Abstract: A sensor apparatus includes a housing, a LIDAR sensor attached to the housing, a window attached to the housing, and a film covering the window and removable from the window. The window may be cylindrical. The film may be a first film, and the sensor apparatus may include a second film covering the first film and removable from the first film.

Abstract: According to an embodiment, a method of bonding an injection molded plastic to a glass substrate is disclosed. The method includes applying a silica coating to a surface of the glass substrate; injection-molding a plastic substrate, modified with a silane coupling agent, on to the glass substrate to adhere the plastic substrate to the surface; and curing the plastic substrate to covalently bond the silane coupling agent to the silica coating.

Abstract: A sensor apparatus includes a housing, a LIDAR sensor attached to the housing, and a window releasably coupled to the housing. The window may be cylindrical. The housing may be a first housing, and the sensor apparatus may include a second housing. The window may be releasably coupled to the second housing.

Abstract: A vehicle system includes a processor programmed to receive sensor signals from a LIDAR sensor. The processor estimates frost accumulation on the LIDAR sensor from the sensor signals and compares the estimated frost accumulation to a predetermined threshold. The processor further prevents a host vehicle from operating in an autonomous mode if the estimated frost accumulation exceeds the predetermined threshold.

Abstract: Methods and systems are disclosed for analyzing the adhesiveness of enamel frits using topography. One method includes analyzing a topography of a defined area of an enamel frit surface having a plurality of peaks and determining a topographical parameter of the defined area based on peak shape and/or density. The determined topographical parameter may be compared to a threshold value. The method may then include applying an adhesive to the enamel frit and bonding the enamel frit to a substrate if the determined topographical parameter is below the threshold value. The analysis of the topography may be performed using a non-contact profilometer, such as an optical profilometer. In one embodiment, the topographical parameter may be developed interfacial roughness (Sdr). The method may be integrated into a manufacturing/assembly line for vehicle glass components, such as windshields or side windows.
