Provided is a vehicle including one or more of an IR emitter, ring lens, ring wedge, or any combinations thereof. In an embodiment, an infrared emitter configured to output energy. A ring lens receive the energy output by the infrared emitter and converges the energy to a predetermined field coverage. The predetermined field coverage is determined based on, at least in part, the surface to be heated. The surface to be heated receives the converged energy and is heated.

The various implementations described herein include a camera device that includes: (1) a housing; (2) an image sensor positioned within the housing and having a field of view corresponding to a scene in the smart home environment; (3) at least one infrared (IR) illuminator positioned with the housing, the IR illuminator configured to selectively illuminate the scene; and (4) a front face that is at least partially concave-shaped and coupled to the housing, the front face positioned in front of the image sensor such that light from the scene passes through the front face prior to entering the image sensor, and the front face positioned in front of the IR illuminator such that IR light from the IR illuminator is directed through the front face.

A microscope objective for imaging a specimen using a microscope, the microscope objective having a front lens enclosed by a surround and being designed for microscopy with an immersion liquid. In the microscope objective, the front lens and/or the surround thereof is provided with a coating which can be switched between a state which repels the immersion liquid and a state which does not repel the immersion liquid.

At a camera device for a vehicle, a camera images an obverse side of a glass cover via the glass cover. A water repelling film is formed on an obverse side surface of the glass cover. A transparent conductive film of the glass cover generates heat, and the glass cover is heated. Because the transparent conductive film is electrically conductive, electrical resistance of an obverse side surface of the water repelling film can be lowered by the transparent conductive film, and charging of the obverse side surface of the water repelling film can be suppressed.

The technology relates to a system for clearing a sensor cover. The system may comprise a wiper comprising a wiper support, a wiper blade, and a sensor cover. The wiper blade may be configured to clear the sensor cover of debris, and the sensor cover may be configured to house one or more sensors. A wiper motor may rotate the wiper and a sensor motor may rotate the sensor cover. The system wiper blade may comprise a first edge attached to the wiper support and a second edge which may be configured to be in contact with the sensor cover. The wiper blade may extend in a corkscrew shape around the wiper support. The wiper motor may be configured to rotate the wiper in a first direction and the sensor motor may be configured to rotate the sensor cover in a second direction opposite the first direction.

The invention relates to a system for cleaning the front pane of a camera housing of at least one multi-sensor camera unit. The system includes at least one multi-sensor camera unit with a camera housing having a front pane. At least one supply unit for the provision of a gaseous cleaning medium is provided, the supply unit being connected to at least one nozzle unit allocated to the front pane of the camera housing via at least one supply line, and wherein the at least one nozzle unit supplies the external surface of the front pane with the gaseous cleaning medium provided by the supply unit via the supply line.

An imaging system configured for automatic application and/or removal of immersion media can include (i) a sample stage, (ii) an imaging assembly disposed on a first side of the sample stage and having an immersion objective configured to selectively align with an optical axis of the imaging system, and (iii) an applicator positioned to selectively interact with a lens surface of the immersion objective to deposit or remove immersion media.

The disclosure relates to a method for operating a cleaning system for cleaning a sensor surface of a sensor of a vehicle, in particular an optical sensor, having the step: applying an amount of compressed air to the sensor surface in an air cleaning step characterized by: checking an air cleaning result in a checking step; in the event of a negative air cleaning result, performing a hybrid cleaning step including: applying an amount of cleaning fluid to the sensor surface in a fluid, in particular liquid, cleaning step; and/or, applying an amount of compressed air to the sensor surface in a further air cleaning step.

A mirror unit includes a mirror device includes a support portion and a movable mirror portion configured to be movable with respect to the support portion, and a package including a light incident opening and accommodating and holding the mirror device such that light incident from the light incident opening is able to be incident on the movable mirror portion. The package is provided with a ventilation port communicating an inside and an outside of the package.

A contamination sensor for an optical sensor observation window includes a source, two prisms, a detector, and a controller. The source can emit a collimated light beam at an incident angle that is greater than a critical angle of an interface between a fluid and the window. The window has a refractive index greater than the refractive index of the fluid. The prisms can direct the collimated light beam within the window such that the collimated light beam reflects within a contamination detection zone of the window. The detector can receive the collimated light beam. The controller can communicate with the source and detector. The controller can calculate an emission/detection ratio defined by a difference between an amount of light emitted by the source and an amount of light that passes from the source to the detector by a total internal reflectance of the window.
