Abstract: 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.

Abstract: 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.

Abstract: 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.
