Abstract: As an expert gives instructions to cause movements of their own hands transferred directly as tactile force sense while perceiving surrounding information of a collaborator on a real-time basis and watching the collaborator's line-of-sight end and movements of the collaborator's hands, the collaborator indirectly receives the instructions of the expert's manual skills, which are the expert's tacit knowledge, on a real-time basis while sharing realistic sensations with the expert who is at a remote location when the collaborator performs an act of working with their own hands.

Abstract: An artificial leg motion assisting apparatus and an artificial leg motion assisting method which are capable of transmitting knee joint motive power to a commercially-available trans-femoral prosthesis without making a wearer feel a sense of discomfort. When the artificial leg motion assisting apparatus is attached to the commercially-available trans-femoral prosthesis, a control unit controls a drive unit by a specified control method on the basis of mechanical impedance adjusted by an impedance adjustment unit and transmits output of the drive unit to a knee joint coupling.

Abstract: Proposed are a functional improvement evaluation apparatus and a nerve cell culture apparatus of model animals capable of performing feedback control, even to mammalian model animals, based on biosignals in the same manner has humans based on a relatively simple configuration. The present invention comprises a biosignal detection unit which is mounted on a central side above an intended in vivo site of a mammalian model animal and/or a peripheral side below an intended in vivo site of a mammalian model animal, and detects a biosignal resulting from a biological activity of the model animal, a control unit which causes a driving source to generate power according to an intent of the model animal based on the biosignal detected by the biosignal detection unit, and a motion transmission mechanism which is connected to a holding part for holding a foot of each leg of the model animal, and transmits the power of the driving source to the holding part so that the holding part swings at a same or approximate trajectory as a natural walking motion pattern of the model animal, and the control unit controls the power of the driving source based on a swing state of the holding part connected to the motion transmission mechanism.

Abstract: According to the present invention, various biological signals can be measured at an appropriate position without depending on an expert. A biological-signal measurement device includes a sensor 1 that is in contact with a nerve fiber N and detects a nerve action potential generated in the nerve fiber N, a signal processor 2 that is connected to the sensor 1 via wiring 5, the signal processor 2 obtaining a signal based on the nerve action potential from the sensor 1 and wirelessly transmitting the obtained signal, and a receiving/transmitting unit 3 that receives the signal from the signal processor 2. The sensor 1 and the signal processor 2 are embedded in a body. The receiving/transmitting unit 3 receives the signal from the signal processor 2 via skin S.

Abstract: Noninvasive natural healing in daily life or regenerative cell treatment can be promoted. A knee joint model is constructed by three-dimensionally analyzing measurement data obtained by measuring an outline shape and internal space shape of a knee joint part of a subject; a transition state towards an orthotic direction for a symptom improvement of the knee joint part is simulated continuously or stepwisely with reference to the knee joint model; and an exoskeleton mold capable of continuously or stepwisely finely adjusting the knee joint part towards the orthotic direction is designed based on the transition state.

Abstract: Provided are an object identification device and an object identification method in which objects can be easily identified. The object identification device is provided with a pixel group extraction unit which scans, in units of the image area, an X-ray transferred image obtained from an imaging unit which performs X-ray imaging to an item to be inspected that is supplied, and extracts a plurality of pixel groups including characteristics of a shape of at least a part of the item to be inspected, and a determination unit which determines, with regard to the plurality of pixel groups extracted by the pixel group extraction unit, whether the item to be inspected corresponds to the object by executing all of the series of mappings related to an angle of an n direction by using each of the weight parameters based on the data group read from the memory unit.

Abstract: An upper limb motion support apparatus and an upper limb motion support system which are capable of significantly improving the enhancement of an operator's work efficiency and the reduction of their workload are proposed. A controller which causes an articulated arm and an end effector to perform three-dimensional motion according to the operator's intention based on a biological signal acquired by a biological signal detection unit causes the articulated arm and the end effector to perform cooperative motion in conjunction with the operator's upper limb motion by referring to content recognized by an upper limb motion recognition unit.
