摘要： A flexible material provided at a robot is conductive and an electrical characteristic of the flexible material changes in response to a change of state. The electrical characteristic between plural detection points of the robot is detected by a detection unit. An estimation unit uses a learning model to estimate a robot state from the electrical characteristic of the robot. The learning model is trained so as to input the electrical characteristic and output the robot state. The learning model is trained using, as training data, electrical characteristics when changes of state occur at the flexible material and robot states after the changes of state of the flexible material of the robot. The estimation unit inputs the electrical characteristic to the learning model and outputs the robot state corresponding to the inputted electrical characteristic.

摘要： An inference device detects, with a detection section, an electrical characteristic between plural predetermined detection points on a vehicle seat provided with a soft material that is conductive and that exhibits a change in an electrical characteristic according to a change in pressure imparted. An inference section employs a learning model to infer a posture state of an occupant of the vehicle seat from the electrical characteristic of the vehicle seat. The electrical characteristic when pressure has been imparted to the vehicle seat and the posture state information indicating the posture state of the occupant when imparting pressure to the vehicle seat are employed as training data for a learning model trained so as to be input with the electrical characteristic and output the posture state information, and trained so as to be input with the electrical characteristic and output the posture state of the occupant corresponding to the input electrical characteristic.

摘要： A power reception apparatus (250) is installable in a vehicle (200) and configured to receive electric power from a power transmission coil (40) embedded in the ground. The power reception apparatus includes: a relay coil (70) that is arranged on a tired wheel (60), which includes a tire (62) and a wheel (64), and includes a first coil (71) and a second coil (72); a power reception coil (240); and a power reception circuit (230) connected with the power reception coil. The first coil and the second coil are connected with each other by an electrical conductor (73). The first coil is arranged inside the tire. The second coil is arranged at a position such that a distance from a central axis (61) of the tired wheel to the second coil is shorter than a distance from the central axis of the tired wheel to the first coil. The power reception coil is arranged at a position such that when the first coil faces the power transmission coil, the power reception coil faces the second coil.

摘要： The invention provides a method for accurately predicting a road surface condition at a location within a predetermined range. To that end, the road surface conditions at the location within the predetermined range are predicted using road surface estimation decision values calculated using vehicular information, which is the information on the behavior of a vehicle W i during travel obtained by an on-board sensor mounted on the vehicle, or estimated road surface conditions estimated using the road surface estimation decision values. In doing so, the road surface condition at the location within the predetermined range is predicted based on the road surface estimation decision values calculated for the location within the predetermined range or the time-dependent changes in the estimated road surface conditions.
