  • Publication number: 20240271815
    Abstract: A method is provided for determining whether a future time period for performing a future process run is satisfactory. The process run employs process equipment disposed within an interior space. In a first step a relationship is obtained between an environmental condition within the interior space and an environmental condition exterior to the interior space. In a second step a future value representative of the environmental condition exterior to the interior space during the future time period is obtained. In a third step a predicted value representative of the environmental condition within the interior space during the future time period is determined by comparing the future value obtained in step (b) to the relationship obtained in step (a). Next the predicted value determined in step (c) is compared to a reference. It is then determined from the comparison whether the future time period for performing the future process run is satisfactory.

  • Patent number: 11905547
    Abstract: A dry reagent composition that includes an active redox enzyme that oxidizes an analyte as a specific substrate to produce an inactive reduced form of the enzyme; and a salt of ferricyanide provides improved performance in electrochemical test strips such as those used for detection of glucose. The salt of ferricyanide consists of ferricyanide and positively-charged counter ions, and the positively charged counter ions are selected such that the salt of ferricyanide is soluble in water, and such that the salt of ferricyanide or the crystalline phase of the salt of ferricyanide has a solubility in water and/or a lower E0eff at a concentration of 100 mM than potassium ferricyanide. For example, the salt of ferricyanide may be tetramethylammonium ferricyanide.

  • Publication number: 20230419225
    Abstract: A method for determining whether a given run of a process having a defined protocol is on a trajectory for successful completion is provided. The method includes the step of initiating a run of the defined protocol of the process. During the initiated run, obtaining information reflecting variables that may affect the quality of the process. A preferred trajectory model for achieving a successful implementation of a process is also obtained. The information reflecting the variables that affect the quality of the process are compared with the preferred trajectory model. This comparison allows a determination of offset of the value of the determined variables to the value of the same variables of the preferred trajectory model. The magnitude or amount of offset is indicative of the whether the run initiated in step is on a path or trajectory for success.

  • Publication number: 20230368635
    Abstract: Determining, generating, and issuing a contextual alert message to a user regarding an alert condition of a process system is provided. Described is determining variable data from a sensor associated with a process system, transmitting a first set of variable data from the sensor to a server and using the server to develop an alert classification model using the first set of variable data, where the alert classification model contains contextual information about an alert condition of the process system, transmitting a second set of data from the sensor to the server and using the server to compare the second set of data to a threshold value to determine if the process system is in an alert condition or approaching an alert condition.

  • Patent number: 11719687
    Abstract: A method for obtaining information encoded on an electrochemical test strip is provided. The test strip has two electrodes disposed within a sample space and the information is encoded on the test strip prior to introduction of liquid sample. The method includes the step of introducing sample to the sample space so that the sample is in contact with the two electrodes within the sample space. In another step a value is determined that is representative of the double layer capacitance of the test strip and/or the equivalent capacitance of the test strip. The determined value is then translated into information reflecting a characteristic of the test strip prior to introduction of sample.

  • Patent number: 11408849
    Abstract: The presence of oxygen or red blood cells in a sample applied to an electrochemical test strip that makes use of a reduced mediator is corrected for by an additive correction factor that is determined as a function of the temperature of the sample and a measurement that reflects the oxygen carrying capacity of the sample. The measured oxygen carrying capacity can also be used to determine hematocrit and to distinguish between blood samples and control solutions applied to a test strip.

  • Patent number: 11346803
    Abstract: A test strip and analytical apparatus have pin connections permitting the definition of geographic regions or of particular customers. A test strip made for use in a particular region or for a particular customer will have pin connections matching features of the apparatus made for use in that region or by that customer. Insertion of the strip into the apparatus does not merely turn on the apparatus, but provides the regional or customer coding. Analog switches within the apparatus allow coding of a larger number of distinct regions or customers than would otherwise be possible, all without degrading the quality of the measurements made of the fluid being tested. Conductive paths in the strips permit testing the strips during manufacture so as to detect quality lapses regarding the printing or deposition of the paths.
