摘要： Wheeled vehicles, such as wheelchairs, that are adapted to traverse obstacles are provided. The wheeled vehicles include a frame, drive wheels, front anti-tip wheels positioned in front of the drive wheels and rear anti-tip wheels positioned behind the drive wheels. One exemplary vehicle includes front anti-tip wheels supported by rigid arms that are fixed to the frame and drive assemblies that are independently suspended from the frame. Another exemplary vehicle includes a linkage that links the front and rear anti-tip wheels, such that movement of one of the front or rear anti-tip wheel relative to the frame causes movement of the other wheel relative to the frame.

摘要： Embodiments of gas concentrating systems and methods are provided. These systems and methods comprise configuration of hardware and software components to monitor various sensors associated the systems and methods of concentrating gas as described herein. These hardware and software components are further configured to utilize information obtained from sensors throughout the system to perform certain data analysis tasks. Through analysis, the system may, for example, calculate a time to failure for one or more system components, generate alarms to warn a user of pending component failure, modify system settings to improve functionality in differing environmental conditions, modify system operation to conserve energy, and/or determine optimal setting configurations based on sensor feedback.

摘要： Gas concentrating systems and methods are provided. In one embodiment, a gas concentrating system and method is provided that includes component heat management. The heat management system can include, for example, one or more air cooling paths. The air cooling paths direct cooling air into and out of component spaces having heat-generating mechanisms. In other embodiments, the heat management system can also include component spaces that are insulated against the heat of heat-generating components. By cooling heat-generating components and insulating other components from heat, reduced wear and extended component life can be achieved. This reduces component failure and costly service to repair or replace failed or worn components. Also, gas concentrating systems and methods are provided for mounting system components with or without the use fasteners and in combination with or without component heat management.

摘要： A wheelchair suspension comprises a frame, at least one pivot arm, at least one front caster, at least one rear caster, a stabilizing system, and a sensor. The pivot arm is coupled to the frame. The front caster is coupled to the pivot arm. The rear caster is coupled to the frame. The stabilizing system is coupled to the frame and the pivot arm. The sensor is arranged such that tipping of the frame causes actuation of the stabilizing system to at least partially resist further movement of the frame.

摘要： Embodiments of a wheelchair and suspension system are provided. The suspension includes a drive assembly that is pivotably connected to a base frame at multiple locations. In one embodiment, the connection is via intermediary pivoting links or arms. Embodiments of the links or arms including rigid links, resilient links, elastic links, shocks, springs, gas cylinders and lockable gas cylinders (or combinations of the foregoing). The drive assembly can, via the pivot connections, pivot to accommodate and traverse variations and obstacles on ground surfaces.

摘要： A wheelchair suspension includes a frame, a drive assembly pivot arm, a drive assembly, a front caster pivot arm, a front caster, and a spring and shock absorbing assembly. The drive assembly pivot arm is pivotally connected to the frame. The drive assembly includes a drive wheel and is mounted to the drive assembly pivot arm. The front caster pivot arm is pivotally mounted to the frame and coupled to the drive assembly pivot arm. The front caster is coupled to the at least one front caster pivot arm. The spring and shock absorbing assembly is pivotally connected to the drive assembly pivot arm at a first pivotal connection and pivotally connected to the front caster pivot arm at a second pivotal connection. The first and second pivotal connections are positioned such that a majority of the force applied by the spring and shock absorbing assembly is applied to the drive wheel when the suspension is on a flat, horizontal support surface.
