    Abstract: A light apparatus mounted on a vehicle includes a lamp unit having: a first cover, and a light source that emits light through a first cover into a predetermined area including a first direction. The light apparatus also includes: a radar unit provided on a lower side or an upper side of the lamp unit, and a separator provided between the lamp unit and the radar unit. The radar unit includes: a circuit board having a board surface arranged in a substantially horizontal state, and an antenna unit that transmits an electromagnetic wave in a range including a second direction different from the first direction and that receives a reflected wave from an object existing outside the vehicle. The antenna unit is arranged in the board surface.

    Abstract: A multilevel signal transmitting apparatus transmits a multilevel data signal with M voltage levels, and a multilevel clock signal with (M−2) voltage levels, to a multilevel signal receiving apparatus, where M is an even number equal to or more than four. The voltage levels of the multilevel data signal include M/2 first voltage levels larger than a reference voltage level, and M/2 second voltage levels smaller than the reference voltage level. Between each pair of adjacent voltage levels among the first voltage levels, one voltage level of the multilevel clock signal is set. Between each pair of adjacent voltage levels among the second voltage levels, one voltage level of the multilevel clock signal is set. An average of the voltage levels of the multilevel clock signal has a value between a minimum of the first voltage levels, and a maximum of the second voltage levels.

    Abstract: A video data transmitter apparatus generates and transmits a multi-value amplitude modulation signal by performing a multi-value amplitude modulation of a plurality of N bits per one symbol according to video data of a video signal or a color signal constituting the video signal, or a brightness signal and a color-difference signal. A data separator portion separates the video data into first to N-th pixel data, a difference calculator portion calculates (N−1) pieces of predetermined difference information based on the separated first to N-th pixel data, and a multi-value amplitude modulator portion performs a multi-value modulation so that predetermined N-bit data corresponds to a multi-value signal level closest to an intermediate level having an intermediate value between a maximum level and a minimum level of the multi-value signal level of the multi-value amplitude modulation signal.
