Abstract: A method for operating a multi-transaction memory system, the method includes: storing Logical Block Address (LBA) information changed in response to a request from a host and a transaction identification (ID) of the request into one page of a memory block; and performing a transaction commit in response to a transaction commit request including the transaction ID from the host, wherein the performing of the transaction commit includes: changing a valid block bitmap in a controller of the multi-transaction memory system based on the LBA information.

Abstract: A data storage device includes a storage, and a controller configured to control data exchange with the storage in response to a request of a host device; generate a name space, which is a logical area and includes one or more sub-spaces each serving as a physical area of the storage, in response to the request of the host device; and manage mapping information between the name space and the sub-spaces, wherein each sub-space constituting the name space is selected to have a physically continuous or discontinuous address.

Abstract: A power-supply device and an electronic device including the relate to technology for a data storage device. The electronic device includes a power-supply device and a controller. The power-supply device generates a sudden power loss (SPL) detection signal in a sudden power off (SPO) state by detecting a level of an external power, generates a charging sense signal indicative of a charging capacity of an auxiliary power-supply circuit, divides the charging capacity into a plurality of charging levels, detects a level of the charging capacity, and generates a charging sense signal indicating a charging level of the auxiliary power-supply circuit in response to the detected charging level. The controller stores flushing information in at least one non-volatile memory device when the SPL detection signal is activated, and variably adjust an amount of storage in the non-volatile memory device in response to the charging sense signal.

Abstract: The present disclosure relates to an interference cancellation method and device of an ICS repeater using a leveler, and may effectively cancel only interference signals by using a leveler without using a magnetic correlation cancellation device or digital filter in order to cancel unnecessary noise signals generated by narrow-band signals and enable an ICS repeater design for an LTE wireless network that needs a short system time delay.

Abstract: A method for displaying three-dimensional integral images using a mask and a time division multiplexing which is configured in such a way that a three-dimensional image is displaced in a space as an element image obtained from a three-dimensional object is passed through a lenslet and a mask, the mask consisting of a blocking region through which an element image does not pass and a transmission region through which an element image passes, for thereby displaying three-dimensional images. The present invention is advantageous to play back a three-dimensional image the resolutions of which are enhanced in a depth-based integral imaging method using a time division display of an element image and a masked image.

Abstract: A three-dimensional image display method is disclosed. The three-dimensional image display method in accordance with an embodiment of the present invention includes: displaying an object image; displaying a background image by using a three-dimensional image display method; and disposing the object image at a close distance and the background image at a far distance such that the object image and the background image overlap inside a same viewing angle. By using images having a different sense of depth, a high-resolution image can be displayed while providing a sense of reality.

Abstract: A two dimensional to three dimensional (2D-3D) convertible display device is disclosed. In one embodiment, the display device includes i) a first display unit configured to selectively output one of a composite image and backlight, wherein the composite image comprises a background image and a mask image, for an object, wherein the background image comprises element images for a background excluding the object and wherein the mask image is a white image which has the same shape as that of the object, ii) a lens unit configured to convert the composite image into a stereoscopic image or pass through the backlight and iii) a second display unit configured to output i) a two-dimensional (2D) image of the object by the use of the backlight at a 2D mode and ii) the combination of the 2D image and the composite image at a three dimensional (3D) mode.
