20090075898 | Complement C3A Derived Peptides and Uses Thereof - Peptides corresponding partially to positions 55-64 of the sequence of the complement component peptide C3a are capable of preventing and treating mast cell- and basophil-mediated disorders by inhibiting IgE- or IgG-mediated triggering and/or by inhibiting the FcεRI- and/or FcγR-induced secretory response, while obviating the anaphylatoxic response. These peptides are useful for prevention and/or treatment of allergic disorders where mucosal-type and/or serosal-type mast cells and/or basophils are involved such as asthma, allergic dermatosis, and gastrointestinal allergies. | 03-19-2009 |

20100103487 | HOLOGRAPHIC STORAGE SYSTEM FOR READING A HOLOGRAM STORED ON A HOLOGRAPHIC STORAGE MEDIUM AND A METHOD CARRIED OUT THEREWITH - The invention relates to a holographic storage system for reading a hologram stored on a holographic storage medium. The system comprises: storage medium holding means arranged along an optical path of a reference beam; a spatial light modulator (SLM) arranged along said optical path for encoding a reference beam with a code pattern; a detector for detecting an image of the reconstructed hologram; and a servo control unit for determining a misalignment of said reference beam and said storage medium from the detected image and for acting upon said SLM to shift said code pattern. The invention further relates to a method of reading a hologram stored on a holographic storage medium comprising the steps of: a) encoding a reference beam with a code pattern created by a spatial light modulator (SLM); b) detecting an image of the reconstructed hologram; c) determining a misalignment of said reference beam and said storage medium from the detected image; and d) shifting said code pattern on the SLM based at least in part on said misalignment. | 04-29-2010 |
20100103796 | METHOD OF READING A FOURIER HOLOGRAM RECORDED ON A HOLOGRAPHIC STORAGE MEDIUM AND A HOLOGRAPHIC STORAGE SYSTEM - The invention relates to a method for reading a Fourier hologram recorded on a holographic storage medium with a holographic storage system. The method comprises the steps of: —calculating a characteristic value from a detected image of a reconstructed Fourier hologram in at least two relative positions of a reference beam and said storage medium, each of the characteristic values being indicative of a misalignment of the reference beam and said storage medium at the respective relative position, —calculating a servo value from the measured characteristic values, —determining an aligned relative position of said reference beam and said storage medium by means of a predetermined servo function using the calculated servo value, —setting the relative position of the reference beam and said storage medium to said aligned relative position, and —detecting an image at said aligned relative position. The invention also relates to a holographic storage system for reading a Fourier hologram recorded on a holographic storage medium, said system comprising reference beam generating means, storage medium receiving means and a detector for detecting a reconstructed hologram. The system further comprises a servo control unit for executing the method according to the invention. | 04-29-2010 |
20100118242 | PHASE MODULATOR SYSTEM COMPRISING A BEAM SPLITTER AND A LINEAR POLARISATION MODE PHASE MODULATOR AND METHOD FOR SEPARATING A LIGHT BEAM TRAVELLING TOWARD AND REFLECTED BACK FROM SUCH A PHASE MODULATOR - The object of the invention is a phase modulator system comprising a beam splitter and a reflection mode phase modulator suitable for modulating linearly polarised light of at least one specific polarisation state while maintaining said polarisation state. The beam splitter and the phase modulator are arranged along an optical path of a light beam. The beam splitter is a polarisation beam splitter and the phase modulator system further comprises an optical rotator being arranged along the optical path between the polarisation beam splitter and the phase modulator, and rotating the polarisation state of the light beam by | 05-13-2010 |
