Abstract:
The present invention has a feature to form a biocompatible dielectric thin film on the surface of a metal electrode in a biosensor constructing a biochip. When using such a biocompatible dielectric thin film, this non-specific adsorption between a protein such as enzyme and a metal electrode can be prevented. Therefore, the present invention can escape a phenomenon that inhibits the reaction of a biomolecule due to the non-specific adsorption on the surface of a metal electrode. In addition, when the dielectric thin film having a high dielectric constant, as a biocompatible dielectric thin film, is made on the surface of a metal electrode, the sensitivity of an electrical detection according to the reaction of a biomolecule can be improved.
Abstract:
A method and apparatus for transmitting data to an Access Point (AP) and a Mobile Station (MS) in a Time Division Duplex (TDD) optical repeater. A main donor generates a control frame for controlling a remote, upon receipt of data from the AP, and transmits the control frame to the remote during a non-downlink transmission period. The remote analyzes the control frame received from the main donor, detects sync information about a downlink signal and an uplink signal, and remote control information from the analyzed control frame, performs a control operation according to the detected remote control information, and generates a status frame for notifying the main donor of the status of the remote upon receipt of data from the MS. The status frame is transmitted from the remote to the main donor during a non-uplink transmission period.

A traveling system for construction equipment is provided, which can secure an initial traveling manipulability regardless of a low-speed traveling or a high-speed traveling. If the high-speed traveling is selected and the traveling is manipulated, the inclination angle of a swash plate of a hydraulic pump is variably controlled, so that the discharge flow rate of the hydraulic pump exceeds a predetermined flow rate in comparison to the low-speed traveling.
