Abstract: Methods for distinguishing particles in a fluid sample are disclosed. In one embodiment, the method includes acquiring a background SIMI image and a background brightfield image of a membrane filter while the membrane filter is free of a fluid sample, introducing a fluid sample onto the membrane filter, acquiring a SIMI image and a brightfield image of filtered particles resting on the membrane filter, distinguishing between the filtered particulates and the membrane filter based on the background SIMI image, generating a particle mask based on the SIMI image, and detecting beads via the particle mask. Methods for distinguishing particulates include distinguishing between viable and non-viable cell populations, distinguishing between cellular and non-cellular particulates, distinguishing between biological and non-biological particulates, distinguishing between first and second protein types, determining stability of monoclonal antibody drugs, identifying beads in a cell therapy, and detecting bacteria.

Abstract: Described herein are new crystalline forms of the MAGL inhibitor 1-(1-(2-(pyrrolidin-1-yl)-4-(trifluoromethyl)b enzyl)-1,8-diazaspiro[4.5]decane-8-carbonyl)-1H-pyrazole-3-carboxylic acid, or a pharmaceutically acceptable salt thereof.

Abstract: A re-timer device includes transceiver circuitry. The transceiver circuitry includes clock generation circuitry and first receiver circuitry. The clock generation circuitry generates a first clock signal. The first receiver circuitry receives the first clock signal and a first input signal. The first receiver circuitry generates a first frequency offset value based on the first input signal and the first clock signal. The first input signal has a first frequency and the first clock signal has a second frequency different than the first frequency. The first receiver circuitry outputs the first frequency offset value.

Abstract: An electrosurgical end effector for a surgical tool to perform teleoperated surgical operations. The electrosurgical end effector comprises a first end effector jaw; a second end effector jaw coupled to the first end effector jaw; and a coupling pin configured to rotatingly couple the first end effector jaw to the second end effector jaw so as to cooperatively rotate open and close about an axis of rotation. The electrosurgical end effector further comprises an actuation mechanism coupled to an end of the first end effector jaw to rotate the first end effector jaw about the coupling pin; an otomy feature coupled to the second end effector jaw; and a first electrical conductor to electrically couple the otomy feature to a generator. In one embodiment, the otomy feature is electrically activated by contact with a cam portion of the first end effector jaw, when opened beyond a predetermined jaw angle.

Abstract: The present invention is directed to processes for making various polymorphs of tucatinib, designated herein as Form I, Form II, and Form III of tucatinib. These forms can then be used to prepare pharmaceutical formations containing tucatinib. Tucatinib is a tyrosine kinase inhibitor that is indicated for the treatment of breast cancer.

Abstract: A surgical instrument is disclosed. The instrument includes a handle portion, a body portion extending distally from the handle portion and defining a first longitudinal axis and an articulating tool assembly defining a second longitudinal axis and having a proximal end. The articulating tool assembly is disposed at a distal end of the body portion and is movable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position in which the second longitudinal axis is disposed at an angle with respect to the first longitudinal axis. The instrument also includes an articulation mechanism configured to articulate the articulating tool assembly, the articulation mechanism including an articulation sensor assembly configured to transmit a sensor signal to a microcontroller which is configured to determine an articulation angle of the articulation assembly.

Abstract: Systems and methods of controlled grasping and energy delivery include a computer-assisted device. The computer-assisted device includes an end effector and one or more processors. The end effector includes a first jaw, a second jaw, and a plurality of electrodes for delivering energy. The one or more processors are configured to grasp a material using the first jaw and the second jaw, determine characteristics of the grasp, determine characteristics of the material, and control one or more of the grasp or energy delivery by the plurality of electrodes based on the determined characteristics of the grasp and the determined characteristics of the material.

In some embodiments, the characteristics of the grasp include one or more of applied pressure, jaw angle, jaw separation, force, torque, or wrist articulation.

Abstract: Methods and systems for improved failover techniques are described herein. A failure associated with a content source may lead to a computing device becoming unable to output all or part of content that was requested from the content source prior to the failure. The computing device may have received a portion of a manifest associated with the content prior to the failure. The failover techniques described herein may enable the computing device to continue receiving portions of the content despite the failure. For example, an additional portion of the manifest may be modified such that the computing device may request additional portions of the content from another content source without requiring a retuning procedure.

Abstract: There are provided pressurized surgical instruments for use in pressurized surgical environments. The pressurized surgical instruments include pressurizing systems for maintaining a neutral or positive pressure flow within the surgical instrument during use. The pressurizing systems include a primary sensor for detecting the pressure of the surgical environment and a pressurizing mechanism for balancing the pressure of the surgical instrument with the surgical environment. The pressurizing mechanism includes a controller to receive and compare the signal sent from the primary sensor to the ambient or internal instrument pressure and a pressure delivery system to provide positive pressure to the interior of the surgical instrument in response to a signal received from the controller. The sources of pressure for the pressure delivery systems may be external or self contained within the surgical instrument.
