The multifunctional radiant heat plate includes a heat conductive plate, a first and second composite sheet, at least one electroconductive metal layer, and electrodes. The heat conductive plate may be sandwiched between the first and second composite sheets. The at least one electroconductive metal layer is stacked on the composite sheet. Electrodes may be connected to the heat conductive plate and the metal layer, respectively. According to the disclosure, the heat conductive plate, the composite sheet, the electroconductive metal layer, and the electrodes are radiant heat interfacial components disposed between battery cells, and the composite sheet includes a piezoelectric material and a heat conductive filler dispersed and filled in a matrix resin.

Abstract: Disclosed is an integrated measurement apparatus that may perform measurement of various material characteristics (e.g., thermal conductivity, electrical conductivity, magnetic inductivity, etc.) and defects of a composite material in a non-destructive manner. The apparatus may include: a jig chamber having a door; a first jig device for measuring electrical characteristics, a second jig device for measuring magnetic characteristics, and a third jig device for measuring magnetic characteristics, the three jig devices interchangeably mounted in the jig chamber so that either the first, second, or third jig device may be used to measure a composite material sample.

Abstract: Disclosed is an analysis system and method for visualizing heat conduction of a solid state sample. The analysis system includes a sealed jig chamber, a jig, an air tempering unit, and a thermal image camera. The sealed jig chamber includes a chamber door for opening/closing the jig chamber. The jig is removeably mounted in the jig chamber and comprises a heat source in surface contact with a solid state sample to induce the heat conduction of the solid state sample. The air tempering unit supplies hot air into the jig and supplies cool air into the jig chamber. The thermal image camera photographs the heat conduction of the solid state sample to acquire a thermal image or video.

Abstract: Disclosed is a system for warning a pedestrian of an oncoming vehicle. In particular, a sensor senses the position of a pedestrian in the vicinity of a vehicle. The position information is then sent to a control unit which controls a phase, a frequency, and a volume of a sound signal transmitted to a pair of dipole speakers based on positional information of the pedestrian calculated by the control unit.

Abstract: Disclosed is a radiating apparatus for a battery cell which uses an interface plate which can effectively radiate heat accumulated in the battery. In particular, an aluminum-elastomer structure composite material with excellent thermal conductivity is used as the interface plate. Further, the radiating apparatus includes an outer case having cooling channels, through which cooling air passes to discharge heat generated from a battery cell, and a battery cell and an interface plate which are provided within the outer case and which are alternately stacked to make surface-contact with each other. The interface plate advantageously discharges the heat accumulated in the battery cell using aluminum-elastomer structure composite material.
