Abstract: A cordless blind includes a headrail, a bottom rail suspended from the headrail by a first cord and a second cord, a wall covering disposed between the headrail and the bottom rail, and a drive actuator. The drive actuator includes a spring motor, a spool coupled to the spring motor, a first tensioning mechanism, and a second tensioning mechanism. The first and second tensioning mechanisms are configured to impact a resistant force on movement of the first and second cords. The drive actuator may include a spool, a spring motor, a biasing element configured to provide a force biased against movement of the bottom rail, and a bias relief mechanism that is configured to provide for selective application and relief of the biasing force by the biasing element.

Abstract: A basketball backboard aiming device. The device includes a backboard member for attachment to a standard basketball hoop. The backboard has a front, planar surface. A linear array of indicia are disposed along the backboard, the array including a plurality of individual targets. Each of the targets is selectively viewable by a shooter disposed along a unique axis forming a preselected angle with respect to the plane of the backboard. One side of the angle is defined by a line of sight extending from the shooter to the target and the second side by the plane of the backboard. The selectively viewable target provides an aiming point for a shooter disposed anywhere along the line of sight when said player attempts a bank shot.
