Abstract: Cement slurry injected or delivered into a wellbore during cementing operations can be positively placed with a positive placement tool. The tool can be located along to a casing string and have a mandrel with a tubular centralizer sleeve rotatably fit thereabout, the centralizer sleeve having one or more radial guides extending longitudinally thereon. Reciprocal stroking of the casing string causes a helical drive arrangement, acting between the mandrel and the centralizer sleeve, to drive the centralizer sleeve longitudinally along a length of the mandrel while concurrently rotating the centralizer sleeve thereabout. The rotational movement of the centralizer sleeve provides positive impetus to force the injected cement slurry fully about the casing string.

Abstract: The present disclosure relates to methods and intermediates useful for preparing a compound of formula I: or a co-crystal, solvate, salt or combination thereof.

Abstract: A wood chipper having a rotatable drum configured to reduce the size of wood fed into the wood chipper; a sensor configured to sense a speed of rotation of the rotatable drum; and a controller operably connected to the sensor. The controller is configured to cut power to the rotatable drum when the speed of rotation of the rotatable drum drops below a pre-set threshold value. The controller is operably engaged with a centrifugal clutch that is engaged to enable the rotatable drum to be rotated. When the speed of drum rotation drops below the threshold value because debris is slowing down rotation of the drum, the centrifugal clutch is disengaged by dropping engine speed. Disengagement of the centrifugal clutch cuts power to the drum and rotation thereof ceases so that the debris may be cleared.

Abstract: Systems and methods according to the present invention utilize improved sleeves for insulating fluid (i.e., liquid and/or gas) conduits. For example, some blow dryers are equipped with a flexible conduit to convey heated air from a heater element to a nozzle for such purposes as material handling, material drying, or even hair drying, such as pet or other animal hair drying. An improved insulating tubular sleeve is provided with securing and/or mounting mechanisms to assist in maintaining sleeve position along a conduit and to reduce heat transfer externally from the conduit, such as by preventing direct contact between animal hair or skin or other materials and the conduit.

Abstract: Disclosed are some implementations of systems, apparatus, methods and computer program products for encrypting and securely storing session data during a browser session using a session-based cryptographic key. The session data may be decrypted during the browser session or other browser sessions using the session-based cryptographic key or other backwards compatible session-based cryptographic keys. In addition, session-based cryptographic keys may be shared among browser sessions to enable encrypted session data to be decrypted across page refreshes and browser tabs.

Abstract: Disclosed are examples of systems, apparatus, methods and computer program products for providing a security model for component-based web applications. Documents for a web-based application are received, with the application containing custom components and Application Programming Interface (API) components. A Document Object Model (DOM) is processed corresponding to the web-based application, with the custom and API components modeled in hierarchical form. For each custom component, a key is assigned in accordance with the rules of capability security, accessible custom components are identified for which the custom component can provide the assigned key, a virtual DOM is generated for the custom component with the component and identified accessible custom components being modeled in hierarchical form, and the custom component is prohibited access to all inaccessible custom components.

Abstract: A motion-assisted positioning arm for a medical procedure. The positioning arm includes a base, an arm coupled to the base, and an end effector coupled to the arm. The arm includes a plurality of arm segments. The arm includes a plurality of joints for connecting the arm segments. The end effector may be manipulable with six degrees of freedom in a task-coordinate space based on motion by at least one joint in the plurality of joints. The positioning arm includes a processor to: detect manipulation of and determine forces or torques acting on the end effector; determine a surgical mode for constraining movement of the end effector in the task-coordinate space; determine an end effector velocity based on the determined forces or torques and the surgical mode for moving end effector; and apply at least one joint space movement based on the end effector velocity.

Abstract: An optical performance monitor comprises a first stage configured to receive a multiplexed optical signal. The first stage is tunable over a period. The first stage periodically filters the multiplexed optical signal over an optical channel to produce a fine filtered optical signal. A second stage is coupled to the first stage and has a second-stage transfer function. The second stage receives the fine filtered optical signal and produces one or a plurality of interfered optical signal pairs. A third stage is coupled to the second stage and has a third-stage transfer function. The third stage receives the optical signal pairs and demultiplexes the optical signal pairs to produce a plurality of demultiplexed optical signals. The combination of the second-stage transfer function and the third-stage transfer function is flatter over the optical channel than the third-stage transfer function.

Abstract: Techniques for decoupling data, sent by a data source, from how the data is sent to a user by a system are described. A system may include an application program interface (API) that enables a data source to simply provide data. The system may determine whether and how to send the data to a user(s) as a notification. The system may determine a modality by which to send the notification to the user. The system may use presence data to determine which device should be used to output the notification to the user. The system may cause the device to output the notification to the user using the modality.

Abstract: A wrap removal device includes (a) an engagement surface configured to receive a container having an outer wrapping and (b) one or more delivery elements disposed on or in the engagement surface. The one or more delivery elements are configured to generate energy that one or more of melts, cuts, or weakens the outer wrapping along a path without melting, cutting, or modifying the container. The wrap removal device can quickly remove the outer wrapping without damage to the container.
