Abstract: A method for predicting clinical severity of a neurological disorder includes steps of: a) identifying, according to a magnetic resonance imaging (MRI) image of a brain, brain image regions each of which contains a respective portion of diffusion index values of a diffusion index, which results from image processing performed on the MRI image; b) for one of the brain image regions, calculating a characteristic parameter based on the respective portion of the diffusion index values; and c) calculating a severity score that represents the clinical severity of the neurological disorder of the brain based on the characteristic parameter of the one of the brain image regions via a prediction model associated with the neurological disorder.

Abstract: A level measuring device with an integratable lens has a radar level meter and an angle adjusting assembly. The radar level meter has a horn antenna and a lens antenna assembly mounted on a signal transceiving end of the radar level meter. The lens antenna assembly has a housing and a lens antenna. The housing is hollow and receives the horn antenna therein. One end of the housing is connected to the lens antenna, and the other end of the housing is connected to the signal transceiving end of the radar level meter. The angle adjustment assembly is mounted around the housing. As the lens antenna assembly covers the horn antenna, the horn antenna is less likely to be damaged. Additionally, the housing of the lens antenna assembly is connected with the angle adjusting assembly for angle adjustment of the combined horn antenna and lens antenna assembly.

Abstract: An FMCW radar level meter has an RF signal processing module, an intermediate frequency (IF) signal processing module, and a computation and display module. A signal generator of the RF signal processing module generates a first RF signal, which is radiated by an antenna to a measured object. The antenna received a second RF signal reflected by the measured object. The IF signal processing module processes the second RF signal and compares the first RF signal with the second RF signal. The computation and display module calculates and displays a distance between the FMCW radar level meter and the measured object. Using the RF signal processing module and the IF signal processing module to process the second RF signal, the issues of noise and temperature coefficient shift can be resolved.

Abstract: The present invention relates to a horn antenna device. The horn antenna device has a step-shaped signal feed-in apparatus and a conical horn antenna. The step-shaped signal feed-in apparatus has a stepped body having multiple stairs and a connecting pin. The stepped body is adapted to radiate electromagnetic waves and receive a reflection of the electromagnetic waves. According to the structure of the step-shaped signal feed-in apparatus of the invention, the resonating modes are easy to be determined. The directivity and the signal-to-noise rate are improved. In addition, the connecting pin is directly connected to the stairs for improving the signal stability of the horn antenna device.

Abstract: A measuring method for a frequency modulation continuous wave radar level meter is performed after presetting a previous-cycle weight and a current-cycle weight and acquiring a measured result in a previous cycle, and has steps of constantly transmitting a frequency modulation (FM) signal and receiving multiple reflected signals, obtaining a frequency difference between the FM signal and each reflected signal, selecting a characteristic frequency from a frequency spectrum, and calculating a measured result in the current cycle taken as the measured result in the previous cycle for calculating a measured result in a next cycle with a sum of a product of the measured result in the previous cycle and the previous-cycle weight and a product of a distance corresponding to the characteristic frequency so as to reduce variations of the measured result in each cycle and facilitate statistical analysis.
