  • Publication number: 20060259852
    Abstract: The present invention is directed towards systems and methods for providing access to content or services. According to one embodiment a system for providing access to content or services comprises one or more servers and one or more client software applications. An internal network accessible at a client location provides a communications pathway to a content management system for receiving data describing content or services over the internal network from the client software applications and for managing such data. A network access device is communicatively coupled to the internal network and receiving content or service for presentation of content or services to the user through the media viewer.

  • Patent number: 6164584
    Abstract: An apparatus for winding a wire about a component having a plurality of slots. The apparatus includes a rotatable gripper mechanism for gripping the component and rotating the component about a transverse axis of the component, the gripper mechanism being shaped to guide the wire into a slot of the component. The apparatus also includes a wire guide for guiding the wire into the slot of the component as the component is rotated about the transverse axis.

  • Patent number: 4954005
    Abstract: A coupling device includes a first support member which is connected to the arm of a robot and which supports a second support member for precision universal tilting and axial and/or rotary movement from an aligned normal position. The second support member supports robotic tooling, and a set of springs or springs and ball members or fluid actuated piston bias the support members to the normal position. An electrical control circuit is effective to stop movement of the robot arm in response to minute tilting or axial or rotary movement of the second support member in the event the tooling or article carried by the tooling is accidentally hit or overloaded. A set of semi-circular rings and auxiliary springs are attached to the support members for producing a substantial biasing force towards the normal position, and a set of construction balls and corresponding seats are used to establish a precision normal position.
