  • Radio apparatus and communication system utilizing the same
    Patent number: 8385255
    Abstract: Using as a reference a known signal assigned to one of a plurality of streams that constitute a packet signal, a control unit applies a cyclic timing shift to known signals assigned to the other streams so as to produce packet signals which are to be transmitted finally. While varying the amount of timing shift, the control unit produces a plurality of packet signals and appends an identification number, with which to uniquely identify each of the plurality of produced packet signals, to each of the packet signals. A baseband processing unit and the like transmit, as a transmission rate inquiry signal, a packet signal constituted by a plurality of streams where the amounts of timing shift are made to differ, and receive a response signal to which the same identification number is appended for the inquiry signal.

  • Charging system for vehicles
    Patent number: 8311690
    Abstract: A charging system provided for vehicles prevents theft of a charging cable, insertion of foreign matter into a vehicle-side receptacle, or tampering when an onboard battery usable for running power is charged from a household power supply. A cable connector of the charging cable is opposed to the vehicle-side receptacle in a connecting part to prepare for charging. When a PHV is exited, a switching command switching from an unlocked state of a door locking mechanism to a locked state is inputted to a PHV ECU responsive to an inputting manipulation performed on a key or door key sensor. The PHV ECU allows the door locking mechanism to switch from the unlocked state to the locked state. The PHV ECU allows locking mechanisms to switch from the unlocked states to the locked states in the manner interlocked with the switching action of the door locking mechanism.
