System and method for preventing vehicle accidents in which GPS ranging signals relating to a host vehicle's position on a roadway on a surface of the earth are received on a first communication link from a network of satellites and DGPS auxiliary range correction signals for correcting propagation delay errors in the GPS ranging signals are received on a second communication link from a station or satellite. The host vehicle's position on a roadway on a surface of the earth is determined from the GPS, DGPS, and accurate map database signals with centimeter accuracy and communicated to other vehicles. The host vehicle receives position information from other vehicles and determines whether any other vehicle from which position information is received represents a collision threat to the host vehicle based on the position of the other vehicle relative to the roadway and the host vehicle. If so, a warning or vehicle control signal response to control the host vehicle's motion is generated to prevent a collision with the other vehicle.

Method for digitally determining the daily insulin regimen for a diabetic patient. The invention divides the patient's day into adjustable time intervals containing basal insulin dosage rates and Carbohydrate-to-Insulin Ratio(s) (for determining meal insulin doses). The invention identifies the Corrective Insulin doses over a time interval as an “error” in the Prescription Insulin (Basal Insulin+Meal Insulin). Methods involve first estimating the change to one of these two components of Prescription Insulin, and then determining the change to the other by subtracting from the error. One method estimates Change in Meal Insulin distributed among intervals proportional to old Meal Insulin. Another method lumps After-Meal Corrective Insulin together with Meal Insulin. Another method splits the interval at the After-Meal Corrective Dose and determines Basal from Time-Boundary Corrective Dose. Data may be obtained from the previous day, and a small fraction of error applied, leading to asymptotic reduction of error. Data may be obtained from recent history, and a larger fraction of error applied by doctor or automatic method.
