Abstract: A method of determining auto-calibrating information of a test sensor includes providing an optical read head that includes a light source, a light guide and a detector. The read head forms an opening that is sized to receive a test sensor. The detector includes a linear-detector array or single detector. A test sensor is provided having apertures formed therein. The test sensor is placed in the opening of the optical read head. Light is transmitted from the light source through the apertures. The light transmitted through the apertures using the detector or detecting the absence of light being transmitted through the test sensor using the detector is detected. The detected light or the absence of detected light information from the detector is used to determine the auto-calibration information of the test sensor.

Abstract: An in-situ technique is provided for automatically verifying proper operation of a photometric device, such as a cell density probe (CDP). The CDP has a first detector and a second detector. The first detector senses light that is transmitted from a light source of the CDP. The second detector senses light that has passed through an optical gap at a tip of the CDP, wherein the sensed light has been reduced in intensity due to light absorption. Electrical current provided to the light source is reduced, and the resultant values of a light characteristic (such as intensity) are sensed. These values from the detectors are compared against one or more predicted values. If the CDP is operating properly, the values from the detectors will be consistent with the predicted values. If there is a malfunction in the CDP, then the values from the detectors will be inconsistent with the predicted values.

Abstract: An optical monitoring system for determining the constituents of a sample or specimen. An absorption spectrum is obtained from a sample and is passed through one or more filters having a specified absorption spectrum defined by a single atom or a compound. If the filter's absorption spectrum is included in the sample's absorption spectrum, then the sample contains that atom or compound. The apparatus includes a switching assembly that sequentially places one or more filters into the light path to determine if the subject atom or compound is contained in the sample.

Abstract: In-situ technique for automatically verifying proper operation of a photometric device, such as a cell density probe (CDP). In one embodiment, the CDP comprises a first detector and a second detector. The first detector (226) senses light transmitted from a light source of the CDP. The second detector (210) senses light passed through an optical gap (106) at a tip of the CDP, wherein the sensed light has been reduced in intensity due to light absorption. Electrical current provided to the light source is reduced, and the resultant values of a light characteristic (such as intensity) at the first and second detectors are sensed. Values from the detectors are compared against one or more predicted values. For proper CDP operation, the detector values are consistent with the predicted values. If there is a malfunction in the CDP, the detector values are inconsistent with the predicted values.

Abstract: Various methods for controlling one or more parameters of a flow cytometer type measurement system are provided. One embodiment includes monitoring parameter(s) of the measurement system during measurements of sample microspheres. The method also includes altering the parameter(s) in real time based on the monitoring. Another method includes monitoring a temperature proximate to the measurement system. One such method includes altering a bias voltage of an avalanche photo diode in response to the temperature using empirically derived data. A different such method includes altering output signals of a photomultiplier tube in response to the temperature using a characteristic curve. Some methods include monitoring a temperature of a fluid, in which sample microspheres are disposed, that will flow through the flow cytometer type measurement system. This method also includes determining a velocity of the sample microspheres in the measurement system from a viscosity of the fluid at the temperature.
