摘要:
A piston ventilator is disclosed herein which uniquely includes an oxygen blending module which supplies oxygen enhancement for aiding patients requiring respiratory treatment. The oxygen blending module supplies a preselected enrichment of oxygen to a piston and cylinder assembly wherein the amount of oxygen permitted to flow therein is continuously monitored and controlled according to the volume above the piston in the cylinder as calculated by a controller. The oxygen blending module includes a flow sensor which monitors the flow of supplemental oxygen into the piston and cylinder assembly, and further includes a primary oxygen control valve which restricts the flow of oxygen through the flow sensor to the piston and cylinder assembly depending on the difference between the calculated desired amount of oxygen and the target amount of oxygen provided to the controller.

A piston ventilator is provided which advantageously monitors the positive end expiratory pressure (PEEP) in a patient circuit for supplying breathable gas to a patient, and controls a shiftable valve element in an exhalation valve to regulate the amount of resistance during the exhalation portion of the patient's breath. The shiftable element is preferably an inflatable diaphragm which receives a pneumatic signal through a signal conduit. The pressure provided by the signal conduit is controlled by the amount of gas vented by a PEEP valve, wherein the greater the opening of the PEEP valve, the greater the amount of gas from the patient circuit is vented therethrough and consequently the less the restriction is provided in the exhalation valve. The primary source of pressure for the breathable gas is provided by a piston ventilator, with make-up pressurization in the patient circuit provided by a secondary source such as a blower to compensate for leakage and to provide pressurization for the signal conduit during the retraction of the piston within the cylinder and consequent exhalation portion of the patient's breath. Supplemental oxygen is provided to the patient circuit during retraction of the piston to ensure adequate oxygen enrichment at the incipient portion of the inhalation portion of the patient's breath.

A composite skull pin. The composite skull pin includes a core comprising a cone terminating in a distal point, the core being formed out of a substantially radiotranslucent material; and a jacket comprising a hollow cone terminating in a sharp distal point, the hollow cone of the jacket being sized and shaped so that it overlies, and closely conforms to, the exterior of the cone of the core. The jacket is formed out of a strong, hard material, and has a sufficiently small mass such that the composite skull pin has a low X-ray signature.

The same command surface on a page may be associated with unrelated components and applications. Each of the components registers the commands associated with a shared command surface that they will be utilizing. Each component may utilize an arbitrary number of commands that are associated with the command surface. The command manager acts as a message broker between the components on the page and the command surfaces. When a command that is associated with a command surface is received, the command manager dispatches the command message to the appropriate components.

Relative attributes of floating objects are disclosed. A user may obtain a floating object and specify that an attribute of the floating object is relative to a layout object of a page. In one aspect, the magnitude of relativity is determined, and the attribute of the floating object is maintained in accordance with the magnitude of relativity. In this manner, a page remains dynamically robust during page formatting operations and/or changes in page layout.
摘要:
A method and apparatus are provided for utilizing a document object model to manage document parts for use in an electronic document. The document object model enables a user to retrieve, insert, add, and delete document parts to and from an electronic document using a programmable interface from within a word processing application program. A document part programming interface is exposed in the object model and methods associated with the object model are called which return objects enabling the location and management of document parts in a document parts collection.
摘要:
A method, system, and computer-readable medium are provided for creating, inserting, and reusing document parts in an electronic document. According to a system, a word processing application program receives a selection of a document part category. In response to the selection of the document part category, a gallery of document parts is displayed in a user interface. A selection of a document part from the gallery is received and inserted in the electronic document without the need for additional formatting. The gallery of document parts defines a page layout for the electronic document. Document parts may be created within the user interface by modifying pre-built document parts.

Techniques include modifying a document using a latent transfer surface. An apparatus may comprise a document editing subsystem comprising a transfer surface creation module operative to embed a latent transfer surface in the document. A transfer control module may be communicatively coupled to the transfer surface creation module. The transfer control module may be operative to receive a transfer request to transfer media content for the document, and transfer the media content using the latent transfer surface in response to the transfer request.
