摘要:
A connector which joins two opposing sections of coil tubing or coil tubing to coil tubing tools so as to enable torque applied from one section to be transmitted to the other section is provided. The connector employs varying width and depth grooves into which portions of the sections of coil tubing are deformed so as to create the torque transmitting connection between the connector and sections of coil tubing. Each of the grooves have a narrow width portion and a wide width portion and corresponding shallow depth and deep depth portion. The narrow width portion of one of the grooves is approximately 180° out of phase from the narrow width portion of the other varying width groove.

Embodiments of the hybrid tool string include coiled tubing and jointed tubing, as well as a means typically located at the connection of the coiled and jointed tubing for sealing the fluid flowpath through the bore of the hybrid tool string. Embodiments of the hybrid tool string may use a pressure-activated valve tool attached in series between the coiled tubing and the jointed tubing, which allows for sealing of the bore by application of pressure. Embodiments of the pressure-activated valve tool may use a flapper in conjunction with a sleeve to seal the bore. The novel hybrid tool string may be used to service a well.

A wellbore servicing apparatus, comprising a first mandrel movable longitudinally along a central axis and rotatable about the central axis, an orienting member configured to selectively interfere with movement of the first mandrel along the central axis, and a second mandrel connected to the first mandrel and configured to rotate about the central axis when the first mandrel rotates about the central axis. A method of orienting a wellbore servicing tool, comprising connecting an orienting tool to the wellbore servicing tool, identifying a predetermined direction, increasing a pressure within the orienting tool, rotating a portion of the orienting tool in response to the increase in pressure within the orienting tool, and rotating the wellbore servicing tool in response to the rotating of the portion of the orienting tool.

An improved electrode headset is provided for the acquisition of electroencephalographic (EEG) brain signals detected at the scalp of a human subject. The headset includes an elastic fabric cap having a chinstrap, which cap is fitted closely to the scalp. The cap has openings at those selected locations on the scalp to which removable and disposable electrodes are to be removably connected to the scalp. A positioning unit, of a generally flat and flexible plastic material, is attachable to the cap by corresponding hook-and-loop fasteners on the outer surface of the cap and the inner surface of the positioning unit. The positioning unit has a base portion and two opposite leg portions, each with slits. Flat beams are adjustably connected through the slits to the leg portions and base portion. Each beam carries a screw member which adjustably applies pressure to electrode holders and a flexible electrode extractor strap to which the electrode holder is attached. Each electrode holder is snap fastened to an electrode positioned within a cap opening.

An optical accelerometer, gravitometer, and gradiometer have a light source, a beam splitter, a light medium, and a plurality of mirrors. The light beam from the light source is split into two beams that counter-propagate through the accelerometer. The acceleration experienced by the accelerometer causes a phase shift in the beams, and this phase shift is used to calculate the acceleration.

A database navigation system simplifies the navigation and use of sales target information in a database. The salesperson, i.e., the user, begins navigating and using the database by logging into the secured system using a computer. Once logged in, the system displays a Leads Worksheet that lists the sales targets, or “suspect”, from the database assigned to that user and the name of a prospecting process, i.e., a prospecting cycle, that the user will follow with that target. The prospecting cycle comprises of several management-defined steps. Once the user creates a To-Do list of the targets to pursue that workday, the user goes to an Action Page. Here, the user completes the actions in the step of the prospecting cycle for each selected sales target using the tools provided. The system creates a log, i.e., a history, of the user's actions including phone calls, e-mails, video transmissions, and the like as related to the target. The history of user interaction with target data creates metrics used by the salesperson and management to evaluate performance and generate performance reports. All the above is achieved by navigating two screens with a computer mouse and with no input of information (save the optional comment) into the database by the salesperson. Thereby, this essentially automates the “cold call” sales prospecting process.

Web pages may be dynamically generated in response to a web request from a client. The web request specifies a dynamic content resource that declares one or more server-side controls having personalizable properties. Personalization refers to the ability for server-side controls to save property values to persistent storage and is not necessarily limited to a user-specific data management. Personalization also refers to retrieving the property values from persistent storage when the server-side controls are instantiated in order to dynamically generate the web page reflecting the persistent personalization data. The personalized property values may also be output with the HTML data of the resulting page and sent to the client for display.
摘要:
The described systems and methods are directed at defining web content navigation. The disclosed technique enables the development of web content for a scenario without having to create every navigational control that is needed to manage the flow through the web content in the scenario or to write non-declarative server-side logic to control navigation. This method determines a declaration in a source file for a web page. The declaration is associated with an object. The method determines the views associated with the object where each of the views includes a user-interface. A flow for navigating through the views is determined. The views are rendered in accordance with the navigational flow.
