A light-up speed sensing shoe apparatus for tracking speed and motivating runners includes a shoe body, an outsole coupled to the shoe body, and an insole coupled to the outsole within the shoe body. An impact sensor is coupled within the outsole. The impact sensor detects a speed at which a wearer is running. A microprocessor is coupled within the outsole. The microprocessor is in operational communication with the impact sensor. A battery is coupled within the outsole and is in operational communication with the microprocessor. A plurality of lights is coupled to the outsole and is in operational communication with the microprocessor.

Articles of footwear, systems, and methods include an upper portion, a lower portion, secured to the upper portion, the lower portion including an out-sole and an airbag assembly. The airbag assembly includes a first sheet and a second sheet forming a seal therebetween around a perimeter of the first and second sheets. The airbag assembly further includes an electronic assembly, comprising a circuit board and electrical conductors disposed on the circuit board, wherein an internal portion of the electronic assembly is disposed between the first and second sheets and within the seal formed therebetween and an external portion of the electronic assembly is disposed outside of the seal.

A gesture recognition device configured to detect a gesture performed by a user to actuate a motor of a closure mechanism of an article of footwear. The gesture recognition device may include a sensor unit with an accelerometer sensor, and an analysis unit in operative communication with the sensor unit. The analysis unit may be configured to execute a gesture confirmation algorithm to confirm or reject possible gesture event data received from the sensor unit as a true gesture event. If the gesture confirmation algorithm confirms the possible gesture event data as a true gesture event, the analysis unit may output a signal to actuate the motor.

A device is described for detachable contacting of a battery cell (4) having a cell receptacle open against a joining direction (2), which cell receptacle is delimited by a contact spring base (1), from which contact tongues (3) protrude against the joining direction (2) for the jacket-side enclosure of the battery cell (4). To propose a device for detachable contacting of a battery cell (4), which enables a reliable electrical connection independently of the relative location of the inserted battery cells and substantially independently of their diameter even in the event of periodic mechanical strains, without making the assembling procedure more difficult, it is proposed that the contact tongues (3) have contact bodies (5) protruding radially into the cell receptacle in the form of a cut ovoid.
