Also a novel method for measuring and adjusting the amount time spent applying and releasing pressure. In some embodiments, rather than simply measure time spent applying pressure, the system will allow the user to “buy back” sit time when the user releases pressure. The rate at which the system will credit the user with a “buy back” of sitting time may in some embodiments be directly proportional to the amount of time the user spends performing a pressure release. 1. A system comprising:at least one sensor capable of measuring force or pressure applied by a portion of the body of a user;a speaker;a memory; initialize a sit timer in the memory;', 'run the sit timer while the force or pressure measured by the at least one sensor is greater than a release threshold;', 'cause the speaker to sound an alarm in an event the sit timer reaches a predetermined sit time limit before the user performs a release having a predetermined full release duration;', 'detect a first release event occurring prior to the sit timer reaching the sit time limit, wherein the measured force or pressure is less than the release threshold during the first release event; and', 'based on the detected first release event, provide the user additional time until the alarm is sounded., 'a processor operably coupled to receive force or pressure measurements from the at least one sensor, the processor programmed to2.

A front suspension system for an electric wheelchair includes front pivot shaft, a front wheel retainer, an elasticity resistance member, and a front shock absorber. The front shock absorber is disposed on a horizontal first section of the front wheel retainer so as to improve climbing capability of the wheelchair. The elasticity resistance member is disposed between the frame and the front wheel retainer and has two ends connected to the front wheel retainer and the abutting member of the frame, respectively. When the front wheels encounters bumpy road and makes the front wheel retainer pivot, the elasticity resistance member will be compressed to produce a reaction force toward the front wheel retainer and the abutting member of the frame, respectively, so that the front wheel retainer is pressed down to keep pressing against the flat bearing surface, and the frame is also pressed downward to prevent tipping backward. 1. A front suspension system for an electric wheelchair , being assembled onto a frame of the electric wheelchair and provided for mounting of two front wheels which are disposed at one end of the frame , at another end of the frame being provided two rear wheels , to each of two sides between the two ends of the frame being pivotally fixed one end of an assembling frame via a pivot , the front suspension system comprising a front pivot shaft , a front wheel retainer , an elasticity resistance member , and a front shock absorber , wherein the front pivot shaft has one end fixed to the frame , and the front wheel retainer has two ends fixed to the front pivot shaft and the front wheels , respectively , the front suspension system being characterized in that:an abutting member is on the frame;a surface of the front wheel retainer facing the frame is formed with a driving portion, the front wheel retainer includes a first section, a second section, and a third section which are connected sequentially with one another, an extending direction of the first ...

A wheelchair suspension system which includes two springs with at least one damper and a central movable component that attaches to a wheel on a wheelchair. The damper is positioned in the center of at least one of the two springs and resists sudden force acting against the wheelchair with the two springs, the central movable component moves either in an upward or downward direction when there is force acting on it from both the springs and damper or by the uneven terrain. The wheelchair suspension apparatus will create greater stability for the entire wheelchair and increase the comfort of the user.
