Provided is a multi-channel biosensor using a biosensor using a surface plasmon resonance capable of measuring the changed resonance angle in real time without additionally scanning an incident angle according to the change of temperature or external environment by including a sensor chip with a plurality of channels arranged on a top surface thereof in parallel, a light source for vertically emitting a beam from a top portion of the sensor chip to a direct bottom portion of the sensor chip, a first lens for defocusing the beam emitted from the light source in the top portion of the sensor chip, a beam splitter for splitting a reflected beam, wherein the reflected beam is obtained by reflecting the beam defocused through the first lens from each channel of the sensor chip and a sensing unit for receiving a parallel component of the beam split in the beam splitter.
Abstract:
The present invention relates to a sample analyzing apparatus for controlling the flow of a fluid by the movement of a ball using centrifugal force and inertia.Provided is a sample analyzing apparatus using centrifugal force and inertia according to the invention including a rotating body composed of a disk including upper and lower thin-films; a plurality of chambers composed of a polygonal space parts in the rotating body and including porosities on one side edge and a bottom side thereof; paths connected between the porosities of the chambers to transfer fluids mixed or separated in the chambers; sample inputting holes connected to the chambers formed inside of the rotating body through the paths; and balls moving within the chambers. Since the sample analyzing apparatus using the centrifugal force and inertia according to the invention does not require a separate device for moving the ball, the sample analyzing apparatus can be formed in a thin-film and a failure rate can be reduced by a simple technical configuration.

Abstract:
A circuit for controlling an LED with temperature compensation is employed in the LED-based system. The circuit of the invention linearly controls luminance and color of the LED according to temperature change and more precisely compensates for temperature-related variations in LED properties. Also, the circuit saves the cost of the product due to no requirement of a microprocessor. In the circuit, a waveform generator generates a sawtooth wave for Pulse Width Modulation (PWM) control. A temperature detector detects a voltage via a resistance value which is linearly variable according to changes in an ambient temperature. A PWM controller compares the sawtooth wave from the wave generator with the detection voltage from the temperature detector and generates a PWM voltage having a duty determined by the comparison result.
