Electromagnetic compatibility of power wheelchairs

Electric powered wheelchairs may be susceptible to electromagnetic interference from emissions present in the ambient environment. The proliferation of personal communication devices and radio communication have increased the ambient level of electromagnetic energy. Power wheelchairs use a variety of control input devices, wiring looms, and controllers which may be influenced by electromagnetic interference. The user may be placed at risk if the wheelchair behaves erratically in some circumstances. Methods can be applied to measure susceptibility to electromagnetic interference and reduce adverse affects
