    Abstract: A power converter incudes a power factor correction circuit and a controller. The power factor correction circuit is configured to convert an input single-phase electrical power to a first DC electrical power. An active phase of the input single-phase electrical power is received in parallel through two of four conductors. A return phase of the input single-phase electrical power is received in parallel through two others of the four conductors. The power factor correction circuit is also configured to convert an input three-phase electrical power to the first DC electrical power. Three active phases of the input three-phase electrical power are received through three of the four conductors. The return phase is received through a fourth of the four conductors. The controller is configured to control the power factor correction circuit to operate in the single-phase input mode and the three-phase input mode in response to a control signal.

    Abstract: An image enhancement system in a vehicle includes a forward looking light sensor, an ambient light sensor, and an electronic control unit. The forward looking light sensor is configured to sense a forward looking light seen by a driver to generate a forward luminance value. The ambient light sensor is configured to sense an ambient light seen by the driver to generate an ambient luminance value. The electronic control unit is configured to calculate a display luminance control value based on the forward luminance value and the ambient luminance value, analyze a video image in a video input signal to determine multiple shades of gray within the video image, adjust the shades of gray in the video image based on the forward luminance value, the ambient luminance value, and the display luminance control value to generate the enhanced video image, and present the enhanced video image to the display.

    Abstract: An object detection system may include an object detecting device. The object detecting device may generate an object signal based on detecting an object. The object detection system may include a controller for operating a motor. The motor may be connected to a wiper element. The controller may generate a position signal based on a position of the motor. The object detection system may include an object detection module in communication with the object detecting device. The object detection module may receive the object signal and/or the position signal. The object detection system may be configured to selectively control the motor in response to detecting the object.

    Abstract: A high dynamic range display includes a light source, a first display and a second display. The light source is configured to generate a backlight. The first display is aligned with the light source and has multiple first pixels. Each first pixel is configured to selectively pass and block the backlight. The second display is aligned with the first display and has multiple second pixels. A particular pixel is controlled to pass the backlight at a first transmit level. The particular pixel corresponds with an aligned pixel of the first pixels controlled to pass the backlight at a second transmit level and a multiple parallax pixels controlled to pass the backlight. The second transmit level is based on the first transmit level. The second transmit level offsets leakage of the backlight through the second display at the first transmit level to produce a high dynamic range final image.

    Abstract: A power reduced display includes a light source having an available space and configured to generate a backlight, a first display having multiple first pixels, wherein each first pixel is configured to selectively pass and block the backlight, a second display having multiple second pixels. The light source includes a first number of first packages each having a single light-emitting diode. The first number is a largest number of the first packages that fit in the available space of the light source. The first number of the first packages is configured to consume a first power to produce a particular luminance. A second number of second packages each having two light-emitting diodes alternatively fit in the available space and is configured to consume a second power to produce the particular luminance. The first number is greater than the second number. The first power is less than the second power.

    Abstract: A display system includes a backlight configured to project light including a housing and one or more light emitting elements received in the housing and one or more reflective portions disposed on the housing. A first display unit is disposed proximate the backlight includes a liquid crystal layer and at least one reflective polarizer. A second display unit is disposed proximate the first display unit. The second display unit includes a TFT display layer and at least one linear polarizer. At least one microcontroller is in communication with one or more of the backlight, the first display unit and the second display unit. The at least one microcontroller executes instructions to adjust the liquid crystal layer of the first display unit between a first transmissive state and a second transmissive state.

    Abstract: A method for a vehicle includes determining a region of interest based on environment sensor data corresponding an environment of the vehicle and a machine-learned predictor configured to identify, within the environment sensor data, a region as the region of interest that at least statistically coincides with a line of sight of an occupant of the vehicle. The method also includes classifying a detected object within the determined region of interest using an object detection algorithm. The method also includes operating the vehicle in based on at least one of the detected object and the determined region of interest.
