  • Stove guard using a broad field of view
    Patent number: 11441845
    Abstract: A stove guard having a data processing unit and a heat sensor arrangement for receiving heat radiation from objects located in a given field of view and for delivering the detector signals indicative of the received heat radiation to the data processing unit. The heat sensor arrangement is arranged to generate detector signals differently corresponding to the heat radiation received from a central area of the field of view than to the heat radiation received from a circumferential area of the field of view.
    Type: Grant

  • Stove guard utilizing different wavelengths
    Patent number: 11248964
    Abstract: A stove guard comprises a data processing unit (101) and a temperature sensor arrangement (102) for receiving thermal radiation from objects in a specific field of view and for supplying detector signals representative of the received thermal radiation to the data processing unit (101). The temperature sensor arrangement (102) includes at least three detector elements (201, 202, 203), their sensitivity bands located at different positions along an optical radiation wavelength axis. The sensitivity band of one of said detector elements is limited to a wavelength range of less than 1.2 micrometers.
