  • Patent number: 11703504
    Abstract: An electrochemiluminescence method of detecting an analyte in a liquid sample and a corresponding analysis system. An analyte in a liquid sample is detected by first providing a receptacle containing a fluid comprising protein coated magnetic microparticles to a stirring unit. Stirring of the fluid is necessary since the density of the microparticles is usually higher than the density of the buffer fluid. Thus the microparticles tend to deposit on the bottom of the receptacle leading to an aggregation of the microparticles because of weak interactions. To obtain representative measurements a homogeneous distribution of the microparticles in the buffer fluid is necessary to ensure a constant concentration of microparticles for each analysis cycle. It is further necessary to provide disaggregation of the microparticles, which is also realized by stirring the fluid. Stirring is conducted with a rotational frequency that is adapted to the amount of fluid to be stirred.

  • Publication number: 20230197031
    Abstract: To enable uncompressed RAW data to be appropriately transmitted from an imaging device to an external device. A transmission unit transmits uncompressed RAW data to an external device via a transmission path. In a case where the external device does not support the uncompressed RAW data, the control unit controls the transmission unit so as not to perform output processing for outputting the uncompressed RAW data to the transmission path. For example, the information reception unit receives identification information indicating that the external device supports the uncompressed RAW data from the external device via the transmission path.
