A container is provided for shipping and storing a pre-wetted and preconditioned microfluidic “sipper” chip. The container contains both dry compartments and wet compartments. A base contains a fluid-filled reservoir configured to house the capillaries. The opening of the reservoir is sealed with an O-ring. The plastic mount of the chip rests on the base in a dry compartment. The upper surface of the chip contains several wells containing fluid. A gasket is provided with plugs configured to be disposed within and seal the wells. Alternatively, the wells are first sealed with a foil film adhered to the well openings with an adhesive and a gasket is disposed between the foil and a cover, which is removably attached to the base. When the cover is closed, the gasket and O-ring seal the wet compartments to prevent leakage and to slow evaporation.

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.

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.

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.

A system for removing material from a flowing liquid, where the system includes one or more cartridges, where each cartridge has an outer permeable wall and an inner permeable wall that form a media region between the walls, where a media is disposed within at least part of the media region to remove at least a portion of the material from the flowing liquid, the cartridge also having an inner cartridge lumen in communication with the inner permeable wall, and a cartridge outlet in communication with the inner cartridge lumen; a cartridge chamber having a treatment region that houses the one or more cartridges, where the cartridge chamber also includes a chamber inlet to accept the flowing liquid, and a chamber outlet to discharge treated liquid; and an actuatable valve positioned outside the one or more cartridges, where the valve controls a flow rate of the flowing liquid within the treatment region by actuating in response to a change in a level of the liquid in the treatment region.
摘要:
A method and apparatus for protecting against a buffer over flow attack. In one variation, an executable software program is divided into an executable image, a data image, and an execution history image. The operating system processes an executable statement in the executable image. Other statements are processed in the data image. In a second variation, the execution history image is made use of in addition to the tasks of the first variation. Each statement is classified as either mutable or immutable. The usage of statements is recorded in the execution history image. If a mutable statement has over-written an immutable statement memory location, then the program is terminated. Optionally, the entire program is re-mapped using the execution history image such that immutable statements cannot over-write mutable statements.

A system and method for the automated testing of a telecommunications system. In operation, the automated test system may be used to test the functionality of telephony applications residing on telecommunications equipment and to validate the data contained within related databases. In an exemplary embodiment, the automated test system is used to test the functionality of an automated messaging system and the accuracy of associated call detail records (CDR) located within a CDR database. A capture/playback tool is preferably used to emulate the interaction of a test person on a workstation of the test system to thereby automate the testing process.
