An apparatus and method for resurfacing ice surfaces such as ice hockey playing surfaces wherein an ice shaving blade system and an ice scooping system operate over the entire width of the playing surface. The articulation region comprises a reduced thickness region of the support hoop that prevents kinks from forming in the support hoop when the apparatus is contracted to its delivery state, and curved regions that close the mouth of the sac to prevent material escaping from the sac when the apparatus is collapsed for removal. The chamber contains a fluid that needs to be cooled. The computer parses the description of the module to identify a port of the module, and to obtain information about the port.
