Abstract: Exemplary aspects involve a data-communications apparatus or system communicate over a broadband network with a plurality of remotely-located data-communications circuits respectively associated with a plurality of remotely-situated client entities. The system includes a platform that may be implemented as a unified-communications and call center platform that processes incoming data-communication interactions including different types of digitally-represented communications among which are incoming call, and that is integrated with a memory circuit including a database of information sets. Each of the information sets includes experience data corresponding to past incoming data-communication interactions processed by the platform, and with aggregated and organized data based on data collected in previous incoming interactions. The platform accesses the database and may: use past interactions and other data sources; and facilitate an automated self-service experience for users by resolving inquiries discerned through the incoming interactions; and/or effecting call-decision routing of incoming interactions to call-center agents or specialists.

Abstract: In certain examples, an epi instrument an ablation-delivery element and at least one epi magnet secured relative to the ablation-delivery element, and an endo instrument has at least one endo magnet and is configured with the endo magnet to facilitate positioning before ablation. The instruments are moved towards a first target ablation site, and then to a second ablation site, while the at least one ablation-delivery element and the endo instrument are drawn towards one another via magnetic forces and on either sides of tissue structure. The ablation-delivery element and the endo instrument are cooperatively configured to move together via the magnetic forces for the ablation. In more specific examples, the epi-endo system may use the epi-endo magnetic array to maintain a consistent contact force independent of the tissue thickness and/or may use a sensor feedback and controlled energy arrangement to provide feedback concerning the thickness(es) of the tissue area(s) targeted for the ablation.

Abstract: Certain examples are directed to an apparatus having a stretchable synthetic membrane material and series of patterned conductive or semiconductive sections. The stretchable synthetic membrane material may be provided with the series of patterned sections being integrated in or against the material (e.g., on similarly-configured robotic digits operating as a pair). One or more of these sections are electrically coupled to sensor circuitry which may also be secured to or embedded in the material. As the apparatus moves relative to an external object, various environmental parameters may be sensed via at least one sensor as the object and the digit(s) approach one another. Depending on how the sensor circuitry is configured, such parameters may include one or more of proximity, capacitance, temperature, impedance, contact with the object, and movement of the robotic member relative to the external object.

Abstract: In certain examples, methods, apparatuses and semiconductor-related structures are directed to nighttime-like electrical power generation by use of a spectro-angular selective emitter as an optimal radiative cooler and a thermoelectric power generator (TEG) having a hot side and a cold side. The cold side may be coupled to the spectro-angular selective emitter which is directed to or facing an atmosphere characterized by an absence of solar light. Power may be generated via the TEG based on energy directed from the spectro-angular selective emitter and by controlling or limiting ability of the spectro-angular selective emitter to absorb heat power at frequencies and/or angles where emission of the atmosphere is dominant.

Abstract: Various circuits and methods are disclosed for communications over AC power lines. In one example embodiment, a power line communication circuit includes an analog front end having a data-coupling circuit configured to communicatively couple communication signals to and from a set of AC power lines in the power line communication system. The analog front end also includes a noise reduction circuit that is coupled to the data-coupling circuit. The noise reduction circuit is configured to mitigate noise within a communication frequency band of the communication signals by filtering, from the communication signals, at least one frequency that is located outside of the communication frequency band and that has harmonics located within the communication frequency band. A receiver circuit is coupled to the noise reduction circuit and is configured to demodulate data from the communication frequency band of the filtered communication signals.
