The tray includes a calibration test pattern affixed or printed thereon placed proximate to the test device and in alignment with the axis of the test device. As the tray is closed and the test device is inserted to the reader, the calibration test pattern is first read by an optics unit including a photodiode. The resulting photodiode output provides a calibration curve S that the reader then uses to correct for any non-linear response of the reader's optical or electronic systems, thus insuring that every reader will yield the same readout for a given test cartridge, despite reader-to-reader variations or reader degradation with time. One use of the reader is for detection of SARS-CoV-2 infection.

  • Patent number: 10761115
    Abstract: A sensor detects a detected value for a covered wire without metallic contact, and includes: a tubular support that has a male thread and an insertion channel in which the covered wire is inserted and supported; a tubular shell that is inserted into the support from a base end; a pillar-shaped detection electrode that is inserted in and supported by the shell; and a tubular threaded piece that screws onto the male thread, is rotatably attached onto the shell, and is moved, along the axis of the support, together with the shell and the detection electrode by a screwing operation. The detection electrode is configured so that the front surface is pressed onto the covered wire in the support when the detection electrode moves, resulting in the front surface becoming capacitively coupled to a core wire of the covered wire via an insulating covering.

  • Patent number: 10680056
    Abstract: A method of fabricating an integrated circuit (IC) includes providing a substrate having a semiconductor surface layer comprising an unpatterned resistive layer. Measurements are obtained of a characteristic of the unpatterned resistive layer at each of a plurality of locations over the substrate. The unpatterned resistive layer is modified, such as by targeted removal of layer material, in response to the measurements such that the measured characteristic is more uniform across the substrate. A resistor on the IC is defined from the unpatterned resistive layer after the modifying.

  • Patent number: 10436708
    Abstract: Described is a method for quantifying the amount of optically interfering gas impurities in a gas detection system comprising a sample gas inlet, a reference gas inlet, a gas modulation valve, and an infrared absorption gas detector used for analysis of methane or natural gas, wherein the gas modulation valve alternatingly connects the sample gas inlet to the gas detector during a sample gas time period and the reference gas inlet to the gas detector during a reference gas time period. The method includes measuring an infrared absorption for at least two different sample gas concentrations in the gas detector achieved via respective different ratios from the sample gas time period and the reference gas time period, and comparing amplitudes of different measurement signals of the at least two different sample gas concentrations with calibration functions to assess an actual gas impurity concentration in the sampled gas.

  • Patent number: 10371680
    Abstract: A gas sensor is provided with a metal shell protecting member formed of a material superior in heat resistance to a metal shell, whereby a high-temperature measurement target (exhaust gas) is prevented from being in direct contact with a region, of a protector internal region of the metal shell, on the front side relative to a protector opposing surface. That is, in the gas sensor, it is possible to suppress corrosion, due to high temperature, of a region, of the protector internal region of the metal shell, on the front side relative to the protector opposing surface (an inner surface and a front end surface of a protector fixing portion), while the metal shell is formed of a material (SUS430) that can be subjected to working (crimping or the like) accompanied with deformation. Therefore, heat resistance of the entire sensor can be improved.
