Abstract: The disclosed invention is a means of providing an individual with increased ambulatory function through the use of a wheeled chair. The chair includes a lift mechanism, which is comprised of a linkage and an actuation means that can be operated by the user without assistance from another individual. The combination enables a user of compromised physical capabilities, to locomote from one place to another and perform daily tasks that would require bending or reaching. The chair is lightweight and very mobile, thereby minimizing restrictions to the user. The lift mechanism linkage and actuation means minimizes torque on the motor of the actuation means, eliminating current draw spikes which would stall the motor when the battery is low. The lightweight and low friction linkage design maximizes the function of the invention by keeping the battery and actuation means small, thereby reducing the weight and increasing the mobility of the chair.

Abstract: The present invention relates to fluid jet interlace apparatus and related methods for interlacing filaments into a yarn with the filaments intermingled with adjacent ones of the filaments and groups of the filaments to maintain unity of the yarn by frictional constraint between the filaments at periodic nodes along the yarn. The invention also relates to methods of making fluid jet interlace apparatus.
