In certain embodiments, a foam material is placed between the dasher board and a frame of the assembly. In embodiments, a spline connects adjacent dasher boards without rigid connection to adjacent vertical frame elements. In embodiments, the assembly is configured to provide puck play characteristics that are comparable to conventional dasher board assemblies.

Abstract

Disclosed are methods and interfaces for depicting a plurality of properties of a material, such as a haptic coating. In some aspects, gauges each expressing a property of the material may be displayed. Each property that collectively may describe the material may be defined along a gradient each of two opposing characteristics. Each of the physical properties may have an interrelationship with one or more of the other physical properties, such that when a particular value or quantity of one physical property is chosen, the other physical properties are constrained to a certain degree. The example gauges disclosed herein provide an interface that allows a user to easily understand these constraints and also allows for user friendly and intuitive manipulation of desired physical properties.
