The present invention provides a Fresnel lens that can reduce generation of concentric stray light. The Fresnel lens includes a sawtooth corrugated face that is formed by alternately disposing a first face inclined relative to optical axis A and a second face substantially parallel to optical axis A, and a light shielding mask is formed at a position corresponding to the second face.

Provided is a small-sized information display device displaying video image information as a virtual image by use of an eyepiece optical system including a concave mirror having desired reflection characteristics in a specific polarization direction, where a liquid crystal display panel is used as a video image light source. The information display device has a liquid crystal display panel as a flat display forming video image information disposed therein, and includes a virtual image optical system including a member to be projected for displaying virtual images in front of a vehicle by making a video image displayed on the liquid crystal display panel reflect on the member to be projected. The virtual image optical system includes a concave mirror, and a reflective film of the concave mirror has desired reflection characteristics in a specific polarization direction, so that virtual images having uniform brightness and chromaticity can be obtained.

A vehicle is provided that determines a need for communication with a third party vendor, retrieves the user rule from the memory (the user rule defining to which third party vendor the vehicle can send a first communication to address the need and defining a geographic location of the third party vendor relative to a current location of the vehicle, a monetary amount the vehicle can pay to a third party vendor for a product or service to address the need, and a time limit for the third party vendor to provide the product or service to address the need), based on the user rule, selects a third party vendor from among multiple possible third party vendors, and when determined by the user rule, automatically sends the first communication to the selected third party vendor to order the product or service and provides an authorization to the selected third party vendor to complete the order. The vehicle uses different communication protocols to provide the first communication and authorization to the selected third party vendor.

A movable body according to an embodiment of the present disclosure includes a vehicle body and an information display apparatus mounted on the vehicle body. The information display apparatus provided at the movable body includes a light projecting part that projects a luminous flux and a reflector that reflects the luminous flux from the light projecting part. The reflector includes a plurality of unit regions two-dimensionally arranged over a main surface. Each of the unit regions includes a plurality of reflecting surfaces two-dimensionally arranged, and splits a luminous flux entering the plurality of reflecting surfaces to perform reflection in a plurality of directions.

The disclosure includes a method comprising collecting sensor data from an olfactory sensor set of a vehicle, wherein the sensor data describes sensor measurements of an odor of a corresponding vehicle component, wherein the sensor data is received by a server. The method further includes receiving failure data from the server that describe a match between the sensor data and a fingerprint compound that corresponds to a failed vehicle component. The method further includes identifying the corresponding vehicle component that is described by the failure data. The method further includes identifying the corresponding vehicle component that is described by the failure data. The method further includes generating a notification based on the failure data and the corresponding component. The method further includes providing the notification to a driver of the vehicle.

A display device according to one aspect of the present invention includes: a display unit configured to have display information and emits visible light having a continuous spectrum; an infrared cut-off part configured to transmit the visible light from the display unit and to reduce the amount of infrared light striking the display unit; and a reflecting part configured to reflect the visible light having passed through the infrared cut-off part. The infrared cut-off part includes a first polymer film and a second polymer film, the first polymer film includes an infrared cut-off layer configured to reduce infrared light transmission, and the second polymer film includes a high-retardation polyester film and is disposed between the first polymer film and the display unit.

A display device and a mobile object. The display device is installable in a mobile object, and includes a light source, an image former to receive light emitted from the light source and output image light that forms an image, a screen on which the image light forms the image, a housing that houses the light source and the image former, and a holding member to hold the screen. The holding member is attached to the housing with a normal direction of a surface of the screen intersecting with a vertical direction and with a front-and-rear direction of the mobile object. A width of the housing is narrower than a width of the holding member. The mobile object includes the display device, a front windshield to reflect the image light, and an image-forming optical system to project the image light projected from the screen toward the front windshield.

A head-up display device reflects a display light on a projection member to display a virtual image. A light condensing unit causes condensation and collimates an illumination light from a light source unit. A liquid crystal element includes forms an image illuminated with the illumination light. The liquid crystal element emits the display light of the image in a light flux form in an emission direction corresponding to an incident direction of the illumination light. A positive optical element has a positive refractive power. A negative optical element has a negative refractive power. Both of the optical elements are located on the optical path and guide the display light from the liquid crystal element toward the projection member to enlarge a virtual image. The negative optical element on the optical path is located closer to the liquid crystal element than the positive optical element.

A vehicle display control device controls a virtual image display performed by a head-up display which superimposes a display image on outside scenery of the host vehicle. The host vehicle is equipped with an automatic control unit which executes an automatic control to the host vehicle. The vehicle display control device includes: a route information acquisition unit that acquires route information related to a scheduled route of the host vehicle, the automatic control unit setting the scheduled route for the host vehicle; and a route image formation unit that forms a route image indicative of the scheduled route based on the route information acquired by the route information acquisition unit. The head-up display projects the route image as the display image in a virtual image display region that is superimposed on a forward traveling road included in the outside scenery.

The display device includes: a display unit that projects a light beam onto a windshield so that the light beam is reflected from the windshield such that one or more virtual images are displayed in a space further than the windshield in a depth direction through the windshield; and a controller that controls the display unit so that a first vertical image and a second vertical image included in the one or more virtual images and have different distances from the windshield in the depth direction, are displayed in a time-division manner.
