Abstract: The present disclosure relates to an antenna RF module, an RF module assembly including the antenna RF modules, and an antenna apparatus including the RF module assembly. Particularly, the antenna RF module includes an RF module, a radiation element module arranged on a first side of the RF filter, and an amplification unit board arranged on a second side of the RF filter, an analog amplification element being mounted on the amplification unit board. A plurality of antenna RF modules constitute the RF module assembly, and the RF module assembly and an antenna housing constitute the antenna apparatus. Accordingly, a radome that interrupts dissipation of heat to in front of an antenna is unnecessary, and heat generated from heat generating elements of the antenna apparatus is spatially separated. Thus, it is possible that the heat is dissipated in a distributed manner toward the front and rear directions of the antenna apparatus. The effect of greatly improving performance in heat dissipation can be achieved.

Abstract: Disclosed are a self-generating pressure-sensitive light-emitting device and a method of manufacturing the same. The self-generating pressure-sensitive light-emitting device includes an electrochemical light-emitting device in which a first electrode, a light-emitting layer and a second electrode are sequentially formed; and a triboelectric self-generating device formed on the second electrode and configured to share the second electrode of the electrochemical light-emitting device, wherein the electrochemical light-emitting device and the triboelectric self-generating device share the second electrode and thus the electrochemical light-emitting device is driven due to a potential difference generated from the triboelectric self-generating device.

Abstract: A fish eye camera is provided. A main circuit board is fixed to an inside of a base housing. A middle housing is formed to cover both of the main circuit board and a camera module and fixed to the base housing in a state in which a fish eye lens of the camera module is drawn from the middle housing. A bracket includes a bracket body, which is insertion-coupled to a plurality of light emitting diode (LED) substrates and elastically supports the plurality of LED substrates in a state in which the plurality of LED substrates are arranged around an outer side of the middle housing, and metal bodies which are inserted into the bracket body to be in contact with the LED substrates. A cover housing is formed to cover both of the bracket and the middle housing and fixed to the base housing.

Abstract: An apparatus for braking a counter shaft of a transmission, where the apparatus can cut off power delivery to the transmission and simultaneously reduce a rotation speed of the counter shaft for an easier gear shift. The apparatus includes: a transmission case; a counter shaft in the transmission case; a counter shaft brake that is engaged with the counter shaft and variably stops the counter shaft; and a counter shaft brake operating fork for operating the counter shaft brake.
