  • Patent number: 11247154
    Abstract: Filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control. Flat, concave, convex, asymmetric concave and asymmetric convex outlet inserts have pluralities of fluid bores with varying orientations to permit enhanced fluid flow control out of the filter capsules including divergent, convergent and mixed divergent/convergent fluid flows. An inlet with an axis offset at an angle to the longitudinal axis of the filter capsule body permits user control over the fluid flow strike point in a sink or shower stall via rotation of the capsule about the inlet connection point. A recessed outlet improves the prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant sources.

  • Publication number: 20150196879
    Abstract: A process for producing a porous metal membrane (pore size 10 nm and 1 um), a metal membrane of this type, the use of the metal membrane and also corresponding filter modules. The Dice is 1-20 microns. The plasma immersion ion implantation process is utilized by bombarding a very thin metal foil with noble gas ions accelerated by means of a first accelerating voltage, in particular from both sides. The ion current is selected so that supersaturation occurs in the metal foil. Pores, in particular under the metal surface, are then formed by bubble segregation after supersaturation. Opening of the pores formed under the metal surface by ion implantation is effected by atomization of the surface by means of bombardment with noble gas ions using a second accelerating voltage which is lower than the first accelerating voltage.

  • Publication number: 20070268976
    Abstract: A method and a receiver system for subcarrier-specific frequency offset correction including frequency offset estimation, updating and compensation. The method includes initial frequency offset estimation in time domain using packet preamble, frequency offset compensation during channel estimation symbols using the initial frequency offset estimate, and frequency offset update tracking during header and data part both being performed in the frequency domain. The initial frequency offset estimation includes using a sum over a number of time lagged autocorrelation results, corresponding to a number of the last consecutive symbols of the preamble part of the packet with the autocorrelations being the result of a sum over a window of cross-correlations between the incoming signal and the respective packet synchronization sequence.

  • Publication number: 20070067704
    Abstract: Pairs of parallel Viterbi decoders use windowed block data for decoding data at rates above 320 Mbps. Memory banks of the deinterleavers feeding the decoders operate such that some are receiving data while others are sending data to the decoders. Parallel input streams to every pair of decoders overlap for several traceback lengths of the decoder causing data input to a first decoder at the end of an input stream to be the same as the data input to a second decoder of the same pair at the beginning of an input stream. Then, the first decoder is able to post-synchronize its path metric with the second decoder and the second decoder is able to pre-synchronize its path metric with the first. Either, the deinterleaver data length is an integer multiple of the traceback length or the data input to only the first block of the first interleaver is padded.

  • Publication number: 20070064744
    Abstract: Frame synchronization methods and systems suited for packet communications systems, and particularly time frequency hopping packet communication systems, are disclosed. Frame synchronization is performed by performing a first correlation on information of received symbols and performing a second correlation on results of the first correlation. In systems with repeating synchronization information modulated by a cover sequence, the results of the second correlation may be used to determine symbol numbering of symbols in a packet.

  • Publication number: 20070058739
    Abstract: An automatic gain control method and system for use in signal processing of OFDM symbols at a receiver. Two stages of coarse and fine automatic gain control are implemented that adjust different gains in an analog RF processing stage of the receiver. Gain of a low noise amplifier and a mixer are adjusted during a first and coarse automatic gain control stage based on feedback from a digital baseband stage. During a subsequent fine gain control period, the gain of a programmable gain amplifier is adjusted separately for each frequency band used by the OFDM symbols based on a histogram bin that counts the number of output samples of an analog to digital converter whose magnitude falls within certain ranges. Coarse and fine gains are updated after each OFDM symbol.

  • Publication number: 20070058693
    Abstract: A method and system for removing frequencies interfering with a UWB OFDM receiver from transmission frequencies of the UWB communication. A sensing mechanism is added to the receiver that develops an energy histogram for the frequencies in a received signal and develops a tone mask for masking the interfering frequencies. The tone mask is applied after a mapping stage in the transmitter of the UWB communication and removes the interfering frequencies from the transmitted signal. Various criteria based on energy averaging are used to identify and null and remove the interfering frequencies.

  • Publication number: 20070058738
    Abstract: A method and system for estimating DC offset and removing the excess DC offset from samples used by an overlap-and-add operation at the receiver of OFDM symbols in UWB communication. The DC offset for each sample within the overlap-and-add interval may be estimated using a sliding window, of the size required for an FFT, operation over past samples. The DC offset may be estimated for a sample within the overlap-and-add interval and updated for the succeeding samples. A size of the overlap-and-add interval may be fixed or may be allowed to vary according to switching characteristics of an analog RF stage preceding the overlap-and-add operation.

    Abstract: A method for determining antenna usage in a multiple input multiple output (MIMO) wireless communication system. The method includes exchanging information between terminals concerning the number of transmit antennas and number of receive antennas. In some embodiments antenna usage is based on the number of transmit antennas, the number of receive antennas, and an indication of channel quality. In some embodiments less than all of the available antennas, particularly transmit antennas, are used at a given time, with unused transmit antennas varying over time.
