Abstract: An apparatus and method for displaying and dispensing merchandise at a point-of-purchase adjacent a display shelf secures at least one divider to a retainer plate affixed to the display shelf. An elongate lock bar extends beneath the divider, along a predominant portion of the length of the divider, and is coupled with the divider for unbiased sliding movement to selectively engage or disengage teeth carried by the lock bar and complementary teeth placed on the retainer plate to secure the divider in a selected location along the retainer plate or release the divider for movement to another selected location.

Abstract: An ice protection system for a structure has at least one electro-thermal heating element carried by the structure and a controller for selectively controlling the operation of each heating element. The controller operates each heating element according to a selected duty cycle defined by a pattern of time intervals, the controller selecting the duty cycle at least partially in response to measurements of ambient conditions about the structure.
