  • Patent number: 11974828
    Abstract: Techniques for operating a kinematic structure by manual motion of a link coupled to the kinematic structure include a system having a kinematic structure configured to support an instrument and a processor. The processor is configured to place the system in a clutching mode; transition the system from the clutching mode to a set-up mode in response to detecting a joint operation of the kinematic structure; while in the set-up mode, determine an input displacement of a link from an initial positional relationship relative to a portion of the kinematic structure to a displaced positional relationship relative to the portion of the kinematic structure; and while in the set-up mode and in response to the determined input displacement, drive the kinematic structure so that the link returns toward the initial positional relationship relative to the portion of the kinematic structure.

  • Publication number: 20240131268
    Abstract: A fluid injector system for delivering a multi-phase fluid injection to a patient and methods of fluid delivery is disclosed. Methods of creating and using a multi-aspect fluid path impedance model of the injector system are used. Modeling and adjustment of factors that affect impedance and prevent or reduce backflow, reduce the likelihood of fluid flow rate spikes and provide more accurate flow rates and mixing ratios of fluids may be repeated or happen essentially continuously during an injection. The adjustments may be determined before the injection or determined and/or adjusted during the injection. The determination may include sensor feedback commonly used in injectors such as pressure and position feedback as well as other sensors. In all cases, the user can be notified of adjustments through on-screen notices and/or through the recordation of the injection data by a control device of the injector at the conclusion of the injection.

  • Patent number: 11941358
    Abstract: A user using a messaging application may be in conversations with multiple people and may inadvertently send a message intended for a first person to a second person. The user may be warned before making such mistakes by processing the text of an entered message and/or the text of the conversations with a mathematical model. A match score may be computed that indicates the match between the entered message and the conversation in which it was entered. Where the match score indicates a possible mistake, a warning may be presented to the user. In some implementations, a match score may be computed using a conversation encoding vector and a message encoding vector. In some implementations, a match score may be computed by processing a sequence of tokens for the conversation and the entered message that includes special token separators.

  • Patent number: 11763230
    Abstract: Machine learning-based approaches are used to detect trends of behavior and anomalous events from customer support messages between customers and customer support agents or other appropriate resources in an electronic environment. For example, for a plurality of time periods, a prediction model can be trained. The prediction models can be trained on messages that correspond to each prediction models' period of time. The prediction models can process messages to determine a score (e.g., a representative confidence score) for the time period a prediction model is associated with. For a selected time period, a model (e.g., a trend detection model) can be applied to the scores for time periods before the selected time period to determine whether the score for the selected time period is associated with an anomalous event. Thereafter, an alert can be presented with, for example, the messages that triggered the alert, among other such information.

  • Publication number: 20230134071
    Abstract: Apparatuses, methods, and systems for identifying a target location to an occupant are provided. The apparatus comprises a laser rotatably coupled to a body of the apparatus, and at least one sensor connected to the body. The at least one sensor is configured to detect an alarm, and when the at least one sensor detects the alarm, the laser is configured to emit a laser beam to indicate a target location to an occupant. The method for identifying or indicating a target location comprises detecting, by a sensor of an apparatus, an alarm, in response to detecting the alarm, outputting, by the sensor, a signal, in response to the signal, activating a laser rotatably coupled to a body of the apparatus to identify or indicate the target location. The invention may be used for emergency situations to indicate a target location such as an exit for occupants of a building or residence.

  • Patent number: 11551004
    Abstract: In some applications, it may be desired to process a message to determine an intent of the message, where the intent indicates the meaning of the message. An intent classifier may be used to determine the meaning of a message by processing the message to compute a message embedding vector that represents the message in a vector space. Each possible intent may be represented by a prototype vector, and the intent of the message may be determined by comparing the message embedding to one or more prototype vectors, such as by selecting an intent whose prototype vector is closest to the message embedding. An intent classifier may be used, for example, (i) to implement an automated communications system with states where each state is associated with a subset of the possible intents or (ii) for processing usage data of a communications system to update the intents of the communications system.

  • Patent number: 10984781
    Abstract: A plurality of conversations may be processed to obtain one or more representative conversations to allow a better understanding of the plurality of conversations. A representative conversation may be determined by representing each conversation as a sequence of states where a state may represent messages with similar meanings. Distances may be computed between pairs of conversations, and the conversations may be clustered using the distances. To obtain a representative conversation for a cluster of conversations, a representative sequence of states may be obtained for the cluster and a representative message may be obtained for each state of the sequence of states. The representative conversation may then be presented to a user.
