Phototherapy consists in applying radiation on a part of the human body in order to treat an illness. A radiation dose is established for each treatment. In order to apply the correct dose a ...treatment time is set. However, in this work we have carried out some hyperspectral imaging studies that conclude that the radiation sources and the absorption properties of each patient can change. Therefore, the same treatment time does not ensure that the patient receive the appropriate dose. Thus, an optimized therapy system must measure the radiation emitted by the source and absorbed by the patient on real time to calculate the optimal dose at which the treatment is effective. In this work, we have developed and designed a custom system to measure the effectiveness of a radiative therapy treatment to adapt the appropriate dose for a specific patient in real time.
The proposed system has been designed to identify dermatopathologies or to apply personalized phototherapy treatments. The system emits electromagnetic waves in different spectral bands in the range ...of visible and near infrared to irradiate the target (skin or any other object) to be spectrally characterized. Then, an imaging sensor measures the target response to the stimulus at each spectral band and, after processing, the system displays in real time two images. In one of them the value of each pixel corresponds to the more reflected wavenumber whereas in the other image the pixel value represents the energy absorbed at each band. The diagnosis capability of this system lies in its multispectral design, and the phototherapy treatments are adapted to the patient and his lesion by measuring his absorption capability. This "in situ" absorption measurement allows us to determine the more appropriate duration of the treatment according to the wavelength and recommended dose. The main advantages of this system are its low cost, it does not have moving parts or complex mechanisms, it works in real time, and it is easy to handle. For these reasons its widespread use in dermatologist consultation would facilitate the work of the dermatologist and would improve the efficiency of diagnosis and treatment. In fact the prototype has already been successfully applied to pathologies such as carcinomas, melanomas, keratosis, and nevi.
JEM-EUSO is a space observatory that will be located on-board the Japanese Experiment Module at the International Space Station. It will observe Extensive Air Showers (EAS) induced by ultra-high ...energy cosmic rays using the Earth's atmosphere as detector. In addition to clear sky observations, EAS are also observable in cloudy conditions if a sufficiently large part of the EAS development occurs above the cloud. The atmospheric monitoring system plays a fundamental role in our understanding of the atmospheric conditions in the field of view of the telescope.
In order to study the real on-site aging of concrete and the potential corrosion risk for the reinforcements, Enresa has undertaken a monitoring programme in collaboration with Institute of ...Construction Science 'Eduardo Torroja' (IETcc) by permanently monitoring a pilot nuclear waste container through the installation of sensors. The pilot container of medium and low radioactive waste is buried near the real large concrete cells and has been monitored from 1994. The evolution from 1995 of corrosion parameters (corrosion rate, corrosion potential, electrical resistivity, concrete strains, oxygen availability) obtained is commented in the paper. The results indicate that the parameters evolve with time and the temperature is a very relevant variable influencing the measurements. An attempt to model the effect of temperature has been made by calculating the 'apparent activation energies' for the case of the electrical resistivity. Two clear regimes or slopes were found, one below and the other above 20°C, which have been attributed to a change in the state of the water from liquid to vapour although it has not been confirmed. The fact is that the resistivity increase is more pronounced above 20°C than below.

One of the main problems related to infrared remote sensing of forest fires by automatic systems concerns the rejection of false alarms. The study of the infrared spectral radiance emitted by a ...biomass fire has been used to define spectral algorithms that permit to separate fires from other sources considered as false alarms. The different behaviour of the medium (3–5 μm) and thermal (8–12 μm) infrared spectral regions has been the basis for the definition of a new “figure” of merit, the so-called Fire Index (FI). An experimental burn has been used to test the ability of FI to identify clearly fires. A second algorithm based on an intraband analysis, the Mid-IR Fire Index (MFI), has been proposed to give complementary information to FI. Evolution of FI and MFI values with distance for different IR sources has been calculated. Finally, an experimental validation of both algorithms has been performed by using two infrared cameras working in the medium and thermal infrared spectral windows.
An Atmospheric Monitoring System (AMS) is mandatory and a key element of a space-based mission which aims to detect Ultra-High Energy Cosmic Rays (UHECR). JEM-EUSO has a dedicated atmospheric ...monitoring system that plays a fundamental rote in our understanding of the atmospheric conditions in the Field of View (FoV) of the telescope. Our AMS consists of an infrared camera and a LIDAR device that are being fully designed with space qualification to fulfil the scientific requirements of this space mission. This AMS will provide information of the cloud cover in the FoV of JEM-EUSO, as well as measurements of the cloud top altitudes with an accuracy of 500 m and the optical depth profile of the atmosphere transmittance in the direction of each air shower with an accuracy of 0.15 degree and a resolution of 500 m. This will ensure that the energy of the primary UHECR and the depth of maximum development of the EAS (Extensive Air Shower) are measured with an accuracy better than 30% and 120 g/cm super(2), for EAS occu rring either in the clear sky or with the EAS depth of maximum development above optically thick cloud layers. Moreover novel stereoscopic and radiometric retrieval techniques are under development to infer the Cloud Top Height (CTH) from the brightness temperature patterns obtained from the infra red camera.

If the elements referred to in para. 4 of Art. 5 of the Law on Trade Marks and Indications of Geographical Origin, which individually may not be registered as trade marks, have been incorporated in a ...trade mark, and registration of that mark could or might cause doubt as to the extent of the rights conferred, the Patent Office, when registering the mark, may exclude those elements from protection with a special annotation (disclaimer or exclusion from protection).
The legislator has clearly
expressis verbis
assigned the right of disclamation to the competence of the Patent Office, which may disclaim of its own motion and not at the initiative of an applicant or an opponent.
There is no provision which would require a court to exclude from protection (disclaim) an element included in a registered trade mark.
Disclamation does not constitute a declaration of invalidity of a trade mark in part and does not reduce the scope of the rights conferred by registration of the trade mark, as it in fact has merely an informative or educational function.
