摘要:
Differential current driving type transmitter and receiver, and an interface system having the transmitter and receiver. The transmitter includes a current source, a current direction selecting block, and a balancing switch block. The current source sources currents to a pair of transmission lines or sinks currents flowing through the pair of transmission lines. The current direction selecting block transfers a current flowing from the current source to one transmission line of the pair of transmission lines and a current flowing through the other transmission line of the pair of transmission lines to the current source. The balancing switch block initializes the pair of transmission lines to a balanced state.

Disclosed herein is a power semiconductor module. The module includes metal plates each having a first through hole, with an anodic oxidation layer formed on a surface of metal plates and an interior of the first through hole. A cooling member has a second through hole at a position corresponding to the first through hole, and the metal plates are attached to both sides of the cooling member. A circuit layer is formed on the anodic oxidation layer and performs an interlayer connection through a via formed in the first and second through holes. A power device is connected to the circuit layer. A resin encapsulant encloses the circuit layer and the power device. A housing is installed to each of the metal plates to form a sealing space for the resin encapsulant.

A reaction cassette for a glycated hemoglobin meter and a measuring method thereof are provided. The reaction cassette for the glycated hemoglobin meter includes: a first zone receiving a first reagent and a blood sample; a second zone receiving a second reagent; a reaction zone in which the blood sample reacts with the first reagent, or through which the second reagent passes to react with a first blood sample mixture obtained by reacting the blood sample with the first reagent; and a measurement zone measuring an amount of total hemoglobin in the first blood sample mixture, or measuring an amount of glycated hemoglobin in a second blood sample mixture obtained by reacting the first blood sample mixture with the second reagent, wherein the blood sample, the first reagent, and the second reagent move between the reaction zone and the measurement zone according to a rotation angle of the reaction cassette when the reaction cassette is rotated. Therefore, since the reaction cassette rotates automatically, it is possible to measure the amount of glycated hemoglobin in a blood sample through simple manipulation and reduce a manufacturing time. Furthermore, since reagents are supplied to the reaction cassette from a separate reagent pack, it is possible to resolve storage and distribution problems of the reaction cassette, which occur when reagents are stored in the reaction cassette.
