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. The controller responds to the input elements to activate the transducers in: a massaging mode selectively producing activation of the drive signals at adjustable intensity corresponding to the intensity control value; and an alert mode producing a predetermined sequence of vibro-tactile cutaneous alert stimulation cycles, each alert stimulation cycle having idle portion between 1 and 30 seconds, and an active portion of sufficient duration, frequency, and intensity for selectively stimulating the muscle groups of the driver for improving the driver's alertness, the intensity of vibration in the alert mode being greater than the maximum intensity in the massaging mode. Additional transducers can be spaced along a restraining seat belt for imparting directionally oriented stimuli warning of an impending collision. Also disclosed are methods for alerting a vehicle driver and for tactile-signaling a directionally oriented external condition to a vehicle driver or occupant.

A massaging system includes a pad comprising with multiple zones sand vibratory transducers in the pad for vibrating the zones. Each transducer includes a motor and a mass element eccentrically coupled to the motor. The massaging system also includes a microcontroller having an input interface and an output interface, a program memory coupled to the microcontroller, and input elements coupled to the input interface for signaling the microcontroller in response to operator input. A motor driver coupled to the output interface and the vibratory transducers drives the vibratory transducers in response to the operator input, while firmware stored in the memory and executed by the microcontroller selectively operates the vibratory transducers in a tapping mode and a wave mode in response to the operator input.

A massaging system includes a pad; a heater element, and motorized vibrators in respective regions of the pad; corresponding heater and motor drivers in the pad; a control wand removably connectable to the pad and having a microcontroller with RAM and ROM, a serial EEPROM; a serial interface to a shift register in the pad for signaling pulse width modulation of the drivers. The ROM defines a master set of operating modes and variations thereof in response to operator input of intensity, region, heat input; and mode signals to the controller. The EEPROM has data for implementing and configuring a subset of the master modes. The system can also provide composite modes including a test mode that automatically sequentially activates each mode and variation of the subset of the modes without delays for exercising non-implemented modes. The system can have a power detector for identifying sources of power having different current limitations, the system being operated with PWM duty cycle limiting when raw power voltage falls below a preset level. Also disclosed is a set-up method for writing data to the EEPROM using the serial interface when the wand is disconnected from the pad for facilitating production of a variety of systems with reduced inventory requirements. The system can also include an audio envelope detector having a dual-slope integrating ADC in the pad that is cycled by serial signals driving the shift register, a single comparator output of the ADC signaling the microcontroller.

A remote controlled massage device includes a remote control unit having a microprocessor, a keypad, and a transmitter, the microprocessor being programmed for generating output data directly corresponding to individual keystrokes of the keypad that define activation of particular vibrator elements, operation in particular time-variant power level sequences, relative vibration intensity, and relative speed of advancing through the time-variant power sequences. The transmitter has a transducer for radiating signals corresponding to the output data, for reflection from a ceiling under which the device is located, the data being transmitted in plural identical packets having a header, a sequence number, a device code program data, and an error code, subsequent sets of the identical packets having different sequence numbers. A massage unit of the device includes a cushion; electrically powered vibrator elements in the cushion; a detector supportable in an upwardly directed orientation relative to the cushion for receiving the reflected radiation signals; and a micro controller system electrically connected for driving the vibrator elements in a plurality of modes having variant power levels in response to the detector, the packets being validated using the error code and a settable device code of the massage unit, storing the sequence number of a last-received valid packet. Next-received valid packets having sequence numbers matching that of a last-received valid packet are ignored.

The motors can be variably driven using pulse-width modulation, with duty cycle compensation for voltage drops resulting from added loads, and with current limiting when, for example, the system is powered from an AC line using a low-voltage transformer of limited capacity. Also disclosed is a corresponding method for massaging. The system can have a power detector for identifying sources of power having greater and lesser voltage drops as loads are added, the controller being programmed for increasing a base duty cycle and reducing a load increment duty cycle during operation from the power source of lesser voltage drop. A configuration selector can signal particular components being electrically connected in the system for utilizing a single set of programmed instructions in the program memory in variously configured examples of the massaging system. The system can also include an audio detector having an audio mode input element for selectively activating the motors in response to a detected envelope of an external audio signal. The system can also include a test mode that automatically sequentially activates components of the system.
