A sport-boot pressure monitoring system and method of use. The system includes a left boot sensor having a left flexible fluid-containing bladder shaped to fit between a user's left leg and an interior surface of a left boot worn by the user and a left pressure sense element in pressure-sensing communication with the left flexible fluid-containing bladder, a right boot sensor that is similar to the left one, and a controller to provide a pressure alert if pressure between one of the user's legs and the interior surface of the boot worn on that leg violates a predetermined pressure threshold and to provide a proximity alert if a distance between the left and right boots violates a predetermined proximity threshold.

A rehabilitation footwear device for assisting in controlling weight application to an injured lower appendage includes a shoe that is configured to position around and reversibly couple to a foot of a user. A control module that comprises a power module and a microprocessor is coupled to the shoe. The microprocessor is operationally coupled to the power module. A plurality of sensors is coupled to and positioned in a sole of the shoe. The sensors are operationally coupled to the microprocessor. The sensors are configured to measure pressure applied to the sole from the foot that is positioned in the shoe and to relay a pressure measurement to the microprocessor. A speaker is coupled to the shoe. The speaker is operationally coupled to the microprocessor. The microprocessor is positioned to compel the speaker to emit an audio alert should the pressure measurement exceed a threshold limit.

A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

Apparel is disclosed that can be worn to assist an interactive game in tracking the movement of the wearer. The apparel may include one or more tracking marks formed of designs, patterns, or reflective materials that can be easily tracked by an interactive game. By providing tracking marks on apparel, rather than using a special-purpose device that must be separately worn, a player may enjoy a more natural feel when playing the interactive game. A user can wear the apparel for everyday purposes, and then simply begin playing the game wearing the apparel without having to put on any additional equipment. The apparel may use reflective materials, and the interactive game can employ a camera and a light source configuration where the camera is located within the observation angle of a player employing retroreflective materials reflecting light from the light source.

A toddler shoe has a squeaker or other air-powered noisemaker (collectively squeaker) that is selectively active in that the squeaker can be turned on or off. The squeaker can be turned on or off without removing the squeaker from the shoe, and because the squeaker remains in the shoe, the functional characteristics of the shoe are unaffected by the on or off state of the squeaker.

Adaptive output control is performed on the basis of sound and motion.

Footwear includes a sensor portion that detects motion of the footwear, a transmission portion that transmits sensor data detected by the sensor portion to an external apparatus, a reception portion that receives an output control signal based on sound data and the sensor data from the external apparatus, and an output portion that performs output based on the output control signal.

An article of footwear includes an upper member and a sole structure, with a sensor system connected to the sole structure. The sensor system includes a plurality of sensors that are configured for detecting forces exerted by a user's foot on the sensor. The sensor system also includes a port that is configured to receive a module to place the module in communication with the sensors. The port includes a housing with a chamber configured to receive the module and an interface engaged with the housing and having at least one electrical contact exposed to the chamber. Additional retaining structure and interface structure may be included.

A footwear system that includes a left having a left toe region, left forefoot region, a left arch region and a left heel region, a left outsole, a left upper secured to the left outsole, and a left sensor system that includes at least a first left heel pressure sensor positioned in the left heel region, and at least a first left forefoot pressure sensor positioned in the left forefoot region. The footwear system also includes a right shoe that includes a right toe region, a right forefoot region, a right arch region and a right heel region, a right outsole, a right upper secured to the right outsole, and a right sensor system that includes at least a first right heel pressure sensor positioned in the right heel region, and at least a first right forefoot pressure sensor positioned in the right forefoot region.

A footwear arrangement including a wireless interface device capable of sending input signals and receiving output signals to a first shoe having a primary controller. The primary controller sends signals to the second shoe, which has a slave controller that is controller that is controlled by signals from the primary controller.

In one embodiment, a shoe includes a top portion configured to provide covering to a top of a user's foot, a sole portion coupled to the top portion, and one or more processors embedded within the sole portion. Communicatively coupled to the one or more processors are one or more memory modules, one or more user input devices, and a user output device. The user input device includes at least a microphone. Machine readable instructions stored in the one or more memory modules, when executed by the one or more processors, cause the shoe to: receive a command from a user with the one or more user input devices; process the command from the user; and output information with the user output device relevant to the command from the user.
