A control unit, in a disclosed embodiment, includes a transceiver, memory, and a processor. The processor is coupled to the transceiver and memory and executes instructions from the memory to cause the control unit to receive a first transmission containing a certificate, verify the authenticity of the certificate, and, after verifying authenticity of the certificate, execute a public key agreement protocol to generate a first common secret encryption key, receive a second transmission containing an encrypted first public key that is encrypted by the first common secret encryption key, decrypt the encrypted first public key using the first common secret encryption key to determine the first public key, execute a public key agreement protocol to generate a second common secret encryption key, generate an operational key, encrypt the operational key using the second common secret encryption key, and transmit the encrypted operational key.

A vehicle seat with touch control function includes a seat armrest, the seat armrest includes an armrest frame, a flexible pad, a flexible touch panel, and a protective cover. The flexible touch panel is elastic, and the flexible touch panel includes a flexible substrate and a carbon nanotube touch function layer to collect touch input from a user. Such flexible touch panel may be installed on or in armrest of any seat in vehicle, enabling control of a display while comfortably seated, having to lean forward is avoided. A vehicle-mounted entertainment system incorporating such touch control system is also provided.

Provided is an electronic device whose display quality is independent of environment light. The electronic device is provided with an optical sensor, an acceleration sensor, and the like so that information including the brightness of external light, the angle of external light incident on the electronic device, and the orientation of the display portion in the electronic device is obtained, and the luminance and color tone of the display portion in the electronic device are corrected on the basis of the information. As the correcting method, calculation using a neural network is performed using the luminance and color tone meeting the preference of the user as teacher data and the obtained information as input data. The calculation result is reflected on the luminance and color tone of the display portion in the electronic device, whereby an image with display quality that suits the user's preference can be displayed.

A laminated glass includes a first glass plate; a second glass plate with a plate thickness which is less than a plate thickness of the first glass plate; and an intermediate film. The first glass plate and the second glass plate are laminated via the intermediate film. An external dimension of the second glass plate is less than an external dimension of the first glass plate. At least a part of an outer peripheral edge of the second glass plate is located on an inner periphery side with respect to an outer peripheral edge of the first glass plate.

A motor vehicle having a rear view device with no wing mirrors is disclosed. The rear view device includes at least one camera, by which at least one part of a rear space/traffic situation can be recorded, and at least one screen, on which the image section recorded by the at least one camera can be displayed. The at least one screen is arranged on a console of a side door protruding towards the vehicle interior, where this console engages at least partially with a recess of the dashboard when the side door is closed.

A display device is provided. The display device includes a plurality of diffractive optical elements each configured to emit light guided in a light guide plate to a user. Virtual images by the light are observed by the user at two or more different depths according to the plurality diffractive elements.

A light controlling film comprises a light reflecting film and a light controlling layer that are laminated. The light reflecting film comprises at least two laminated light reflecting layers including at least one of light reflecting layers PRL-1 to PRL-3 that a central reflection wavelength of 400 nm-500 nm, 500 nm-600 nm, and 600 nm-700 nm, respectively, and a reflectance to ordinary light at the central reflection wavelength of 5%-25%. The at least two light reflecting layers have central reflection wavelengths that are different from each other. All of the at least two laminated light reflecting layers have a property of reflecting polarized light having the same orientation. The light controlling layer comprises two quarter wave plates, and the light reflecting film is laminated so as to be interposed between the two quarter wave plates.

A display device includes a beam generator and a holographic optical waveguide. The beam generator includes a display and is configured to generate beams having image information displayed on the display. The holographic optical waveguide is configured to display an image of a second size at a position at a first distance behind the display device based on the beams having the image information, the second size is a multiple of the first size of the display, and the multiple is greater than 1.

The present disclosure relates to a vibration generation device, a display apparatus including the vibration generation device, and a vehicle including the vibration generation device. A vibration generation device includes a piezoelectric ceramic part having a certain interval, a piezoelectric material layer between the piezoelectric ceramic parts, and an electrode part configured to provide electric field to one or more of the piezoelectric ceramic part and the piezoelectric material layer.

A vehicle including a plurality of displays disposed at different positions inside the vehicle, each display including a touch screen and a cover layer on a top surface of the touch screen, the cover layer of a corresponding display having a color characteristic based on an interior part of the vehicle having the display such that when the corresponding display is off, the corresponding display appears hidden; a sensor configured to detect a seat location of a person seated in the vehicle; and a controller configured to selectively control the plurality of the displays based on the detect seat location of the person seated in the vehicle.
