  • Patent number: 11953382
    Abstract: A system comprising a device or the device itself for measuring temperatures, comprising a sensor array plate, comprising on a first surface at least one temperature sensor arranged on at least one tongue that is surrounded by a cut-out leaving a bridge to the sensor array plate, wherein the at least one sensor has on both sides' spacer and a second surface opposite the first surface for connection to at least one operating plate of a thermocycler; and a pressure plate, comprising fins at the side for connection to the sensor array plate that align with the spacer of the sensor array plate when a pressure plate is arranged onto a sensor array plate.
    Type: Grant

  • Patent number: 6188473
    Abstract: The invention relates to a method and a system for photodetection in which measurement signals during photon-counting operation and current operation can be tapped off in parallel at a photomultiplier through two channels, one of which is a photon-counting (pulse-counting) channel and the other an analog signal transfer channel. The signals are stored continuously and processed in a microprocessor. The two-channel operation allows the dynamic range of the photomultiplier to be expanded, in which, for each time interval, the measured value for the light to be measured is selected on the basis of an adjustable range limit from the channel that operates as a photon counter or the channel that is operated in the current mode.
