Patent number: 11403470Abstract: A storage unit stores a target term, a substitute term, a substitute translated term, and a representative term. The substitute translated term is a translation of the substitute term and is expressed in a second language. The representative term indicates a type of the target term and is expressed in the second language. A communication unit acquires a provisional translation that is a translation of a processed sentence from a first external device that has a translation function. When the storage unit does not store a target translated term that is a translation of the target term, a controller replaces the substitute translated term contained in the provisional translation with the representative term to generate a second display-purpose translated sentence, and then causes a display unit to display the second display-purpose translated sentence.Type: GrantFiled: October 11, 2019Date of Patent: August 2, 2022Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventor: Tomokazu Ishikawa

Patent number: 11257509Abstract: Techniques for EMD-based signal de-noising are disclosed that use statistical characteristics of IMFs to identify information-carrying IMFs for the purposes of partially reconstructing the identified relevant IMFs into a de-noised signal. The present disclosure has identified that the statistical characteristics of IMFs with noise tend to follow a generalized Gaussian distribution (GGD) versus only a Gaussian or Laplace distribution. Accordingly, a framework for relevant IMF selection is disclosed that includes, in part, performing a null hypothesis test against a distribution of each IMF derived from the use of a generalized probability density function (PDF). IMFs that contribute more noise than signal may thus be identified through the null hypothesis test. Conversely, the aspects and embodiments disclosed herein enable the determination of which IMFs have a contribution of more signal than noise.Type: GrantFiled: November 21, 2018Date of Patent: February 22, 2022Assignee: THE UNIVERSITY OF NEW HAMPSHIREInventors: Nicholas J.

Patent number: 11194998Abstract: An intelligent assistant records speech spoken by a first user and determines a self-selection score for the first user. The intelligent assistant sends the self-selection score to another intelligent assistant, and receives a remote-selection score for the first user from the other intelligent assistant. The intelligent assistant compares the self-selection score to the remote-selection score. If the self-selection score is greater than the remote-selection score, the intelligent assistant responds to the first user and blocks subsequent responses to all other users until a disengagement metric of the first user exceeds a blocking threshold. If the self-selection score is less than the remote-selection score, the intelligent assistant does not respond to the first user.Type: GrantFiled: July 24, 2017Date of Patent: December 7, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Kazuhito Koishida, Alexander A Popov, Uros Batricevic, Steven Nabil Bathiche
