Abstract: The present invention is intended to provide a wheelchair that has a seat height that is adjustable from a standard position to a height at which the users eye level can be the same as that of most standing persons. A gas strut (15, figure 6) is provided to enable the seat to be raised or lowered with the user seated. A main frame 5 is connected to a chassis frame 1 by a front hinge 4 and rear link arm assemblies 19. This allows the main frame to be folded flat (figure 8) to aid storage and transportation. Two independent hand wheels 8 drive the rear wheels 2 via two drive belts 10,11. The hand wheels are connected to the seat 7, and therefore as the seat position is altered the hand wheels remain with the seat thus allowing the wheelchair to be propelled by the user when the seat is in any position. Alternatives to the gas strut and belt drives are discussed.

Abstract: A finger-atachable device for sensing liquid levels by lowering it to the surface of a liquid comprises a member (1) which is preferably a housing which is adapted to fit a human finger, a float or piston (6) which is held in moveable relationship to the member and which, when the device is downwardly directed, is lower than the member and which is lifted relative to the member when it contacts a body of liquid and thereby brings an element (4) into contact with a finger in the member whereby the level of the liquid is sensed by the user of the device by touch. The housing may comprise a resilient member adapted to grip a human finger or a substantially non-resilient structure which maybe of thimble shape. The float may be surrounded by a member to protect it from damage and which may be removable for cleaning. The element (4) may be part of or an extension of the float. The device may be used with food or drink, hot, cold or dangerous liquids and by blind people.
