    Abstract: Disclosed are an ultrasonic medium supplying jig and a fast ultrasonic scanning apparatus with a circulating medium, in which the medium is continuously supplied to between an ultrasonic probe and a to-be-scanned object to prevent the to-be-scanned object from being submerged in water, thereby enabling a stable ultrasound image to be obtained while achieving fast scanning. The disclosed ultrasonic medium supplying jig may include jig for supplying an ultrasonic medium, the medium supplying jig including: a main body having a space provided to open at least one surface thereof to form a receiving part in which one end including a sensing surface of an ultrasonic probe is received; a medium inlet port through which the ultrasonic medium is injected; a first medium outlet port provided at a position of the main body, where a sensing surface of the ultrasonic probe is disposed, to supply the ultrasonic medium; and a medium supply line provided to transfer the ultrasonic medium by connecting the medium inlet port with the first medium outlet port; and a second medium outlet port being in communication with the medium supply line and formed on the outer surface of the main body while penetrating a bottom surface of the main body from the first medium outlet port.

    Abstract: Disclosed are a sensitivity analyzing device using a frequency response and a sensitivity analyzing method using the same. The device includes a vibration exciter configured to configure a vibration exciting pattern and apply a physical force to one face of a test object based on the vibration exciting pattern; a first sensor in contact with the one face of the test object to measure a physical force applied to the test object by the vibration exciter; a second sensor in contact with an opposite face of the test object to the one face to collect a vibration of the test object caused by the physical force; and a sensitivity analyzer configured to: control the vibration exciter to configure the vibration exciting pattern; convert the physical force signal measured by the first sensor and the vibration signal collected by the second sensor in responses to the vibration exciting pattern into frequency domain signals to calculate a frequency response function of the test object; and calculate a sensitivity index of the test object to a variation in a physical external force, based on the frequency response function.

    Abstract: A lighthouse lantern comprising a power supply and a phosphor-containing emitter is disclosed. The lighthouse lantern includes a power supply; a laser diode configured for receiving power from the power supply and irradiating laser in one direction; a phosphor-containing emitter positioned on a traveling line of the laser, wherein the emitter is configured for receiving the laser and emitting light; and a pair of reflective structures disposed symmetrically with respect to the phosphor-containing emitter, wherein each reflective structure has a reflective surface inclined in a direction away from the phosphor-containing emitter, wherein the reflective surfaces of the reflective structures are symmetrical with each other with respect to the phosphor-containing emitter. In accordance with the present disclosure, the lighthouse lantern may generate high output with low input power and thus has improved power efficiency, may suppress frequent failures near sea or seawater, and may reduce production costs.
