Abstract: An embodiment apparatus for verifying a vehicle seat anti-pinch includes a base including a plurality of assembly holes, a seat mounting unit assembled to an upper portion of the base through the assembly holes, a seat mounted to an upper portion of the seat mounting unit, a support structure assembled at a rear of the seat mounting unit, and a measurement unit assembled to the upper portion of the base through the assembly holes, the measurement unit including a pressure measuring device movably mounted to a number of measuring points corresponding to main body parts of a passenger in a rear seat by the support structure, wherein the measurement unit is configured to measure a physical contact with the seat and a pressing force through the pressure measuring device.

Abstract: An optical gene biosensor is disclosed. The optical gene biosensor includes a substrate; a molecular beacon anchored to the substrate, wherein the molecular beacon includes an oligonucleotide specifically binding to a target nucleic acid molecule and a first compound bound to a first terminal of the oligonucleotide; an optical marker specifically binding to the first compound, wherein the optical marker is configured to retro-reflect irradiated light; a light source for irradiating the optical marker with light; and a light-receiver for receiving light retro-reflected from the optical marker. The optical gene biosensor may perform accurate quantitative analysis of a target nucleic acid molecule using both non-spectral and spectral light sources.

Abstract: Provided is a device for detecting a horizontal synchronization signal of an image forming apparatus. The device includes a light intensity converter to convert light intensity of a first beam emitted from a first light source and light intensity of a second beam emitted from a second light source to be different from each other, and outputting the first and second beams; a photo detector to receive the first beam and the second beam output from the light intensity converter, and outputting a first signal having a first level at a time of receiving the first beam and a second level at a time of receiving the second beam; and a horizontal synchronization signal detector to detect a horizontal synchronization signal of the first beam and a horizontal synchronization signal of the second beam by using the first signal.

Abstract: A light scanning unit includes a light source, a beam deflecting unit which reciprocatingly scans a light beam which is emitted from the light source to form an image sector and a first non-image sector and a second non-image sector disposed at opposite sides of the image sector, a sensor which senses the light beam which is deflected and scanned toward the first non-image sector, and a controller which adjusts a horizontal synchronization of the image sector which is formed by the light beam which is scanned in a first direction and a second direction which is the opposite direction to the first direction based on a time period of a signal which is outputted from the sensor.
