A method, wireless service node, and wireless communication system, are provided to manage wireless service usage and service node migration in the wireless communication system. A registration request from a wireless device (108) is received. A charging session associated with the wireless device (108) is established with a billing server (124). Wireless service usage is associated with the wireless device (108). The wireless device (108) is determined to be migrating to a new wireless service node (114). Information associated with the current charging session is transferred to the new wireless service node (114). Following the transfer, the service usage information pertaining to the same session is maintained and transferred by the new wireless service node to the billing server at appropriate time intervals and as per dynamic rules set in the billing server.

In one aspect, the invention concerns a method of operating a chatbot to engage in a conversation with a correspondent the method comprises building a profile having plural profile variables for the correspondent; and during the conversation with the correspondent; selecting a node in the conversation data structure for processing based on the one or more profile variables, and processing the node to follow a conversation path based on the node's coded instructions and / or relationship with other nodes. In another aspect, the method comprises the steps of attempting to match the received input message with a node in the conversation data structure of the chatbot; if a matched node is found, selecting the matched node for processing; but if a matched node is not found, selecting a node for processing using a fuzzy search, or using a default procedure.

A data communication system and an associated network node implementation is disclosed that, in certain embodiments, uses single-channel bi-directional communication links between nodes to send frames of data. The network nodes can be connected together in a ring or daisy chain topology with data frames sent in alternating directions through the bi-directional links. Such networks initially configured in a physical ring topology can tolerate single point failures by automatically switching to a logical daisy chain topology.

A “Wearable Electromyography-Based Controller” includes a plurality of Electromyography (EMG) sensors and provides a wired or wireless human-computer interface (HCl) for interacting with computing systems and attached devices via electrical signals generated by specific movement of the user's muscles. Following initial automated self-calibration and positional localization processes, measurement and interpretation of muscle generated electrical signals is accomplished by sampling signals from the EMG sensors of the Wearable Electromyography-Based Controller. In operation, the Wearable Electromyography-Based Controller is donned by the user and placed into a coarsely approximate position on the surface of the user's skin. Automated cues or instructions are then provided to the user for fine-tuning placement of the Wearable Electromyography-Based Controller. Examples of Wearable Electromyography-Based Controllers include articles of manufacture, such as an armband, wristwatch, or article of clothing having a plurality of integrated EMG-based sensor nodes and associated electronics.

The current invention describes methods of transesophageal access to the neck and thorax to perform surgical interventions on structures outside the esophagus in both the cervical and the thoracic cavity. It describes a liner device made of a complete or partial tubular structure, or a flat plate, the liner having means to facilitate creation of a side opening, which may include a valve. The liner with its side opening form a port structure inside the esophageal lumen. The port structure allows elongated surgical devices to pass through a perforation across the full thickness of the esophageal wall to outside location, in a controlled way. The elongated surgical devices can be diagnostic scopes, therapeutic scopes, manual elongated surgical devices, robotic arms or the like. After being deployed outside the esophagus, the surgical devices can access structures outside the esophagus, in the neck and thorax in 360 degrees of freedom around the esophageal circumference. These structures can be bony, cartilaginous, spinal, vascular, soft tissue, deep tissues, lymph nodal, cardiac, pulmonary, tracheal, nervous, muscular or diaphragmatic, skin and subcutaneous tissues of the neck, skin and subcutaneous tissues of the anterior chest wall, skin and subcutaneous tissues of the skin of the back, and skin and layers of the breast.
