Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: Provided is a method of compressing an occupancy map of a three-dimensional (3D) point cloud, and more specifically, a method of compressing an occupancy map of a point cloud in which an occupancy map image of a point cloud existing in a 3D space is compressed based on a compression quality or a patch-by-patch inspection method of the occupancy map image so that compression distortion is minimized when reconstructing the compressed occupancy map image so as to remarkably improve the quality of a reconstructed occupancy map image.

Abstract: Disclosed is a method of preparing sodium-catalyzed iron-aluminum inorganic catalyst for catalyzing a hydrogenation reaction of carbon dioxide. The method of preparing sodium-catalyzed iron-aluminum inorganic catalyst includes: a first step of mixing a precipitant solution formed by dissolving a basic precipitant with a reaction solution formed by dissolving an iron (Fe) precursor material and an aluminum (Al) precursor material, thereby forming a suspension solution; a second step of aging the suspension solution; a third step of separating powder from the aged suspension solution; a fourth step of drying the separated powder and then performing a first heat treatment, thereby forming first catalyst powder; and a fifth step of adding and stirring the first catalyst powder and a sodium precursor material to water and evaporating the water and then performing a second heat treatment, thereby preparing a sodium-introduced iron-aluminum inorganic catalyst.

Abstract: A display device includes: a display panel including a display area including pixels and a non-display area including a dummy pixel; a scan driver which supplies a scan signal to the display panel; a data driver which supplies a data signal to the display panel; and a timing controller which supplies a first control signal for controlling the scan driver and a second control signal for controlling the data driver. The dummy pixel is connected to a bad pixel among the pixels in the display area through a repair line, and a connection of the dummy pixel to the repair line is cut off in an initialization phase in which a voltage of an initialization power source is supplied.

Abstract: Disclosed are an apparatus and a method for Internet of Things (IoT) device security. The method includes unifying a port in a first IoT device for communication, receiving, by the first IoT device, a packet from a second IoT device through the port, identifying whether the packet in the first IoT device is in a preset packet form, verifying content of the packet in the first IoT device when the packet is in the preset packet form, and opening the port for providing a service in the first IoT device when the verifying of the packet content is successful.

Abstract: Provided is a method of automatically combining a farm vehicle with a work machine including confirming a current position of the work machine, moving a farm vehicle into a range having a predetermined radius around the current position, and controlling the farm vehicle, on the basis of a current position and direction of a first coupling unit included in the work machine, so that the first coupling unit and a second coupling unit included in the farm vehicle are coupled to each other.

Abstract: A security device includes a case for retaining an information storage device in the space between a front case and a rear case, plurality of locking sleeves protruding from the front case and the rear case, the locking sleeves is formed to engage each other in the manner that the holes of the locking sleeves are aligned in a closed position of the case, and a locking mechanism for latching the case, the locking mechanism inserted into the aligned holes of said locking sleeves in closed position of the case. The locking mechanism includes a housing, a hook which is selectively locked to the protrusion formed on the locking sleeve and released from it by extruding from the case and pulling back into the case, a moving member which is mounted on the slope and moves up and down the slope by magnetic force, while contacting with the side surface of the hook. The hook moves to the locking position or releasing position as the moving member goes up and down the slope.
