Abstract: A method for the time-differentiated detection of a spectrum of a test object comprises providing a first conversion dye, which is configured to convert light with a first spectral distribution in the visible range into light with a second spectral distribution in the infrared range. The first conversion dye is excited with a light pulse in the range of the first spectral distribution during a first time period, and a light fraction, reflected or transmitted by the test object, in the range of the first spectral distribution is registered during a first time interval. During a subsequent second time period, a fraction of converted light reflected or transmitted by the test object is registered. According to the invention, the first time interval is selected so that it lies substantially inside a luminescence lifetime for the first conversion dye in the first time period.

Abstract: In a heating appliance comprising a substrate for receiving an item of cookware, a method of measuring reflectivity comprises emitting a time-varying electromagnetic signal from a first side of the substrate, a portion of the time-varying electromagnetic signal propagating through the substrate. Electromagnetic radiation is then received at the first side of the substrate, the received electromagnetic radiation comprising a background ambient component received and a component reflected by the substrate. A gain factor is applied to translate the received electromagnetic radiation to a receive electrical signal. An offset signal component is then identified from the receive electrical signal, the offset signal component arising from the background ambient component of the received electromagnetic radiation. The gain factor from the offset signal component is then estimated using a characterisation of the offset signal component, and the reflectivity is calculated using the receive electrical signal and the estimated gain factor.

Abstract: A method for a wearable device to determine a biological parameter of a tissue of a person. To apply an emitting of a first and a second wavelength of light towards the tissue. To collect and sense a first and a second set of frequency bands from the signals received back from the first and the second wavelengths respectively. The first set of frequency bands represents a first signal which corresponds to a combination of the biological parameter and an extraneous noise. The second set of frequency bands represents a second signal mainly comprising the extraneous noise. To subtract the first set of frequency bands from the second set of frequency bands in the frequency domain to obtain a third set of frequency bands. The third set of frequency bands represents a third signal corresponding to the biological parameter.
