A method of manufacturing a carbon-fiber pipe which is hollow and has a net shape, by knitting carbon fibers and general fibers, applying carbon or ceramic, and heating to burn the general fibers, and a carbon fiber heating lamp using the carbon-fiber pipe are provided. The multimodal profile may also include at least one identifier associated with the multimodal preference information. The polarity inversion mode of column inversion, formed by pixel voltage signal in technical solution makes white dot of damaged area of alignment film is more prominent during detection process, so it would be easy for the operator to recognize it and avoid the issue of missing detection. Such update operations are addition of a new set of map data, deletion of a certain set of map data, and replacement of a certain set of map data with a new set of map data. Broadcasts are then encrypted using the short-time key, wherein the user decrypts the broadcast message using the short-time key. The method fits a function having real and imaginary parameters to a number of transform coefficients to determine a best fit function within the signal analysis sample interval.
