Abstract: Embodiments of an enclosure assembly to enhance cooling of a hydraulic fracturing direct drive unit (DDU) during operation are included. The enclosure assembly may include an enclosure body extending at least partially around an enclosure space to house the DDU for driving a fluid pump. The enclosure assembly may include one or more heat exchanger assemblies connected to the enclosure body for cooling a process fluid associated with one or more of the DDU and the fluid pump, and which may be configured to draw air into the enclosure space from and external environment, toward one or more radiator assemblies to cool the process fluid, and along an airflow path through the enclosure space. One or more outlet fan assemblies may be operative to discharge air from the enclosure space to the external environment to maintain a desired temperature of the enclosure space.

Abstract: A method provides a set of predicted responses to a user. The method includes receiving a message from a user, the message having natural language information. The method includes processing, using cognitive switching logic (CSL), the natural language information and information from previous messages from the user. The method includes identifying, using CSL, a context of the natural language information based on the information from the previous messages. The method includes identifying, using CSL, at least one knowledge domain which contains a response to the message, based on the identified context and on user persona information. The method includes retrieving a response from each identified knowledge domain. The method further includes, in response to retrieving more than one response, transmitting feedback to CSL to refine identifying the at least one knowledge domain until only one response is retrieved. The method further includes presenting the one response to the user.

Abstract: Process for purifying 3,4-dihydroxyphenylglycol (DHPG) from any part of the plant, from the products or by-products derived from olive trees or any other vegetable product of the families Oleaceae, Orobanchaceae, Plantaginaceae, Compositae, Lamiaceae, Acanthaceae and/or Scrophulariaceae, and which comprises 1 or more steps wherein the initial product is introduced into at least one ion-exchange resin column, and in potentially subsequent steps the product eluted in the preceding column is introduced into an ion-exchange resin and/or a non-ionic adsorption resin column. Moreover, it relates to the DHPG extract obtainable by means of the process disclosed and to the applications thereof.

Abstract: An apparatus for use in gynaecological operations includes a support and a mounting assembly for mounting the support to an operating table. A vertical member is supported in a vertical orientation by the support and a horizontal bar is supported in a substantially horizontal orientation by the vertical member. An annular vaginal plug is supported by and is axially movable along the horizontal bar. A plug locking assembly is provided for locking the vaginal plug in a selected axial position along the horizontal bar. A uterine driver may be introduced through the abdominal wall that has a handle and a uterus engagement tip with omni-directional movement in the released position. The engagement tip is connected to the uterine driver by a flexible member.

Abstract: A knock-down table that can be quickly assembled and disassembled for compact storage or shipping. The apparatus includes a table top, a plurality of detachable legs and a ring-shaped brace. Coupling members are provided on the bottom side of the table top and project downwardly therefrom. Sockets are formed in the top ends of the table legs for slidably receiving the coupling members. The ring-shaped brace interconnects each of the legs and maintains the structure in a substantially rigid configuration.

Abstract: The present invention relates to a method for obtaining purified hydroxytyrosol from products and by-products derived from the olive tree by means of two-step chromatographic treatment. The invention uses a non-activated ion exchange resin chromatographic method, followed by a second treatment on an XAD-type absorbent non-ionic resin which concentrates and completely purifies the hydroxytyrosol by means of elution with a methanol or ethanol:water dissolution (from 30 to 33%). The method of the invention can also be applied to two-phase pomaces, three-phase pomaces and stones if they are subjected to a steam explosion process.

Abstract: The present invention is a double-jointed, tendon-driven revolute joint, a decoupled tendon-driven wrist, an antibacklash mechanism, a robot control system, and a robot manipulator incorporating the double-jointed, tendon-driven revolute joint, decoupled tendon-driven wrist, and antibacklash mechanism. The robot manipulator is a microsurgical teleoperated robot with actuators located at an actuator base. The overall system architecture includes a slave robot manipulator coupled to an amplifier chassis which is coupled to a control chassis. The control chassis is coupled to a workstation with a graphical user interface. Components of the robot manipulator are categorized into a mechanical sub-system, an electronics sub-system, a servo-control sub-system, and a high-level software control sub-system.

Abstract: A robot manipulator controller for a flexible manipulator arm having plural bodies connected at respective movable hinges and flexible in plural deformation modes corresponding to respective modal spatial influence vectors relating deformations of plural spaced nodes of respective bodies to the plural deformation modes, operates by computing articulated body quantities for each of the bodies from respective modal spatial influence vectors, obtaining specified body forces for each of the bodies, and computing modal deformation accelerations of the nodes and hinge accelerations of the hinges from the specified body forces, from the articulated body quantities and from the modal spatial influence vectors. In one embodiment of the invention, the controller further operates by comparing the accelerations thus computed to desired manipulator motion to determine a motion discrepancy, and correcting the specified body forces so as to reduce the motion discrepancy.

Abstract: This invention is a robot control system based on a high level language implementing a spatial operator algebra. There are two high level languages included within the system. At the highest level, applications programs can be written in a robot-oriented applications language including broad operators such as MOVE and GRASP. The robot-oriented applications language statements are translated into statements in the spatial operator algebra language. Programming can also take place using the spatial operator algebra language. The statements in the spatial operator algebra language from either source are then translated into machine language statements for execution by a digital control computer. The system also includes the capability of executing the control code sequences in a simulation mode before actual execution to assure proper action at execution time. The robot's environment is checked as part of the process and dynamic reconfiguration is also possible.
