Techniques are disclosed for determining measurement uncertainty of and/or multipath effects on positioning measurements, based on the residual deviations between timing measurements and high-accuracy location results. An example method begins with collecting (510) a plurality of timing measurements or ranging measurements, or both, each measurement corresponding to at least one anchor node antenna having a known location. A measurement deviation is determined (520) for each measurement by comparing the measurement to a corresponding reference location. The measurement deviations are used (530) to estimate measurement quality for one or more subsequent positioning measurements, and/or uncertainty associated with one or more subsequent positioning estimates, and/or an effect of multipath on subsequent positioning measurements or estimates. In some embodiments, a covariance matrix is calculated from the measurement deviations and is used to determine statistical information or multipath effects for measurements corresponding to a particular one of the anchor node antennas.

A method and system for determining a position of a UE includes a first network node receiving a request for positioning information about the UE. The first network node requests a first positioning procedure at a first location node. The first location node determines using the first positioning procedure that involvement by a second location node is needed. The first location node initiates a trigger for positioning information about the UE to be sent to the second location node. The second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter, determines the position information of the UE by performing a second positioning procedure based on the environment measurement parameter, and sends a position calculation response with the positioning information.

The present invention relates to radio base station and to a related method for supporting positioning. The method includes measuring a relative time of arrival of two reference signals, where a first of the two reference signals is transmitted from a first neighboring radio base station. The method also includes transmitting the measured relative time of arrival to a positioning node, connected to the radio base station and the first neighboring radio base station.

The present invention relates to a system and method for reducing image artifacts for a CMOS camera used as an optical detector for a line confocal fluorescent imager. The method for reducing image artifacts in a monochromatic image comprises subtracting RGB channel offset mismatch; and correcting random row offset for each row. Preferably, the method also comprises correcting random column offset and gain. Optionally, the method also comprises clipping of defective pixels, and/or subtracting dark current. When the monochromatic image is a fluorescence image, the method also comprises a step of compressing CMOS camera noise. Also provided are a system for reducing image artifacts in a monochromatic image from a CMOS camera, as well as an image artifact reduction system for a CMOS camera-based line confocal fluorescent microscope.
摘要:
A cable arranging module suitable for an electronic device is provided. The electronic device includes a chassis and an electronic module disposed pluggably to the chassis. The cable arranging module includes a cable set, a fixed frame and a chain structure. The cable set is connected to the electronic module. The fixed frame is fixed in the chassis. The chain structure is connected between the fixed frame and the electronic module. The fixed frame and the chain structure form a chamber for containing the cable set. When the electronic module is located in the chassis, the chain structure is bended and contained in the chassis. When the electronic module is pulled out from the chassis, the chain structure drives the cable set to be curved and move. When the electronic module is pulled out entirely, the chain structure is extended and at least partially located out of the chassis.
