Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a modular defibrillator architecture is described. A base unit provides a fully functional defibrillator. The functionality of the base unit can be supplemented by attaching an interface unit to the base unit or by connecting a smartphone the base unit. Such devices provide connectivity as well as a screen for displaying supplementary graphics and/or videos which are useful to support both emergency and maintenance & monitoring activities. In some embodiments a battery pack may also or alternatively be coupled to the base unit to prolong the unit's shelf life before recharging or replacement of its batteries is required. If necessary the base unit can be powered from a connected external device such as a mobile communication device.

An interposer assembly having a housing with contact positioning holes each having a first wall face and a second wall face. The interposer contact has a base portion with shoulder portions and contact arm portions. The base portion is closer to the first wall face. The contact arm portions are once bulged from both respective vertical ends of the base portion toward the first wall face and then curved toward the second wall face. The housing has a retaining protrusion and a pair of slit portions. The retaining protrusion retains the interposer contact inside the contact positioning hole. Each of the shoulder portions is inserted into the slit portion. The slit portion blocks the interposer contact from moving toward the second wall face.

A base plate of an ostomy appliance includes a first adhesive layer and a masking element. The first adhesive layer includes a stomal opening with a center point and a proximal surface configured to be attached to a skin surface of a user. The masking element is arranged on a distal surface of the first adhesive layer and is more insulative than the first adhesive layer. A plurality of electrodes is arranged on the distal surface of the first adhesive layer, where each electrode includes a sensing part and a conductor part. The masking element is arranged between the conductor part of each electrode and the first adhesive layer. The electrodes are formed on a proximal surface of a support layer.

An electrical contact for connecting a chip module to a print circuit board, the electrical contact comprises a main body, an upper elastic arm and a lower mounting arm extending upwardly from the main body, and a lower elastic arm and a lower mounting arm extending downwardly from the main body. The upper mounting arm is disposed at the downside of the upper elastic arm and forms a space therebetween; the lower mounting arm is disposed at the downside of the lower elastic arm and forms a space therebetween. The upper elastic arm and the lower elastic arm are respectively deformed by the chip module and print circuit board to resist to the upper mounting arm and lower mounting arm, thereby shortening the current path between the chip module and the print circuit board for improving the high frequency performance of an electrical connector.

Embodiments disclosed herein relate to a base plate and/or a sensor assembly part of an ostomy appliance. In embodiments, the base plate and/or the sensor assembly part comprises a first adhesive layer, a masking element, and a plurality of electrodes. The first adhesive layer includes a stomal opening with a center point and a proximal surface configured to be attached to a skin surface of a user. The masking element is arranged on a distal surface of the first adhesive layer, and is more insulative than the first adhesive layer. Further, the plurality of electrodes are arranged on a distal side of the first adhesive layer. Each electrode includes a sensing part and a conductor part and the masking element is arranged between the conductor parts and the first adhesive layer.
