摘要:
A method includes concurrently exciting neighboring pairs of transducer elements of an array for at least two transmits, wherein the array has a focus in a range of ten to twenty centimeters with a f-number of five or less. The method further includes receiving first echoes with individual transducer elements of a first sub-set of the transducer elements for a first of the at least two transmits, and receiving second echoes with individual transducer elements of a second sub-set of the transducer elements for a second of the at least two transmits. The method further includes extracting second harmonics from the echoes of the at least two transmits. The method further includes beamforming the extracted second harmonics. The method further includes generating an image based on the beamformed extracted second harmonics.

An ultrasound imaging system includes a beamformer (104) configured to beamform ultrasound signals. The beamformer includes input/output (110) configured to at least receive ultrasound signals. The ultrasound imaging system further includes a first ultrasound probe connector (128) and a second ultrasound probe connector (128). The ultrasound imaging system further includes a switch (134) that concurrently routes ultrasound signals concurrently received via the first ultrasound probe connector and the second ultrasound probe connector to the beamformer, which processes the ultrasound signals.
摘要:
A method for quantitative characterization of non-covalent interactions and analyte quantification in nanoliter samples is described. The procedure is based on Flow Induced Dispersion Analysis (FIDA), of which the only system requirements is a narrow tube, capillary or channel equipped with a detector. The technique can be implemented using standard equipment such as High Performance Liquid Chromatography (HPLC), Flow Injection Analysis (FIA) or Capillary Electrophoresis (CE).
摘要:
A method and system for packet synchronization may comprise receiving a plurality of bits from an incoming sample of data. The received plurality of bits may be sliced at a first sampling rate. A logic level of at least one of the received plurality of bits may be determined based on the slicing of the received plurality of bits. The received plurality of bits may be synchronized with a channel access code based on determining the logic level of at least one of the received plurality of bits. The channel access code may be sampled at a higher frequency, to increase the probability of detecting whether the incoming bit is LOGIC 1 or LOGIC 0.

摘要:
The invention relates to a method of manufacturing a product having a sub-micron primary particle such as metal oxide, metal oxidhydroxide or metal hydroxide product, said method comprising the steps of: introducing a solid reactor filling material in a reactor, introducing a metal-containing precursor in said reactor, introducing a co-solvent into the said reactor, introducing a supercritical solvent in the said reactor. By these steps a contact between the metal-containing precursor and the co-solvent is established, thus resulting in the formation of said product in the proximity of the said solid reactor filling material. The present invention offers the astonishing possibility of producing anatase phase of TiO2 at temperatures as low as between 50° C. and 100° C. and at concurrent pressures of 100-200 bar. The invention also relates to a product such as anatase TiO2 produced by the method and also relates to an apparatus utilising the method.

This invention relates to the treatment of a prepared food product or an intermediate product for a prepared food product having a reduced content of species and a product hereof. In particular the method relates to a method of producing healthier and tastier food products without losing the mechanical integrity of such products. The method involves post-processing of prepared foods by at least one treatment by a fluid at supercritical conditions, and generally results in products having a reduced fat content and/or reduced content of other species.
摘要:
Aspects of a method and system for closed loop power control in wireless systems are provided. In this regard, an output power of an amplifier may be measured and an indication of the measured power may be compared to a reference signal. The results of the comparison are utilized to generate an error correction factor. The gain of a preamplifier may be adjusted utilizing the error correction factor, where the output of the preamplifier may be input to the amplifier. The error correction factor may be generated via a proportional integral derivative controller. The gain of the preamplifier may be adjusted via at least one control signal, where the at least one control signal may be generated based on a reference control word and the error correction factor. The indication of the measured power and the reference signal may be time aligned.
