Publication number: 20230081879Abstract: The disclosed systems and methods provide a framework for a proactive prediction of the toxic propensity of an article. Prior to the publication and/or reception of comments to online content, the disclosed framework determines the toxic propensity of the content's context and/or specific words, sentences, sentiments, tone or other messages receivable from consumption of the content. Thus, disclosed framework performs proactive forecasting of the content's toxicity propensityā€¯, which quantifies how likely the content is prone to incur or attract toxic comments. The framework can function and/or be configured to operate in a manner that can perform specifically adherent moderation actions that correspond to the content and control how the content can be interacted with, based on the toxic propensity determination, prior to the content's publication in an effort to thwart, prevent or stop toxic environments surrounding or stemming from the content from coming into existence.Type: ApplicationFiled: September 15, 2021Publication date: March 16, 2023Inventors: Fei TAN, Yifan HU, Kevin YEN, Changwei HU, Ben SHAHSHAHANI

Publication number: 20230052110Abstract: The present teaching relates to method, system, medium, and implementations for text processing. Upon receiving input data including an original token and a ground truth token label for the original token, a manipulation is applied to the original token to generate a manipulated token based on which to generate manipulated input data. Training data is generated based on the manipulated input data, the ground truth token label, and a ground truth action that, when applied to the manipulated token, yields the original token with the ground truth token label. A text moderation model is trained based on the training data.Type: ApplicationFiled: September 9, 2022Publication date: February 16, 2023Applicant: Verizon Patent and Licensing Inc.Inventors: Fei Tan, Yifan Hu, Changwei Hu, Keqian Li, Kevin Yen

Patent number: 8979513Abstract: A lead wire engaging structure includes a first engaging portion and a second engaging portion. One end of the first engaging portion and one end of the second engaging portion are integrally provided at a first mounting portion integrally provided at a second casing wall portion. The first engaging portion forms a first gap between the first engaging portion and the second casing wall portion, and engages four lead wires in cooperation with the second casing wall portion. The first gap allows the four lead wires to pass therethrough. The second engaging portion forms a second gap between the second engaging portion and the first engaging portion. The second gap allows the four lead wires to pass therethrough. The other end portion of the first engaging portion and the other end portion of the second engaging portion are coupled to each other by a coupling portion.Type: GrantFiled: October 7, 2011Date of Patent: March 17, 2015Assignee: Sanyo Denki Co., Ltd.Inventors: Kevin Yen, Jiro Watanabe, Hiromitsu Kuribayashi, Shigekazu Mitomo

Patent number: 8961121Abstract: A casing of a centrifugal fan includes a suction port forming wall portion, an opposed wall portion opposed to the suction port forming wall portion, and a sidewall portion connecting the suction port forming wall portion and the opposed wall portion. A tongue portion is provided at the sidewall portion. The tongue portion projects into an air passage in the vicinity of a discharge port to form a narrowed air passage portion within the air passage. A leading end surface of the tongue portion is shaped such that the width of the leading end surface increases from the suction port forming wall portion, where the suction port is formed, to the opposed wall portion. The tongue portion is shaped such that the projecting length of the tongue portion into the air passage continuously decreases from the suction port forming wall portion to the opposed wall portion.Type: GrantFiled: June 22, 2011Date of Patent: February 24, 2015Assignee: Sanyo Denki Co., Ltd.Inventors: Kevin Yen, Jiro Watanabe, Hiromitsu Kuribayashi, Shigekazu Mitomo

Patent number: 8764418Abstract: An impeller comprises an impeller body, a plurality of stems, a blade mounting member, and a plurality of blades. The stems radially extend with one end of each stem fixed to a portion of a circumferential wall of the impeller body in the vicinity of a suction port, and are arranged at intervals in a circumferential direction of the circumferential wall. The stems assist the impeller to suck air Jn an axial direction through a suction port during rotation of the impeller. The blade mounting member is disposed concentrically with the circumferential wall of the impeller body. The other end of each stem is fixed to the blade mounting member. The blades are arranged at intervals in the circumferential direction and extend along an axial line toward a second wall portion, with one end of each blade fixed to the blade mounting member.Type: GrantFiled: February 17, 2010Date of Patent: July 1, 2014Assignee: Sanyo Denki Co., Ltd.Inventors: Kevin Yen, Hiromitsu Kuribayashi

Patent number: 8680800Abstract: A driving system for a fan that enables an increase in motor current that may be supplied to excitation windings at the time of a maximum static pressure without increasing the rotational speed excessively when an amount of maximum air flow is provided. The fan driving system includes a drive signal generating circuit that generates drive signals, a motor driving circuit that supplies a motor current to the motor in accordance with the drive signals, a current detecting circuit (resistance) that detects the motor current, and a drive signal changing circuit. The drive signal changing circuit changes the drive signals generated by the drive signal generating circuit to restrict an increase in the motor current when the motor current becomes larger than a threshold.Type: GrantFiled: June 3, 2011Date of Patent: March 25, 2014Assignee: Sanyo Denki Co., Ltd.Inventors: Shigekazu Mitomo, Kevin Yen
