Abstract: Automated motor vehicle battery voltage protection is provided by setting voltage trip points for increasing engine speed and for shedding selected electrical loads. The system is effected by programming a vehicle body computer which communicates with, and exerts control over, various vehicle system controllers over one or more controller area networks. The body computer is programmed to monitor battery voltage and initiates an increase in engine speed first, and if that fails to restore a minimum battery voltage level, begins shedding loads in a predetermined order.

Abstract: Vehicle theft deterrence is affected by requiring the entry of an enabling code to prevent disablement of vehicle operation. System operational variables may be programmed by operators. The system is substantially integrated with existing vehicle control systems.

Abstract: This invention concerns a method of reducing the gaping values of railway tracks made of steel to less than 3.6 mm. It is characteristic of this invention that the rolled and leveled rails are heated briefly, i.e., for approx. 10 to 25 sec, until reaching a maximum temperature of 100.degree. C. in the rail head and a maximum of 260.degree. C. in the web, and then they are allowed to cool again immediately.
