Abstract: The invention provides a high resolution, wide dynamic range, multi-color detection platform for microfluidic analyzers/instruments and methods. The detection platform uses multiple high gain semiconductor optical sensors for the detection of luminescence from cellular or biological samples. The digitized outputs from these sensors are combined and weighted in a signal processing unit, using pre-determined algorithms for each color, which optimize the resolution in each of these high gain semiconductor optical sensors while extending the dynamic range of the detection platform.

Abstract: A position of a lens is detected by detecting, using a phototransistor, light that is emitted from a photodiode and that varies depending on lens position. A control unit divides a moving range of the lens into a plurality of areas, approximates a relationship between lens positions and current of the phototransistor for each of the areas, corrects a current of the phototransistor using the approximated relationship so as to obtain a corrected detection current having a linear relationship with respect to lens positions, and detects the position of the lens using the obtained corrected detection current.

Abstract: The output of an avalanche photodiode (APD) comprises a “photocurrent” component comprising photon initiated events resulting from the interaction of photons with the APD and a “dark current” component comprising dark carrier events arising in the APD even when the APD is not exposed to light. Differences in the pulse height distributions of photon initiated events and dark carrier initiated events are used to statistically discriminate between photocurrent and dark current components of APD output.

Abstract: A position detector includes a source of radiant energy, such as infrared light. A sensor is spaced from the source. The source and the sensor can be carried spaced apart from one another by a housing. Control circuits, carried by the housing, are coupled to the source and the sensor. Pulsed radiant energy, emitted by the source is incident on the sensor only when transmitted by a solid optical medium which has a predetermined orientation relative to the housing. When the medium has the predetermined orientation, the sensor receives transmitted radiant energy from the source. When the medium moves from the predetermined orientation, the sensor ceases to receive the transmitted radiant energy from the source, and the control circuits can generate an alarm indication.

Abstract: Ambient light is detected by a photodiode circuit by measuring the time taken for a digital output of the photodiode circuit to change state in response to exposure of a photodiode of the photodiode circuit to that ambient light. A nominal time for state change is calculated based on photodiode circuit characteristics. Furthermore, an effective time for the photodiode circuit digital output to change state is determined in a calibration mode where the photodiode has been disconnected and a reference current is applied to the circuit. An illumination value of the detected ambient light is then calculated as a function of: the measured time, the effective time and the nominal time.
