Abstract: A monitoring system is presented for monitoring quality of fluid in a fluid chamber. The system includes: a sensing system which comprises sensing units of different types configured to measure multiple parameters of the fluid and generate corresponding measured fluid quality data and to perform self-diagnostic of an operational condition of the sensing system and generate sensing data indicative of sensing quality, and a control system comprising a local controller configured to be responsive to data indicative of a relation between the measured fluid quality data and the sensing quality and selectively generate operational data to initiate one or more of the following: generation of alarm signal indicative of an abnormal condition of the quality of the fluid, correction of the measured fluid quality data in accordance with the sensing quality; and replacement of one or more elements of the sensing units.

Abstract: A portable blood chemistry monitoring meter that employs an analog circuit in conjunction with a manually adjustable potentiometer to locate a null position that balances the measure taken of the blood chemistry-induced changes in the chemistries of disposable test strips. The meter displays in pre-printed, man-readable format blood chemistry concentrations that are individually calibrated to the specific batch-lot chemistries of the disposable test strips used with the meter. In a preferred embodiment, the meter is a blood glucose monitoring meter.

Abstract: An optical fluid tester device for testing a fluid sample in an ampoule includes an ampoule cradle, a radiation source, a radiation detector and an analyzer. The ampoule cradle supports the ampoule. The ampoule with the fluid sample serves as a lens whose focal properties are dependent on the index of refraction of the fluid sample. The radiation source irradiates the ampoule. The radiation detector is located opposite the radiation source so that the ampoule, when supported by the ampoule cradle, lies between the radiation source and the radiation detector. The detector serves to detect the intensity of the incident radiation. The analyzer verifies the composition of the fluid sample based on the detected intensity, which is dependent on the focal properties of the ampoule and is, therefore, indicative of the composition of the fluid sample.
