    摘要: Improved reaction chamber designs are described that provide for improved control over the flow within the reaction chamber. The reaction chambers contain reactions for particle production from a flowing reactant stream. Improved reactant delivery nozzles are described that are useful for the delivery of gas/vapor reactants and/or aerosol reactants. Improved nozzle designs can result in more uniform reactant flow. Suitable reactors can comprise an electromagnetic radiation source that projects through the reactor to drive the reaction at an electromagnetic radiation reaction zone. The improved nozzle features are suitable for reactors for particle collection and/or for coating of substrates within the reaction chamber.

    摘要: A soft symbol decoder for use in a multiple input multiple output (MIMO) and OFDM (orthogonal frequency division multiplexing) system. The decoder generates soft symbol values for a digital signal that represents a number of source bits. The source bits are transmitted as symbols in corresponding to points in a signaling constellation. Soft metrics are determined by searching for all possible multi-dimensional symbols that could have been transmitted. The method includes transmitting a sample of the multi-dimensional symbol using K transmit antennas. The multi-dimensional symbol is represent-able as a complex, K-dimensional vector x. Each vector component of vector x represents a signal transmitted with one of the K transmit antennas. After transmission through a communication channel, a sample corresponding to the transmitted sample is received. The received sample is represented by a complex, N-dimensional vector y, where N is the number of receive antennas in the MIMO system. After the sample is received, a soft metric L(bi) is determined for each bit bi encoded by x according to the equation: L ⁡ ( b i ) = σ - 2 · ( min x j ❘ b i = - 1 ⁢  y - Hx j  2 - min x j ❘ b i = + 1 ⁢  y - Hx j  2 ) , , and xj represents all possible values for x. In addition, a reduced complexity method is used for providing soft metric values in the MIMO system. This exemplary aspect reduces the complexity of the above computations from 2BK to 2B(K−1), where B is the number of bits transmitted per symbol per antenna.

    摘要: A cache device is disposed on a connection path between a user computer executing a software application and a network. The application exchanges data with a further computer via the network. The cache device includes a cache memory and a processor. The cache device is configured to measure, by the processor, a first latency between the user computer and the further computer. The cache device is further configured to determine an acceptable latency range based on the latency and a requirement of the software application. The cache device is further configured to measure a second latency between the user computer and the further computer. The cache device is further configured to store, in the cache memory, a set of data transmitted from the user computer to the further computer, if the second latency is not within the acceptable latency range.
