Methods and apparatus are discussed for an electric powered personal transportation vehicle with electric motors powered by one or more batteries. A set of universal battery mounting hole locations and a reserved space for one or more battery housings exist on a board for the personal transportation vehicle. The reserved space on the board for the one or more battery housings that house one or more battery packs is set to not interfere with an operation of the motors or the wheels. A first battery pack containing the one or more batteries differs in at least one of i) a different amp-hour capacity, ii) a different length, width, or height, and iii) a different shape than another battery pack designed to be physically contained in the one or more battery housings and electrically connect with corresponding electrical connections in the one or more battery housings.

A system for control of a mobility device comprising a controller for analyzing data from at least one sensor on the mobility device, wherein the data is used to determine the gait trajectory of a user. The gait data is then used to provide motion command to an electric motor on the mobility device.

A motorized skateboard has a maneuverable rear truck. The riding platform on which the user stands includes a rotatable steering platform that the rider can step on with his rear foot. In the nominal position the steering platform extends slightly above the rest of the riding platform and is locked from rotating. When a user steps on the steering platform, the steering platform gets pushed downward against a spring. The downward movement causes a wedge to force apart two pawl level arms, thus disengaging respective pawls from a ratchet thereby unlocking the steering. In this position the steering platform is rotationally coupled to the rear truck through two spur gears acting in serial such that as the user pivots his foot clockwise, the rear truck turns counterclockwise, and vice versa. The result is a steering motion that is similar to turning a snowboard.

According to an aspect of some embodiments of the present invention there is provided a driving unit for an in-line skate system having roller wheels, the driving unit has a motor configured to generate a driving power, a transmission gear coupled to the motor, and a transmission belt interconnecting the transmission gear and the two or more roller wheels to transfer the driving power to the roller wheel. According to an aspect of some embodiments of the present invention there is provided an in-line skate system, comprising one or more in-line skates and a driving unit.

A ski binding release system includes a spring that is releasably maintained in a first state using a pyrotechnic fastener. In the first state, a ski boot is secured in the ski binding. The pyrotechnic fastener is electrically coupled to an activation circuit. The activation circuit includes a battery, a plurality of sensors, a switch, and a controller. When the controller determines that the skier has fallen, the controller generates an output signal that transitions the switch from a disconnected state to a connected state. In the disconnected state, the pyrotechnic fastener is electrically disconnected from the battery. In the connected state, the pyrotechnic fastener is electrically connected to the battery. Electrical energy from the battery causes the pyrotechnical fastener to explode to transition the spring from the first state to a second state to release the ski boot from the ski binding.

A personal conveyance including a flexible substrate, a wheel and an electric motor mounted to a first wheel assembly, the wheel rotatably supported by the first wheel assembly and the electric motor configured to drive the wheel, wherein the first wheel assembly is mounted to the flexible substrate, a battery mounted to the flexible substrate and configured to power the electric motor, and a processor configured to control operation of the electric motor.

Various implementations include approaches for training a surface detection classifier and detecting characteristics of a surface, along with related micromobility vehicles. Certain implementations include a method including: comparing: i) detected movement of a micromobility (MM) vehicle or a device located with a user at the MM vehicle while operating the MM vehicle, with ii) a surface detection classifier for the MM vehicle; and in response to detecting that the MM vehicle is traveling on a restricted surface type for a threshold period, performing at least one of: a) notifying an operator of the MM vehicle about the travel on the restricted surface type, b) outputting a warning at an interface connected with the MM vehicle or the device, c) limiting a speed of the MM vehicle, or d) disabling operation of the MM vehicle.

A motorized vehicle assembly includes an axle comprising a channel extending along a central axis of the axle, a socket positioned within the channel of the axle, and a motorized wheel configured to be mounted on an end the axle. The motorized wheel includes a boss configured to engage the end of the axle when the motorized wheel is mounted on the axle, an electric motor, a tire mounted on the rotor, and a plug positioned within the boss, the plug configured to engage with the socket when the motorized wheel is mounted on the axle. The electric motor includes a stator fixed to the boss and a rotor surrounding the stator, the rotor configured to rotate relative to the stator. The electric motor is configured to cause the rotor to rotate relative to the stator to cause the tire to rotate.

The invention relates to a control bar for grip, traction and control of a traction unit which has the control means of the control device, steering, acceleration and possible elevation and descent integrated into the structure thereof, the control means able to be thumbwheels, push buttons, pressure sensors, a gyroscope, a joystick or any combination of the same, or electronic processing means that allow for voice recognition. It also has a control unit and another communications unit (either connected by wiring or wireless) as well as its own power supply integrated in the support structure or received from the traction unit.

A vehicle for transporting a passenger in a standing position includes a frame, a rear axle assembly disposed at a rear end of the frame, a front suspension assembly disposed at a front end of the frame, a rear deck attached to the frame to accommodate a trailing foot of the passenger, a front deck attached to the frame to accommodate a leading foot of the passenger, and a driveshaft extending forward from the rear axle assembly such that the driveshaft transmits power to the rear axle assembly.
