Publication number: 20210145441Abstract: A system and method of variable velocity control of an instrument by a computer-assisted device includes a computer-assisted device that includes an actuator and one or more processors. To perform an operation with an instrument coupled to the computer-assisted device, the one or more processors are configured to set a velocity set point of the actuator to an initial velocity, monitor force or torque applied by the actuator to actuate the instrument, when the applied force or torque is above a first force or torque limit, determine whether a total duration of a set of pauses occurring during the operation of the instrument is below a maximum pause threshold, and in response to determining that the total duration is below the maximum pause threshold, pause the operation of the instrument.Type: ApplicationFiled: January 27, 2021Publication date: May 20, 2021Inventors: David W.

Publication number: 20210150482Abstract: Methods, systems, and devices supporting global message threads are described. A thread server may receive a communication message associated with a first set of user identifiers (e.g., the author and recipients of the message) and may extract a thread identifier from the message. The thread identifier may associate the message with one or more additional messages (e.g., from the same thread of messages), where the one or more additional messages may be associated with different user identifiers. The thread server may upsert the received communication message to a stored set of messages associated with a root indicating the thread identifier. If the thread server receives a query indicating the thread identifier from a user, the thread server may retrieve all of the messages associated with the thread identifier from persistent memory based on the query, including messages that are not associated with the user identifier for the querying user.Type: ApplicationFiled: November 18, 2019Publication date: May 20, 2021Inventors: Narek Asadorian, Noah William Burbank

Patent number: 10992612Abstract: A database server may identify mentioned names in a body of a message and extract the names using name identification heuristics and algorithms. The service retrieves or utilizes a distributed connection graph to identify contacts associated with the parties to the conversation that may match or be similar to the mentioned name. Contacts may be scored based on similarities between the extracted name the names associated with nodes of the graph, as well as other factors. The highest scoring contact may be surfaced or displayed to one or more of the parties to the communication message.Type: GrantFiled: January 30, 2019Date of Patent: April 27, 2021Assignee: salesforce.com, inc.Inventors: Noah William Burbank, Gabriel Starr Krupa, Bradford William Powley, Alexis Roos

Patent number: 10973519Abstract: A system and method of variable velocity control of a surgical instrument in a computer-assisted medical device includes a surgical instrument having an end effector located at a distal end of the instrument, an actuator, and one or more drive mechanisms for coupling force or torque from the actuator to the end effector. To perform an operation with the instrument, the computer-assisted medical device is configured to set a velocity set point of the actuator to an initial velocity and monitor force or torque applied by the actuator. When the applied force or torque is above a first force or torque limit it is determined whether a continue condition for the operation is satisfied. When the continue condition is satisfied the operation is paused and when the continue condition is not satisfied it is determined whether forced firing of the actuator should take place.Type: GrantFiled: January 27, 2017Date of Patent: April 13, 2021Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: David W.

Patent number: 10835331Abstract: Surgical tools having a two degree-of-freedom wrist, wrist articulation by linked tension members, mechanisms for transmitting torque through an angle, and minimally invasive surgical tools incorporating these features are disclosed. An elongate intermediate wrist member is pivotally coupled with a distal end of an instrument shaft so as to rotate about a first axis transverse to the shaft, and an end effector body is pivotally coupled with the intermediate member so as to rotate about a second axis that is transverse to the first axis. Linked tension members interact with attachment features to articulate the wrist. A torque-transmitting mechanism includes a coupling member, coupling pins, a drive shaft, and a driven shaft. The drive shaft is coupled with the driven shaft so as to control the relative orientations of the drive shaft, the coupling member, and the driven shaft.Type: GrantFiled: January 2, 2019Date of Patent: November 17, 2020Assignee: Intuitive Surgical Operations, Inc.Inventor: William A.

Patent number: 10828030Abstract: Surgical systems and related methods verify the presence of an unfired surgical cartridge mounted to a surgical instrument. The cartridge includes an input that is actuated in a firing direction to operate the cartridge. An actuation input that is limited to less than or equal to a predetermined magnitude is generated. The actuation input includes at least one of a torque or a force. The actuation input is transferred to an output of a surgical instrument to attempt to actuate the output opposite to the firing direction by a predetermined amount. The output is drivingly coupled with the cartridge input when the cartridge is mounted to the surgical instrument. The resulting actuation of the output is measured and compared with a threshold actuation amount. A determination is made that the cartridge is present and unfired when the resulting actuation of the output is less than the threshold actuation amount.Type: GrantFiled: October 26, 2012Date of Patent: November 10, 2020Assignee: Intuitive Surgical Operations, Inc.Inventors: David W.

Patent number: 10779896Abstract: Mechanisms, assemblies, systems, tools, and methods include an offset drive shaft within an independently rotating member. An example method of transmitting torque through an offset drive shaft routed within a rotatable main shaft includes supporting a main shaft to rotate relative to a base so that the main shaft rotates about a main shaft rotational axis. A drive shaft is supported to rotate relative to the main shaft so that the drive shaft rotates about a drive shaft rotational axis that is offset from the main shaft rotational axis. The drive shaft is engaged with a drive feature having a drive feature rotational axis that is fixed relative to the base as the main shaft rotates. The main shaft is rotated relative to the base. The drive feature is rotated relative to the main shaft so as to rotate the drive shaft relative to the main shaft.Type: GrantFiled: August 15, 2017Date of Patent: September 22, 2020Assignee: Intuitive Surgical Operations, Inc.Inventors: Gregory W.
