Abstract: A wellbore servicing system and method are disclosed. The wellbore servicing system includes a casing string, a pressure testing valve, and a floating piston assembly. The pressure testing valve includes a housing and a sliding sleeve. The floating piston assembly is slidably disposed between the housing and the sliding sleeve. The sliding sleeve is slidably positioned within the housing and is transitional from a first position to a second position and from the second position to a third position. When the sliding sleeve is in the first or second positions, it blocks fluid communication via ports in the housing.

Abstract: Systems and methods for remote actuation of a downhole tool include a work string providing a flow path therein, a downhole tool coupled to the work string, at least one actuation device operatively coupled to the downhole tool and configured to act on the downhole tool such that the downhole tool performs a predetermined action, and an optical computing device communicably coupled to the at least one actuation device and configured to detect a characteristic of a substance in the flow path and trigger actuation of the at least actuation device when the characteristic is detected.

Abstract: A wellbore servicing system and method are disclosed. The wellbore servicing system includes a casing string and a pressure testing valve. The pressure testing valve includes a housing, a sliding sleeve, and a deactivatable locking assembly. The housing includes ports and an axial flowbore. The sliding sleeve is positioned within the housing and is transitional between first, second, and third positions. When the sliding sleeve is in the first and second positions, the sliding sleeve blocks fluid communication via the ports. When the sliding sleeve is in the third position, it does not block such fluid communication. Application of a fluid pressure transitions the sliding sleeve from the first to the second position, and a reduction in fluid pressure transitions the sliding sleeve from the second to the third position. When activated, the locking assembly inhibits movement of the sliding sleeve toward the third position.

In some embodiments, a circuit described herein comprises a first layer for receiving a transducer element array, a ground layer comprising at least one ground disposed over the first layer and a plurality of first vias corresponding to transducer elements of the array, the first vias extending through the first layer to the at least one ground and comprising first ends for receiving ground electrodes of the transducer elements and second ends electrically connected to the ground.

Abstract: The current document is directed to methods and systems that identify projects for which service consumers desire service provision and identify available candidate service providers that best match various project parameters and service-provision criteria determined by the automated system. Information describing the identified candidate service providers is presented to the service consumers by the systems to allow service consumers in order to facilitate their selection of service providers and scheduling of service provision. In one described implementation, service providers are matched to stock-keeping-unit (“SKU”) identifiers and location or locations. Service providers identified in the initial SKU-and-location-based matching process are then scored and ranked according to additional criteria and constraints, with information describing the highest-ranked service candidate providers provided to service consumers for selection and scheduling.

Abstract: An electronic device displays at least a portion of an electronic document with a predefined page layout at a first magnification level on a display; detects a first input indicating a first insertion point in the document, where the first insertion point is proximate to a first portion of text in the document; and in response to detecting the first input: selects a second magnification level different from the first magnification level, where the second magnification level is selected so as to display the first portion of text at a target text display size, and, while maintaining the predefined page layout of the document, displays, at the second magnification level, a portion of the document that includes the first portion of text.

Abstract: A rotorcraft including a fuselage, one or more motor-driven rotors for vertical flight, and a control system. The motors drive the one or more rotors in either of two directions of rotation to provide for flight in either an upright or an inverted orientation. An orientation sensor is used to control the primary direction of thrust, and operational instructions and gathered information are automatically adapted based on the orientation of the fuselage with respect to gravity. The rotors are configured with blades that invert to conform to the direction of rotation.

Abstract: In one aspect, ultrasound transducers are described herein comprising acoustic lenses having enhanced wear resistance. Such transducers can be employed in applications having harsh operating conditions, including veterinary applications. A transducer described herein, in some embodiments, comprises a polymeric acoustic lens having an acoustic velocity greater than 1.7 mm/?s, the polymeric acoustic lens arranged over an array of transducer elements wherein the array of transducer elements has a curvature in an elevation plane sufficient to compensate for wave refraction induced by the acoustic velocity of the polymeric acoustic lens to provide elevation focusing of an ultrasound beam generated by the transducer element array.

Abstract: Disclosed herein are systems, methods, and software for providing enhanced reliability for web services. In an implementation, a proxy service supports web services provided by a client application to at least an online service. While the client application is temporarily disconnected from the proxy service, the proxy service monitors for web services activity to occur in association with the web services provided by the client application to at least the online service. In response to the client application reconnecting to the proxy service after having been temporarily disconnected from the proxy service, the proxy service communicates activity information to the client application indicative at least of whether or not to query the online service with respect to the web services activity.

Abstract: An electronic device displays text of an electronic document on a display; displays an insertion marker at a first position in the text of the electronic document; detects a first horizontal gesture on a touch-sensitive surface; in response to a determination that the first horizontal gesture satisfies a first set of one or more predefined conditions: translates the electronic document on the display in accordance with a direction of the first horizontal gesture, and maintains the insertion marker at the first position in the text; and, in response to a determination that the first horizontal gesture satisfies a second set of one or more predefined conditions, moves the insertion marker by one character in the text from the first position to a second position in the text in accordance with the direction of the first horizontal gesture.
