Abstract: A braking assembly for use with a roller skate, the roller skate being wearable by an intended user having a leg, a foot extending from the leg and a hand. The roller skate has a frame, a foot receiving portion coupled to the frame for receiving the foot of the user and first and second wheels rotatably mounted to the frame, the first and second wheels defining respectively a first wheel radius and a second wheel radius. The first and second wheels further define respectively a first wheel circumferential surface and a second wheel circumferential surface.

Abstract: A water storing apparatus (10) suitable for outdoor and indoor installation, and adapted to maintain drinking water within a predetermined range of temperature. The apparatus has a water tank (12) containing the drinking water with a temperature sensor (24) for sensing the water's temperature. The temperature of the drinking water can be changed by either a heater or a cooler, which are both in contact with a heat conductive member (30) itself in thermal contact with the water tank (12). In this manner, the water temperature can either be increased or decreased as needed to be maintained within an appropriate predetermined range.
