Abstract: A snow melting system and method for operating a snow sensor is provided. The snow melting system includes a controller, a heating system, and a snow sensor. The snow sensor comprises a support structure and a cap. The support structure includes a proximal end and a distal end, where a first plane defined by the distal end is angled with respect to a second plane defined by the proximal end. The cap is disposed at the distal end of the support structure and comprises a top surface, a side surface arranged orthogonal to the top surface, and a chamfer that extends between the side surface and the top surface.

Abstract: A communication network is described that allows legacy devices to access an IMS network. The communication network includes a switching system, an IMS network, and a non-IMS network. The switching system includes a subscriber database that is pre-provisioned with identities of IMS subscribers using legacy devices. When in operation, a calling party places a call through a legacy device. The switching system receives the call and accesses the subscriber database based on a calling party identifier (e.g., a phone number, URL, etc) to determine if the calling party is an IMS subscriber. If the calling party is an IMS subscriber, then the switching system routes the call to the IMS network. If the calling party is not an IMS subscriber, then the switching system routes the call to the non-IMS network.
