A device cover including an upper portion, a lower portion, and a fastener is disclosed. The upper portion includes a top surface, upper sidewalls extending downwardly from a perimeter of the top surface, and a transparent section carried by the top surface. The lower portion includes a lower surface and lower sidewalls extending upwardly from a perimeter of the lower surface. The fastener has a first side connected to the upper portion and a second side connected to the lower portion. An attachment portion is positioned on an end portion of the fastener and connected to a portion of each the upper portion and the lower portion. The first and second sides of the fastener are cooperatively configured to secure to one another. The upper and lower portions are cooperatively adapted to form a void and to operably carry a device within the void.

Embodiments of the present disclosure are directed to field device housing assemblies and field devices that include the housing assemblies. One embodiment of the field device housing assembly includes a main housing, a cover having a proximal end connected to the main housing, a transparent panel and a retainer ring. An interior wall of the cover includes a threaded section that is concentric to a central axis, and a flange extending radially inward from the interior wall toward the central axis. The transparent panel is received within a socket defined by the interior wall and the flange. The retainer ring is secured to the threaded section of the interior wall. The transparent panel is clamped between the retainer ring and the flange.

A cover panel, for at least partially transparently covering at least one display instrument in a vehicle, has a microstructure applied on at least one surface. The microstructure is suitable for scattering visible light which is incident on the cover panel. The at least one window region of the cover panel is cutout from the microstructure. A method for manufacturing such a cover panel uses a molding tool with an applied microstructure matrix for forming a microstructure on a part of the molding tool which is assigned to a surface of a molded cover panel. The parts of the molding tool which are assigned to window regions are cut out from the microstructure matrix.

Described herein are apparatuses and methods for selectively controlling the application of a fluid to a sensor enclosure such as a camera housing to protect the housing from overheating. An apparatus that includes a protective shield and a conduit such as tubing for supplying a fluid is described. The protective shield is provided so as to protect an exterior surface of the camera housing from heat caused by sun exposure. The tubing includes an inlet for supplying a fluid such as water or air, can extend through or around an exterior of the camera housing, and includes an outlet with one or more nozzles for ejecting the fluid into a space between the protective shield and the camera housing. Sensor data is received from various vehicle sensors to assess the temperature of the housing, the velocity of the vehicle, and so forth to determine when the fluid should be supplied.

Provided is a vehicle display device which exhibits high visibility, and which has an attractive external appearance. A vehicle display device according to the present invention is provided with: pointer-type instruments (a speedometer and an engine tachometer; a display disposed next to the pointer-type instruments; and a planar protective plate which has, formed on the front surface thereof, a first reflected-light suppression layer. The protective plate is disposed so as to cover the front surfaces of the display and the pointer-type instruments. Furthermore, in the protective plate, light-blocking layers for concealing spaces between the display and the pointer-type instruments are formed. Moreover, a light-transmitting bonding layer, which covers and bonds a display surface of the display, and second reflected-light suppression layers, which cover the front surfaces of the pointer-type instruments, are formed on the rear surface of the protective plate so as to not overlie each other.
