An example warning device can include: a plurality of light sources forming an array; a plurality of reflectors, with at least one reflector being associated with each of the plurality of lights; at least one lens for each of the plurality of lights; and an optical prism plate that directs light from one or more of the plurality of lights to one of a plurality of far field light spots.

A U-turn signal system; the U-turn signal system includes an exterior-vehicle illuminating U-Turn signal assembly, an interior-vehicle illuminating U-Turn signal assembly, and an activation device having a radio frequency transmitter in wireless communication with the exterior-vehicle illuminating U-Turn signal assembly and the interior-vehicle illuminating U-Turn signal assembly each having radio frequency receivers. The U-turn signal system may be installed on a host-vehicle and provides means for indicating an intent to make a U-turn.

Disclosed are a situation notification apparatus and a transportation means comprising same, wherein the situation notification apparatus, which is mounted in a transportation means and emits light such that the presence of the transportation means is notified to the periphery thereof, comprises: an image projection means configured to project an image onto the ground on the periphery of the transportation means; a memory unit in which a plurality of images are stored; and a microcomputer for controlling the image projection means and the memory unit such that at least one image among the plurality of images is projected onto the ground on the periphery of the transportation means.

A visual deceleration indicator signals to pedestrians and other vehicles that a vehicle is slowing down or coming to a stop. Illuminating devices, such as LEDs, contained in a license plate frame located in the front of the car or otherwise, are activated when the vehicle decelerates. An accelerometer or other sensory device detects deceleration and sends a signal to illuminate the LEDs, thereby letting others know the vehicle is slowing down. The license plate frame may be connected directly to a rear brake light component without the use of accelerometers or other sensors. When the brake is applied, the LEDs in the license plate frame are illuminated. The LEDs may be contained in other forms and located in different positions on the front or side of the car. The indicator might be one color to indicate braking and another color to indicate it is on, but not braking.

The invention relates to a signalling device (1) designed to be removably placed on the back of a user of a locomotive engine, the device (1) including electronic means for signal processing and for controlling the switching-on and/or switching-off of the at least one secondary signal light (3d, 3g) synchronously with the switching-on and/or switching-off of a primary signal light present in the machine. Electronic means are built into an accelerometer and means for interpreting measurements of the accelerometer allow the detection of a lateral variation, to the right or left, of the direction of movement, the means for controlling the at least one secondary signal light (3d, 3g) comprising means for verifying that the at least one secondary signal light (3d, 3g) indicates the lateral right or left direction followed by the user and the machine.

A method for controlling and switching operational modes of an additional lamp for a vehicle includes confirming a pre-set operating mode of the additional lamp. The additional lamp is switched from the pre-set operating mode to another operating mode only when a continuous first signal and intermittent plural second signals come from the vehicle. When the brake is operating and the additional lamp is in a non-flickering mode, the additional lamp generates non-flickering light. When the brake is operating and the additional lamp is in the flickering mode, the additional lamp generates flickering light. The additional lamp is turned off when the braking operation stops. When the braking operation continues and the additional lamp is in the flickering mode, the additional lamp keeps outputting flickering light. When the braking operation continues and the additional lamp is in the non-flickering mode, the additional lamp keeps outputting non-flickering light.

A display device for a movable object includes: a display unit provided such that it is visible from outside a movable object; and a controller that causes the display unit to display information indicating a status of the movable object. The controller changes a display mode of the information displayed on the display unit in accordance with variation in the status of the movable object.

A vehicle and a method of controlling the vehicle are capable of outputting a sound similar to an original sound by modulating a sound signal obtained using a plurality of microphones of an external terminal device considering the physical characteristics of a user and the sound reproduction space. The vehicle includes: a speaker; a sensor module configured to detect a state of the vehicle; a communicator including a plurality of microphones and configured to receive a sound signal having two channels, information about sensitivity of each microphone of the plurality of microphones, and information about a relative position between the plurality of microphones; and a controller configured to: modulate the sound signal on at least one of the sensitivity of the plurality of microphones, the relative position between the plurality of microphones, and a Head-Related Transfer Function (HRTF); remove the reverberation from the modulated sound signal; and control the speaker.

A U-turn signal system; the U-turn signal system includes an exterior-vehicle illuminating U-Turn signal assembly, an interior-vehicle illuminating U-Turn signal assembly, and an activation device having a radio frequency transmitter in wireless communication with the exterior-vehicle illuminating U-Turn signal assembly and the interior-vehicle illuminating U-Turn signal assembly each having radio frequency receivers.
