Abstract: A microwave flowmeter and a flow rate measurement method are provided. The microwave flowmeter includes a transmitting circuit, a detecting circuit, and a computing unit. The transmitting circuit includes a substrate, a plurality of resonator elements, and a transmission line. Two ends of the transmission line receive high frequency electric feedings, so that the resonator elements separately generate corresponding microwaves and each of the microwaves has at least one resonant frequency. The detecting circuit detects offsets of the corresponding resonant frequencies that are caused when a fluid flows through the resonator elements, and records times at which the offsets happen. The computing unit is electrically connected to the detecting circuit, and computes a flow rate of the fluid according to the times at which the offsets happen of the resonant frequencies and locations that are of the resonator elements and that correspond to a flow path.
Abstract: A method for assessment of neural function by establishing an analysis module is revealed. The first step of the method is to capture images of the cultured cells with a plurality of fluorescence labeling by a fluorescence microscopy system for image analysis. The cultured cells include neurons and non-neuronal cells. Then select neurons with neurites having fluorescence labeling and exclude non-neuronal cells according to an area and a fluorescence intensity of nucleus. Also calculate an area of the neuronal cell body, a length of the neurites and a number of processes and branches to verify outgrowth of the neurites of the neurons. Next calculate a number of synaptic puncta having fluorescence labeling on the area of the neurites having fluorescence labeling defined in Step 2 to verify formation of the synaptic puncta of the neurons for assessment of neural function.

Abstract: The present invention relates to a method and an apparatus for measuring errors of a movable platform in multiple degrees of freedom. A light-source module disposed on a fixed platform emits light to a lens module disposed on a movable platform. The light is reflected to one or more optoelectronic sensing module on the fixed platform via the lenses of the lens module. Then a processing unit calculates an alignment error or/and one or more straightness error or/and one or more angle error of the movable platform according to the signal generated by the optoelectronic sensing module.
