摘要： A plurality of monitoring devices are arranged at different heights and steps, and infrared reflective assemblies of the monitoring device are set at different heights to collect infrared spectral data of chemical constituents of the air mass that are being diffused in airspace of different heights. The pollution factors contained in the air mass and the pollution level of each factor are learned by using IR spectrum for qualitative and quantitative analysis on the pollution factor, therefore realizing continuous monitoring in a certain area. Artificial duty is not required while 24-hour continuous intelligent monitoring can be achieved. Besides, meteorological data are collected in combination with the meteorological data collected by the meteorological information acquisition module at different heights and calculation is made based on the air diffusion model of various pollution factors to finally determine the position of air pollution source.

摘要： Methods, apparatuses, and systems are presented for switching between channels of encoded media data involving receiving encoded media data including reference frames and dependent frames for a plurality of channels, wherein each dependent frame refers to at least one reference frame. Frames associated with a first channel from the plurality of channels are decoded to generate a decoded signal for the first channel. While decoding frames associated with the first channel, data corresponding to at least one reference frame associated with a second channel from the plurality of channels are stored. In response to a control signal for switching from the first to the second channel, at least one dependent frame associated with the second channel is decoded by utilizing the stored data corresponding to the at least one reference frame associated with the second channel, to generate a decoded signal for the second channel.

摘要： A Ku-band integrated pre-distortion type linearizer bridge circuit for use in linearizing the performance of a traveling wave tube amplifier. The linearizer bridge circuit comprises linearizer bridge that embodies a phase shifter and a fixed delay in a linear arm, and a Schottky diode distortion generator and a PIN diode attenuator in a nonlinear arm. The output of the linearizer bridge is coupled through an output amplifier and an output attenuator. The RF output signal from the linearizer bridge circuit is coupled to the traveling wave tube amplifier. A control circuit is coupled to the phase shifter, the nonlinear Schottky diode distortion generator circuit, and the PIN diode attenuator, and receives on and off input command signals, and outputs a bilevel telemetry signal that is used as a mode indicator for ground command control. The control circuit is used to adjust settings of the Schottky diode distortion generator, the phase shifter, the PIN diode attenuator, and adjust the gain and attenuation settings of the output amplifier and output attenuator. All circuits of the linearizer bridge circuit are integrated onto a single alumina substrate.
