Abstract: A distortion calibration device includes an image acquisition unit which acquires a plurality of test images generated by capturing an image, which is displayed on a display panel, for each channel of the multi-channel lens by a camera and a plurality of reference images generated for each channel with respect to the multi-channel lens and the display panel, and a mapping data generator which acquires an error per channel between the plurality of test images and the plurality of reference images with respect to each channel and generates calibration data for compensating the error per channel to generate calibration mapping data based on reference mapping data and the calibration data.

Abstract: A storage controller and an operating method of the storage controller are provided. The storage controller includes processing circuitry configured to read sub-stripe data from each of a plurality of non-volatile memory devices connected with a RAID (Redundant Array of Inexpensive Disk), check error information of at least one of the sub-stripe data, and perform a RAID recovery operation in response to the at least one of the sub-stripe data having an uncorrectable error, and a RAID memory which stores calculation results of the RAID recovery operation.

Abstract: A display device and a wearable device. The display device may include at least one display panel comprising multiple subsidiary display panels, wherein images output from the subsidiary panels are extended to one another to form a single screen image and at least one multi-channel lens including multiple subsidiary lenses to provide multiple channels for light incident onto the subsidiary lenses, respectively, wherein the subsidiary display panels are associated with the subsidiary lenses, respectively, and the subsidiary display panels are inclined at a first angle from a reference plane so that their front surfaces face the respective subsidiary lenses.

Abstract: The present disclosure relates to a brake pedal displacement sensing apparatus. The brake pedal displacement sensing apparatus includes a magnet assembly including a magnet that moves with the same displacement as that of a pedal rod that is moved by operation of a brake pedal, and a sensing unit including a sensor element, which senses a change in a magnetic field of the magnet and generates an electrical signal corresponding to the displacement of the pedal rod, and a connector, which is electrically connected to an electronic control unit (ECU) circuit board included in a brake control ECU to transmit the electrical signal from the sensor element to the brake control ECU.

Abstract: A display device includes a display portion including a first surface, from which light is emitted in a first direction, and a second surface opposite to the first surface, a first optical portion disposed on the first surface, and a second optical portion disposed on the first surface to be spaced apart from the first optical portion in a second direction crossing the first direction. Each of the first and second optical portions includes a multi-channel lens through which the light from the first surface passes, a first infrared light source, a first camera, and a first lens frame coupled to the multi-channel lens in the first direction to support at least a portion of the multi-channel lens. The first lens frame may include a first recess structure in which the first infrared light source is disposed and a second recess structure in which the first camera is disposed.

Abstract: A mobile terminal including an interface module configured to connect the mobile terminal to a personal computer; a communication unit configured to communicate with the personal computer via a first communication mode, a controller configured to selectively transmit a communication mode change program to the personal computer via the interface module, the communication mode change program instructing the personal computer to communicate with the mobile terminal via a second communication mode that is different than the first communication mode, and a receiving unit configured to receive a mode change instruction from the personal computer instructing the mobile terminal to communicate with the personal computer via the second communication mode.
