A parking assist system for a vehicle includes a target position setting unit setting a vehicle target parking position on the basis of a coil type and position of a power transmitting unit. When the coil type is a composite coil having a configuration such that an annular coil wound to surround a first axis and a solenoid coil wound to surround a second axis intersecting with the first axis are serially connected, the target position setting unit sets the target parking position such that a center of a power receiving unit mounted on the vehicle is located at a predetermined distance from the first axis along the second axis. The solenoid coil is set at a position with respect to the annular coil such that the first axis extends through a side face center portion of the solenoid coil.

A power transmitting device includes: a power transmitting unit being able to contactlessly transmit electric power to a power receiving unit of a power receiving device; and a guide unit changing a guide position of the power receiving device at power reception of the power receiving device on the basis of a type of the power receiving unit. The guide unit may when the types of the power receiving and transmitting units are the same, set a position of the power receiving unit, at which center positions of the power receiving and transmitting units coincide with each other, for the guide position, and, when the types of the power receiving and transmitting units are different, set a position of the power receiving unit, at which the center positions of the power receiving and transmitting units deviate from each other, for the guide position.

With an object of providing an artificial sphincter for which repeated shape changes are possible, and for which the quantity of shape change is sufficient so as to be used as a substitute for a large natural sphincter, an artificial sphincter that opens and closes, as required, either the anus of a living body or part of the intestine led outside the body is provided, wherein this artificial sphincter comprises a pair of shape memory alloy elements that change reversibly between two opposite shapes upon changes in temperature and hinges that link the shape memory alloy elements together in a cylindrical shape.

In at least two separated devices, a data transmission or a power transmission is performed through the electromagnetic coupling of coils which are arranged in mutually facing positions in the respective devices. In order to reduce the effect of a displacement between two coils even if the two coils are displaced from each other, the inner diameter of a coil,on the side of a station, as a primary coil, for performing the data transmission or the power transmission, is set to be larger than the inner diameter of a coil,on a watch side, as a secondary coil, by at least 1 mm.
