Abstract: A secondary seat belt warning system for alerting a vehicle occupant when a seat belt is unbuckled. The secondary seat belt warning system includes an ignition switch for generating a signal indicating an ignition in an on position, a seat belt sensor for generating a signal indicating that the seat belt is unbuckled, and a seat belt indicator for producing an audible and visible indicator to the vehicle occupant. The secondary seat belt warning system also includes a control module to activate the seat belt indicator in response to the input from the ignition switch and seat belt sensor. The secondary seat belt warning system further includes a vehicle speed sensor to activate the secondary seat belt warning system when the control module receives a signal above a predetermined threshold from the speed sensor indicative of the vehicle speed.

Abstract: A method and system for determining bi-directional sneak current paths of an electrical/electronic circuit. The electrical/electronic circuit is converted into a corresponding schematic having a plurality of components and a plurality of line segments. A segment identifier is then inserted into each of the plurality of line segments. Next, a DC analysis is performed on the electrical/electronic schematic for each possible switch position combination to obtain a current value for each of the plurality of components. Bi-directional sneak current paths are then determined based on the plurality of segment identifiers and the current value for each of the plurality of components.
