  • Patent number: 11137347
    Abstract: The invention is used to ascertain a sun protection factor for light, for example for cosmetics and sunscreens for which a sun protection factor (SPF) is specified. Two measurements of the light backscattering on the skin surface are carried out in vivo or in vitro or on skin models (animal skin models or artificial skin models) before and after applying the radiation protection means onto the skin, and the sun protection factor is ascertained therefrom. In contrast to standard methods used until now, the distance between the lighting surface and the detection surface on the skin is ascertained for the irradiation path of the measurement method. The skin lighting dose used during the measurement lies below harmful limits. The sun protection factor can be ascertained according to previous standards or for additional wavelengths or wavelength ranges (e.g. UVA, VIS, NIR, IR).

  • Patent number: 10854523
    Abstract: A semiconductor device according to the present invention includes: a substrate; a heat generating portion provided on the substrate; a cap substrate provided above the substrate so that a hollow portion is provided between the substrate and the cap substrate; and a reflection film provided above the heat generating portion and reflecting a medium wavelength infrared ray. The reflection film reflects the infrared ray radiated to the cap substrate side through the hollow portion due to the temperature increase of the heat generating portion, so that the temperature increase of the cap substrate side can be suppressed. Because of this function, even if mold resin is provided on the cap substrate, increase of the temperature of the mold resin can be suppressed.

  • Patent number: 10823775
    Abstract: Methods and apparatus for sensing or measuring an electromagnetic field. The method entails excitation into a distribution of Rydberg states of atoms of a gas occupying a test volume coextensive with the electromagnetic field. Transmission along a path traversing the test volume of at least one probe beam of electromagnetic radiation is measured at one or more frequencies overlapping a spectral feature, and a physical characteristic of the electromagnetic field is derived on the basis of variation of the spectral feature. In various embodiments, the electromagnetic field may be place in interferometric relation with another electromagnetic field. Time-varying electric field amplitude, frequency, phase and noise spectral distribution may be measured, and thus AM and FM modulated fields, as well as magnetic fields of about 1 Tesla. The apparatus for measuring the electromagnetic field may be unilaterally coupled to a probe field and detector or array of detectors.

  • Patent number: 10802181
    Abstract: Laser energy has a non-uniform energy distribution in its profile such that at least one first portion of the laser energy is more intense than at least one second portion of the laser energy. The laser energy is absorbed using a beam dump having an absorbing surface, which converts the laser energy into thermal energy. A shape of the absorbing surface is based on the profile. At least one first portion of the absorbing surface has one or more first angles of incidence with respect to the laser energy and receives the first portion(s) of the laser energy. At least one second portion of the absorbing surface has one or more second angles of incidence with respect to the laser energy and receives the second portion(s) of the laser energy. The one or more first angles of incidence are larger than the one or more second angles of incidence.
