Abstract: A microfluidic controller and detector system and method for performing screening assays are disclosed. The microfluidic controller and detector system comprises a fluidic chip that includes at least two intersecting channels and a detection zone, a fluid direction system comprising an electrical interface configured for electrical contact with the at least two intersecting channels, an optics block having an objective lens disposed adjacent the detection zone, and a control system coupled to the optics block and adapted to receive and analyze data from the optics block. The electrical interface generally includes electrodes configured for electrical contact with the intersecting channels and coupled to electrode channels for supplying electrical input to the electrodes. A reference channel is optionally provided to calibrate the electrode channels.

Abstract: The present invention provides various methods for detecting errors in a blood analysis system. The system includes a blood analyzer and a molded plastic rotor with a series of chambers and capillary channels through which blood is processed and distributed to cuvettes which contain lyophilized reagents. The rotor is placed in the analyzer which spins the rotor, and an optical system reads the cuvettes as light is flashed through the cuvettes.

Abstract: An inclinometer 300 includes a sensing unit 302 for providing a signal dependent on the orientation of the inclinometer 300. The inclinometer 300 includes a rescaling unit 322 which improves the performance of the inclinometer providing additional compensation for any change in the sensor 302 over time and temperature. The inclinometer 300 further includes an angle offset function 91, 360 which provides a permanent angle offset to any angle determined by the inclinometer.

Abstract: An inclinometer 20 has a sensing unit 40 for providing a varying capacitance signal depending on the orientation of the inclinometer 20. An oscillator circuit unit 82 includes the sensor unit 40 as a capacitive element for providing a signal having a period and a frequency depending on the capacitance of the sensor unit 40. A unit 92 is provided for determining the period of the signal. A look-up table unit 96 stores a predetermined relationship between the period of the signal and the angle of orientation of the inclinometer 20. A comparison unit 94 then compares the period of the signal to the period stored in the look-up table unit 96 and selects the corresponding angle which is the angle of orientation of the inclinometer 20. The angle is then displayed on the inclinometer display 25.
