Abstract: An all-in-one propulsion system for a wheelchair is disclosed. The all-in-one propulsion system integrates the described propulsion system with the power source and the controller. In some embodiments, the power source is removably coupleable to the elongated axle housing. In some embodiments, the elongated axle housing comprises a drive mechanism housing. The drive mechanism housing may for example be positioned between first and second axle housings. An engaging portion may be defined on an outer surface of the drive mechanism housing. The engaging portion of the drive mechanism housing may be matingly engageable with an engaging portion defined on a power source housing which comprises the power source.

Abstract: An electric wheelchair propulsion system for a wheelchair. The propulsion system has a first and a second torque transfer hub rotatably mounted to a respective first and second drive wheel of the wheelchair, and an elongated axle tube arranged between the first and second hubs. First and second motors are arranged within the axle tube extending from opposing ends thereof. First and second drive axles are insertable into bores of the first and second hubs respectively, and are operatively connected to the first and second motors respectively. Means are provided to control the actuation of the motors. Actuation of the motors drives a rotation thereof, transferring a torque to the drive axles. The drive axles in turn transfer a torque to the hubs, thereby rotating the drive wheels.

Abstract: An engine knock control system that can be digitally reconfigured to operate in different knock signal processing modes. The system includes a knock detection circuit that processes an incoming knock signal produced by a vibration or pressure sensor on the engine. The circuit includes a plurality of circuit devices that are capable of being interconnected in different circuit topology configurations to thereby process the knock signal in a selected one of a plurality of different modes. The circuit includes hardware and software for forming a selected interconnection configuration of the circuit devices in response to a coded data signal input to the circuit.
