Ralph 124C 41+ — the ‘Hypnobioscope’ (head-worn sleep-state learning device) (1911-04)

  • id: gernsback-hypnobioscope
  • corpus: fictional
  • form factor: headband
  • creator: Hugo Gernsback
  • disclosure: Gernsback, Hugo. Ralph 124C 41+, serialized in Modern Electrics beginning April 1911 (book edition 1925); the ‘Hypnobioscope’ — a head-worn device that transmits printed/spoken information into the brain of a sleeping wearer for learning during sleep.
  • ip status: fictional

  • prior art notes: Discloses a head-worn device used during sleep that delivers information into the wearer’s brain — i.e. a wearable sleep-state learning/stimulation device. Relevant to sleep-stimulation and sleep-learning wearable claims combining ‘a head-worn transducer’, ‘operation during the wearer’s sleep’, and ‘delivery of a stimulus/content keyed to sleep state’. § 103 motivation that the wearable sleep-learning device was an articulated objective by 1911 — the deep antecedent for the modern sleep-headband patent space. Cf. [[strange-days-squid-recorder]].

  • Doraemon — ‘Take-copter’ (head-worn thought-controlled flight device) (1969-12) — doraemon-take-copter [fictional] — Fujiko F. Fujio. Doraemon (manga), Shogakukan, serialization began December 1969; the ‘Take-copter’ — a small propeller unit affixed to the head (or other body part) that lifts and flies the wearer, s…

    Neuromancer — ‘trodes’ (head-worn cyberspace interface) and ‘simstim’ (worn sensory-broadcast rig) (1982-07)

  • id: neuromancer-cyberspace-deck-trodes-and-simstim
  • corpus: fictional
  • form factor: headband
  • creator: William Gibson
  • disclosure: Gibson, William. ‘Burning Chrome’, Omni, July 1982 (and Neuromancer, Ace Books, 1984); ‘simstim’ — a worn rig that records and broadcasts one person’s complete sensory experience for another to inhabit — and the head-worn electrode set (‘trodes’) by which a ‘console cowboy’ jacks into the ‘matrix’/cyberspace.
  • ip status: fictional
  • sensors: sensor-dry-eeg-electrode

  • prior art notes: Discloses (a) a head-worn, non-implanted electrode set providing bidirectional neural interface to a virtual/data environment, and (b) a worn rig that captures one wearer’s full multisensory stream and broadcasts it for another to experience. Relevant to wearable-BCI and wearable-sensory-broadcast claims. § 103 motivation as of 1982 — predating [[strange-days-squid-recorder]] (1995) for sensory broadcast, and a head-worn (non-implanted) alternative to [[the-matrix-headjack]]. Non-enabling.

  • Inspector Gadget’s headgear (‘Gadget-copter’ hat) (1983-09-12) — inspector-gadget-gadget-hat [fictional] — Inspector Gadget (DIC animated series), premiered 1983; the protagonist’s hat houses an array of voice-commanded deployable mechanisms — a helicopter rotor, a parachute, springs, and more.

    Strange Days — SQUID head-worn neural experience recorder (1995-10-13)

  • id: strange-days-squid-recorder
  • corpus: fictional
  • form factor: cap
  • creator: Kathryn Bigelow / James Cameron (writer) / Lightstorm
  • disclosure: Strange Days (Lightstorm Entertainment / 20th Century Fox), released October 13, 1995; the ‘SQUID’ — a fine wire-mesh cap worn under a hat that records the wearer’s full multisensory and emotional experience directly from the cerebral cortex for later playback into another person’s cortex.
  • ip status: fictional
  • sensors: sensor-dry-eeg-electrode, sensor-eeg
  • prior art notes: Discloses a head-worn mesh of scalp electrodes that records a rich, multi-channel signal of the wearer’s perceptual and affective experience for storage and later replay. Relevant to wearable neural-recording claims combining ‘a head-worn array of scalp electrodes’, ‘acquisition of a multi-channel cortical signal’, ‘encoding of perceptual/affective content’, and ‘storage for later playback’. § 103 motivation that the wearable experience-recording headset was an articulated objective by 1995. Non-enabling on the encoding/playback; pair with enabling EEG/BCI art.

Surrogates — head-worn neural interface rig for robot-body telepresence (2005-08-17)

  • id: surrogates-neural-teleoperation-rig
  • corpus: fictional
  • form factor: headband
  • creator: Robert Venditti and Brett Weldele
  • disclosure: Venditti, Robert; Weldele, Brett. The Surrogates #1. Top Shelf Productions, 2005 (film adaptation: Touchstone Pictures, 2009); operators recline in a chair wearing a head-mounted neural interface that captures their volition and sensory channels to remotely embody and control a humanoid robot ‘surrogate’, receiving its sensory feedback in return.
  • ip status: fictional
  • sensors: sensor-dry-eeg-electrode, sensor-eeg
  • prior art notes: Discloses a head-worn neural-interface rig that reads the wearer’s motor intent and routes sensory feedback, used to teleoperate a humanoid robot with the operator perceiving through the robot’s sensors. Relevant to wearable-BCI teleoperation claims combining ‘a head-worn neural sensor array’, ‘decoding of motor intent’, ‘transmission of commands to a remote robot’, and ‘return of the robot’s sensory data to the wearer’. § 103 motivation that the wearable neural-interface telepresence rig was an articulated objective by 2005. Non-enabling; pair with enabling BCI/teleop art.

Emotiv EPOC (2009) — 14-channel wireless saline-electrode consumer EEG headset (2009-12)

  • id: emotiv-epoc-2009
  • corpus: private
  • form factor: headband
  • creator: Emotiv Systems
  • disclosure: Emotiv Systems. ‘EPOC’ EEG headset, released December 2009 — a 14-channel (plus 2 reference) wireless headset with saline-felt electrodes covering frontal/temporal/parietal/occipital sites, with SDKs for mental-command, facial-expression and ‘affective’ detections.
  • ip status: patented
  • sensors: sensor-saline-eeg-electrode, sensor-eeg
  • algorithms: algo-cognitive-workload, algo-emotion-recognition, algo-bci-motor-imagery
  • prior art notes: Discloses a wireless multi-channel (14+2) consumer EEG headset with saline-wetted contact electrodes at standard scalp sites and on-device/SDK classifiers for mental commands, facial expressions, and affective states. Anticipates multi-channel consumer-EEG-headset claims combining ‘a wireless head-worn array of ≥8 contact electrodes’, ‘wet/saline electrode coupling’, and ‘classification of cognitive/affective state or intent’ from 2009. Product-side anchor for the headband/cap × EEG cross-cut.

OpenBCI Cyton — open-source 8-channel biosignal (EEG/EMG/ECG) acquisition board and 3D-printed headset (2014-01-22)

As open-hardware prior art it is unencumbered: any claim reciting a multi-channel head-worn biopotential acquisition device with the features published here (since 2014) reads on OpenBCI. Anchors the open bucket for biosignal wearables; relevant to headband/cap EEG and to EMG/ECG wearable claims.
