| 20080290622 | Driving Mode Switching Apparatus and Control Method Therefor - A driving form switching apparatus enabling even a user of wheelchair who cannot freely use limb to easily change over a driving form by single hand self-operation. By using a differential gear mechanism or a combination mechanism comprising pinions and racks, the rotating, tilting and shifting motions of a steering lever are transmitted to two rotating shafts. Drums are directly coupled to the two rotating shafts, and the rotations of the two rotating shafts are transmitted to steering shafts through flexible wires as first connecting means. Also, the steering shafts for wheels are parallel- or cross-connected by second connecting means. Thus, the driving forms of a four-wheel drive vehicle such as back and forth traveling, counter-clockwise turning, clockwise turning, turning on the spot, parallel traveling, stopping and braking, etc, can be switched by a single-hand simple operation. | 11-27-2008 |

| 20120112426 | Multi-Purpose Chassis Member - The presently disclosed embodiments, as well as features and aspects thereof, are directed towards providing a modular cart system operable in multiple configurations suitable for multiple transport applications and, more particularly, for a modular cart system that includes a multi-purpose chassis member. Advantageously, embodiments of a multi-purpose chassis member include various features that provide for either the receipt of a component included in a modular cart system or, alternatively, mechanical coupling to fixtures that are exclusive from the modular cart system. Importantly, because a multi-purpose chassis member is configured for the receipt of various components that may or may not be comprised within a given cart arrangement, a modular cart system that includes a multi-purpose chassis member can be reconfigured for a custom transport solution depending on application. That is, unlike typical cart devices, a modular cart system that includes a multi-purpose chassis member can be configured and reconfigured to take the form of a cart that is most desirable or advantageous to the user. | 05-10-2012 |

The vehicle mount is configured as a heat sink such that a larger portion of the heat generated by the bearing is transferred to the heat sink as compared to the portion transferred to the axle. | 08-09-2012 |
| 20120223497 | Particulate Filled Wheel - Pneumatic tires made of a flexible elastomer material are well established for vehicles on paved roads. However, in many instances paved roads are in the minority, a rarity, or non-existent. Further many applications of motorized vehicles occur permanently off paved or unpaved surfaces where terrain is not solid but loose. Elsewhere compacted snow, very low temperatures, rocky environments, and mud present issues to pneumatic tires as does increasing vehicle weight which requires the load to be distributed across multiple wheels. It would be beneficial to have a tire that allowed for an expansion of the design space for tires that addresses the issues discussed above in a wide range of lunar and planetary environments with high load bearing. Such a tire is presented employing flexible particulate filled designs for improved drawbar pull, lateral resistance, hill climb potential, rolling resistance, and terrain accommodation. | 09-06-2012 |
