Abstract: The present invention provides for a sensor and signal for unsafe occurrences. In the preferred embodiment, a severe braking alert system is coupled to a vehicle for notifying trailing drivers that the vehicle is braking severely. Sensors in the system detect when the vehicle exceeds a predetermined deceleration threshold value thereby causing one or more of the vehicle's existing rear lights to flash for a predetermined time period. Alternatively, a dedicated light(s) can be incorporated. The flashing light(s) alerts trailing drivers to the dangerous condition and provide them with valuable information about the vehicle's rate of deceleration. This allows the trailing drivers to apply the appropriate amount of braking power to their vehicles in order to prevent a rear-end collision. Alternative flashing schemes can also be incorporated to notify the trailing driver about the degree of severity with which the lead vehicle is decelerating.

Abstract: A special marker is disclosed that is affixed to a stationary or moving web near the lateral web edge to designate defective material. When edge trim is removed from the web, the trim removal device also cuts-off the front end of the marker so that the remaining portion is momentarily flush with the new web edge. This cutting action activates the remaining portion of the marker so that a component of the marker advances to extend out beyond the new web edge such that it is visible after the marker is wound into the rewind roll. This ability to see where the web was initially marked, after edge trim is removed, eliminates the conventional inaccurate and wasteful practice of remarking the web.
