Abstract: When a user requests distribution of event information of a shop from a mobile phone device, an information management server responds to the request and distributes the event information of the shop to the mobile phone device. When a user visits a shop and holds a mobile phone device with an IC tag attached thereto over a shop terminal, communication takes place between the IC tag and an IC tag reader-writer of the shop terminal, and the information management server acquires a shop ID thereof from the shop terminal, and distributes shop information concerning commodities and facilities of the shop to the mobile phone device. The information management server acquires customer/shop visit information, calculates the aggregate, and distributes the aggregate customer/shop visit information to a shop information server owned by an advertiser.

Abstract: A charging system for a vehicle battery comprises a voltage detecting circuit having at least one element, such as a Zener diode, having an impedance variable in accordance with a voltage from an auxiliary rectifier connected to the armature coils of the alternator of the system. When the generating voltage is low at the initial operating period, the impedance of the voltage detecting circuit is kept high, and thus the generated current from the auxiliary rectifier is all supplied to the field coil of the alternator without being consumed by a driving circuit of a charge-indicating lamp. As the voltage from the auxiliary rectifier exceeds a predetermined voltage, the impedance of the detecting circuit lowers to cause the driving circuit to energize the lamp. The voltage detecting circuit may be constructed of one or more than one Zener diode, or of a plurality of diodes connected in the forward direction.

In this way, even if a fault such as a break occurs in the first circuit, the generating operation is maintained until the engine is turned off and the generator has stopped.
