    Abstract: Described embodiments include an antenna system and method. The antenna system includes at least two surface scattering antenna segments. Each segment includes a respective electromagnetic waveguide structure, and a respective plurality of electromagnetic wave scattering elements. The wave scattering elements are distributed along the waveguide structure, have an inter-element spacing substantially less than a free-space wavelength of a highest operating frequency of the antenna segment, have a respective activatable electromagnetic response to a propagating guided wave, and are operable in combination to produce a controllable radiation pattern. A gain definition circuit defines a series of at least two radiation patterns selected to facilitate a convergence on an antenna radiation pattern that maximizes a radiation performance metric. An antenna controller sequentially establishes each radiation pattern. A receiver receives the desired field of view signal and the undesired field of view signal.

    Abstract: Positional applicator devices and methods are for application of stretchable electronics relative to subsurface features of an object. In some embodiments, a positional applicator device for applying a stretchable electronic device to a surface of an object includes: a holder for a stretchable electronic device; a signal emitter positioned to direct an emitted signal toward a surface of an object; a receiver positioned to detect a return signal from the surface of the object; circuitry operably connected to the signal emitter and the receiver, the circuitry configured to compare the emitted signal with the return signal in order to identify surface and subsurface features of the object; circuitry configured to compare the identified features with a map of surface and subsurface features of the object stored in memory; and a positioner, the positioner structured to apply the stretchable electronic device to a position on the surface of the object.

    Abstract: Methods and systems for monitoring usage of a telemedicine system are described. A monitoring system at a hospital or other central monitoring location provides for communication between personnel at a monitoring location (e.g. a medical care provider) and patient and/or caregiver at a patient location (e.g., the patient's home) via a telemedicine system. The telemedicine system may provide for audiovisual or other communication between the monitoring location and patient location, which may be in combination with medical monitoring or treatment provided with one or more associated article of medical equipment. The medical support monitoring system tracks the amount and type of usage of telepresence system and/or associated medical equipment. Tracked information regarding system usage may be used for various purposes, including billing, quality assurance, data analytics, including population studies of usage patterns, for example. Usage information may be linked to identity of patient, caregiver, or equipment used, or anonymized, depending upon the intended use.
