Abstract: High speed cathodic protection control systems and methods provide for the delivery of deliver electrical current to a group of metal structures, such as well casings, in a sequential manner to prevent corrosion. A plurality of relays allow electrical current to flow from a power supply to subsets of the group of metal structures. The flow of electrical current is controlled by a microntroller which controls the relays to allow delivery of the electrical current at high speeds for short periods of time from the power supply to subsets of the group of metal structures in a sequential manner.

Abstract: Sports training apparatus has a substantially vertical base and a hoop-carrying member adapted to be attached to the base in a pre-selected position. The hoop-carrying member has attached at least one mounting bracket and hoop assembly of a mounting bracket supporting a hoop. The base can have a backboard attached also, with the backboard including at least one ball-support bracket adapted to receive and/or retain a ball, and the backboard is spaced from the base in a direction opposite the hoop. The hoop-carrying member can be adapted to be attached to the base in a plurality of pre-selected vertical positions, and the top portion of the base can have an angular portion carrying at least one hoop, in which the angular portion carries a hoop adapted to be located in a plurality of positions along its path.
