Abstract: A testing system and test cartridge for analyzing a sample of water from a water source for specific analyte levels. The test cartridge including a membrane filter that captures a target analyte while allowing a labelled conjugate to permeate through the membrane. The conjugate includes an analyte-specific labelled binding reagent to bind with the target analyte for optical detection. The direct membrane interrogation (i.e., on-filter detection), determines analyte levels without elution of the analyte from a filter thereby improving analyte recovering and assay sensitivity.

Abstract: The vehicle comprises a base and a seat moveable along a curve having a focal point. The vehicle is adjustable to position an occupant in the seat to achieve a desired position for the center of gravity of the occupant relative to the focal point of the curve. A method for minimizing effort required to tilt the seat of a personal mobility vehicle comprises the steps of providing a personal mobility vehicle having a seat that is adapted to move along an arc having a center of curvature, positioning the seat substantially horizontally, providing an occupant in the seat, and adjusting the position of the vehicle occupant's center of gravity so that the center of gravity is substantially equal to or below the center of curvature of the arc.

Abstract: A seat cover, and a method for producing a seat cover, minimizes surface tension in the cover material, when the cover conforms to a highly contoured shape.

Abstract: A foldable wheelchair comprises a substantially horizontally extending upper side frame member. An upper end of an axle plate is secured to the upper side frame member. An axle housing is secured to the axle plate. A cross brace is pivotally secured directly to the axle plate at the lower end of the axle plate. A wheel mount assembly comprises an axle sleeve mount having an internal thread. An axle sleeve has an external thread that is in threaded engagement with the internal thread of the axle sleeve mount. The axle sleeve has an internal bore that accepts a wheel axle. The internal bore is angled with respect to the axis of the external threads to provide camber to a wheel. The axle sleeve is adapted to provide lateral adjustment to the wheel by rotating the axle sleeve within the axle sleeve mount any number of complete revolutions.

Abstract: A wheel mount may generally be comprised of an axle plate and a camber tube clamp that may be height adjustable with respect to the axle plate. The camber tube clamp can be selectively mountable upright or inverted so as to increase an overall range of height adjustability. The camber tube clamp can be mountable in front of or behind the axle plate so as to increase an overall range of center-of-gravity adjustability. The camber tube clamp and the axle plate may have an interlocking feature that may allow the camber tube clamp to slide vertically along the axle plate to facilitate height adjustment. A seat collar can be positioned at various locations along a wheelchair frame for center-of-gravity adjustment. The axle plate can be detached from and attached to the seat tube collar to allow the axle plate and camber tube clamp to be reverse mounted in order to increase the range of center of gravity adjustment.

Abstract: An angle adjustable camber assembly is adapted to support the wheel of a wheelchair having a seat, the rear of which is at a given rear seat height. The assembly comprises a movable member for supporting the wheel. The movable member is adapted to translate and rotate so as to be able to selectively position the wheel at any one of a variety of camber angles while substantially maintaining the rear seat height and a spacing between the top of the wheel and the seat frame.

At least one of the mating members has a generally curved radial surface that is engageable with the other mating members to lock together the backrest with respect to frame.

Abstract: A level on a wheelchair allows the cambered rear wheels to be easily adjusted to eliminate toe-in/toe-out. The level comprises a ball encased in a curved track. The curve track is formed in a clear housing that mounts to the underside of a wheelchair camber tube or wheel axle. The camber tube or wheel axle is rotated until the ball aligns with an indicator mark indicating that toe-in/out has been eliminated from the cambered wheels.

Abstract: A center-of-gravity tilt-in-space wheelchair includes a base, a seat for supporting an occupant, and tracks supporting the seat for selective seat movement relative to the base. Wheels are adapted to support the base relative to a supporting surface. The tracks serve as rolling or sliding surfaces that allow the seat to rotate with respect to the base. Each track has a constant-radius arc with a focal point that is adapted to be coincident with the center of gravity of the wheelchair occupant. A low-friction supports the base relative to the seat. The low-friction support may include low friction elements that mate with the tracks to support for the tracks. The support can be adjustable to permit the overall tilt angle range of the tracks to be adjusted. The wheelchair seat can be adjusted to maintain the focal point of the constant-radius arc of the tracks coincident with the center of gravity of the wheelchair occupant. The front and rear wheels can be adjusted fore and aft relative to the focal point.

Abstract: A wheel mount assembly adapted for use in securing a camber tube to a wheelchair frame comprises an axle plate, at least one axially displaceable member adapted to be fixed in relation to the axle plate, and at least one radially displaceable member adjacent the axially displaceable members. The axially displaceable member is adapted to be axially displaced to cause the radially displaceable member to be displaced to tighten against the camber tube to hold the camber tube in place.

Abstract: A power wheelchair incorporates inclinometers to measure angle of pitch and angle of roll. An inclinometer signal is used as an input to a controller. The controller alters drive parameters, such as maximum acceleration, deceleration, and minimum turning radius according to the pitch angle and roll angle of the terrain upon which the wheelchair is operated.

Abstract: An improved wheel assembly comprises a caster swivel post that is adapted to pivot about a pivot axis transverse to the caster swivel post. A caster fork is supported for rotation relative to the caster swivel post and rotatably supports a caster wheel. The caster swivel post is adapted selectively pivot about the pivot axis that is transverse to the caster swivel post or be held in a substantially fixed position. A setscrew can be threadable into an upper end of a pivot nut to hold the pivot nut and thus the caster swivel post in a fixed position within the housing.
