Patent number: 9295526Abstract: A cochlear implant device includes a deformable and stretchable flexible strip composed of a biological compatible material and positioned about a longitudinal axis so as to form a spiral. The implant device has a plurality of conductive strips with electrode windows formed so as to expose a segment of each conductive strip. A density of the electrode windows is sufficient to monitor a distance of the flexible strip from a non-conductive tissue of a patient in a 360 degree field of view about the longitudinal axis. A method of inserting a cochlear implant includes providing a multi-joint robot comprised of a series of actuator units, guiding the multi-joint robot into an inner ear of a patient, monitoring the position of the multi-joint robot relative to a non-conductive portion of the patient; and applying current to the multi joint robot so as to adjust the position of the actuator units.Type: GrantFiled: November 8, 2013Date of Patent: March 29, 2016Assignee: New York UniversityInventors: Rodolfo R.

Patent number: 8659818Abstract: An optical-path-switching apparatus according to the present invention includes a reducing optical system capable of guiding signal light and control light along the direction of gravity into a thermal-lens-forming optical element having an incidence plane positioned to be perpendicular to the direction of gravity in such a way as to differentiate respective convergence points in a direction perpendicular to the optical axis. The apparatus further includes a light-receiving unit configured to converge or condense straight-traveling signal light in the absence of irradiation with the control light and signal light whose optical path has been switched due to irradiation with the control light using the same optical element. Further, the apparatus includes a wedge-type prism provided at a passing position of the optical-path-switched signal light to increase the distance between the optical axis of the optical-path-changed signal light and the optical axis of the straight-traveling signal light.Type: GrantFiled: March 29, 2011Date of Patent: February 25, 2014Assignees: National Institute of Advanced Industrial Science and Technology, Inter Energy Co., Ltd., Dainichiseika Color & ChemicalInventors: Ichiro Ueno, Takashi Hiraga, Noritaka Yamamoto, Hirobumi Watanabe, Shiro Futaki, Noriyasu Shiga, Norio Tanaka, Shigeru Takarada
