Abstract: Systems and methods for management of user interactions in a physical facility utilizing a studio controller and user interaction configuration are provided. A physical facility can include or define a physical space in which one or more users interact with devices, objects, or services within the physical space. Various devices can capture interaction data. The facility, via the studio controller or other process, can then process the received interaction data according to a configuration or other processing instructions. The facility, through the studio controller or other process, can generate, or cause to be generated, various outputs based on the processed interaction data.

Abstract: A service provision server collects and accumulates, for each vehicle, vehicle information obtained by an onboard device of the vehicle and environmental information related to a travel history of the vehicle. Next, the service provision server performs predictive diagnosis about necessity of maintenance for each vehicle, based on the accumulated vehicle information and environmental information, and generates maintenance prediction information that includes content and time of the maintenance, for each vehicle based on a result of the predictive diagnosis. Then, the service provision server predicts maintenance demand in an area where a maintenance business operator provides maintenance, based on the maintenance prediction information for a plurality of vehicles, and dynamically sets a maintenance price to be presented by the maintenance business operator, based on the predicted amount of maintenance demand and a reserve amount of maintenance resources reserved by the maintenance business operator.

Abstract: A screw-operated clamping mechanism comprises a clamp body, a shaft attached to a side of the clamp body, a movable pawl which is slidably attached to the shaft, a knob which is allowed to slide and turn relative to the shaft, an I-shaped nut which is rotatably screwed onto a threaded portion formed in the shaft, and a stopper attached to an end of the shaft. The knob is provided, at a side facing the I-shaped nut, with a first contact face with which the I-shaped nut comes in contact, a concave nut receiving groove formed in the first contact face, a second contact face which is formed at the bottom of the nut receiving groove and with which the I-shaped nut comes in contact, and nut locking parts which project from the first contact face and set the knob and the I-shaped nut to be turned integrally.
