摘要： A frequency reconfigurable digital filter and an equalizer using the same are disclosed. The digital filter includes a sampling kernel storage section configured to store a sampling kernel for performing upsampling of a model filter response scaled by a sampling constant and generating response of Multi images which are repeatedly formed with a constant period; a complementary conversion section configured to generate response of Multi complementary images repeatedly formed with constant period in frequency domain where the Multi images are not generated, the Multi complimentary images having the same characteristic as the Multi images; and an image response operation section configured to operate response of an image corresponding to a selected band among the Multi complementary images and the Multi images. The filter reconfigures frequency to realize various band pass characteristics only through changing very small number of parameter, and a user may change easily band of the filter.

摘要： A tracking control circuit for directly controlling the tracking (i.e., the steering) of an automatic guide vehicle (AGV) without utilizing a central processing unit (CPU) for control. The circuit controls the tracking of the AGV by comparing a first induced voltage with a second induced voltage to sense the tracking state (i.e., whether the AGV is veering right or left of the appropriate path), and then providing to a servo interface board either a voltage obtained by subtracting a reference voltage from the first induced voltage or a voltage obtained by subtracting the second induced voltage from the reference voltage. Which voltage is provided is determined in accordance with the sensed result of the tracking state.

摘要： A system is provided for transferring a substrate of a flat panel display between the processing stations of a flat panel display manufacturing line. The system includes a transfer device that transfers a transfer container in which a substrate is loaded, a container loading and unloading device that loads and unloads the containers on and from the transfer device, and a substrate loading and unloading device that transfers the substrates between the container and processing equipment located at the respective stations. The transfer device includes a track mounted on a facility floor and a plurality of wheeled carriages that move programmably along the track by means of linear motors. The system enables substrate transfer time to be reduced substantially, yet provides robust protection of the substrates throughout the transfer process.
