摘要:
Disclosed is a method of preparing ZnO nanopowder according to a non-equilibrium synthetic process, comprising adding an organic substance containing an amine group or a carboxyl group as a fuel material to an aqueous solution having Zn2+ and (NO3) ions to prepare a mixed solution, and heating the resulting solution with agitation. The method is advantageous in that the ZnO nanopowder has excellent valuable metal recovery and harmful organic substance decomposition efficiency, and the highly pure ZnO nanopowder with nano-sized particles is prepared in commercial quantities.

In embodiments of the present invention, systems and methods of remotely monitoring a plurality of individuals may include providing a plurality of monitoring objects, wherein each monitoring object is associated with the environment of one of the plurality of individuals. A sensor may be integrated into each monitoring object, wherein the sensor collects activity data for the individual associated with the monitoring object. The sensor data may be processed at each monitoring object to obtain monitoring information for the activity of the individual associated with the monitoring object. The monitoring information obtained with each monitoring object may be transmitted over a network to a receiving object, wherein the receiving object may display a picture associated with the particular individual being monitored at the time that it displays information about that individual.

A shaking sensing unit includes a sensor sensing a rotation about at least one axis, a high pass filter passing only a signal having a frequency not less than a cutoff frequency of the high pass filter, among electrical signals output from the sensor, and a low pass filter passing only a signal having a frequency not greater than a cutoff frequency of the low pass filter and higher than the cutoff frequency of the high pass filter, among the electrical signals output from the sensor. The cutoff frequency of the high pass filter and the cutoff frequency of the low pass filter are variably determined according to a shaking frequency.

A battery powered, low voltage faucet flow timer, water usage calculator, and energy consumption awareness meter is simple to install and calibrate and may enable a user to understand the water usage associated with showering, bathing or other open faucet water use activity. The device may provide a simple method for calculating the flow characteristics for a shower, bath or other faucet and entering this flow rate into the timing device so that the timer provides an accurate calculation of water usage indicating both the time spent with the water running and approximate total water usage.

In one embodiment, the invention relates to an apparatus and method for recording/reproducing at least one text subtitle stream. The method includes receiving at least one text subtitle stream from an external source, each text subtitle stream including a style segment defining at least one region style and at least one presentation segment, each presentation segment containing at least one region of text and being linked to at least one region style, wherein the style segment including a player style flag which indicates whether a player is permitted to generate its own player style. Thereafter, the method calls for decoding the text subtitle stream using the style segment defining at least one region style and a player style flag.

In one embodiment, a first play list is generated if a first additional data stream is provided, and a second play list is generated if a second additional data stream is provided. The first play list links the main video data stream with the first additional data stream such that the main video data stream is reproduced with the first additional data stream if the first play list is reproduced. The second play list links the main video data stream with the second additional data stream such that the main video data stream is reproduced with the second additional data stream if the second play list is reproduced.
