Abstract:
A back-up battery system is provided for use with a real-time clock of an on-board device controller. In its normal operation, the real-time clock (RTC) is powered by a primary power source, such as a vehicle battery. When the primary source is interrupted, the back-up battery system is invoked to provide back-up power to the RTC. The system includes a low voltage dry cell battery mounted within a fuse component configured for electrical engagement within the vehicle fuse block. In one embodiment, a relay is interposed between the fuse component and the RTC to make and break the back-up power circuit in response to the state of the primary power source. In another embodiment, the battery within the fuse component is replaceable, with the fuse component including a base and a removable cap. In still another embodiment, the battery within the fuse component is a rechargeable battery, and the back-up power system includes a recharging circuit operable with the primary power source.

Abstract:
A method and apparatus for generating calibration information in which a subfile type is defined for each of a plurality of categories of data including (1) engine control data, (2) engine family data, (3) vehicle interface data, (4) software sequencing data, (5) electronic configuration data, and (6) memory configuration data. A separate subfile is created in memory for each of a plurality of individual sets of data in each of the data categories. Each subfile is automatically provided with line checksums, a cyclic redundancy code, date information, a subfile type identifier, and a subfile authorization level, and data entries are automatically verified base on rules stored in memory in a rules file, each of the subfile types having an associated rules file, and each of the rules files defining criteria for individual data items and for interrelationships between data items in its associated subfile type. A compatibility file is created in memory to identify subfiles of one type which are compatible with a subfile of another type. Each subfile and the compatibility file are distributed individually via an electronic communication link to multiple service computers programmed to determine compatibility among selected subfiles based on information stored in the compatibility file and to assemble compatible subfiles into a calibration file for a particular engine control module.
