The present invention provides an image processing method for CDSEM for determining a measuring range of an image of a target pattern measured by a CDSEM machine. The image processing method of CDSEM comprises: obtaining a first gray scale image based on the image of the target pattern; performing Fourier transform to the first gray scale image to obtain a first frequency spectrum distribution; filtering out frequency spectrum components whose absolute values of ordinate are greater than preset threshold in the first frequency spectrum distribution to obtain a second frequency spectrum distribution, the preset threshold relates to the background noise and the signal frequency of SRAF features; and determining the measuring range based on the second frequency spectrum distribution.

Image processing method and device for CDSEM

An ultrasound fetal imaging system uses an acceleration sensor () for generating an acceleration signal relating to movement of the ultrasound transducer (). A user is guided in how or where to move the ultrasound transducer based on the results of image processing of the ultrasound images. The user can thus be guided to move the transducer in a certain direction so as to achieve a complete scan of a fetus in a shortest possible time. This limits exposure of the expectant mother to the ultrasound energy. The fetal image obtained may be used to determine a fetal weight, for example using regression analysis based on some of the parameters derived from the obtained image.

Fetal imaging system and method

Disclosed is a hardware-based protection group switching method and optical communication equipment. The method includes: transmitting, by a FPGA in equipment when detecting switching triggering information indicating that a local network element possibly has switching triggering situations, the switching triggering information to each protection state machine through a hardware bus; determining, by each protection state machine according to related traffic flow information, one or more related protection groups that are possibly affected by each switching triggering situation, and generating each corresponding switching triggering condition according to each piece of switching triggering information; separately querying, by the protection state machines corresponding to the related protection groups, a pre-stored table for APS protocol operation results; and updating a cross connection table according to the operation results, and configuring the updated cross connection table to a cross connection chip or a packet switching chip through the FPGA.

A system and method is provided for monitoring the fetal position and/or orientation of the fetus of an expectant mother. An acoustic sensor array is positioned over the belly. The pattern of acoustic sensor signals is processed to determine a fetal orientation and/or to determine movement over time of the fetus.

Fetal monitoring system and method

A system for monitoring the fetal size of an expectant mother comprises an acoustic sensor for positioning over the belly of the expectant mother, the acoustic sensor configured to receive an acoustic signal generated by the fetal heartbeat and to generate a sensor output signal. A fetal size is determined from a sensor output signal strength. This system is based on the realization that certain acoustic signals generated by the fetal heart beat are strongly correlated with the fetus size.

The invention discloses a method and a receiving device of the Viterbi algorithm. The method is applicable for a Viterbi decoder that receives an output signal generated by a convolution code encoder processing an original signal. The convolution code encoder includes M registers and M is a positive integer greater than or equal to 2. The method includes the following steps. First, for the first to the Mth data of the output signal, the Viterbi decoder performs the add-compare-select operation based on the known M initial values of the M registers. Then, for the Mth-last to the last data of the output signal, the Viterbi decoder performs the add-compare-select operation based on the known last M bits values of the original signal, thereby reducing the computational complexity of the add-compare-select unit.
