Abstract: Provided is a virtual reality (VR) device, system and framework for generating VR continuum experience choreographed to a physical procedure incorporating at least one procedural action associated with a physical sensation and potentially inducing an anxiety or pain response. The VR continuum experience can modify perceptions of pain and anxiety associated with the procedure. The virtual reality device is configured to allow device control via a device user interface accessible to an operator other than the wearer (i.e. a medical practitioner), to allow the operator to control device calibration and virtual reality (VR) experience start while the apparatus is worn by the wearer, and to provide one or more VR experiences each associated with a physical procedure.

Abstract: Real-time topic analysis for social listening is performed to help users and organizations in discovering and understanding trending topics in varying degrees of granularity. A density-based sampling method is employed to reduce data input. A lightweight NLP method is utilized for topic extraction which provides an efficient mechanism for handling dynamically-changing content. In embodiments, the social analytics system further helps users understand the topics by ranking topics by relevance, labeling topic categories, and grouping semantically-similar topics.

Abstract: User feedback regarding sentiments of social posts is used to improve sentiment assignment for social analysis. The user feedback is used to generate sentiment tuning data, which may include assignments between reference sentiments and reference social posts. Sentiments of new social posts may be determined by applying the sentiment tuning data to an analysis of the new social posts. Sentiments of new social posts may also be determined by applying entries from one or more lexical dictionaries to the new social posts using natural language processing. At least some of the entries can be automatically generated from the user feedback or can be supplied by a user separate from the user feedback.

Abstract: The present invention relates generally to the field of frequency modulation, and in particular to dual port frequency modulators. The present invention provides a frequency modulator comprising a phase lock loop circuit (108) for receiving and modulating a carrier signal according to the low frequency component of a modulating signal, the phase lock loop circuit comprising a voltage controlled oscillator (118) for outputting a modulated carrier signal and a loop filter (116) for outputting a steering voltage to the VCO, the VCO having a tank circuit (120) comprising a voltage controlled capacitance (VAR1). The frequency modulator also comprises an external voltage controlled capacitance (122) which is arranged to modulate its capacitance according to a high frequency component of the modulating signal, the second voltage controlled capacitance being coupled to the tank circuit.
