Abstract:
An apparatus includes an operational amplifier circuit comprising at least one operational amplifier and a feedback circuit coupled between the output terminal and input terminal of the operational amplifier circuit and configured to apply a feedback gain to an output signal at the output of the first operational amplifier. The apparatus further includes a variable compensation capacitor coupled to the output terminal of the operational amplifier circuit and configured to vary a capacitance thereof responsive to the feedback gain.
Abstract:
A decoder includes multiple decoder stages and a controller. The decoder stages perform decoding operations with respect to a received signal using corresponding different decoding algorithms. The controller determines whether the decoding operation performed by one of the decoder stages with respect to the received signal is successful, and controls the decoding operation of each of the other decoder stages in response to a result of the determination.

A method of programming a nonvolatile memory device comprises programming memory cells connected to a first wordline, programming memory cells connected to a second wordline, programming memory cells connected to a third line between the first wordline and the second wordline, and adjusting a threshold voltage of the memory cells connected to the first wordline to compensate for interference generated by the programming of the memory cells connected to the third wordline.
Abstract:
An image sensor includes a pixel array including a plurality of pixels which are arranged in a matrix of a plurality of rows and columns and each of the plurality of pixels being configured to convert intensity of incident light into an electrical image signal; and an extended counting analog-to-digital converter configured to perform a first analog-to-digital conversion to provide a digital signal from an output signal of the pixel array, to obtain a residue using the output signal of the pixel array and the digital signal, and to perform a second analog-to-digital conversion using the residue.
Abstract:
An air conditioner is disclosed. Herein, the air conditioner can maintain the ambient air of a specific space (or area) to a pleasant state by adequately adjusting the temperature, humidity, and air current distribution within the corresponding space to allow people to pleasantly carry out their everyday activities. Since unwanted insects can be repelled or eliminated by using ultrasonic waves that do not contaminate the indoor air, the air conditioner can protect the human body from unwanted insects or pests while maintaining the air within the indoor space to a clean state. Also, carbon dioxide and specific light rays preferred by mosquitoes are used to attract unwanted insects into the main body, thereby eliminating the attracted insects by using ultrasonic waves. Thus, unwanted insects and, more particularly, mosquitoes existing in the room that is to be air-conditioned may be quickly eliminated.
Abstract:
Disclosed is a method of extracting a text area, the method including generating a text area prediction value within an input second image based on a plurality of text area data stored in a database including geometric information about a text area of a first image, generating a text recognition result value by determining whether a text is recognized with respect to a probable text area within the input second image, and selecting a text area within the second image by combining the generated text area prediction value and text recognition result value.
Abstract:
An optical measuring apparatus and method for a stereoscopic display device are capable of measuring optical characteristics of the stereoscopic display device. The optical measuring apparatus includes a test image supplier for generating a 3D test signal, a 3D display for displaying left-eye image and/or right-eye image based on the 3D test signal supplied from the test image supplier, an image selection member for selectively transmitting the left-eye image and right-eye image to be displayed on the 3D display, and a light measuring device that measures luminance of the image transmitted via the image selection member and calculates 3D image crosstalk of the left eye image and the right eye image based on the measured luminance.

The backlight unit comprises a light guide plate receiving light and outputting the light, a light emitting unit comprised at an one end portion of the light guide plate, a fixing frame comprising an opened interior, in which the light emitting unit and the light guide plate are comprised in the opened interior, and a reflection frame comprised at an outer side of the fixing frame and reflecting leaked light.
Abstract:
Provided are a thimble-type intermediation device and a method for recognizing a finger gesture using the same. The thimble-type intermediation device includes: a motion sensing unit sensing a motion of a user's finger and generating the sensed result as motion data; a tactile sensing block sensing a tactile behavior of the user's finger and generating the sensed result as tactile data; a control unit recognizing the gesture and tactile behavior of the user's finger on the basis of the generated motion data and tactile data, and outputting the recognition result as recognition result information; and a wireless communication unit transmitting the recognition result information to a robot system.
Abstract:
A memory device and a memory data determination method are provided. The memory device may estimate a threshold voltage shift of a first memory cell based on data before the first memory cell is programmed and a target program threshold voltage of the first memory cell. The memory device may generate a metric of a threshold voltage shift of a second memory cell based on the estimated threshold voltage shift of the first memory cell. Also, the memory device may determine data stored in the second memory cell based on the metric.
