    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： Systems and methods are provided for managing medical devices. In one embodiment, medical device usage data is stored on the medical device to indicate the usage, health, and alarm or error codes. The usage data is electronically read and assessed against one or more thresholds to determine if the medical device is operating properly and, hence, can be inventoried for reuse, or is need of service or repair. Other embodiments are also disclosed wherein the medical device wirelessly scan its environment to ensure, for example, the device is used with approved accessories or components and personnel. In yet other embodiments, medical devices are provided that can configure themselves for operation by scanning any connected components for component-specific operational data. The operational data is then used to configure the medical device to operate with the component.

    摘要： Systems and methods are provided that obtain the same or better level of performance by using lower operating flow rates and pressures within the system. This extends the life of system components and lower energy consumption. In one embodiment, gas separation (or sieve) beds that are used to separate gaseous components are provided that have lower flow and pressure requirements compared to conventional beds. The sieve beds include, for example, a diffuser having low solid area in cross-section and maximum open area for flow while providing adequate mechanical properties to contain sieve material and support filter media. In another embodiment, systems and methods are provided having an indicator when a component has been serviced or repaired. This provides an indication whether the component has been tampered with in any manner. This allows the manufacturer to determine if the component was serviced, repaired, or tampered with outside the manufacturer's domain.

    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： 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.
