Abstract: A method and system for targeted advertising in a communication system for connecting voice calls is provided. In accordance one embodiment of the present disclosure, there is provided a method for targeted advertising in a communication system for connecting a voice call, the method comprising: receiving a request to connect a voice call between a first communication device and a second communication device identified by a contact identifier; establishing a voice connection between the first communication device and a Voice over Internet Protocol (VoIP) gateway; transmitting a first audio advertisement over the voice connection between the first communication device and the VoIP gateway to be played on the first communication device; establishing a voice connection between the second communication device and the VoIP gateway; and connecting the voice call between the first communication device and the second communication device.

Abstract: A method and system for providing automated real-time updates of contact lists and instant messaging lists are described. In accordance with one embodiment, there is provided a method of generating dynamic contact information, comprising: providing two or more contact sources each comprising contact information defined for one or more contacts; generating a dynamic contact list comprising one or more electronic contact records with contact information from the contact sources in accordance with one or more rules for inclusion in the dynamic contact list, wherein the rules comprise one of both of a rule based on presence information of the contact and a rule based on location information of the contact; and transmitting the dynamic contact list to a first computing device for display thereon.

Abstract: A rotary saw blade having a substantially circular disc with opposed parallel faces and a centrally located opening through the disc to receive a drive member to rotate the disc. The outer edge of the disc has a plurality of equally spaced depth gauge protuberances located around its periphery and a pair of spaced holes extend through the disc adjacent to the outer edge at each protuberance. A saw tooth is attached to the disc on one face at alternate pairs of holes and a saw tooth is attached to the disc on the opposite face at the remaining pairs of holes. Each saw tooth has a cutting edge and a depth gauge and the depth gauge on each saw tooth has a shape and a size which are complementary with a depth gauge protuberance on the outer edge of the disc, and a face of the depth gauge on each saw tooth is in contact with a face of a protuberance on the outer edge of the disc. Each saw tooth is attached to the disc by rivets.

Abstract: A file guide for filing a depth gauge on a saw chain cutter having a cutting tooth with a cutting tip while the cutter is connected as a part of a continuous saw chain. The file guide is adapted to rest on the saw chain incorporating a plurality of cutters and includes an elongated base member having a slot to receive a portion of a depth gauge and at least one downward projection depending from said base member to engage with the cutting tooth to cause said base member to avoid contact with the cutting tip of the cutting tooth.
