Abstract: A vehicle ballast system for improving the balance of a vehicle. The system is particularly well suited for use in the bed of a pickup truck but is not limited to that deployment. The system includes one or more ballast units. Each ballast unit includes a frame set and a ballast element. The frame set retains the ballast element therein. The ballast element may be one or more concrete blocks. The frame set includes an upper frame and a lower frame. The respective frames are connected together in a manner to contain the ballast element using a front retaining rod and a rear retaining rod is preferably affixable to a bracket secured to the rear of the vehicle. A tether may be removably connected between the upper frame and a securing point of the vehicle. A shock-absorbing lanyard may be employed at the rear of the system as a restraint upon sudden deceleration of the vehicle.

Abstract: An electromagnetic flow probe for measuring fluid flow, and featuring interchangeable magnet and electrode lumen structures. A complex electrode lead pattern is incorporated in a lumen unit through which the fluid flow is conducted. The magnet structure is equipped with a magnetic field adjustment capability, and adjustable alignment lugs for receiving the lumen unit.
