摘要:
The present invention relates to a system for the 3-D monitoring and analysis of motion-related behavior of test subjects. The system comprises an actual camera, at least one virtual camera, a computer connected to the actual camera.and the computer is preferably installed with software capable of capturing the stereo images associated with the 3-D motion-related behavior of test subjects as well as processing these acquired image frames for the 3-D motion parameters of the subjects. The system of the invention comprises hardware components as well as software components. The hardware components preferably comprise a hardware setup or configuration, a hardware-based noise elimination component, an automatic calibration device component, and a lab animal container component. The software components preferably comprise a software-based noise elimination component, a basic calibration component, an extended calibration component, a linear epipolar structure derivation component, a non-linear epipolar structure derivation component, an image segmentation component, an image correspondence detection component, a 3-D motion tracking component, a software-based target identification and tagging component, a 3-D reconstruction component, and a data post-processing component. In a particularly preferred embodiment, the actual camera is a digital video camera, the virtual camera is the reflection of the actual camera in a planar reflective mirror. Therefore, the preferred system is a catadioptric stereo computer vision system.

This invention relates to a system and the methods of making custom footwear. A multi-level customization process is employed in the system of the invention. First, shoe last is customized according to the biometric features of the foot.Secondly, the components of the footwear are fine-tuned through a set of interactive measurements for the wearer' needs, while the appearance of the footwear is custom-designed according to the taste of the wearer. Major components of the custom footwear include a custom upper that best-fits the shape of wearer's foot, a multi-layered custom insole with its surface conforming to the plantar surface of the foot, and a custom sole that sandwiching a heel pad with custom height.

The present invention provides novel methods for isolating rat embryo-derived cells and modifying the genome of the rat cells which typically comprise the steps of: constructing a DNA molecule in which desired sequence modifications are contained in a segment of DNA (a "targeting DNA); introducing the targeting DNA construct into the cell (e.g., by microinjection, electroporation, transfection, or calcium phosphate precipitation); and selecting cells in which the desired sequence modifications have been introduced into the genome via homologous recombination.

The invention provides for improved multi-well plates and platforms that comprise a plurality of wells having increased volume capacity and clustered in a standard multi-well plate format and dimensions, said multi-well plate format being compatible with auxiliary equipment currently used and designed for the particular multi-well plate format. More particularly, the invention provides improved multi-well plates comprising a base to improve wells having one or more said wells having rectangular configuration, better retention of working materials and tissue culture ingredients than observed in conventional round-shaped wells. A cover is provided for protecting the assembly and cell cultures.
摘要:
The present disclosure provides methods for generating embryonic stem cell lines with the integration of a site-specific recombinase deriving from recombinase mouse models. Utilizing methods of the present disclosure, targeting vectors including selection cassettes flanked by respective recognition sites may be removed in ES cells and thus resulting progeny o chimeras would have absence of the selection cassette.
