Patent number: 9377368Abstract: The present application discloses instruments, systems, and methods for measuring temperature. In one example, an instrument or heat sensor probe includes a housing that defines a chamber, which is configured for a fluid to circulate therein, and a body of material disposed over the housing. The body has a first side proximal to the housing and a second side distal from the housing. The probe further includes a heat sensor configured for sensing heat at a position spaced inwardly from the second side of the body.Type: GrantFiled: March 15, 2013Date of Patent: June 28, 2016Assignee: Cochlear LimitedInventors: Martin Kieliszek, Dirk Fiedler

Publication number: 20070259255Abstract: A secondary electrochemical cell with at least one positive electrode includes an active material and one negative electrode, which are held directly in a hermetically tight housing which has at least one detector element or which is dynamically connected to one such detector element. The detector element is designed or can be set to acquire a predetermined unallowable operating state of the secondary electrochemical cell, and in an unallowable operating state of the secondary electrochemical cell, to actuate at least one switching element which prevents recharging and/or discharging of the secondary electrochemical cell. By making the housing as a hermetically tight protective housing, which is part of an implantable medical device, contamination of surrounding tissue with toxic substances and hazard to the implant wearer by the malfunction of the secondary electrochemical cell can be precluded under all operating conditions with simultaneously great reduction of all dimensions.Type: ApplicationFiled: April 9, 2007Publication date: November 8, 2007Applicant: Cochlear LimitedInventors: Hans Leysieffer, Dirk Fiedler, Dieter Muller

Publication number: 20060147775Abstract: A zinc air-type battery comprising first and second cathodes each with positive contacts and an anode with a negative contact. The second cathode is situated proximal to the negative contact and proximal to the anode, which can enable air ingress to be substantially doubled and the internal resistance of the battery to be substantially halved, and further can provide for a relatively short diffusion length of ions from the second cathode.Type: ApplicationFiled: September 5, 2003Publication date: July 6, 2006Inventor: Dirk Fiedler

Patent number: 6192272Abstract: An implant comprising an electric power consuming device electrically coupled to an electric power source including an anode, a cathode and at least one potential probe which is independent of the anode and the cathode. By providing at least one potential probe which is independent of the anode and the cathode, implants can be monitored and controlled to avoid process which can damage the electrodes and shorten the service life of the electrodes and the service life of the implant itself.Type: GrantFiled: May 14, 1999Date of Patent: February 20, 2001Assignee: Implex Aktiengesellschaft Hearing TechnologyInventor: Dirk Fiedler
