Wheel state monitering system and wheel state detecting apparatus

Abstract: A tire pressure monitoring system, that includes a plurality of the wheel state detection unit, provided at wheel of a vehicle, and that transmits detected wheel state information. A request signal transmitter transmits a request signal to request transmission of the detected wheel state information. When each wheel state detection unit receives the request signal, it transmits the detected wheel state together with the indication information indicating that the wheel state is detected in response to the transmission request signal. The ECU sets a determination threshold value for triggering an alert regarding tire pressure based on the detected wheel state information transmitted from the plurality of wheel state detection units.

Vehicle power supply apparatus and vehicle window member

Abstract: The vehicle power supply apparatus 100 has a power transmitting unit 110 including a power transmission side coil 111 for generating an alternating magnetic field, a positioning member 112 for positioning the power transmission side coil 111 in a vehicle 20 , and a power transmission side circuit 114 supplying an electric current to the power transmission side coil 111 ; and a power receiving unit 120 including a power receipt side coil 121 disposed in a rear window member 30 which is a non-magnetic portion of the vehicle 20 and generating an induced current based on an alternating magnetic field generated by the power transmission side coil 111 and a power receipt side circuit 122 supplying, to a power-supplied object, electric power based on the induced current generated by the power receipt side coil 121.

Variable valve timing mechanism for internal combustion engine

Abstract: A variable valve timing mechanism of an internal combustion engine varies the valve timing by varying the rotation phase of the camshaft with respect to a reference rotation phase of the drive shaft of the engine The mechanism has a first rotation member and a second rotation member The first rotation member rotates in fixed synchronism with the drive shaft and has at least one recess therein The second rotation member is located within the first rotation member and rotates integrally with the camshaft The second rotation member has a vane within the recess The vane is movable between two walls of the recess and divides the recess into first and second pressure chambers Hydraulic fluid pressure causes relative rotation of the second rotation member with respect to the first rotation member by applying pressure to the first and second pressure chambers to move the vane The mechanism further has a lock device The lock device restricts the relative rotation of the second rotation member with respect to the first rotation member such that the vane is kept between the two recess walls when the engine is cranking The lock device is released after the engine reaches a predetermined running condition
