In this paper the standard formulas for instantaneous and average power in sinusoidal systems are generalized to non-sinusoidal systems by appealing to the Hilbert Transform and Bedrosian’s Theorem for a general class of non-sinusoidal currents and

There are use cases where presenting spatial information via the tactile sense is useful (e.g., situations where visual and audio senses are not available). Conventional methods that directly attach a vibrotactile array to a user's body present spati
