SELF-STABILIZING SKATEBOARD
A self-stabilizing, one-wheeled electric skateboard may include improved features. In some examples, the vehicle includes a status indicator viewable through a slot formed in an upper surface of the board. In some examples, the vehicle includes a convertible carrying handle transitionable between stowed and deployed positions. In some examples, the vehicle includes an interchangeable fender and fender substitute that may be removably coupled to an upper surface of the board. In some examples, a motor controller of the vehicle may operate a field-oriented control (FOC) scheme configured to control the electric motor by manipulating a direct current aligned with a rotating rotor flux angle and a quadrature current defined at ninety degrees from the rotating rotor flux angle. In some examples, the motor controller may be configured to permit intuitive dismounting of the vehicle by tilting and/or moving the vehicle backward.
SELF-STABILIZING SKATEBOARD
A self-propelled, one-wheeled vehicle may include a board having two deck portions each having a concave front footpad configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. The concave front footpad has a rider detection sensor in the form of a membrane switch conforming to the shape of the footpad (e.g., facilitated by one or more slots formed in the membrane switch). A motor assembly drives the vehicle in response to board orientation and rider detection information.

SUSPENSION SYSTEM FOR A ONE-WHEELED VEHICLE
A self-propelled, one-wheeled vehicle includes a suspension system configured to dampen up-and-down motion of a board relative to the axle of a central wheel assembly when the vehicle encounters obstacles (e.g., bumps) on a riding surface. Illustrative suspension systems include a shock absorber and a swingarm that couple the axle to the board. The suspension system may be disposed completely below a foot deck of the vehicle.

SYSTEMS AND METHODS FOR SCANNING AN EMERGENCY RESPONSE VEHICLE FOR A TOOL
A system includes an emergency response vehicle transitionable between a motive state and a non-motive state and a tool. The tool includes an identifier and is configured to be removably secured to the emergency response vehicle. The system further includes a scanner coupled to the emergency response vehicle and operable to identify the identifier when the tool is secured to the emergency response vehicle. A control module is communicatively coupled to the scanner and includes a processor and a memory storing instructions which cause the processor to determine that the emergency response vehicle has transitioned between the motive state and the non-motive state, and, in response to determining that the emergency response vehicle has transitioned between the motive state and the non-motive state, cause the scanner to scan the emergency response vehicle for the identifier to determine whether the tool is secured to the emergency response vehicle.

Balancing vehicle and control method therefor
A balancing vehicle includes a wheel, a bracket, a frame, a shock absorbing member, pedals, a control rod, and a handle. The bracket is fixed to an axle of the wheel. The frame is slidably connected to the bracket through a slider fixedly connected to the bracket, so as to allow the frame to slide relative to the bracket. The shock absorbing member is disposed between the frame and the bracket, and is configured to cushion relative movement between the frame and the bracket. The pedals are fixed to the frame. The control rod is configured to move back and forth in a direction of travel. The balancing vehicle accelerates when the control rod is pushed forward in the traveling direction, and the balancing vehicle decelerates or retreats when the control rod is pulled backward in the traveling direction. The handle is coupled to a top of the control rod.

Surface detection for micromobility vehicles
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.
