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 time-to-digital converter (TDC), a system-on-chip including a TDC, a method of phase detection for use in synthesizing a clock signal and a non-linearity corrector for a TDC. In one embodiment, the TDC includes a chain of delay elements configured to receive a clock signal and generate delayed clock signals. Each one of the delay elements includes: (1) a non-inverting buffer configured to delay the clock signal by about twice a delay of an inverter to provide a buffer-delayed clock signal and (2) a first transmission gate coupled to the non-inverting buffer and configured to delay the clock signal by about the delay of an inverter to provide a first gate-delayed clock signal.

Clinical grade vectors comprising transformed microflora vector having at least one transforming nucleic acid sequence containing at least one gene of interest are provided. The transforming nucleic acid encodes for a therapeutic polypeptide that is delivered to the host in need thereof topically, orally, intranasally and/or transderamally. The clinical grade vectors are derived from lactic acid bacteria, yeast and other non-pathogenic microorganisms and have been provided with selective/and or reporter genes that do not rely on antibiotic resistance. Moreover, the clinical grade vectors are provided with phenotypic and/or genotypic traits that limit the ex vivo dissemination of transforming nucleic acid sequence(s). Also provided are methods and compositions useful in treating diseases in animals.

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.
