Abstract: An array of individual elements (10) having reduced control circuitry as compared to existing devices. Sets of elements (11) share a memory cell (12), such that each memory cell (12) has the same fanout as other memory cells (12). Each element (11) in a set is switched to an on or off state via a reset line (13) that is separate from that of the other elements (11) in that set. Data is loaded in split bit-frames during a set time period, such that each split bit-frame contains only the data for elements (11) on one reset line (13). Thus, the same memory cell (12) can be used to deliver data to all elements (11) in its fanout because only one element (11) in the fanout is switched at a time.

Abstract: Boat mooring devices to secure a boat or other floating object at a relatively fixed location on the surface of a body of water, which allow vertical movement of the boat, or floating object, in response to change in the water level where the boat is connected to at least one vertically extending shaft which extend upwardly above the surface of the water by ring-like floats having split sections so the boat can be connected to the rings and the shaft can be received through the split sections of the rings regardless of the height of the shaft. Closure devices are provided to retain the rings on the shafts for longitudinal movement thereon, but hold the boat in position and telescoping shafts are provided where the rings are attached adjacent the distal ends thereof so the shafts are extended and retracted in response to change in water level.
