A case-neutral electrochemical cell has an electrode assembly comprising a separator positioned between an anode and a cathode housed inside a casing. The casing supports a co-axial glass-to-metal seal comprising an inner insulating glass hermetically sealed to a terminal pin and to the inner annular surface of an inner ferrule. An outer insulating glass is hermetically sealed to the outer annular surface of the inner ferrule and the inner annular surface of an outer ferrule, and the outer ferrule is secured to an opening in the casing. Then, one of the anode and the cathode is connected to the terminal pin and the other of the anode and the cathode is connected to the first or inner ferrule. An electrolyte is provided in the casing to activate the electrode assembly.

Co-axial glass-to-metal seal for a case-neutral electrochemical cell

A case-neutral electrochemical cell has an electrode assembly comprising a separator positioned between an anode and a cathode housed inside a casing. The casing supports a co-axial glass-to-metal seal (GTMS) comprising an inner insulating glass hermetically sealed to a terminal pin and to the inner annular surface of an inner ferrule. An outer insulating glass is hermetically sealed to the outer annular surface of the inner ferrule and the inner annular surface of an outer ferrule. The outer ferrule is secured to an opening in the casing. Two methods are described for manufacturing a co-axial GTMS depending on the melting temperatures of the inner and outer insulating glasses. Then, one of the anode and the cathode is connected to the terminal pin and the other of the anode and the cathode is connected to the inner ferrule. An electrolyte is provided in the casing to activate the electrode assembly.

Co-axial glass-to-metal seal feedthrough for a case-neutral electrochemical cell

A feedthrough filter capacitor assembly comprising a terminal pin connector is described. The terminal pin connector is designed to facilitate an electrical connection between the terminal pin comprising a multitude of compositions to a circuit board of an implantable medical device. The terminal pin connector comprises a clip portion positioned within a connector housing. The connector clip mechanically attaches to the terminal pin of the feedthrough with at least one prong and an exterior surface of the connector housing electrically contacts the circuit board, creating an electrical connection therebetween. The connector housing comprises a material that is conducive to a weld or solder attachment process to the circuit board. The feedthrough filter capacitor assembly is particularly useful for incorporation into implantable medical devices such as cardiac pacemakers, cardioverter defibrillators, and the like, to decouple and shield internal electronic components of the medical device from undesirable electromagnetic interference (EMI) signals.

A surgical tool handle for holding, securing and portioning orthopedic tools is described. The surgical tool handle having a tool attachment mechanism comprising a bias member connected to an actuator. The bias member is positioned within a distal end opening within the handle. Rotation of the actuator causes rotation of the bias member such that when a connection member of a tool, such as a broach, rasp or other cutting tool, is positioned within an opening of the bias member, the bias member wraps around and tightens onto the connection member. Rotating the actuation cable in an opposite direction rotates the bias member in the opposite direction, which thereby releases the tool connection member, and the tool, from the handle.

Various embodiments of modular battery authentication circuits are described. The various modular battery authentication circuits are intended to be utilized with electrically powered devices that do not comprise existing battery authentication capabilities. In one embodiment, a modular battery authentication adapter is described. The adapter comprises a housing in which a modular battery authentication circuit resides. One end of the adapter is positioned within a power input port of a device and a modular battery is positioned within the opposing end of the adapter. The authentication circuit within the adapter communicates with the modular battery to determine its authenticity before allowing the battery to power the device. A modular battery comprising an internal authentication circuit is also described. The modular battery is designed to interact with firmware stored within the device to determine whether the modular battery meets certain operational criteria.

Battery authentication circuit

The present invention is directed to ambient temperature molten salts as non-aqueous electrolytes. The molten salts comprise a cation of a guanidine moiety and an anion. The guanidine cation is asymmetrically halogenated, which means that in the general formula: C(NR), one or two, but not all three, of the N atoms are bonded to R radicals that are the same for each thusly substituted N atom and the third N atom is bonded to hydrogen or two of the same R radicals, and if R radicals, they are different than the R radicals bonded to the first and second N atoms. The R radicals bonded to any one N atom is an alkyl group of from 1 to 4 carbon atoms. Either both of the hydrogen atoms or at least one of the hydrogen atoms on each of the R radicals bonded to one or two, but not three, of the N atoms are substituted with the same halogen selected from the group consisting of fluorine, chlorine, bromine, and iodine. Preferably the anion is partially or fully halogenated, and the halogen of the guanidinium cation and that of the anion are the same. The electrolyte is useful with electrochemical devices such as primary and secondary electrochemical cells and capacitors, such as of the electrolytic and electrolytic/electrochemical hybrid types.
