A device for indicating lock status of a motor vehicle door includes a door lock status indicator carried on a window of the motor vehicle door. A window for a motor vehicle includes a luminescent door lock status indicator, a luminescent turn signal indicator and a luminescent blind spot indicator.

A system and method are provided and include a light source projector with a positional actuator mounted on a subject vehicle that projects a laser line on a roadway upon which the subject vehicle is traveling. A controller is in communication with a platoon vehicle traveling in front of or behind the subject vehicle in a platoon and controls the positional actuator to project the laser line on the roadway between the subject vehicle and the at least one platoon vehicle.

A car door opening pre-detection system for a car includes a first detecting module, a second detecting module and a control module. The first detecting module is installed within the car. The first detecting module issues a motion detecting signal according to a result of detecting a motion of a palm. The second detecting module is installed outside the car. When the car is stopped, the second detecting module is enabled to selectively provide a first detection range or a second detection range. The control unit judges whether a car door of the car is about to be opened according to the motion detecting signal. When the car is stopped and the control module judges that the car door is about to be opened, the second detecting module provides the second detection range to detect whether there is a moving object behind the car.

A system and method are provided and include a light source projector with a positional actuator mounted on a subject vehicle that projects laser lines on a roadway upon which the subject vehicle is traveling. A controller receives steering angle data from a steering system of the subject vehicle, the steering angle data corresponding to a steering angle of the subject vehicle. The controller determines a turning path of the subject vehicle based on the steering angle data and controls the positional actuator to project the laser lines on the roadway to correspond to the determined turning path of the subject vehicle.

A system and method are provided and include light source projectors with positional actuators mounted on a subject vehicle. A controller controls the light source projectors and the positional actuators to project at least one laser line on a roadway upon which the subject vehicle is traveling. A location of the at least one laser line corresponds to at least one blind spot alert area of the subject vehicle.

A system effective to communicate a message between two devices. A first device may include a plaintext to monoid element module effective to receive a plaintext message and apply a first function to the plaintext message to produce a first monoid element. A monoid element evaluator module may be effective to receive and insert submonoid generators into a monoid expression to produce a second monoid element in response. An encryption device module may be effective to apply a second function to the first monoid element, the second monoid element, the monoid expression, and a third monoid element to produce an encrypted plaintext message. Decryption may be performed on the encrypted plaintext message knowing the private key which includes the first function, the second function, the third monoid element and the submonoid generators list.

A vehicle lamp for emitting light at various locations adjacent to a vehicle while having a simplified configuration is provided. A vehicle lamp includes a light-emitting unit that emits light to form a road surface pattern, and a movable unit on which the light-emitting unit is mounted. The light generated by the light-emitting unit enables the road surface pattern to be formed on different locations of a road surface adjacent to the vehicle as the movable unit rotates.

A vehicle part including a light source capable of emitting a light image, a micro-mirror plate capable of projecting the light image outside the vehicle part in the form of a hologram, a privacy filter located between the light source and the hologram, and a sensor capable of detecting the presence of any object in a projection plane coinciding at least partially with the hologram.

A cross-traffic warning system for a motor vehicle includes first and second input devices transmitting associated first and second input signals for first and second detected objects positioned on the roadway. The system further includes a computer having one or more processors and a computer readable medium storing instructions. The processor is programmed to determine that the first object is a Vulnerable Road User (“VRU”) travelling on a first path based on the first input signal. The processor is further programmed to determine that the second object is a third party vehicle and further that the VRU and the third party vehicle are travelling on an associated one of first and second paths to imminently collide with one another based on the first and second input signals. The processor is further programmed to generate an actuation signal in response to the processor determining the imminent collision.

A beacon provides an image projected onto a roadway at a distance from the vehicle to alert other vehicles as to the presence and speed and/or the deceleration (braking) of the vehicle. The beacon can include a laser that projects an image onto the roadway at a distance behind the vehicle. The laser is able to project this image through fog or other low visibility conditions. The image projected onto the roadway can be a recognizable image such as a universally recognized warning symbol. Alternatively, or additionally, a beacon can be mounted to a front of a vehicle which can alert a moving leading vehicle as to the presence of a moving trailing vehicle in low visibility conditions. The beacon can also be used to alert the driver of inadvertent crossing the roadway lane divider markings either visibly or electronically, in low visibility conditions.
