Example embodiments relate to receptacle assemblies with gaskets. One example includes a receptacle assembly for a luminaire system. The receptacle assembly includes a receptacle and a gasket. The receptacle has a front side and a rear side. The front side is configured for receiving electrical contacts of an external module. The rear side is configured for extending in an opening of a housing, preferably a luminaire housing, and for being electrically connected to components in the housing. The gasket is configured for being located between the receptacle and the housing on which the receptacle is to be mounted. The receptacle assembly is provided with an indicator means at a location which is visible when the receptacle is mounted on the housing.

A coupling arrangement for a bio-signal measurement, comprises at least two spring connectors of a bio-signal processing device, and a holder comprising a combination of a wall and a substrate, which form a pocket inside the holder, the wall following an outer contour of the bio-signal processing device. The holder has an aperture for inserting the bio-signal processing device into the pocket and removing the bio-signal processing device from the pocket. The holder includes electric conductor lines, which are in a wired electric contact with electrodes of the substrate, the electrodes receiving at least one bio-signal. The electric conductor lines are attached on the substrate inside the pocket, the electric conductor lines and the at least two spring connectors connecting electrically with each other in response to insertion of the bio-signal processing device in the pocket.

An electrically operated aerosol-generating system is provided, including an aerosol-generating device having a first connector part; a charging unit to receive the device and having a second connector part. The first part includes first through third electrical contacts, the third at least partially circumscribes the first. The second part includes first through third electrical contacts, the second and the third being spaced radially outwardly from the first. The first and the second parts electrically engage when the device is received by the charging unit, such that the first contact of the first and the second parts engage, the second contract of the first part engages the second or the third contact of the second part, and the third contact of the first part engages the other of the second or the third contact of the second part, regardless of angular position of the second part relative to the first.

A combination outlet connector is disclosed. The combination outlet connector includes an outlet core having three T-shaped apertures. The outlet core has a core outer surface to mate with a first connector type, such as a C14 connector, and electrical terminals are positioned in corresponding apertures. A removable adapter sleeve is positionable around the outlet core and has a sleeve outer surface to mate with a second connector type, such as a C20 connector. The adapter sleeve includes a sleeve aperture at least partially congruent with the core outer surface. The electrical terminals are configured to connect with mating terminals of the first and second connector types. A removable adapter shroud can be positioned around the outlet core. The shroud includes a shroud inner surface to receive the first connector type and a shroud flange having a shroud aperture at least partially congruent with the core outer surface.

A bio-signal measurement apparatus comprises tool-less connectors, coupling targets, a controllable coupling selection arrangement, and a control arrangement. The tool-less connectors are for an electric contact with a separate docking apparatus or an electrode arrangement. The coupling targets include a battery and a data communication unit that performs electrically a plug-and-play data transfer with the separate docking apparatus. The tool-less connectors, the number of which is three, are electrically coupled with the controllable coupling selection arrangement, which electrically couples all the tool-less connectors with only one of the coupling targets at a time in response to control from the control arrangement. The battery receives electricity from the tool-less connectors for charging the battery through the electric coupling caused by the coupling selection arrangement under control of the control arrangement during a first time window when the bio-signal measurement apparatus is connected with the docking apparatus. The data communication unit sends and/or receives data through the tool-less connectors using the plug-and-play data transfer based on the electric coupling caused by the coupling selection arrangement under control of the control arrangement during a second time window when the bio-signal measurement apparatus is connected with the docking apparatus.
