US11423317B2 Modeling characters that interact with users as part of a character-as-a-service implementation
In one embodiment, a character engine models a character that interacts with users. The character engine receives user input data from a user device, and analyzes the user input data to determine a user intent and an assessment domain. Subsequently, the character engine selects inference algorithm(s) that include machine learning capabilities based on the intent and the assessment domain. The character engine computes a response to the user input data based on the selected inference algorithm(s) and a set of personality characteristics that are associated with the character. Finally, the character engine causes the user device to output the response to the user. In this fashion, the character engine includes sensing functionality, thinking and learning functionality, and expressing functionality. By aggregating advanced sensing techniques, inference algorithms, character-specific personality characteristics, and expressing algorithms, the character engine provides a realistic illusion that users are interacting with the character.

US11423148B2 Preventing discovery of unique identifiers in firmware
Discovery of unique identifiers in firmware can be prevented.

A copy of the firmware tables may be maintained separately from the anonymized version of the firmware tables to enable authorized utilities to obtain the computing system's unique identifiers.

A power transmission device includes: a cylindrical member including an opening formed at a first end in an axial direction, and a wall portion formed at a second end in the axial direction; and a planetary gear set received within the cylindrical member; a carrier of the planetary gear set which includes a protruding portion protruding toward an outer circumference side, and the protruding portion being positioned between the wall portion and a ring gear of the planetary gear set, wherein the carrier is integrally formed with a hub portion of a clutch; the hub portion is positioned on a wall portion side of the carrier; and an outermost circumference portion of the protruding portion is positioned radially outside of an outermost circumference portion of the hub portion.
US11421770B2 Power transmission mechanism
A power transmission mechanism including a planetary mechanism, an electronically controlled clutch, and a motor generator. The planetary mechanism is coupled to an input shaft and first and second output shafts. The planetary mechanism includes a differential element rotating the first and second output shafts at different rotation speeds. The planetary mechanism outputs a torque input to the first and second output shafts. The electronically controlled clutch includes first and second clutch plates. The first clutch plate is coupled to a member different from the differential element. The second clutch plate is coupled to the differential element. The electronically controlled clutch allows the differential element to rotate the first and second output shafts at the different rotation speeds when the first and second clutch plates are released. The electronically controlled clutch restricts a rotation speed difference in response to engaging between the first and second clutch plates.
US11421768B1 Torque converter having stamped pilot plate with cross flow to pressure chambers
A torque converter comprising a cover arranged to receive torque, an impeller having an impeller shell non-rotatably connected to the cover, and a turbine in fluid communication with the impeller and including a turbine shell is provided. In embodiments, the torque converter includes a piston plate; and a seal plate disposed axially between the piston plate and the turbine, wherein the piston plate is sealed to the seal plate at an outer diameter thereof. A pilot flow plate is disposed axially between the cover and the seal plate, wherein the pilot flow plate is fixed to the cover on a first axial side and fixed to the seal plate on a second, opposite axial side.
US11421766B2 Gear train and vehicle installing gear train
Provided are a gear train and a vehicle installing the gear train. The gear train is configured to transmit power from a rotating electrical machine to a driving wheel through a differential and a drive shaft. The gear train includes a plurality of shafts on a plurality of axes lying different from each other and a plurality of gears that is disposed respectively on the plurality of shafts. At least one of the plurality of gears is an internal gear.
US11421765B2 Actuating mechanism with a planetary roller screw mechanism
An actuating mechanism has a main rotational drive and a roller screw mechanism coupled to the main rotational drive. The roller screw mechanism has a screw, a nut, and a plurality of rollers. One of the screw and the nut is coupled to the main rotational drive, while the other is movable relative to the rollers both translationally and rotationally. The roller screw mechanism also has an annular guide for circumferential and axial retention of the rollers. The annular guide contains a cylindrical sleeve that extends axially outward from one of the annular heels beyond the nut. The screw extends into a bore of the sleeve, and the sleeve is coupled to a secondary rotational drive.
