A charging system can include provisions for providing power to various systems or components associated with the article of footwear. A charging system may include a charging device dimensioned to be used with one or more articles of footwear, where the articles of footwear can include different sizes. In some cases, the charging system can be used to facilitate the transfer of power to components in a motorized tensioning system.

An article of footwear or an article of apparel can include provisions for facilitating the installation of a control device. The control device can include a panel comprising a plurality of buttons that can provide manual control to a user. The control device can be installed in a compartment within the article after initial manufacture of the article of footwear. In some cases, the control device can include a raised standoff assembly that can be configured to decrease inadvertent pressure being applied to the buttons.

An article of footwear with an automatic lacing system is disclosed. The automatic lacing system provides a set of straps that can be automatically opened and closed to switch between a loosened and tightened position of the upper. The article further includes an automatic ankle cinching system that is configured to automatically adjust an ankle portion of the upper.

Systems and apparatus related to footwear including a modular lacing engine are discussed. In this example, the lace guide is deformable to assist in facilitating automated lace tightening. The lace guide can include a middle section, a first extension and a second extension. In this example, the lace guide can be configured to define a first route for a lace cable, the first route including receiving the lace cable along the first incoming lace axis and expelling the lace cable along the first outgoing lace axis. In this example, the lace guide can also deflect, in response to tension on the lace cable, resulting in defining a second route for the lace cable, the second route including receiving the lace cable along a second incoming lace axis and expelling the lace cable along a second outgoing lace axis.

A system, recharge apparatus, and method includes transmit coils positioned in a pattern to allow at least one of the transmit coils to establish a wireless link with a receive coil positioned in proximity of the recharge apparatus. A power source is coupled to the transmit coils and configured to selectively energize ones of the transmit coils to transfer power to the receive coil. An energy efficiency detection circuit is configured to detect an electrical response of each one of the transmit coils when energized by the power source, the electrical response indicative of an energy efficiency between the one of the transmit coils and the receive coil. The power source selectively energizes ones of the transmit coils, selected according to a statistical analysis of an historical record and the electrical response indicative of the energy efficiency meeting a minimum efficiency criterion for energy transfer to the receive coil.

A method and system for activity classification. A pressure sensor receives input data resulting from physical activity of a subject performing an activity. The input data includes pressure data from at least one pressure sensor, and may include other data acquired through other types of sensors. A deep learning neural network is applied to the input data for identifying the activity. The neural network is trained with reference to training data from a training database. The training data may include empirical data from a database of previous data of corresponding activities, synthesized data prepared from the empirical data or simulated data. The training data may include data from physical activity of the subject being monitored by the system. Different aspects of the neural network may be trained with reference to the training data, and some aspects may be locked or opened depending on the application and the circumstances.

The present invention relates to a shoe including a sole as well as an upper that rises up from the sole, the upper including at least two portions that are at least partially mutually displaceable with respect to each other, thereby adjusting the housing size or volume (RZ) for a foot in the shoe, as well as tightening-release means of the mutually displaceable portions, the shoe also including control means of the tightening-release means operable or arranged at the back or at the heel of the shoe.

An article includes a cord, a cord winding device that tightens and loosens the cord, a drum including a winding portion around which the cord is wound, a drum retainer that accommodates the drum in a rotatable manner, and two cord exits formed in a wall of the drum retainer to guide the cord out of the cord winding device. When the two cord exits and a center of the drum retainer are not located on a single straight line, even if the cord is rewound by a full extent and drawn out from one of the cord exits when the cord is loosened, fatigue that would be caused by kinks reversing a winding direction of the cord or repetitive bending of the cord does not occur at a connecting-fixing portion of the cord and the winding portion corresponding to the other one of the cord exits.

An article of footwear may comprise an upper and a closure system. The closure system may include a strap, a tensioning cable, and a plurality of pulleys. The strap may have a fixed end fixed relative to the upper, a free end selectively securable to the upper in a fastened position, and an elastic portion between the fixed end and the free end. The closure system may include a tensioning cable anchored to the upper and secured to the strap. The closure system may also include a plurality of pulleys anchored to the upper and engaging the tensioning cable. The tensioning cable may be configured to tighten against the upper when the elastic portion of the strap stretches as the free end of the strap is pulled.

A pulley for a wearable article includes a frame defining an aperture and a slot spaced apart from the aperture. A pulley wheel is disposed exterior to the frame, and a hub extends from the pulley wheel through the aperture. The hub engages the frame in a locked position, and is disengaged from the frame in an unlocked position. The hub is further from the slot in the locked than in the unlocked position. The hub and the pulley wheel are rotatable relative to the frame in the locked position. In another pulley, a frame defines an internal void and a slot extending through the frame and spaced apart from the internal void. A pulley wheel disposed exterior to the frame is spaced apart from the slot. A plurality of legs extends from the pulley wheel and is locked to the frame. The frame may include an anchor bar.
