One embodiment of an electronics convenience vehicle (ECV) may include a frame, a plurality of wheels configured to support and move the frame, a seat supported by said frame, a steering mechanism disposed toward a front portion of the ECV, a motor configured to cause at least one wheel to be propelled forward, propelled backward, or to remain in a fixed position, a throttle, when activated in a first position, causes said motor to propel said at least one wheel in a forward direction, when activated in a second position, causes said motor to propel said at least one wheel in a reverse direction, at least one sensor directed to detect objects in front of a direction of travel of the ECV, and a control and communications unit (CCU) disposed in front of said seat, and configured to receive said sense signals and to control operations of said motor.

A system, method, and device for operations of an electrically motorized vehicle. The electrically motorized vehicle can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. A user of the device for the electrically motorized wheel can be profiled by receiving data from a sensor system of the device and creating a profile of the user operating the vehicle from the data.

A system, method, and device for operations of an electrically motorized vehicle. The vehicle can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. A user interface for controlling the device of the electrically motorized wheel includes at least one button displayable by the user interface to control a function associated with the device.

An apparatus including a first electrical connector; and a second electrical connector. The first and second electrical connectors have magnets to provide a magnetic holding force with each other and provide alignment of the electrical connectors to hold the second electrical connector against the first electrical connector at a predetermined position. Magnetic poles of the magnets are configured to limit orientation of the second electrical connector on the first electrical connector. The second electrical connector includes two power contacts and an interruption detector contact, where the power contacts are movably mounted on the second housing and configured to disconnect from electrical contacts of the first electrical connector, when the second electrical connector is being disconnected from the first electrical connector, only after the interruption detector contact of the second plurality of electrical contacts disconnects from an electrical contact of the first electrical connector.

Disclosed herein is a personal mobility vehicle hand control. The personal mobility vehicle hand control includes a housing, a display, a first keypad, a second keypad, and a joystick. The display is proximate an end of the housing. The first keypad is proximate the display. The second keypad is proximate an opposite end of the housing. The joystick is between the first keypad and the second keypad. At least one key of the first keypad is configurable to correspond with a function displayed on the display. At least one key of the second keypad is configurable to correspond with the same function displayed on the display.

A seat, a motion control method thereof and a motion control system thereof. The motion control method for the seat includes: acquiring images of around the seat, and tracking a current caregiver via image recognition; determining a relative position between the current caregiver and the seat; and controlling a motion of the seat based on the relative position.

A method of thermal management for an electrically motorized wheel, the method can include defining a thermally conductive path from at least one component, the at least one component becoming heated during operation of the electrically motorized wheel, providing the path with a thermally conductive material and further defining the path such that the path contacts the at least one component, further defining the path such that the path contacts a hub shell assembly of the electrically motorized wheel thereby conducting heat from the at least one component to the hub shell assembly.
