  • Publication number: 20200227894
    Abstract: A light source comprises a GeSn active zone inserted between two contact zones. The active zone is formed directly on a silicon oxide layer by a first lateral epitaxial growth of a Ge germination layer followed by a second lateral epitaxial growth of a GeSn base layer. A cavity is formed between the contact zones by encapsulation and etching, so as to guide these lateral growths. A vertical growth of GeSn is then achieved from the base layer to form a structural layer. The active zone is formed in the stack of base and structural layers.

  • Patent number: 10709904
    Abstract: An apparatus for performing nanoparticle-assisted external beam radiotherapy includes an X-ray spectrometer having an optical axis, an X-ray filter, and a mobile holding structure for holding the X-ray filter and X-ray spectrometer in a first and second relative position, and for switching from the first to second relative position while simultaneously positioning a patient body part in a target region including a target point. An X-ray beam emitted from the X-ray source crosses the X-ray filter before reaching the target point. The propagation of the X-ray beam forms an angle different from 0° and 180° with the optical axis of the X-ray spectrometer. The second relative position is obtained by inverting the relative positions of the X-ray filter and X-ray spectrometer relative to the patient body part. A method of determining an X-ray dose delivered at a region of a patient body using the apparatus is provided.

The characteristic indicator may be an average amplitude. The feedback device can use an error signal corresponding to the difference between the calculated characteristic indicator and a predetermined value.

  • Publication number: 20200220751
    Abstract: The present invention relates to a wavelet bandpass sampling method, with low aliasing and a corresponding device. The analogue signal to sample is correlated with a sequence of wavelets succeeding each other with a rate fp of which the positions in the sequence are temporally modulated from arguments of a CAZAC sequence, notably a Zadoff-Chu sequence. The correlation results are next sampled at a frequency fs?fp and digitally converted to provide a compressed representation of the signal. The temporal modulation of the positions of the wavelets makes it possible to obtain incoherent aliasing of the correlation signal in the sampling band and thereby to reduce aliasing.
