Abstract: The present disclosure relates to a method and apparatus for electronic voting performed in response to insertion of an electronic ballot by a voter into an electronic voting machine. The method includes storing candidate information in a candidate database, issuing an electronic ballot by a ballot dispenser in response to a ballot issuance request of a voter, displaying by the electronic voting machine a list of candidates from the candidate database when the electronic ballot is inserted into the electronic voting machine, and printing by a printer vote data related to a selected candidate on the electronic ballot, followed by dispensing the printed electronic ballot when the voter selects the candidate whom the voter wishes to vote from among the list of candidates. The electronic ballot is printed with a barcode corresponding to vote information containing at least one of data for authentication, precinct ID and polling place ID.

Abstract: Provided is a locking mechanism for a flat display device. The locking unit for a single axis rotation flat display device in which an upper body and a lower body are coupled to each other by a rear main hinge, includes: a latch member movable on a guide disposed in the upper body, a locking hole formed in the latch member and a bent portion slantingly bent at a lower end of the latch member which is made of a ferromagnetic material. In a retracted state, the latch member is substantially disposed within the upper body, while in deployed state the latch member protrudes therefrom. A restoration member provides a restoration force to the latch member so as to urge it into its retracted state. A hook member hingedly coupled to the lower body. The hook member having a hook portion whose upper end engages the locking hole. a magnet is installed to or in proximity to the hook member under the hook portion.

Abstract: A car navigation device using a forward real video and a control method thereof are disclosed. The car navigation device using a forward real video along the travel direction of a vehicle, comprises a camera that photographs the forward real video and outputs the photographed video on a screen, a GPS receiver that receives current position information of the vehicle from a satellite, and a navigation main module that receives the current position information of the vehicle from the GPS receiver, obtains more accurate current position information through calibration using a speed sensor and a gyro, extracts TBT information based on the obtained accurate current position information and user's set destination point information by a general method, and overlays the TBT information on the screen containing the forward real video along the direction of a destination point.

Abstract: In a method of controlling data reproduction in an optical disk drive, when a decoding error occurs, decoding is performed by changing a servo parameter. Thus, the decoding errors are reduced while playability is improved. The method of controlling data reproduction in an optical disk drive for reading data stored on an optical disk is performed by monitoring whether a decoding error occurred at a host part, if a decoding error occurred, changing a servo parameter for adjusting balance and/or offset of error signal which input to servo system, and rereading a portion on the optical disk medium where the decoding error occurred using the changed servo parameter and performing decoding.

Abstract: This tilt correcting method includes the step of monitoring jitter values while adjusting a turntable or guide rail after a wobble disc is placed on the turntable. Thereafter, it is determined whether the depths of valleys of monitored jitter values are different, it is determined that the reference tilt is a radial tilt if it is determined that the depths of valleys of the monitored jitter values are different, and the radial tilt is corrected. If it is determined that the depths of valleys of the monitored jitter values are not different, it is determined whether the heights of peaks of the monitored jitter values are different, it is determined that the reference tilt is a tangential tilt if it is determined that the heights of peaks of the monitored jitter values are different, and the tangential tilt is corrected.

Abstract: This tilt servo control method includes the step of reading a first jitter value “A”. Thereafter, a second jitter value “B” is read after an angle of an objective lens is moved by a predetermined step. If “A” is equal to or smaller than “B”, the angle of objective lens is optimized by performing the tilt servo while the angle of objective lens is moved. If “A” is larger than “B”, a third jitter value “C” is read after the angle of objective lens is moved by predetermined step. If “A” is equal to or smaller than “C”, the angle of objective lens is optimized by performing the tilt servo while the angle of objective lens is moved. If “A” is larger than “C”, the angle of objective lens is optimized while the angle of objective lens is moved by half of the predetermined step.

Abstract: A clamping device of disc adapted to flatten a defective disc warped in the opposite direction (upward direction) of disc pick-up for enabling an easy reproduction of data recorded in the disc, the clamping device of disc so constructed as to allow a disc placed on a tray to be arranged between a turntable rotor mounted at a deck body and a clamp mounted at a deck cover for clamping, wherein the clamp is integrally formed with a plurality of pressing protruders at an outer periphery and disc pressing surface at an inner periphery to simultaneously press an inner non-recording surface and an outer non-recording surface of the disc accommodated on the turntable rotor.
