摘要:
An angle sensor can be re-mounted properly. This angle sensor includes a detecting sensor that detects a turned volume of a rotary shaft, and a governor connected to the detecting sensor. The governor includes a comparator that compares a turned angle data obtained before the angle sensor is detached with a turned angle data obtained after the angle sensor is re-mounted. This angle sensor produces a remarkable advantage when it is used in cars which are governed using the data about a turned volume of the steering wheel or the shaft.

In a rotation-angle detector, a first detector detects a movement of a driven body following the rotation of a change gear engaged with a rotary gear of a rotary body, and outputs the detection result as a detection signal which gradually increases or decreases. At the same time, a second detector detects a rotation of a detecting gear engaged with the change gear or directly with the rotary gear of the rotary body and outputs the detection result as a detection signal which repeats continuously. A detecting circuit detects a rotation angle of the rotary body based on these two detection signals. This structure allows the rotation-angle detector to produce a smaller detection error, and be downsized. Further, only a simple calculation in the detecting circuit is necessary.

Information transmitting station transmits code division multiplexed information to many mobile units via a satellite. An information receiving apparatus is mounted on each automobile running on the ground and it receives the multiplexed information. In this information receiving apparatus, a self-position calculating section detects the position of the automobile using GPS, a PN code setting section retrieves a PN code corresponding to the position of the automobile from a table containing the correspondence of the two, and an information receiving section extracts the information related to the position of the automobile from the multiplexed information based on the retrieved PN code.
摘要:
A terminal apparatus which a user holds detects location information of the user, and transmits the location information to a management server. The management server determines whether the user is within a specific area based on the location information. When the user is in the specific area, the management server offers a service at a discount rate based on service contents registered in a storage device beforehand, and bills an entrepreneur in the specific area an amount corresponding to the discount rate as a share amount.
摘要:
A satellite communication system has a plurality of transmitting stations, a plurality of receiving stations, and a system control station in a 1 to N system configuration to which the demand-assignment principles are applied for effective utilization of frequencies. A transmission request transmitting units transmits a transmission request to the system control station. A circuit assigning unit assigns a circuit in response to the transmission request. A main information transmitting unit transmits main information to a number of indefinite receiving stations through a circuit which has been assigned. A list-of-transmitting-stations transmitting unit transmits a list of transmitting stations to which circuits have been assigned to each of the receiving stations. Based on the list of transmitting stations, a reception request transmitting unit selects a certain transmitting station from the list of transmitting stations and transmits a reception request with respect to the selected transmitting station to the system control station. A circuit indicating unit indicates a circuit of the selected transmitting station to the receiving station from which the reception request has been transmitted, in response to the reception request. A main information receiving unit receives the main information from the main information transmitting unit of the corresponding transmitting station through the circuit which has been indicated.
