20090312751 | LASER THERAPY DEVICE FOR THE TREATMENT OF SKIN DISEASES - The invention relates to a method for the treatment of skin diseases, in particular psoriasis, by means of UV radiation generated by a laser and directed towards the skin areas affected by the skin disease. Such method provides that the thickness of the epidermis in the skin areas is determined and the laser radiation dose regulated depending on the epidermis thickness so detected.

For the determination of the thickness of the epidermis an ultrasonic device is preferably employed. As a result of the laser radiation dose being adapted to the individual patient and individual plaque the treatment is objective is achieved earlier with the total radiation dose being reduced and less side effects occurring than experienced with comparable treatment methods known from the state of the art. Furthermore, the invention relates to a laser therapy device for the implementation of the method proposed according to the invention. | 2009-12-17 |

20090312818 | Visual Prosthesis for Control of Spatiotemporal Interactions - In a visual prosthesis or other neural stimulator it is advantageous to provide non-overlapping pulses in order to provide independent control of brightness from different electrodes. Non-overlapping pulses on geographically close electrodes avoid electric-field interaction which leads to brightness summation or changes in the shape and area of percepts. It is advantageous to apply pulses to nearby electrodes in a way that the currents do not overlap in time at all. The new finding is that even a small amount of separation results in a significant improvement as small as (ie. 0.225 msec). ‘Nearby’ is defined as within a few millimeters of each other. Another new finding is that there is some additional benefit of separating the pulses in time even further. In particular, some experiments showed a benefit of separating them more than 1.8 msec. Another experiment showed a benefit of separating them greater than 3 msec. But, there is probably no benefit to separating them more than 5 msec. The same parameters that provide independent control of brightness also produce spatial patterns that the subjects' report as being similar to the sum of individual electrode phosphenes. Simultaneous stimulation of multiple electrodes can sometimes produce physical sensation or discomfort in the eye. Time-shifting the pulses cab also be used to reduce the physical sensations felt by the patient. | 2009-12-17 |

20090312820 | ENHANCED SIGNAL PROCESSING FOR COCHLEAR IMPLANTS - The restoration of melody perception is a key remaining challenge in cochlear implants. A novel sound coding strategy is proposed that converts an input audio signal into time-varying electrically stimulating pulse trains. A sound is first split into several frequency sub-bands with a fixed filter bank or a dynamic filter bank tracking harmonics in sounds. Each sub-band signal is coherently downward shifted to a low-frequency base band. These resulting coherent envelope signals have Hermitian symmetric frequency spectrums and are thus real-valued. A peak detector or high-rate sampler of half-wave rectified coherent envelope signals in each sub-band further converts the coherent envelopes into rate-varying, interleaved pulse trains. Acoustic simulations of cochlear implants using this new technique with normal hearing listeners, showed significant improvement in melody recognition over the most common conventional stimulation approach used in cochlear implants. | 2009-12-17 |
