A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.

The present invention is to provide a prevention method and a prevention system for preventing dew condensation and light scattering due to the dew condensation. According to one embodiment of the present invention, a fine liquid droplet capable of causing dew condensation is detected by a detection means for detecting a fine liquid droplet, and then the fine liquid droplet is removed on the basis of the detection. The detection means comprises a first thin wire made of a first metal, and a second thin wire made of a second metal or a semiconductor, the second metal is different from the first metal, the first thin wire and the second thin wire are dispose d in juxtaposition with each other on an insulating substrate, and a spacing between the first thin wire and the second thin wire is in a range of 20 nm or more and 10000 nm or less. Further, provided is a prevention system including a detection means for detecting a fine liquid droplet, a removing means for removing the fine liquid droplet, and a control means for controlling the removing means on the basis of information from the detection means.

A vehicle computer includes a memory and a processor programmed to execute instructions stored in the memory. The instructions include comparing a captured image of a predetermined object to a target image of the predetermined object to quantify a first noise characteristic of the captured image, comparing the first noise characteristic to a first predetermined threshold, and detecting debris on an image sensor that outputs the captured image as a result of comparing the first noise characteristic to the first predetermined threshold.

In some embodiments, an electronic device selectively activates and deactivates actuation features in accordance with the context in which an electronic device is operating. In some embodiments, an electronic device controls one or more actuators in accordance with sensor data and/or inputs received using one or more input devices.

A roof module of a motor vehicle, in particular a passenger car, the roof module may have a roof skin, which forms an outer visible surface of the roof module, at least one sensor module having an environment sensor to detect a vehicle environment in an autonomous or semi-autonomous driving mode of the motor vehicle, and a sensor cover forming a see-through area for the environment sensor. The roof module may have a detector for detecting foreign particles on the see-through area of the sensor cover.

A vehicle wiper device includes: a wiper motor; a control unit that drives the wiper motor to be reciprocally rotated and controls a rotation speed of the wiper motor; and a wiper reciprocally rotating to wipe a wiped surface of a vehicle with a blade rubber, in which a tilt direction of a lip part of the blade rubber changes when a rotation direction is reversed. The control unit accelerates a rotation speed of the wiper motor, in a first acceleration section, from 0 to a first speed which is a low speed at a first average acceleration, and to rapidly accelerate the rotation speed of the motor, in a first half of a second acceleration section, to reach a speed which is higher than the first speed and ? times of a second speed at an average acceleration which is twice or more of the first average acceleration.

A lidar sensor may include: a transmitter configured to transmit laser; a receiver configured to receive reflected laser; a mirror rotating unit configured to rotate a mirror in a designated direction, the mirror serving to reflect the transmitted or received laser; a cleaning device driving unit configured to drive a cleaning device to remove foreign matters adhering to the cover of the lidar sensor; a signal processing unit configured to determine when or where the lidar sensor is covered and calculate a distance to an object; and a control unit configured to control the transmitter not to transmit a laser signal or control a rotational velocity or rotation time of the mirror at a point of time that the lidar sensor is covered by the cleaning device, and control detection or utilization of the received signal when the distance to the object is calculated.

An arrangement to reduce refreezing of meltable snow includes a wiper arm configured to wipe the meltable snow from an ambient-facing surface of a window positioned on a vehicle. The arrangement also includes a sensor coupled to the wiper arm that is configured to gather and transmit a parameter on the vehicle and environment. The arrangement also includes a processor that is configured to receiving the parameter, determining refreezability of the meltable snow based on the parameter, and defining an action to be performed by the wiper arm.

A surround view system for a vehicle includes a plurality of brackets adjacent interior surfaces of windows of the vehicle. A plurality of camera assemblies are provided within the brackets. Each camera assembly includes a lens having a field of view extending through one of the windows for capturing images of a vehicle exterior. The images captured by the lenses through the windows are integrated together to form a 360 view of the vehicle exterior.

A product [11] includes a foldable clamshell-type housing [10] folded to a closed position to contain a pre-formed sensor pad [17] that was formed in situ therein when the housing [10] was in an open position, prior to closing. The housing [10] has an enclosed volume [12] bounded by relatively thin and flexible walls [23, 34], and outwardly extending tabs [18] which facilitate opening. This structure enables the user to easily open the housing [10] to remove the sensor pad [17], a cured silicone composition, by pushing inward on an outer surface of the outer wall [34] of a base section [15] of the housing [10]. This product [11] reduces the amount of manipulation needed to place the sensor pad [17] in a desired position, for example, during installation of a rain sensor system for a vehicle windshield.
