An IR illuminator for providing infrared radiation for a digital camera having a camera lens with a camera field of view, including equidistant mounting substrates arranged adjacent to the digital camera, IR LEDs mounted to each of the mounting substrates, and a cover lens positioned to cover the IR LEDs. The shape of the free form cover lens is such that an emission pattern of radiation is emitted without entering into the camera lens and the emission pattern of IR radiation has an asymmetric field of view. Two IR illuminators adjacent to the camera are tilted at an angle from the camera optical direction. The cover lens may be a Fresnel lens, or include a diffractive layer or a collimator to shift radiation emitted from the LED to an asymmetric distribution.

A vehicle theft-prevention apparatus can include a locking mechanism configured to engage to secure the vehicle theft-prevention apparatus into a vehicle and disengage to unsecure the vehicle theft-prevention apparatus from the vehicle. The vehicle theft-prevention apparatus can include a clutch mechanism configured to prevent the locking mechanism from further engaging based on a magnitude of force applied. The clutch mechanism can include a first portion configured to rotate about an axis and comprising at least one aperture, a second portion configured to rotate about the axis and comprising a track, and at least one article configured to pass through the at least one aperture and travel along the track.

A vehicle theft-prevention apparatus can a motor unit configured to rotate based on an electrical signal. A shaft of the motor unit can be coupled to a cam. The cam can move a connection plate between an engaged position and a disengaged position. When the connection plate is in the engaged position, a locking mechanism can move between a locked position and an unlocked position. When the connection plate is in the disengaged position, the locking mechanism can maintain a current position.

A vehicular vision system includes a camera and a plurality of infrared light emitters disposed at a vehicle, and an electronic control unit having an image processor. The camera captures frames of image data at a first rate, and infrared light emitters of the plurality of infrared light emitters are pulsed at a second rate. The plurality of infrared light emitters is operable in (i) a first mode, where infrared light emitters of the plurality of infrared light emitters are operated to emit infrared light to illuminate a region within a field of view of the camera, and (ii) a second mode, where a reduced number of infrared light emitters of the plurality of infrared light emitters are operated to emit infrared light to illuminate the region.

A display system includes: a display that emits light corresponding to image information; a half mirror that receives the light emitted, reflects, as reflected light, a first component of the light received, and transmits a second component different from the first component; and a first reflecting mirror having a concave surface that receives and reflects the reflected light toward the half mirror. The half mirror includes a first retardation film, a first support substrate, and a reflective polarizing film stacked in this order from a side on which the light emitted is received. The first retardation film changes a phase of the light received. The first support substrate is light-transmissive. The reflective polarizing film reflects a first polarized component and transmits a second polarized component different from the first polarized component.

A camera mirror system for a vehicle includes, among other things, a camera that has a field of view, a display in communication with the camera that is configured to depict the field of view, and an infrared light-emitting diode (IR LED) that is configured to illuminate the field of view. The IR LED is configured to operate at a temperature. The system further includes a controller that is configured to provide at least one of a warning or an IR LED shut down command in response to the temperature exceeding a threshold.

A warning system and a method for warning a driver of a vehicle of an object in a proximity of the vehicle. The system includes a device for detecting the object, a device for processing an image of the object based on the detection so that a representation indicative of the object is achieved, and a display for displaying the representation indicative of the object in the vehicle.

A vehicle theft-prevention apparatus can include a body, a computing device, sensors, and a speaker. The body can include a first and second portion and a light emitting portion. The first portion can move relative to the second portion. The second portion can include perforations to facilitate sound transmission from the speaker. The light emitting portion can be positioned between the first portion and the second portion. The light emitting portion can be configured to emit light based on a signal from the computing device. A lens can include a concentric structure protruding from the body. The lens can cover the sensor.

A vehicle theft-prevention apparatus can include a locking mechanism configured to engage to secure the vehicle theft-prevention apparatus into a vehicle and disengage to unsecure the vehicle theft-prevention apparatus from the vehicle. The vehicle theft-prevention apparatus can include a clutch mechanism configured to prevent the locking mechanism from further engaging based on a magnitude of force applied. The clutch mechanism can include a first portion configured to rotate about an axis and comprising at least one aperture, a second portion configured to rotate about the axis and comprising a track, and at least one article configured to pass through the at least one aperture and travel along the track.
