A sensor apparatus for footwear includes at least one pair of light sources and at least one pair of light receivers, each light receiver being positioned and configured to receive light emitted from a respective one of the light sources. A pair of movable curtains functions to adjust the amount of light received by the pair of light receivers. The curtains are movable conjointly such that the amount of light received by one of the light receivers is inversely proportional to the amount of light received by the other light receiver. (FIG. 1B).

A footwear system includes a sensorized insole and a charger. The sensorized insole has an insole bulk having a foot-facing upper surface. A sensor is embedded in the insole bulk for measuring a parameter of a user's foot, a battery is embedded in the insole bulk for providing energy to the sensor, and a receiver pod is embedded in the insole bulk and is spaced from the foot-facing upper surface for wirelessly receiving energy and providing energy to the battery. The charger provides energy to the receiver pod, and includes a cable for connecting to an energy source, and a transmitter pod electrically connected to the cable for receiving energy from the cable and wirelessly transmitting energy to the receiver pod. The transmitter pod is positionable against the foot-facing upper surface to wirelessly provide energy to the receiver pod through the insole bulk.

A monitoring system a user activity sensor to determine patterns of activity based upon the user activity occurring over time.

An apparatus includes a frame, a sensor, and an electric stimulator. The frame is removably couplable to a portion of a limb. The sensor is configured to produce a first signal associated with a gait characteristic at a first time, and a second signal associated with the gait characteristic at a second time, after the first time. The electric stimulator is removably coupled to the frame and is in electrical communication with an electrode assembly and the sensor to receive the first signal substantially at the first time and the second signal substantially at the second time. Based in part on the gait characteristic at the first time, the electric stimulator sends a third signal to the electrode assembly to provide an electric stimulation to a portion of a neuromuscular system of the limb substantially during a time period defined between the first time and the second time.

Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

A system includes a wearable article and a housing assembly including a receptacle defining a chamber and having an access opening providing access to the chamber to removably receive an electronic module within the chamber. The housing assembly further includes an interface having first and second electrical contacts exposed to the chamber. First and second conductive leads are connected to the electrical contacts through the bottom side of the receptacle to place the leads in electronic communication with the contacts. The housing assembly is bonded between top and bottom layers of material forming a portion of the wearable article, such that the layers are bonded to the receptacle by a bonding material.

A mount for a device configured to monitor the movements or other activities of patient. Aspects include a monitoring unit and base, where the base may further include a pad with one or more pins extending into the base. The pad may be positioned inside a garment worn by a patient, the pins passing through the garment and electrically connecting to circuits in the fabric of the garment (e.g. a sock worn by the patient). The circuits may include sensors which are response to changes in pressure caused by patient movement. Output from the sensors may be carried by the circuits in the garment to the pins in the pad, and from there through the garment and into the base and the monitoring unit for processing and reporting to caregivers as needed.

Disclosed embodiments include a multi-mode sensor including an elastomeric strand having a first multi-mode sensing region configured to sense at least two different physical parameters, and a second multi-mode sensing region, space apart from the first multi-mode sensing region, and configured to sense at least two different physical parameters. In some disclosed embodiments the first multi-mode sensing region is configured to measure the physical parameters of angular displacement and strain.

A method of providing workout training for a user of an activity tracking system includes displaying a plurality of training plan options to the user on a screen of a personal electronic device, and then receiving a selected training plan option from the user. Selected workout day options are received from the user and the system generates a training schedule for the user based on the selected training plan and the selected workout day options. One or more reminders identify the type of workout for the scheduled day and an option to accept or reject the workout. When the user selects the option to accept the workout, the workout goal associated with the scheduled workout is displayed. The method further includes determining progress toward the workout goal based on the received workout data, and displaying an indicator of progress toward the workout goal on the screen during the workout.
