Abstract: A nasal prong or nasal mask cannula system which has at least one of the following features: to enhance the cannula tubing at the port base of the oxygen source to minimize “crimping” and diminished oxygen delivery; to design a cannula that will expand in length as needed and shorten as needed without loss of pressure (PSI) of oxygen from start point of oxygen source to patient; to provide a device such as a clasp or clip attached to the cannula which clasp or clip may be attached to the patient's clothing to relieve pressure or weight exerted by the cannula tubing on the patient's ears and keep the cannula close to the patient's body; to provide storage means for storing extra length of tubing; to provide a warning device to alert the patient when oxygen levels or oxygen flow rate are low or that the battery energizing the warning device is low; to provide a timing device to alert the patient to change the cannula after a prescribed period of time; to provide means for stylizing or personalizing the cannula

Abstract: In a rotating disk reactor for growing epitaxial layers on substrate or other CVD reactor system, gas directed toward the substrates at gas inlets at different radial distances from the axis of rotation of the disk has both substantially the same gas flow rate/velocity and substantially the same gas density at each inlet. The gas directed toward portions of the disk remote from the axis may include a higher concentration of a reactant gas than the gas directed toward portions of the disk close to the axis, so that portions of the substrate surfaces at different distances from the axis receive substantially the same amount of reactant gas per unit area, and a combination of carrier gases with different relative molecular weights at different radial distances from the axis of rotation are employed to substantially make equal the gas density in each region of the reactor.

Abstract: A double-pass reverse osmosis (RO) separator module having two stages of RO filtration in a single assembly, including a radially outer RO assembly that surrounds a radially inner RO assembly, wherein each RO assembly includes an RO separation medium. The outer RO assembly may be used for a first-pass of RO filtration in which a first-pass feed liquid enters the outer RO assembly and is separated via reverse-osmosis to provide a permeate liquid and a concentrate liquid. The permeate liquid exiting the outer RO assembly may flow via fluid passages to the inner RO assembly for a second-pass of RO filtration in which the first-pass permeate liquid enters the inner RO assembly as a second-pass feed liquid and is separated via reverse-osmosis to provide a second-pass (i.e., double-filtered) permeate liquid.

Abstract: In a rotating disk reactor (1) for growing epitaxial layers on substrate (3), gas directed toward the substrates at different radial distances from the axis of rotation of the disk has substantially the same velocity. The gas directed toward portions of the disk remote from the axis (10a) may include a higher concentration of a reactant gas (4) than the gas directed toward portions of the disk close to the axis (10d), so that portions of the substrate surfaces at different distances from the axis (14) receive substantially the same amount of reactant gas (4) per unit area. A desirable flow pattern is achieved within the reactor while permitting uniform deposition and growth of epitaxial layers on the substrate.

Abstract: A system generates and retrieves relevant electronic information required by a user initiating an electronic search on the system. The system comprises a user-interactive search engine and a knowledge database, which stores knowledge information that is formatted. Additionally, the system includes a plurality of functional software modules that enables a user to complete an interactive search and find a solution to a task based on entered context information and keywords. A list of keywords is displayed to the user and the user selects those keywords that are relevant to the solution desired. The search engine looks for the articles containing the identified keywords. If no article is found with the search terms, the search is expanded to the Internet. The user may then modify the information returned from the Internet, format the information and save the information as a new recipe.
