Abstract: The disclosure provides methods and systems for determining an emotional fitness metrics for users. A physiological parameter of the user is measured during a group activity using at least one biosensor to acquire a measured signal. The measured signal of the user is compared to a measured signal for the physiological parameter of one or more additional users as measured when the one or more additional users perform the group activity. An emotional connectivity may be calculated based on a synchronicity of the measured signal of the user with the measured signal of the one or more additional users, as well as a cognitive appraisal metric, a resilience metric and an emotional fitness metric. Connectivity values for user pairings for a group activity can be computed based a synchronicity in a time-series correlation for the physiological parameters for permutations of the user pairings for the group activity.

Abstract: A reconfigurable vacuum attachment may include a bell-shaped housing. The bell-shaped housing may have a bell-opening and a hose-interface. The hose-interface may be configured to hydraulically couple with a vacuum hose. A skimmer-plate may be attachable to the bell-opening and include a skimmer-aperture extending through the skimmer-plate. The reconfigurable vacuum attachment may further include a removable brush assembly. The brush assembly may host a rotatable brush coupled to a brush driver. The brush driver may be configured to hydraulically couple with the vacuum hose and convert water flow into a torque and spin the bristles. A buoy may be attached to the housing allowing the reconfigurable vacuum attachment to be used as a pool skimmer. The reconfigurable vacuum attachment is useful for skimming a pool surface and dislodging and vacuuming matter from a pool wall.
