发明名称 Infrared control system for a chair
摘要 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.
