The present invention provides a method and apparatus for decoding two-channel matrix encoded audio (32) to reconstruct multichannel audio (34) that more closely approximates a discrete surround-sound presentation. This is accomplished by subband filtering (54) the two-channel matrix encoded audio, mapping (70) each of the subband signals into an expanded sound field (68) to produce multichannel subband signals, and synthesizing (78) those subband signals to reconstruct multichannel audio. By steering the subbands separately about an expanded sound field, various sounds can be simultaneously positioned about the sound field at different points allowing for more accurate placement and more distinct definition of each sound element.

The present invention relates generally to a magnet motor, and having being provided the driven power of the electromagnet motor for electric vehicles, wherein, it has provided with a wireless coil whole rotator, which the upper part has been constructed with an equal angle, a power perpetual magnet is provided. At least one set of a magnet pole coil is formed into an electromagnet pole module and a circuit control unit. Using the perpetual magnet and the less electricity consumption of an electric magnet pole generates the repelling torque, accomplishing the object of the turning rotator to generate power. Either it is coupled with a simple or a complex structure; it can apply to be the driven motor of a bicycle, a motorcycle and a car. Moreover, it can greatly reduce the consumption of the vehicle battery electricity, and make it to be an environmental protection and practical vehicle means.

The method of positioning a Doppler ultrasound transducer for performing blood flow measurement according to the invention comprises the steps of: detecting a pressure oscillation signal from an inflated cuff placed on patient's artery; detecting an ultrasound pulse signal from the Doppler ultrasound transducer placed along the artery; deriving a first signal from the pressure oscillation signal and the ultrasound pulse signal, the first signal indicating the degree of synchronization between the pressure oscillation signal and the ultrasound pulse signal; and outputting an indication signal to indicate the Doppler ultrasound transducer is in a desired position when the first signal satisfies a predefined condition. Since the synchronization property of the cuff pressure oscillation signal and the ultrasound signal caused by the blood flow is utilized to determine whether the transducer is well positioned or not, ultrasound signal, which is a pulse signal but not reflecting the blood flow of the artery, could be determined as not in synchronization with the oscillation signal and therefore the accuracy of the positioning could be improved.

Magnetoelectronic components comprise at least one oblong working structure made of a ferromagnetic material, along which magnetic domain walls can migrate, means for applying an electric current to this working structure, and at least one magnetic field sensor for the magnetic field generated by the working structure. The working structure is designed so that it is able to form domain walls, the transverse magnetization direction of which in the center has no preferred direction in the plane perpendicular to the migration direction thereof along the working structure, and/or can form massless domain walls. It was found that the kinetic energy of such moving domain walls vanishes. These walls are thus not subject to the Walker limit nor to intrinsic pinning. As a result, the components can read, store or process and finally output information more quickly. The invention also relates to a method for measuring the non-adiabatic spin transfer parameter β of a ferromagnetic material. This method was developed as part of a more in-depth examination of the phenomena that were found.

A method for intracellular delivery of single proteins or other cargo molecules by encapsulation within nanocapsules formed by interfacial polymerization of one or more types of monomers and selected protease cleavable cross-linkers is provided. The thin positively charged capsules are readily brought into the cytosol of target cells by endocytosis. The capsules are degraded by the action of endogenous proteases or co-delivered proteases on the cross-linkers releasing the functional cargo unaltered. The cross-linkers can be adapted to be cleavable by specific enzymes selected from available intracellular enzymes within the target cell or co-delivered or self-cleaving when the cargo itself is a protease. The nanocapsules produced by the methods have been shown to have long-term stability, high cell penetration capability, low toxicity and efficient protease-modulated specific degradability without affecting cargo protein function.

This invention relates to a method and device for calibrating the offset of an imaging system. The core idea of the invention is to place a reference object in the measurement chamber of the imaging system, measure the signals associated with the reference object at different points of time, calculate the merit function based on changes of the parameters representing the electromagnetic property of the reference object, and derive an optimal set of offset data that minimizes the value of the merit function for compensating the offset of the system in subsequent image reconstructions. In one embodiment, the invention uses a reference object comprising a non-conductive envelope and a cavity which can be filled with a conductive fluid and emptied, and in this way reduces the imaging interference caused by the reference object during monitoring.

Techniques to enable efficient operation of co-located WLAN and Bluetooth devices are described. A station (e.g., a cellular phone or a laptop computer) determines the activity of a Bluetooth device and ascertains idle periods of the Bluetooth device. The station communicates with an access point in a WLAN during the idle periods of the Bluetooth device. The station may operate in a power save mode with the access point, send a poll frame to the access point during an idle period, and retrieve the buffered data from the access point during the idle period. The station may also operate in an unscheduled APSD mode with the access point, send a trigger frame to the access point during an idle period to start a service period, and exchange data with the access point during the service period.

There is disclosed a normal-pressure plasma-based apparatus for processing waste water by mixing the waste water with working gas. The apparatus includes a waste water supply, a gas supply, a plasma-based processing unit connected to both of the waste water supply and the gas supply, a reservoir connected to the plasma-based processing unit and a washing tower connected to both of the reservoir and the plasma-based processing unit. The plasma-based processing unit and the washing tower are used together to mix the waste water with the working gas at least twice. The plasma-based processing unit produces active substances to decompose organic compounds and eliminate the colors of the organic compounds. Thus, performance in processing the waste water is excellent while the consumption of time and energy is low.
