An exemplary wearable mobile device attachment article comprises a mobile device cover with a first face and a second face opposite the first face. An exemplary first face may be configured to provide access to the screen of a mobile device. A receptacle may project outwardly from the second face while a wearable article has at least one surface for frictionally engaging the mobile device cover.

A patch housing for receiving an electronic device is provided. The patch housing includes a flat substrate having a first surface and a second surface with adhesive on at least one of the first or second surfaces. The substrate further includes an opening. The patch housing further includes a set of electrodes included in the substrate. The patch housing further includes a set of connectors provided on the first surface of the substrate. Each connector in the set of connectors is configured to mechanically couple the electronic device to the substrate.

An electronic device includes a housing forming an enclosed chamber. The housing has a top portion and a bottom portion. One or more sensors is provided within the chamber and configured to interface with a user to generate physiological data associated with the user. A set of electrodes is provided on the bottom portion of the housing. Each electrode in the set of electrodes is a single member having a corresponding inner electrode portion within the chamber and an outer electrode portion outside the housing. A set of magnets is provided on the bottom portion of the housing.

An electronic device wearable on a wrist of a user is provided. The electronic device includes a housing forming an enclosed chamber. The housing has a top portion and a bottom portion. The electronic device further includes one or more sensors, a set of electrocardiogram electrodes, and a set of bioimpedance electrodes separate from the set of electrocardiogram electrodes. The one or more sensors are configured to interface with the user to generate physiological data associated with the user. The set of electrocardiogram electrodes are provided on the bottom portion of the housing for generating electrocardiogram data associated with the user. The set of bioimpedance electrodes are provided on the bottom portion of the housing. In some implementations, the electronic device includes a side touch track on a lateral portion of the housing that cooperates with the electrocardiogram electrodes to generate the electrocardiogram data.

A latching mechanism for connecting a first object to a second object is provided. The latching mechanism includes a groove provided along a surface of the first object. The groove includes a notch. The notch can be centered in the groove. The groove is configured to receive a connective end of the second object, and the notch is configured to lock the connective end of the second object in place. The notch can receive a tab from the connective end of the second object.

A timepiece or piece of jewelry includes a structure with a set of horns carrying a bar receiving a removable snap-hook fixed to a strand. The bar includes, at a distance from each of the points of attachment to the set of horns, a notch including two sides which limit the lateral travel of a curved beak portion of the snap-hook and limit the angular travel of the snap-hook with respect to the bar, so as to prevent any contact between the snap-hook and the set of horns to which the bar is fixed.

An accessory having a first face and a second face connected by a lateral face, the second face having a slot extending to the lateral face, forming on the lateral face a hole the shape defined by the transverse cross-section of the slot. The transverse cross-section has an open contour having a bottom and an opening connected by a first lateral side and a second lateral side, the first lateral side and the second lateral side each having a part approaching from the bottom towards the opening, towards the opposite lateral side. The dimension of the bottom of the contour are constant along a direction defined by a direction extending substantially perpendicular to the transverse cross-section and going from the hole towards an inner part of the accessory. The slot is intended to receive a fastener.
