Certain methods comprise providing a substrate surface; exposing the substrate surface to a vapor comprising a precursor having a structure represented, without limitation to specific orientation, by: wherein R1 and R2 are each independently H or any C1-C3 alkyl group, R4 is trimethylsilyl or C1-C3 alkyl, and L is any ligand that does not contain oxygen; and exposing the substrate to a reducing gas to provide a film consisting essentially of nickel on the substrate surface.
Abstract:
A system for transferring real-time video data over a network comprises a video source, a video encoder for encoding and compressing video data supplied by the video source and a first network interface controller for transmitting compressed video data on the network. Furthermore a second network interface controller for receiving compressed video data from the network, a video decoder for decoding the video data received by the second network interface controller, and an image processor for processing and/or displaying the decoded video data from the video decoder are provided. The network controllers are configured for transmitting and receiving data in a continuous data stream which is synchronized with a clock signal and in a format which prescribes a pulse sequence of individual bit groups of which at least one is used for video data.
Abstract:
A communication system, network, interface, and port architecture are provided for transporting data across a network. The network can be arranged by connecting the ports in a daisy chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol. A first port forwards frames having a preemptive acknowledge field before the payload. A second port receives these frames, stores them in a frame buffer and modifies the preemptive acknowledge field according to its available frame buffer capacity. Said first port controls its data flow according to the modified preemptive acknowledge field.
Abstract:
A communication system, network interface, and communication port is provided for interconnecting a network of multimedia devices. The multimedia devices can send streaming and/or non-streaming data across the network. The network accommodates all such types of data and assigns data types to time slots or frame segments within each frame to ensure streaming data maintains its temporal relationship at the receiver consistent with the transmitter. A signaling byte is preferably used to keep track of an amount by which isochronous streaming data occupies a frame segment.
Abstract:
A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy-chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and nodes among the network can use a recovered clock from the bitstream to drive the transmitter and create a synchronous network even thought the network can receive Ethernet packets which are typically targeted for an asynchronous network. Non-compliant data, such as Ethernet data, can be sent as packets within a frame structure. The frame is synchronized to Ethernet coding violations used to signal the beginning of each frame, and each packet can be immediately followed by a packet coding violation. The frame and packet coding violations are represented as a sequence of 4B/5B codes that are not valid codes and, therefore, not present as Ethernet encoded data.
Abstract:
A communication system, network, interface, and port architecture are provided for transporting different types of data across a network. The network can be arranged by connecting the ports in a daisy chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol, and any incoming data that follows that protocol will be sent onto the network. If the incoming data protocol does not match the network protocol, then the incoming data is not sent immediately to the network, but instead is sent to an input pin of a device upon the network specifically designed to receive that incoming data. The network, therefore, has ports that support both compliant and non-compliant incoming data, and the devices that produce such data. Examples of non-compliant data include any data which does not time-division multiplex different asynchronous, isochronous, and synchronous data in dedicated channels within each frame, and which have a preamble, coding, frequency, or overall protocol different from that which is established for network transfer.
Abstract:
A method for obtaining diagnostic information about a region of a living being, the region having a medical device with a radiopaque portion disposed therein. An X-ray beam having a first energy level in excess of the K-absorption edge of the radiopaque portion of the medical device is directed at the region to obtain a first image information and radiographically locate the medical device within the living being and an X-ray beam having second energy level at or below the K-absorption edge is applied to the region to obtain a second image information.
Abstract:
A method for producing a S-nitrosylated species is provided. The method comprises: (a) providing a deoxygenated, alkaline aqueous solution comprising a thiol and a nitrite-bearing species; (b) acidifying the solution by adding acid to the solution while concurrently mixing the solution (e.g., by vigorously stirring the solution) to produce the S-nitrosylated species; and (c) isolating the S-nitrosylated species. The nitrite-bearing species can be, for example, an inorganic nitrite, such as an alkali metal nitrite, or an organic nitrite, such as an alkyl nitrite (e.g., ethyl nitrite, amyl nitrite, isobutyl nitrite or t-butyl nitrite). The thiol is preferably a thiol-containing polysaccharide, a thiol-containing lipoprotein, a thiol-containing amino acid or a thiol-containing protein, and more preferably a thiol-containing polysaccharide such as thiolated cyclodextrin. In many preferred embodiments, the S-nitrosylated species is insoluble in the acidified solution, precipitating upon formation. The S-nitrosylated species can be isolated, for example, by a process in which the precipitate is removed from the solution (e.g., by centrifugation) and the aqueous solvent remaining in the precipitate is sublimated (e.g., by freezing the precipitate and subjecting it to a vacuum). The isolated S-nitrosylated product is preferably protected from heat, light, moisture and oxygen.
Abstract:
This invention relates to devices and methods for the local, differential delivery of nitric oxide within the body. The devices include devices having at least two differing nitric oxide donor compounds, such as nitric oxide donor compounds having differing half-lives and nitric oxide donor compounds having different release mechanisms. The devices also include devices having at least two chemically distinct compositions to which nitric oxide donor compounds are adsorbed or attached or within which the donor compounds are disposed. The devices are typically used to increase local nitric oxide concentration in the body upon placement of the medical article at a delivery position on or within a patient. The methods of the present invention include a method of treating an atherosclerotic lesion which comprises: exposing the lesion to a first higher concentration of nitric oxide effective to reduce the number of cells within the lesion; and subsequently exposing the lesion to a second lower concentration of nitric oxide effective to inhibit restenosis. The methods of the present invention also include methods for preferentially providing differing nitric oxide donor compounds within different tissues to effect therapy.
