Abstract: A content moderation system analyzes speech, or characteristics thereof, and determines a toxicity score representing the likelihood that a given clip of speech is toxic. A user interface displays a timeline with various instances of toxicity by one or more users for a give session. The user interface is optimized for moderation interaction, and shows how the conversation containing toxicity evolves over the time domain of a conversation.

Abstract: A method for online voice content moderation provides a multi-stage voice content analysis system. The system includes a pre-moderator stage having a toxicity scorer configured to provide a toxicity score for a given toxic speech content from a user. The toxicity score is a function of a platform content policy. The method generates a toxicity score for the given toxic speech content. The toxic speech content is provided to a moderator as a function of the toxicity score.

Abstract: A removable reel system includes a frame, a removable frame assembly, and a first spool. The first spool affixed to the frame when the removable frame assembly is coupled to the frame via a locking assembly disposed on the removable frame assembly. The first spool is removable from the frame by disengaging the locking assembly to uncouple the removable frame assembly from the frame. A second spool is attachable to the frame by engaging the locking assembly to couple the removable frame assembly to the frame.

Abstract: A reel system includes a fishing reel including a spool, an electrical module, and a multi-gear system. The electrical module is coupled to the fishing reel. The electrical module includes a motor configured to turn the spool. A first position in the multi-gear system is configured to turn the spool via the motor.

Abstract: A toxicity moderation system has an input configured to receive speech from a speaker. The system includes a multi-stage toxicity machine learning system having a first stage and a second stage. The first stage is trained to analyze the received speech to determine whether a toxicity level of the speech meets a toxicity threshold. The first stage is also configured to filter-through, to the second stage, speech that meets the toxicity threshold, and is further configured to filter-out speech that does not meet the toxicity threshold.

Abstract: A timbre vector space construction system for building a timbre vector space has an input. The input is configured to receive a first speech segment in a first voice and a second speech segment in a second voice. The system also includes a temporal receptive field to transform the first speech segment into a first plurality of analytical segments, and the second speech segment into a second plurality of analytical segments. Each of the first plurality of smaller analytical segments, and each of the second plurality of analytical segments have a frequency distribution that represents a different portion of the timbre data of the respective voices. The system also includes a machine learning system configured to map the first voice relative to the second voice in the timbre vector space as a function of the frequency distribution of the first plurality of analytical segments the second plurality of analytical segments.

Abstract: A firearm sight assembly comprises a rear base. The firearm sight assembly comprises a rear sight element movable with respect to the rear base between a lowered condition and an elevated condition. The rear sight element has a first pair of upwardly projecting first rear posts defining a first notch therebetween when in the lowered condition. The rear sight element has a second pair of upwardly projecting second rear posts defining a second notch therebetween when in the elevated condition. The first rear posts extend to a first height above the rear base, and the second rear posts extend to a second height above the rear base. The second height is greater than the first height.

Abstract: A method of building a speech conversion system uses target information from a target voice and source speech data. The method receives the source speech data and the target timbre data, which is within a timbre space. A generator produces first candidate data as a function of the source speech data and the target timbre data. A discriminator compares the first candidate data to the target timbre data with reference to timbre data of a plurality of different voices. The discriminator determines inconsistencies between the first candidate data and the target timbre data. The discriminator produces an inconsistency message containing information relating to the inconsistencies. The inconsistency message is fed back to the generator, and the generator produces a second candidate data. The target timbre data in the timbre space is refined using information produced by the generator and/or discriminator as a result of the feeding back.

Abstract: A prong-type harmonically de-tuned flash suppressor that is usable with a sound suppressor. As a consequence of its harmonic de-tuning, the flash suppressor does not produce an audible ping when the firearm to which it is attached is discharged, due to harmonic variance among the prongs of the flash suppressor. Harmonic variance, or de-tuning, of the flash suppressor is accomplished by varying centers of gravity of the prongs such that each prong of the flash suppressor has a different fundamental harmonic than each other prong. This harmonic de-tuning of the flash suppressor is accomplished while maintaining each prong at an equal length to each other prong, and while maintaining the general exterior appearance of each prong as being about the same as the general exterior appearance of each other prong. Centers of gravities of the prongs, and thus fundamental harmonics of the prongs, may be varied by placing payloads within the prongs which serve as harmonic dampers.
