A defogging device includes a heating wire configured to heat a windshield. The heating wire includes a plurality of parallel arrangement portions generally parallel to each other and provided such that respective intermediate parts, in the longitudinal direction, of the parallel arrangement portions are placed inside a field angle region. The parallel arrangement portions include two adjacent parallel arrangement portions provided such that respective first ends, in the longitudinal direction, of the two adjacent parallel arrangement portions are connected to each other via a connecting portion outside the field angle region, and respective second ends of the two adjacent parallel arrangement portions are separated from each other without being connected to each other. The second ends of the two adjacent parallel arrangement portions are connected to heat-amount supplement portions provided outside the field angle region and projecting toward their respective counterparts out of the two adjacent parallel arrangement portions.

A defogging system includes: a vehicle speed sensor configured to detect a vehicle speed; a first heater arranged outside a field of view of an imaging device and configured to heat a window; a second heater arranged inside the field of view of the imaging device, arranged to be in contact with the window, and configured to heat the window; and a controller configured to control the first heater and the second heater. The controller is configured to determine whether the vehicle is stopped based on a detection result of the vehicle speed sensor, activate the first heater and the second heater in a case where a first condition is satisfied, the first condition including a condition that the vehicle is stopped, and activate only the first heater in a case where a second condition is satisfied, the second condition including a condition that the vehicle is traveling.

A system and method to defog and/or defrost a sealed sensor system housing window to improve transmission of an electromagnetic wave through the housing window. The system includes at least a heater provided in a sealed sensor system housing to emit heat into the housing. The heat is then distributed via convection promoted by a moving component of the sensor system, a fan, or a combination of both. Additionally or alternatively, heat may be transferred to the housing window via conduction. A controller can be configured to activate or deactivate the heater based on a determined or predicted state.

To provide a vehicle headlamp that can remove, without using a heater, fogging adhering to an outer lens. A vehicle headlamp includes a housing, an outer lens attached to the housing to form a lamp chamber between the outer lens and the housing, a lighting fixture unit configured to emit visible light that transmits through a visible light transmission region of the outer lens, the lighting fixture unit being disposed in the lamp chamber, an optical probe apparatus configured to emit infrared light that transmits through an infrared light transmission region of the outer lens, the optical probe apparatus being disposed in the lamp chamber, and an infrared light control unit configured to control the infrared light, which is emitted from the optical probe apparatus, such that the infrared light emitted from the optical probe apparatus is radiated to the visible light transmission region of the outer lens.

A windowpane system (101) comprising: a windowpane (102); and at least one primary light source (105); each primary light source (105) being arranged so that light (106) from the primary light source (105) passes into the windowpane (102) through a first surface of the windowpane (102), the light (106) then travelling within the windowpane until it has undergone total internal reflection from one or more second surfaces of the windowpane a plurality of times, wherein at least some of the light from the primary light source is absorbed by the windowpane as the light from the primary light source passes through the windowpane.

An air-blowing device has a wall portion, a duct, and a guide wall. The wall portion is provided with a blowing outlet having an opening periphery extending in one direction. The duct has a first wall and a second wall facing the first wall and therein provides an air passage communicating with the blowing outlet. The guide wall curves from the first wall to be away from the second wall and is connected with an edge providing the opening periphery. The guide wall guides air flowing in the air passage to blow from the blowing outlet in a direction from the second wall toward the first wall. The edge extends to have a shape protruding in a direction from the first wall toward the second wall.

A coating composition for imparting a hydrophobic film on a target surface is provided that, includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.

The wiper-washer control device includes a wiper motor that causes a wiper blade to perform a wiping operation, a washer pump that causes a washer fluid to be sprayed, and a controller that, in cases in which defrosting has been instructed, controls the wiper motor and the washer pump such that a defrosting operation in which the wiping operation and spraying of washer fluid is performed in a predetermined combination.

A condensation inhibiting device includes a condensation inhibiting unit for inhibiting condensation on a first surface, and a thermoelectric generator which powers the condensation inhibiting unit.
