Title: Laser welding quality evaluation method and apparatus therefor
Inventor: NISHIO MASAHIRO
IPC: B23K26/21
Filed: 2008-08-06
Abstract: A difference processing circuit (22) receives an input of a welding time image captured by a CCD camera (8) in real time, subtracting the power monitoring time image stored in a memory (21) from the welding time image, and thereby acquires a difference processing reflected light image. By this difference processing, foreign matter images included in the welding time image and the power monitoring time image are canceled, and the difference processing reflected light image does not include any foreign matter image. A quality judging device (17) judges the welding quality by using the difference processing reflected light image. As stated above, since the difference processing reflected light image does not include any foreign matter image, the quality judging device (17) can perform good evaluation of the welding quality without being influenced by any foreign matter adhering to a protective glass (15).

Abstract: Embodiments provide systems and methods for determining the geolocation of an emitter on earth. A solution is obtained from two TDOA measurements that need not be acquired at the same time. A solution is obtained from a TDOA measurement and an FDOA measurement that need not be acquired at the same time and need not be coming from the same satellite pair. A location of an emitter can be determined from minimizing a cost function of the weighted combination of the six solutions derived from the two TDOA measurements and the two FDOA measurements, where the weight of each solution in the combination is determined based on the intersection angle of the two curves that define the possible locations of the emitter based on the TDOA and/or FDOA measurements.

Abstract: The present invention concerns compositions, methods and/or apparatus of central administration of various CNS-active agents. In particular embodiments, intrathecal administration is advantageous for decreasing the systemic concentrations of CNS  agent, thereby decreasing side effect toxicity, while allowing more effective delivery of the agent to the site of action, simultaneously decreasing the dosage delivered to the subject. In particular embodiments, ICV  delivery may be of use for patients who have previously proven to be refractory to systemic administration of CNS agents, in some cases due to systemic side effects, or for those patients whose symptoms are of sufficient severity to warrant more aggressive therapeutic intervention. ICV administration allows not only lower systemic concentration but also higher therapeutically effective concentration within the CNS.
