Abstract: A vibrating device includes a motor housing, an electromagnetic coil coupled to the motor housing and a motor elastically coupled to the motor housing. The motor includes a pole plate, a magnet and a yoke, the pole plate bonded to the magnet and the magnet set within the yoke. The electromagnetic coil is disposed within an annular space defined between the magnet and the yoke.

Abstract: A vibro-tactile cutaneous alert stimulation and massaging system for equipment such as a vehicle includes a pad; a heater element, and motorized vibrators in respective regions of the pad; a plurality of vibratory transducers for location relative to plural zones of the seat, each transducer being responsive to a transducer power signal; a microprocessor controller having program and variable memory and an input and output interface; an array of input elements connected to the input interface for signaling the microprocessor in response to operator input, the signaling including an intensity control value, a plurality of mode signals, and a plurality of region signals relating transducers to be enabled; and a driver circuit responsive to the output interface for producing the power signal separately for each of the transducers.

Abstract: A vehicle massaging system includes a seat pad and motorized vibrators in respective regions of the pad; and a controller for selectively activating the transducers. Each of the vibrators is in a cavity of a main cushion member, the cavity being closed by an outer cushion member that supports an occupant, a soft or resilient isolation device being interposed between the vibrator and the main cushion member for reduced coupling of vibrations to structure or other portions of the seat, but enhanced coupling to a target region of the outer cushion member for improved selectivity of particular regions of a user's body to be massaged, and in multiple seating installations, unwanted vibration of one seat is suppressed during activation of vibrators in an adjacent seat. The transducer is bonded to the outer cushion member or a reinforcing sheet that is laminated thereto, the isolation device contacting a bottom portion of the transducer. Alternatively, the isolation device can completely enclose the transducer.
