Abstract: A radio-frequency power transmitter. The radio-frequency power transmitter includes an array of patch antennas, an array of phase modulators, each phase modulator having an input port and associated with one or more of the patch antennas, a local oscillator that provides an oscillatory signal to the input port of each of the phase modulators, an array of amplifiers, each amplifier receiving an input from one of the phase modulators, and a microprocessor configured to interface with the array of phase modulators and control a holistic radiative power transmission vector pattern generated by the radio-frequency power transmitter.

Abstract: Exercise apparatus includes rotatable horizontal cylinder supporting user in a wide variety of exercises. Transversely spaced elongated handles extend from behind and lower than the cylinder upward and forward to substantially higher than the cylinder. The frame, cylinder, and elongated handles arranged so that user's body is supported primarily by the cylinder while user's hands can grasp the elongated handles sequentially higher and lower positions and can selectively pull and push translating user's body fore and aft on the cylinder. In exemplary embodiment, handles are bowed with upper portions positioned substantially above said cylinder to enable user sitting on said cylinder to reach upward and grasp handle upper portions, and frame includes transversely spaced posts, handles include portions extending downward to engage posts. Other features include lower handle set, vertically adjustable cylinder and soft surface cylinder and handles.
