An instructional device for an instructor to use with a student for downhill skiing is disclosed. In use, the instructor skis to the side and behind the student skier. A curved extension member is provided at the end of a shaft and is placed against the student skier's midsection to provide stability and balance for the student. Two student handles can be attached to the extension member. The student handles serve two purposes. The device can be easily converted for use either from the student's right side or left side, depending on the instructor's preference. Second, the student handles can be added as the student progresses to help correctly position the student's hands and develop good posture for the eventual use of ski poles. An instructor handle is located along the shaft. The instructor handle may be adjustable along the length of the shaft.

An Internet of Thing (IoT) sport device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

A helmet for protecting a wearer's head. The helmet includes an outer shell including a first shell member and a second shell member movable relative to one another in a longitudinal direction of the helmet to adjust a fit of the helmet on the wearer's head. The helmet includes an adjustment mechanism configured to control movement of the first shell member and the second shell member relative to one another. The adjustment mechanism includes an actuator movable between a first position in which the first shell member and the second shell member are allowed to move relative to one another and a second position in which the first shell member and the second shell member are precluded from moving relative to one another. The actuator is configured to lock the first shell member and the second shell member relative to one another without extending through a given one of the first shell member and the second shell member.

A system for analysis of user gait and foot disorder intended to minimize risks ulceration and limb amputation associated with the uncontrolled increase of the foot temperature in persons with diabetes. This system comprises a motion, force and temperature sensors and a processing element configured to process motion algorithms, measure ground reaction force (GRF) and changes in foot temperature embedded in the footwear insoles in communication with a smartphone based analysis application using wireless radio interface. The analysis application processes data received from the footwear sensors, compares the results with set of criteria and rules, and if any of the predefined criteria is exceeded, provides alerts to the user and the remote medical supervisor. Additionally, the insoles may be equipped with a haptic actuators configured to determine the level of the user neuropathy by measuring vibration perception threshold (VPT) level.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

A ski exercising apparatus has a set of two parallel, arcuate rails, a wheeled carriage riding on the rails, a set of two articulated footpads mounted side-by-side on the wheeled carriage; and two sets of powerbands arranged parallel with a lengthwise centerline of the apparatus, spaced apart by at least one-half of the width of the apparatus.
