  • Publication number: 20190247594
    Abstract: An apparatus suitable for pressurized liquid transfusion is disclosed. The apparatus includes a nozzle assembly enclosed by the combination of a casing and a check nut. The nozzle assembly includes an elastomeric ring and a nozzle received by the combination of a cap and a receptacle. The elastomeric ring surrounds the nozzle and a proper seal is created therebetween. The dimension of the internal contour of the elastomeric ring is a bit smaller than the nozzle. The elastomeric ring is stretched so as to receive the nozzle. Additional processing may be applied to the elastomeric ring to achieve a different type of proper seal. Pressurized liquid passes through the apparatus so as to be transfused. The aforementioned seal serves to avoid leakage or pressure loss at the apparatus so as to avoid undesired aerosolization effects of an aerosolizer the apparatus is installed in.

  • Patent number: 7225306
    Abstract: An efficient way to generate the address sequence for the RAM implementation of Forney's (P, D, m) interleavers requires only A+1+2P memory locations, which is close to the theoretical minimum. Here A is the average delay of the symbols through the interleaver. The address generation circuit (with simple adders and registers) works for variable P,D,m. This is achieved by decomposing the (P,D,m) interleaver into a concatenation of a multiplexed interleaver (implemented with A+1 memory locations), followed by a block interleaver (implemented with 2P memory locations). In many applications, these 2P memory locations can be treated as part of the memory for controlling the data flow of the system.

  • Publication number: 20050286566
    Abstract: The present invention provides a system for mitigating impulse noise effects in a digital data transmission system, particularly in a DSL-based communications system (300), by optimizing error correction systems with an erasure forecasting scheme. Within the communications system, encoding and structuring constructs form and permute data transmission units for transmission in a deterministic manner (i.e., having known, fixed characteristics). Once data transmission units have been received over a transmission channel, de-structuring and decoding constructs inversely permute and decode those data transmission units, according to the deterministic manner. Data decoding is monitored (302), and the occurrence of an impulse noise event in the transmission channel is identified (304). A first data transmission unit affected by the impulse noise event is decoded (306).

  • Patent number: 6571228
    Abstract: A method uses a hybrid neural network including a self organizing mapping neural network (SOM NN) and a, back-propagation neural network (BP NN) for color identification. In the method the red, green and blue (RGB) of color samples are input as features of training samples and are automatically classified by way of SOM NN. Afterwards, the outcomes of SOM NN are respectively delivered to various BP NN for further learning; and the map relationship of the input and the output defines the X,Y, Z corresponding the x, y and z values of a coordinate system of the standard color samples of RGB and IT8. By way of the above learning structure, a non-linear model of color identification can be set up. After color samples are self organized and classified by SOM NN network, data can be categorized in clusters as a result of characteristic difference thereof.

  • Patent number: 5838667
    Abstract: A method of coordinating very high speed bi-directional data transmissions between a central unit and a plurality of remote units over distinct twisted pair transmission lines that share a binder is described. Specifically, periodic synchronized upstream and downstream communication periods are provided that do not overlap with one another. The upstream and downstream communication periods for all of the wires that share a binder are synchronized. With this arrangement, all of the very high speed transmissions within the same binder are synchronized and time division duplexed such that downstream communications are not transmitted at times that overlap with the transmission of upstream communications. In some embodiments, quiet periods are provided to separate the upstream and downstream communication periods. The described invention may be used in conjunction with a wide variety of modulation schemes, including both multi-carrier and single carrier transmission schemes.
