Abstract: A method for controlling an information processing apparatus having an OS, capable of appropriately executing a process related to a program for executing an administrator authority requiring process. The method comprising: when receiving an operation from a predetermined account in a predetermined OS environment, executing a first process for installing a first program regardless whether the predetermined account is an administrator account or a non-administrator account; when receiving an operation from the predetermined account in an OS environment which is not the predetermined OS environment, executing a second process for activating a third program for installing a second program regardless whether the predetermined account is the administrator account or the non-administrator account; and executing a third process for installing the second program when the third program is activated and execution of an administrator authority requiring process is permitted.

Abstract: A method, of the present disclosure, of evaluating a tire ground contact property includes mounting a tire on one surface of a flat plate; placing a predetermined load on the tire or placing the tire in a no-load state; irradiating the tire with terahertz waves having a frequency of 0.1 THz to 10 THz from the other surface side of the flat plate or from inside the flat plate, the wavelength of the terahertz waves being greater than the roughness average length in at least a portion of the one surface of the flat plate and/or greater than the roughness average height in at least a portion of the one surface of the flat plate; detecting reflected terahertz waves from the tire; and evaluating the ground contact property of the tire on the basis of the detection result.

Abstract: An intra-tire power generating apparatus capable of producing high power is provided. The apparatus includes rotary magnets and rotary weights, which rotate in response to variations in centrifugal force and circumferential acceleration working on the tire of a running vehicle, and a coil unit, which is located between two rotary magnets facing each other and generates voltages through electromagnetic induction from the rotary magnets. In the apparatus, the rotary magnets and the rotary weights have an identical center line of rotation. The rotary weights are so formed as to have their center of gravity dislocated from the center line of rotation. The rotary magnets are each provided, in the plane orthogonal to the center line of rotation, with an even number of regions adjoining in the circumferential direction around the center line of rotation, the adjoining regions having different magnetic poles from each other.

Abstract: This invention provides a tire (10) equipped with a sensor (14), attached to a rubber member (15) in the surface of the tire (10), for detecting deformation of the tire (10). The sensor (14) is adhered to the rubber member (15) with the aid of an elastic adhesive formed of a room-temperature moisture cure adhesive agent composed mainly of an acryl modified silicone resin or the like. The adhesive between the sensor (14) and the rubber member (15) is cured to form an elastic adhesive layer (16). According to the above constitution, the deformation of the rubber member (15) in the tire surface can be transmitted to the sensor (14) with high accuracy, and, at the same time, the durability of the sensor (14) can be improved.
