Disclosed herein is a nailer having an improved safety device. With the improved safety device, a movable plate, which is adapted to slidably move along a lower surface of a guiding unit, is formed, at a certain location thereof, with an insertion hole for the insertion of a protrusion formed at a trigger. Thereby, if the trigger is pulled in a pressed state of the movable plate, a nailing operation is accomplished. Also, in the course of pulling the trigger, the movable plate can be further inserted rearward by a predetermined distance under interaction of the insertion hole and protrusion. This has the effect of eliminating the risk of causing scratches on a nailing surface of a target structure even if the movable plate is moved while coming into close contact, at a front end thereof, with the nailing surface, resulting in several advantages, such as for example, easy nailing operation, operator's convenient working posture, and rapid and safe nailing operation.

The present invention relates to a traffic information providing apparatus and an operating method. The method includes receiving real time traffic information, storing sectional traffic information, dividing screen information currently displayed on the display unit into unit areas, selecting the unit areas sequentially, detecting additional traffic information on the corresponding unit areas from the sectional traffic information stored in the step of storing according to information on the selection, and displaying the additional traffic information. Accordingly, the present invention aims to decrease the danger of traffic accidents and provides convenient selection of search location for real time traffic information to a user.
摘要:
An apparatus and method for determining position information of a mobile station (MS). The apparatus directly estimates a propagation delay error by measuring a signal strength of a propagation signal for use in a mobile communication system, and reduces a MS position error. The apparatus reduces the MS position error by either combining the propagation signal for the mobile communication system with a GPS signal or using only the propagation signal. The apparatus receives Mobile Station (MS) position acquisition signals from the mobile communication system in order to estimate position information of the MS. The position signal acquisition unit receives the MS position acquisition signals, acquires a position signal from the received MS position acquisition signal, and outputs an acquired position signal. The primary position calculator calculates a primary position using the acquired position signal received from the position signal acquisition unit. The propagation delay error range setup unit determines a propagation delay error range using the acquired position signal. The propagation delay error estimator estimates a propagation delay error using the determined propagation delay error range and the primary position. The position calculator calculates a secondary position using the propagation delay error estimation value received and the calculated primary position.
摘要:
A step detecting apparatus and method in a personal navigator where acceleration signals in at least two directions are acquired from an accelerometer sensor, as a pedestrian moves. Variances of the acceleration signals are calculated and summed. The variance sum is compared with a threshold. If the variance sum is greater than the threshold, it is determined that a detected step is a walking step. If the variance sum is less than the threshold, it is determined that the detected step is a mark-time step.

An apparatus and method for determining a location of a movement distance measuring apparatus are provided. The apparatus and method determine whether the movement distance measuring apparatus is mounted at the waist of a pedestrian or is located in a pocket and uses a different step length estimation algorithm, e.g. a different step length estimation parameter coefficient, corresponding to the determined mounting position. The determination of whether the movement distance measuring apparatus is mounted to the waist of a pedestrian or is located in a pocket is performed on the basis of a gyro sensor.

A method for generating driver assistance information of a traveling vehicle. The method can restructure traveling environments into an image based on a sensor system capable of removing blind spots around a traveling vehicle, and a scheme capable of exactly detecting a lane and a vehicle, and give a collision warning when there is a possibility of collision. Further, the method integrates recognition results of front/rear vehicles based on a lane recognition method applicable to various road environments, including the shape, curvature and loss of a lane, improves the stability of lane recognition, and distinguishes a solid line from a dot line, so it is possible to provide a driver with the subdivided degrees of danger. In addition, when a vehicle deviates from a lane, a voice warning may be output and the position of the vehicle for a road is restructured as an image.
