A device for detecting a vehicle comprises an image capturing an image of a view in front of the own vehicle. The apparatus comprises first and second determining means, distance detecting means, and storing means. Of these, in the storing means, a relationship between distances to light sources of vehicles and a range of levels of a signal to be imaged at light sources is previously stored. The first determining means determines a particular area in data of the captured image, the particular area being defined by pixels having signal levels higher than a predetermined level. The distance detecting means detects a distance from the image sensor to a position at which the particular area is imaged. The second determining means determines whether or not the particular area is the light source, by referring the detected distance and a signal intensity of the determined particular area to the relationship.

In ventilating a roof, an eave vent and a ridge vent are provided. The eave vent and ridge vent each is equipped with a fabric filter. The fabric filter is not waterproof and is wettable and hence self-cleaning. The permeability to air of the eave vent fabric filter is less than that of the ridge vent fabric filter and the resistance to air flow of the eave vent is greater than that of the ridge vent. The attic space under the roof acts as a manifold, distributing low pressure throughout the attic space.

A method for controlling a light emission from at least one headlight of a vehicle combines lane information with respect to a course of a road and position information with regard to at least one other vehicle located in the course of the road, in order to ascertain an envelope area not to be illuminated around the at least one other vehicle. The method also includes setting, based on the envelope area, a safety distance between (i) light able to be emitted by the at least one headlight of the vehicle, and (ii) the at least one other vehicle, in order to control the light emission.

The invention relates to a light emitter adapted for emitting light with a predefined angular color point distribution, to a method of use for a light emitter in video flash applications, in automotive headlight applications and/or in automotive lamp applications, and to a method, adapted for generating light with a predefined angular color point distribution. The light emitter is adapted for emitting light with a predefined angular color point distribution through an output and comprises a phosphor (2) and a pump source (1), wherein the pump source (1) is adapted for emitting pump light to at least part of the phosphor (2), and the phosphor (2) is adapted for emitting phosphor light by light conversion of absorbed pump light, and wherein a matching element (4) is provided which is arranged at least partly between the phosphor (2) and the output of the light emitter, and which is adapted for adjusting the ratio of the light intensity of the emitted phosphor light emitted by the phosphor (2) towards the output of the light emitter to the light intensity of the transmitted pump light going through the phosphor (2) towards the output of the light emitter. In this way, a versatile light emitter with a predefined angular color point distribution in conjunction with any desired angular light intensity distribution is provided at low costs.

A method for recognizing an intensity of an aerosol in a field of view of a camera of a vehicle includes: reading in image information of an image of the camera, providing a color indicator value for at least one subsection of the image, the color indicator value representing a relation between (i) a first parameter representing a value obtained with application of a first color filter to the image information in the subsection, and (ii) a second parameter representing a value obtained without application of a color filter, or with application of a second color filter differing from the first color filter, and providing a gradient indicator value representing a brightness difference of a different image region of the image, an aerosol intensity value being determined using the color indicator and the gradient indicator values.

A vehicle emergency light beam system for the purpose of coupling to a disabled vehicle in order to warn oncoming motorists with indirect lighting. The rear facing light utilizes a programmable plurality of light fixtures each of which is directed using a light visor extension in a manner that avoids blinding an approaching driver. The device can emit various light colors and modes such as strobe, flashing, or constant light making it versatile in the event of a breakdown no matter what time of day it is. The device may be removably coupleable to a vehicle or alternately integrated into a vehicle's body.

Objectives: To improve the cutting sharpness and life while the manufacturing cost is being lowered. Solution mechanism: The whetstone particle layer (13), which consists of multiple whetstone particle layer units (12), . . . , is configured on the surface (11a) of the whetstone substrate (11) while the respective whetstone particle layer units (12) are being mutually linked via the bridge unit (9). The non-whetstone particle unit (22) is configured between [adjacent] whetstone particle layer units (12) and (12). [Each] whetstone particle layer unit (12) is obtained by configuring the superwhetstone particles (14) densely in the central unit (12a) and by configuring them sparsely in the peripheral unit (12b). The metal coupling phase (17), to which the superwhetstone particles (14) are fixed, is formed by the first and second metal plate phases (15) and (16), respectively. The thickness of the first metal plate phase (15) decreases from the central unit (12a) toward the peripheral unit (12b) in the shape of a mountain.

At least one retaining member is operably associated with the plurality of warp elements to form an integral screen segment having a plurality of openings. The first warp element has at least one characteristic different from the second warp element to prevent blinding of the screen segment. The at least one characteristic affecting movement of the first warp element and the second warp element when the screen segment is used to classify material such that at least one of amplitude and frequency of movement of the first warp element is different from that of the second warp element when subjected to the same operating condition.

A system, method, and console for interactive gaming including an anti-blinding target game is disclosed. The system includes a console, a LIDAR system, and a server all of which are communicatively coupled via a network. The console is configured to project gameplay visuals while continuously using the LIDAR system to monitor the gameplay environment. Upon the LIDAR system detecting a significant modification to the gameplay environment, the console initiates an anti-blinding mode resulting in black light being emitted from the console in order to prevent impacting the eye health of users.
