The pothole sign detection system includes an electromagnetic wave transmitting unit, an electromagnetic wave receiving unit, an electromagnetic wave receiving unit, a dielectric constant calculation unit, a crack rate diagnosis unit, a pavement layer separation state diagnosis unit, an attenuation calculation unit, a pavement layer inside state diagnosis unit, and a pothole sign detection unit.

Abstract: The present invention relates to a method for manufacturing a module type microfluidic chip comprising: (a) printing electrode patterns on a substrate using a conductive ink and inkjet printing; (b) cutting the printed electrode patterns; and (c) assembling the cut electrode patterns to manufacture the module type microfluidic paper chip. Unlike the traditional method for manufacturing printed circuit substrate using a patterning agent or device, the method of the present invention only incorporates a simple printing process using an inkjet printer, and thus patterning can be simplified and various types of chips can be manufactured depending on the assembly type of electrode patterns. Accordingly, inexpensive, economical, and highly utilizable microfluidic chips can be provided using the method of the present invention.

Abstract: A compensation pendulous accelerometer comprises a body in which a pendulous unit is positioned that is made as a unitary plate of a silicon monocrystal and comprises a movable vane on a flexible suspension and a support frame with protrusions. Two magnetic systems are secured on opposite sides of the movable vane and two coils of a torquer are positioned in a clearance of a corresponding core and are secured on a corresponding side of the movable vane. The flexible suspension includes flexible members arranged at an angle of 90 degrees relative to one another, symmetrically relative to an axis of symmetry of the pendulous unit. When the accelerometer is accelerated, the movable vane deflects in the opposite direction of the acceleration, and a current in the coils returns the movable vane to its initial position. A measured amount of current through coils is used to determine the acceleration.
