A magnetic dual glasses window structure includes a window blind, provided between two panes of glass, including tilt cords for supporting a plurality of slats and an operating system which includes a shaft attached to the tilt cords and a magnetic actuating device. The magnetic actuating device includes an actuating cord movably and encirclingly attaching to two end portions of the shaft, a pair of resilient elements attached to the actuating cord respectively for applying an urging force against the actuating cord, a magnetic seat connecting between the two resilient elements and positioned adjacent an inner surface of one of the panes of glass, and a magnetic slider positioned adjacent an outer surface of the pane of glass for magnetically driving the magnetic seat to move. Therefore, by sliding the magnetic slider, the actuating cord drives the shaft to rotate for controlling the tilt angle of each of the slats.

A manufacturing process of a construction strip includes the steps of (a) evenly mixing a predetermined amount of paint, talcum powder and volatile agent to form a plaster form coating mixture; (b) gradually passing an elongated strip body through an extrusion passage of an extrusion mold, wherein a uniform surrounding clearance between an interior wall of said extrusion passage and said strip body; (c) continuously injecting said coating mixture into said extrusion passage of said extrusion mold in order to fill said surrounding clearance, so that a uniform protective coating is evenly coated on said longitudinal surfaces of said strip body while said strip body is extruded from said extrusion mold; and (d) drying said protective coating to form a hard and durable protective coating shell integrally wrapped around said strip body.

The present invention provides a colorful coating material which consists essentially of a 10 to 40% of paint in weight, a 50 to 90% of talcum powder in weight and a 5 to 10% of volatile agent in weight. The paint, the talcum powder and the volatile agent are evenly mixed to form a plaster form coating mixture. The coating mixture is adapted for coating around an object by means of an extrusion mold to form a protective coating. When the protective coating is dried and solidified, a hard and durable protective coating shell is formed and wrapped around the object.

A quantification system is configured for debiasing media creative efficiency. In some embodiments, the quantification system leverages a weighted generalized linear model (GLM) to determine the individual impacts of media creatives beyond network effects. To prepare input data for fitting the weighted GLM, the quantification system analyzes spot airing data, creates a specific data structure for storing observations (e.g., network-media creative combinations) that can be provided to the weight GLM as input, and computes additional input data points needed by the weighted GLM (e.g., network spend, media creative efficiency per network-media creative combination, etc.). The weighted GLM is then fitted to obtain coefficients representing the individual impacts of the media creatives. The quantification system utilizes the computed impacts to adjust the previously computed media creative efficiency for each media creative. In this way, relative performance of media creatives can be objectively quantified across networks without needing digital evidence.
