Abstract: A system for tilt-up concrete panel forming for use on a casting surface comprising an elongated base strip having an elongated groove in an upper surface, having a chamfered edge, and having a bottom surface adapted to be adhesively attached to the casting surface. The base strip has a support edge on the upper surface for receiving and supporting an elongated wooden panel form. A plurality of brackets each have a bottom section for mating with the elongated groove of the base strip at spaced intervals along the base strip, and the brackets further including a support section for supporting a side of the panel forms. Suitable clips can be added to the support sections of the brackets to impart a camber to an end of the concrete panel being formed.

Abstract: A driving behavior monitoring system mountable within a vehicle and having a board member on which are mounted first and second accelerometer devices for measuring acceleration in mutually orthogonal directions. Each accelerometer device includes an arm member in the form of a generally L-shaped crank or elbow. The crank is pivotable at the elbow joint thereof, and one arm of the crank is provided with a weight at the end thereof with the other arm having the free end thereof attached to one end of a tension spring, the other end of which is fixedly attached to the board member. A pair of electrical switch contacts are positioned in spaced relation on either side of the spring, with each contact being placed at approximately the same distance from the axial centerline of the spring. Movement of the weight translates to deflection of the spring in a direction orthogonal to its axis.
