Abstract:
A variable resistance memory device includes a plurality of first conductive layer pattern, a plurality of second conductive layer patterns over the first conductive layer patterns, and a plurality of lower cell structures including a switching element and a variable resistance element, the lower cell structures being formed at intersections at which the first conductive layer patterns and the second conductive layer patterns overlap each other. The first conductive layer patterns, the second conductive layer patterns and the lower cell structures serves as one of a memory cell, a first dummy pattern structure and a second dummy pattern structure. The first dummy pattern structure is formed on both edge portions in the first direction, and the second conductive layer pattern of the first dummy pattern structure protrudes in the first direction from a sidewall of the lower cell structure thereunder, and the second dummy pattern structure is formed on both edge portions in the second direction, and the first conductive layer pattern of the second dummy pattern structure protrudes in the second direction from a sidewall of the lower cell structure thereon. Failures of the variable resistance memory device due to the etch residue may decrease.
Abstract:
Method, system and non-transitory computer-readable medium for fail-safe performance of a lane centering system. An electrical power steering (EPS) system of a vehicle is monitored for a failure and operation of the lane centering system is switched to a differential braking controller to output differential braking commands to a differential breaking system upon determining that a failure of the EPS system has occurred, where the output braking commands direct the differential braking system to apply force a brake for a wheel of vehicle, such by the applied braking force the vehicle follows a desired path determined for a lane centering operation.
Abstract:
A method, system and computer readable medium to autonomously keep a vehicle in a lane. The method including, engaging a lane centering system configured to maintain the vehicle within the lane, at a specified lane position. Further engaging a lane keeping system when the lane centering system fails to keep the vehicle within the lane, the lane keeping system configured to return the vehicle to the lane, when the vehicle leaves or is leaving the lane. And, applying a cost function to determine the nature of engagement of the lane keeping system to return the vehicle to the lane.
Abstract:
Vehicle steering measurements of a vehicle may be measured. Expected vehicle steering measurements may be calculated, each calculated expected vehicle steering measurement corresponding to one of the measured vehicle steering measurements. At least one difference between one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement may be calculated. A lower boundary and an upper boundary of at least one override transition zone, each of the override transition zones corresponding to one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement, may be calculated. Steering control of the vehicle may be gradually transferred from an automatic vehicle control system to a driver of the vehicle over a predetermined period of time when one or more of the calculated differences lie between the calculated lower boundary and the calculated upper boundary of the corresponding override transition zone.

Abstract:
Provided is a drone with a wind guide part, which is configured such that it can lift off or aviate using the flow of wind. The drone has a lift force by wind discharged towards the ground through a connecting duct and a wind guide part, so that the drone may lift off or aviate using the flow of the wind. Further, the drone may aviate without a propeller, thus preventing an accident due to the contact of the propeller, saving maintenance cost, and reducing weight and noise.
Abstract:
An apparatus and method for uplink (UL) power control in a broadband wireless access (BWA) communication system are provided. In a communication method for a base station (BS), the channel gain, noise power and speed of each MS are determined, and the maximum allowable power of each mobile station (MS) are calculated using the determined channel gain, noise power and speed of each MS. Because the UL power is controlled according to the speed of the MS and the distance from the BS, the method can provide higher system capacity than the conventional power adaptation scheme.
Abstract:
A coupling capacitor and a semiconductor memory device using the same are provided. In an embodiment, each memory cell of the semiconductor memory device includes a coupling capacitor so that a storage capacitor can store at least 2 bits of data. The coupling capacitor has a capacitance having a predetermined ratio with respect to the capacitance of the storage capacitor. For this, the coupling capacitor is formed by substantially the same fabrication process as the storage capacitor. The predetermined ratio is obtained by choosing an appropriate number of individual capacitors, each with the same capacitance of the storage capacitor, to comprise the coupling capacitor. Also, the coupling capacitor is disposed on an interlayer insulating layer that buries a bit line in a cell region and a sense amplifier in a sense amplifier region.

One or more vehicle steering measurements of a vehicle may be measured. One or more expected vehicle steering measurements may be calculated, each calculated expected vehicle steering measurement corresponding to one of the measured vehicle steering measurements. At least one difference between one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement may be calculated. A speed of the vehicle may be measured. One or more current threshold values may be calculated based on the measured speed, each of the current threshold values corresponding to one of the measured vehicle steering measurements and its corresponding calculated expected vehicle steering measurement. An automatic vehicle control system may be deactivated when one or more of the calculated differences exceeds its corresponding current threshold value.
Abstract:
A method and system may include obtaining a time to complete a lane centering maneuver for a vehicle traveling on a roadway. A lane centering path may be calculated for the maneuver, based on a sensed current heading of the vehicle relative to a sensed center line as determined by the time to complete. A steering adjustment required for the vehicle to execute the maneuver with respect to the calculated lane centering path may be calculated and applied to the vehicle.
