An omni-track system for mounting onto a wheel may include a plurality of track segments. Each of the plurality of track segments may include a male connector, a female connector, a roller mount, and at least one roller. The female connector may be arranged opposite the male connector. The roller mount may be fixedly secured to the track segment. The at least one roller may be rotatably secured to the roller mount. The plurality of track segments may be linked together to fully encompass an outer circumference of the wheel.

A wearable system, such as a footwear system, can employ a generator. The generator can be an electro-mechanical generator with a portion that spins to create an electricity. The portion that spins can be spun in such a manner that it does not stop, but instead a next spin beings before a previous spin completes. This can repeat until the generator reaches a terminal velocity.

A tipping prevention unit that prevents tipping of an image forming apparatus includes shafts holding a wheel of the image forming apparatus, a shaft that abuts the image forming apparatus at a position higher than the shafts, and a shaft that contacts a floor surface on which the image forming apparatus is placed at a position further protruding to the outside of the image forming apparatus than the wheel of the image forming apparatus.

A vehicle securing apparatus is provided for pulling and securing a test vehicle provided to a vehicle testing device. The column stands on the pedestal. The vehicle securing apparatus includes a column, a traveling and rotating part, and a pedestal. The traveling and rotating part is structured to be coupled with a chain for pulling the test vehicle, and arranged coaxially with the column, and structured to travel vertically and rotate horizontally. The pedestal is structured to be attached to an arbitrary portion of a slide rail of the vehicle testing device.

A hidden braking device includes a brake handle, a brake member controlling a wheel set, and a connecting member disposed in a main frame having telescoping upper and lower frames. The connecting member has an upper stem connected to the brake handle and having fixing notches, a lower stem connected to the brake member, a locking set disposed on the lower frame and mainly including a locking unit, and an adjusting set connected to both stems. The adjusting set mainly has an operating unit on which a first spring unit is disposed, an engaging case and a positioning case disposed relative to each other, and an elastic unit located between both cases and engaged with the fixing notches. The first spring unit pushes the operating unit while loosening the locking unit to thereby position the engaging case and adjust a full length of the main frame quickly.

An omni-wheel including a hub, a plurality of rollers, and a braking system. The plurality of rollers are circumferentially arranged about the hub and arranged radially outward from the hub, where each roller of the plurality of rollers is secured to the hub by a roller mount. The braking system includes a first braking lever, having a first braking surface, pivotally secured to the roller mount, a second braking lever, having a second braking surface, pivotally secured to the roller mount, opposite the first braking lever, and an actuator arranged to rotate the first braking lever in a first rotational direction and the second braking lever in a second rotational direction. The first braking surface and the second braking surface contact at least one roller of the plurality of rollers when the first braking lever and the second braking lever are rotated by the actuator.
