Abstract: Embodiments of a wheel and a brake mechanism for use with a non-motorized cart such as a shopping cart are disclosed. In some embodiments the wheel has a hub having a plurality of first engagement features, and the brake mechanism includes at least one second engagement feature that can be moved between an unactuated position and an actuated position. In the unactuated position, the second engagement feature does not engage any of the plurality of first engagement features on the hub, and in the actuated position, the second engagement feature operatively engages at least one of the first engagement features in order to provide a braking force that locks the wheel. A magnetically-activated trigger maintains the second engagement feature in the unactuated position. In response to a triggering magnetic field, the trigger is released and allows the second engagement feature to move from the unactuated position to the actuated position.

Abstract: Brake mechanisms for a wheel of non-motorized wheeled vehicle such as, e.g., a shopping cart, are described. In various embodiments, the brake mechanism can provide a variable amount of braking force or torque between zero and an amount sufficient to lock the wheel. In some embodiments, the brake mechanism includes a brake plate that is movable toward and away from a surface of the wheel hub along a direction parallel to the rotation axis of the wheel. The brake plate is configured not to rotate when the wheel and hub are rotating. Factional engagement between the brake plate and the surface of the wheel hub provides the braking force. The brake plate and/or the surface of the wheel hub can include engagement features such as, e.g., protrusions and slots, hi some embodiments, the brake mechanism fits entirely within the wheel.

Abstract: An embodiment of a light powered transmitter (100) configured for broadcasting an electromagnetic control field to a region is provided. The transmitter comprises a housing (110) having a longitudinal axis. The housing comprises a photovoltaic cell configured to generate electrical power in response to light and a rechargeable power source configured to store at least a portion of the power generated by the photovoltaic cell. The housing also comprises an electromagnetic transmitter and a directional antenna. The directional antenna can be configured to broadcast an electromagnetic (e.g., radio-frequency) control field to a region. The directional antenna can be rotatably mounted in the housing such that the antenna can be rotated around the longitudinal axis. The housing can further comprise a transparent or translucent optical element (120) configured to receive the light and converge at least a portion of the light onto the photovoltaic cell.
