Abstract: A machine-learning based VOC detection and identification method and an apparatus and system for implementing same.

Abstract: An embodiment of the invention provides a composition comprising a carbon material and an ionic liquid (IL), wherein the composition is configured to form a reactive oxygen species (ROS) in presence of oxygen and a radiation having wavelength in a range of about 150 nm to about 1100 nm. In another embodiment, the invention provides a method to generate ROS using the ionic liquid (IL) and the carbon material and the method to measure the same in situ.

Abstract: A vehicle-mounted terminal and a method for obtaining a resolution of a screen of a handheld terminal are disclosed. The method includes establishing a connection between a handheld terminal having a second screen and a vehicle-mounted terminal having a first screen, mapping a display of the second screen onto the first screen, obtaining a first coordinate difference between two coordinate points on the second screen and a second coordinate difference between two mapped points on the first screen that correspond to the two coordinate points respectively, and obtaining a resolution of the second screen using the relationship that a ratio of the first coordinate difference to the second coordinate difference is equal to a ratio of a mapped resolution of the second screen mapped onto the first screen to the resolution of the second screen, wherein the mapped resolution of the second screen mapped onto the first screen is a first resolution and the resolution of the second screen is a second resolution.

Abstract: The invention provides a system and method for effectively reducing peak-to-average power ratio (PAPR) in an OFDM signal. The method includes the steps of oversampling a signal in the time domain, gradually clipping an amplitude of the signal to a predefined level using a formula involving a hyperbolic tangent, bandpass filtering out-of-band spectral components of the signal due to non-linear clipping to be within a predetermined mask, and transmitting the signal.
