Patent number: 11867333Abstract: A fluid coupling has two similar coupling halves, each with a rotary body of a valve. A drive device for closing/opening the valve is associated with each rotary body. Each half has a coupling means for connecting/decoupling the halves by relative rotation. Securing means secure the connection when at least one valve is open and close the two rotary valves to disconnect/connect the halves. The drive device is arranged on one half and has a drive shaft which is associated with a valve shaft of the rotary body of the other half. A locking connection is configured which, when the halves are connected, connects the drive shaft on one half to the valve shaft on the other in a non-rotatable/releasable manner such that the rotation of the rotary body is controllable and relative rotation of the halves is blocked but the relative rotation when the valves are closed is permitted.Type: GrantFiled: June 6, 2018Date of Patent: January 9, 2024Assignee: Stäubli Hamburg GmbHInventors: Hauke Peter Hamkens, Jan-Oliver Sylla, Eugen Schwarz

Patent number: 11229388Abstract: A system and method detect neuronal action potential signals from tissue responding to electrical stimulation signals. A sparse signal space model for a set of tissue response recordings has a signal space separable into a plurality of disjoint component manifolds including a neural action potential (NAP) component manifold corresponding to tissue response to electrical stimulation signals. A response measurement module is configured to: i. map a tissue response measurement signal into the sparse signal model space to obtain a corresponding sparse signal representation, ii. project the sparse signal representation onto the NAP component manifold to obtain a sparse NAP component representation, iii. when the sparse NAP component representation is greater than a minimum threshold value, report and recover a detected NAP signal in the tissue response measurement signal.Type: GrantFiled: June 17, 2019Date of Patent: January 25, 2022Assignee: MED-EL Elektromedizinische Geraete GmbHInventors: Stefan Strahl, Konrad Eugen Schwarz, Philipp Spitzer

Patent number: 10863911Abstract: A hearing implant fitting system includes a physiological database containing physiological data characterizing auditory neural tissue response to electrical stimulation. A neural action potential (NAP) measurement system measures NAP signals from cochlear tissue responding to electrical stimulation signals delivered by one or more of the electrode contacts, including: deriving a compound discharge latency distribution (CDLD) of the cochlear tissue by deconvolving: (1) a tissue response measurement signal taken responsive to the delivered electrical stimulation signals, with (2) an elementary unit response signal representing voltage change at a measurement electrode contact due to the electrical stimulation, and then comparing the CDLD to physiological data from the physiological database to detect an NAP signal from the tissue response measurement signal.Type: GrantFiled: February 9, 2018Date of Patent: December 15, 2020Assignee: MED-EL Elektromedizinische Geraete GmbHInventors: Stefan Strahl, Konrad Eugen Schwarz, Angelika Dierker, Philipp Spitzer
