Прикованному к инвалидному креслу 43-летнему японцу Сэйдзи Утида (Seiji Uchida) не удалось покорить 4164-метровую вершину Брейтгорн (Breithorn) в швейцарских Альпах с помощью силового роботизированного костюма HAL (Hybrid Assistive Limb). В то же время мечта инвалида частично сбылась — до самого крутого подъёма горы он всё же добрался.

(EN)A motion assistance device has a biological signal detection means for detecting a biological signal from the wearer of the device; a motion assistance device installation member having a drive source for applying torque acting to the wearer by use of each joint of the wearer as a rotating shaft; a control means for controlling the drive source to generate torque corresponding to the biological signal detected by the biological signal detection mean; a drive torque estimation means for estimating the drive torque generated by the drive source; a joint angle detection means for detecting angular displacement of a joint; and a parameter identification means for substituting the drive torque estimated by the drive torque estimation means and the angular displacement detected by the joint angle detection means into an equation of motion to specify the wearer-specific dynamics parameter, the equation relating to the entire system and including wearer-specific dynamics parameter. The control means controls the drive source according to a predetermined control method, based on the equation of motion into which the dynamics parameter identified by the parameter identification means is substituted.

Various embodiments of a biological interface system and related methods are disclosed. The system may comprise a sensor comprising a plurality of electrodes for detecting multicellular signals emanating from one or more living cells of a patient and a processing unit configured to receive the multicellular signals from the sensor and process the multicellular signals to produce a processed signal. The processing unit may be configured to transmit the processed signal to a controlled device that is configured to receive the processed signal. The system is configured to perform an integrated patient training routine to generate one or more system configuration parameters that are used by the processing unit to produce the processed signal.

Various embodiments of an ambulation system and a movement assist system are disclosed. For example, an ambulation system for a patient may comprise a biological interface apparatus and an ambulation assist apparatus. The biological interface apparatus may comprise a sensor having a plurality of electrodes for detecting multicellular signals, a processing unit configured to receive the multicellular signals from the sensor, process the multicellular signals to produce a processed signal, and transmit the processed signal to a controlled device. The ambulation assist apparatus may comprise a rigid structure configured to provide support between a portion of the patient’s body and a surface. Data may be transferred from the ambulation assist apparatus to the biological interface apparatus.

The control system for the Berkeley lower extremity exoskeleton (BLEEX) requires ground contact pressure information to operate safely and effectively. Commercially available in-sole sensors do not have sufficient bandwidth, accuracy and reliability for such a system. We have designed and prototyped an in-sole ground contact sensor that uses MEMS pressure transducers placed in an array of hermetically sealed cavities. This system provides a robust method to monitor ground contact pressures.
