  • Fish eye camera having a bracket which elastically supports plurality of light emitting diode (LED) substrates
    Patent number: 10728431
    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.

  • Apparatus for braking counter shaft of transmission
    Patent number: 7611003
    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.
