Abstract: A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

Abstract: A multi-modal system providing for a single point of contact that can allow users to manage their personal contact information and contact lists, and connect to other users and businesses in a personalized, efficient, location-sensitive and organized manner. By accessing the system using any type of telephony-based device, a user can manage all of their personal and business contacts as well as perform generalized searches in public databases, such as white page and/or yellow page listings, or more personalized searches through databases of their business or personal contacts. A user may also, during a generalized search, go to a personalized search, and vice-versa. The system may also provide users with the opportunity to select certain businesses from their contact lists and allow these businesses to provide them with personalized data, either on demand or based on user-controlled permissions or areas of interest through various technologies including presence technologies.

Abstract: A multi-modal system and method for providing automated directory assistance that can be personalized, and provide current information and promotions from a variety of businesses customers in need of goods and services that can be location sensitive. The multi-modal system can contain a database where business information can be categorized using parameters such as location sensitivity to make dialogs between customers and the system more efficient and valuable. Search results can be presented to customers using algorithms that prioritize the results using weighting schemes based on factors comprising for example proximity, relevancy, location, availability of promotions, and accessibility, and that randomize the prioritized results. The system abstracts the interface to this contact point, allowing businesses and customers to use different types of communication devices, including voice, messaging, web, and wap.
