Abstract: A wheelchair system includes a wheelchair including a plurality of force sensors including at least three force sensors. A rigid seat pan is placed in contact with each the plurality of force sensors at a different position on the rigid seat pan so that the rigid seat pan does not contact the frame and forces on the rigid seat pan are transferred to the plurality of force sensors. Each of the plurality of force sensors is in communicative connection with a processor system. A memory system is in communicative connection and an interface system is in connection with the processor system and a user interface system in communicative connection with the processor system. Instructions stored on the memory system are executable by the processor system to determine a value of a variable related to a distribution of force on the rigid seat pan over time.

Abstract: A wheelchair includes a frame, a seat attached to the frame, a first forward wheel on a first side of the frame and a second forward wheel on a second side of the frame, a first rearward wheel on the first side of the frame and a second rearward wheel on the second side of the frame, a first drive wheel on the first side of the frame positioned intermediate between the first forward wheel and the first rearward wheel and a second drive wheel on the second side of the frame positioned intermediate between the second forward wheel and the second rearward wheel, and actuators to independently control the vertical position of the first forward wheel relative to the frame, the vertical position of the second forward wheel relative to the frame, the vertical position of the first rearward wheel relative to the frame, the vertical position of the second rearward wheel relative to the frame, the vertical position of the first drive wheel relative to the frame and the vertical position of the second drive wheel relati

Abstract: A personal mobility device includes a control system including a manually operated actuator, a first forward control valve having an inlet in fluid connection with a source of pressurized gas and an outlet in fluid connection with a first forward port of at least a first pneumatic motor, and a first rearward control valve having an inlet in fluid connection with the source of pressurized gas and an outlet in fluid connection with a first rearward port of the first pneumatic motor. Movement of the manually operated actuator controls actuation of the first forward control valve and the first rearward control valve and thereby flow of gas from the source of pressurized gas to the first forward port and the first rearward port.

Abstract: A pathway measurement system hereof includes a rigid frame and a mobility system attached to the frame. The mobility system includes at least one movable element which is adapted to contact a surface of a pathway via which the frame may be moved relative to the pathway. The pathway measurement system further includes at least one sensor adapted to measure at least one characteristic of a pathway. The pathway measurement system has a first mode of operation in which the mobility system moves the frame along the pathway to move the at least one sensor relative to the pathway. The at least one sensor is connected to the pathway system such that a distance between the at least one sensor and an axis of rotation of one of the moveable elements remains constant in the first mode of operation. In general, the at least one sensor is isolated from any compliance or suspension system.

Abstract: Mobile water heating systems for producing hot water are disclosed herein. In one embodiment, a mobile water heating system includes a water heater having an oval-cylindrical shape. The water heater includes a shell, a lid and a water reservoir having a screen. A first heating coil and a second heating coil can extend between the screen and a first cone and a second cone, respectively. A first burner and a second burner can be configured to mix and combust fuel and air and direct the resulting flames through the heating coils. Pall rings can at least partially fill an interior volume of the water heater and the combustion of the fuel and air can heat the heating coils and the pall rings. Water can be heated by being directed through the heating coils and through a water manifold positioned to spray water on the pall rings.
