The layers and protocols of an air interface layering architecture are designed to be modular and can be modified and upgraded to support new features, perform complex tasks, and implement additional functionality. Prior to commencement of data communication between a first entity (e.g., an access terminal) and a second entity (e.g., a radio network), a set of layers and / or protocols is selected for negotiation. For each selected layer and protocol (i.e., each attribute), a list of attribute values considered acceptable to the first entity is determined. The selected attributes and their associated attribute values are sent from the first entity and, in response, a list of processed attributes and their associated lists of processed attribute values are received. Each list of processed attribute values includes attribute values considered acceptable to the second entity. The layers and protocols in the first entity are then configured in accordance with the received list of processed attributes and their associated processed attribute values. Other features related to configurable layers and protocols are also provided.

A process for depositing porous silicon oxide-based films using a sol-gel approach utilizing a precursor solution formulation which includes a purified nonionic surfactant and an additive among other components, where the additive is either an ionic additive or an amine additive which forms an ionic ammonium type salt in the acidic precursor solution. Using this precursor solution formulation enables formation of a film having a dielectric constant less than 2.5, appropriate mechanical properties, and minimal levels of alkali metal impurities. In one embodiment, this is achieved by purifying the surfactant and adding ionic or amine additives such as tetraalkylammonium salts and amines to the stock precursor solution. In some embodiments, the ionic additive is a compound chosen from a group of cationic additives of the general composition [NR(CH3)3]+A−, where R is a hydrophobic ligand of chain length 1 to 24, including tetramethylammonium and cetyltrimethylammonium, and A− is an anion, which may be chosen from the group consisting essentially of formate, nitrate, oxalate, acetate, phosphate, carbonate, and hydroxide and combinations thereof. Tetramethylammonium salts, or more generally tetraalkylammonium salts, or tetraorganoammonium salts or organoamines in acidic media are added to surfactant templated porous oxide precursor formulations to increase the ionic content, replacing alkali ion impurities (sodium and potassium) removed during surfactant purification, but which are found to exhibit beneficial effects in promoting the formation of the resulting dielectric.

This invention is a neonatal airway adapter (10) with a sliding internal passage (54), which virtually eliminates void volumes (112) within the bore (76) of the airways, such that mixing of the exhaled gases with void gases is reduced, and the waveform of the breath is maintained without undue distortion. Furthermore, the virtual elimination of void volumes reduces the level of re-breathing. The neonatal airway adapter connects to endotracheal tube adapters in such a way as to nullify the effect of the differing internal diameters (20) and internal lengths which are used in ET adapters currently available. The cross section of the internal bore of the airway through which the breath flows from the ET adapter to the connector of the ventilator is maintained almost constant, especially in the region of the gas sampling point (66), to ensure that reasonable conditions of laminar flow, and accurate sampling are maintained.

A vacuum provides suction through the port and inner lumen.

The value of the rolling torque is measured at each frame through which a metal product passes, and the measurement is performed at the moment when said product reaches the following frame, at which point the frame at which the measurement is performed is switched over to torque regulation. The last frame reached by the product remains in speed regulation and it acts as a controlling frame for all other frames situated upstream therefrom so as to enable them to conserve torque equal to their respective reference torques by adapting their speeds. Once the reference torque measurements have been stored in the control system, regulation is obtained by making use of a distribution key for the stresses between the frames.

Disclosed is a method for enhancing upconversion luminescence of rare-earth doped particles comprising a host material, an enriched concentration of activator (emitter) and a sufficient concentration level of sensitiser, the method comprising subjecting the particles to increased irradiance. The increased irradiance is higher than presently used relatively low irradiance levels. Enhancing upconversion luminescence involves enhancing luminescence intensity, brightness and / or upconversion efficiency. Particles are preferably subjected to an irradiance power density sufficient to overcome or reverse concentration quenching. The activator preferably has an intermediate meta stable energy level which accepts resonance energy from the sensitiser excited state level. In another form, particles are designed to minimize or exclude quenchers from the upconversion system between sensitizer and activator, such as the core-shell particles wherein the core comprises the host material, sensitiser and the activator, and the shell comprises a material which prevents, retards or inhibits surface quenching.

Conflicts between the database-building and traversal phases are resolved by allowing the database bin size to be different from the display bin size. The database bin size is some multiple of the bin display bin size, and when there are multiple display bins in a database bin, each database bin is traversed multiple times for display, and the rasterizer discards primitives outside of the current display bin. This allows a trade off between memory bandwidth consumed for database building and bandwidth consumed for display, particularly when the display traversal is done multiple of times.
