ameliorate the hazards caused by the execution of this program. However, when a program does not need this hazard checking, the microprocessor may execute this program in a mode where some portion of the hazard checking logic of the microprocessor may not be utilized in conjunction with the execution of this program. This allows the higher speed execution of these types of programs by eliminating checking for dependencies, the detection of false load / store dependencies, the insertion of unnecessary stalls into the execution pipeline of the microprocessor or other hardware operations. Furthermore, by reducing the use of hazard detection logic a decrease in power consumption may also be effectuated.
