Abstract: A safety alert system for a vehicle including, a controller at least one detector and at least one alarm. The controller is connected to the vehicle. The detector is mounted to the vehicle, and is in communication with the controller. The alarm is communicatively coupled to the controller. The detector senses an approaching vehicle velocity and distance of the approaching vehicle. The detector sends a signal to the controller representative of the velocity and distance of the approaching vehicle. The controller uses the signal to determine if the approaching vehicle is decelerating within a predetermined level, and the controller activates the alarm if the deceleration is not within the predetermined level.

Abstract: An RFID tag supported on a carrier self locks to a work piece. The work piece, such as a beam, is modified to form an elongated slot in the beam having an opening along one face of the beam. A slip located is located in the elongated slot, the slip being bent on a fold following an axis generally parallel to the direction of elongation of the elongated slot and formed so that the slip retains a degree of spring force urging a pair of edges of the slip against interior major faces of the elongated slot. The slip is oriented in the elongated slot with the fold relatively away from the opening relative to the pair of edges so that at least one of the pair of edges catches on one of the interior major faces. The fold defines first and second sections of the slip on opposed sides of the fold, the first section forming a base section which carries a radio frequency identification tag and the second section forming a latch section, which is narrower than the base section.

Abstract: Rotation and positioning of a rotary index table supported from a base is effected using a cam supported from a conveyor and cam follower lock, with the conveyor and cam follower lock being mounted on a carriage set for radial movement on the base inwardly and outwardly with respect to the axis of rotation of the rotary index table, and a plurality of cam followers depending from the rotary index table.
