Abstract: Disclosed is a photocatalyst filter module including: a housing having an inner space opened in a back-and-forth direction so that fluid passes therethrough; a partition for forming a plurality of photocatalyst accommodation spaces by partitioning the inner space; a photocatalytic ball accommodated in the photocatalyst accommodation space; a mesh-shaped cover unit attached to the front and the rear of the housing to prevent the photocatalytic ball from being separated; and a light source unit provided adjacent to the rear of the housing.

Abstract: A micromagnetometry system for detecting the presence of very small quantities of magnetic particles comprises a first magnetic hybrid AMR/PHR multiring sensor using a Wheastone bridge electrical configuration, a first current source, a first voltage measurement device, a set of at least one magnetic particles deposited on the first magnetic sensor and a processing unit for detecting from a set of different measured differential voltages a magnetic flux shift representative of the presence of a least one deposited magnetic particle. The micromagnetometry system comprises means for creating a magnetic excitation field HAC to make produce by each motionless magnetic particle a stray magnetic field oscillating along the time at a constant frequency ? ranging from 10 Hz to 3 KHz.

Abstract: A multi-resonant broadband antenna constructed with a dielectric substrate; a fractal radiation element having a predetermined fractal grid structure adhered on an upper surface of the dielectric substrate. A feed line adhered on the upper surface of the dielectric substrate feeds the fractal radiation element, and a ground plane positioned on a lower surface of the dielectric substrate opposite to the feed line, is physically separated by the dielectric substrate from the feed line.
