| PROBLEM TO BE SOLVED: To provide a method and a system for directing a movable target to a follow-up device, without complicating or increasing the constitution of a follow-up target and that of the follow-up device. SOLUTION: An automatic target follow-up system 10 has a tracking part 12, related to a follow-up device 34 and a leading part 14 related to a follow-up target. The tracking part 12 has a 1st processor 15 and at least two converters 16a, 16b for generating an encoded ultrasonic signal. Each converter has a control input part connected to the 1st processor 15, in order to generate the encoded ultrasonic signal to the leading part 15, in response to a command signal from the 1st processor 15. The encoded ultrasonic signal stores originating source identification information. A radio-frequency(RF) receiver 18 is connected to the 1st processor 15, in order to receive an encoded RF signal storing the distance and direction information of the leading part 14 from the tracking part 12, which is used for the purpose of steering the follow-up device to the direction of the follow-up target from the leading part 14. | ||||||

| PROBLEM TO BE SOLVED: To obtain an electronic distance deciding apparatus in which the distance can be decided at a relatively low cost by providing an evaluation unit for deciding the phase difference indicative of the distance between an inquiry signal and a response signal. SOLUTION: A microprocessor 4 transmits a square pulse signal FS as an inquiry signal. In response to reception of the inquiry signal FS, a response section generates and transmits a same response signal AS. An inquiry and evaluation section receives the response signal AS through a receiver and delivers it to the first input of an exclusive OR gate 6 through a response line 5. In parallel therewith, the microprocessor 4 generates an inquiry signal FS and delivers it to a delay unit 8 through a delay line 7. The delayed inquiry signal FS is delivered to the second input of exclusive OR gate 6 from the delay unit 8. So long as the distance to be determined is the difference of signal propagation delay smaller than the synchronous length of the inquiry signal FS and the response signal AS, the phase difference becomes a definite measurement of the distance. | ||||||

| PROBLEM TO BE SOLVED: To provide the method and device to decide the position of a mobile station. SOLUTION: A mobile station 10 receives (through a synchronization channel) a transmission time stamp from a base station and sends a reception time stamp to the base station accordingly (through a pseudo spurious echo carrier deviated from a data carrier). The base station uses the time stamps to calculate a 1st range. Other 2nd and 3rd base stations execute the similar operation to above to calculate 2nd and 3rd ranges. The base station calculates a position vector and an azimuth by using the ranges and calculates the longitude and the latitude of the mobile station 10. The mobile station 10 uses a silent echo generating circuit for the transmission reception of the time stamps above. COPYRIGHT: (C)1998,JPO | ||||||

| PROBLEM TO BE SOLVED: To improve the detection accuracy and the detection speed of a mobile speed in the mobile communication adopting the TDMA system by measuring the mobile speed of a mobile terminal from a transmission delay without using a received input electric field as a parameter. SOLUTION: A transmission burst signal generating circuit 3 generates a transmission time slot in synchronism with a timing signal from a burst timing generating circuit 2, a modulation demodulation circuit 5 applies modulation demodulation to the generated signal and transmits the signal. A reception time slot received by a reception circuit 7 is fed to a delay amount detection circuit 8 to detect a delay in the reception timing slot with respect to the transmission time slot. Then a mobile speed calculation circuit 9 calculates a change in the delay due to movement of a mobile terminal per unit time and reports the result to a control section 1 as a mobile speed.

| PURPOSE: To provide a method and a device for identifying items and tracking them, by adding a radio transceiver tag on the item and sending a signal between the tag and one or more interrogator sub-systems. CONSTITUTION: A tag is usually set under a low power stand-by mode unless a signal is sent by an interrogator. The interrogator carries the signal to all the tags within the receiving range, and the tag responds to it after a false random lag. When the interrogator identifies the tag, it returns the fact to the tag and the tag returns to the stand-by mode. The tag which is not identified by the interrogator sends the identifying signal again, and the process continues until all the tags within the range of the interrogator are identified.

| PURPOSE: To reduce the number of magnetic coupling circuit to be used and to eliminate the necessity of an oscillation circuit required for signal transmission and reception only by one of transmitters / receivers by totally transmitting plural signals through one magnetic coupling circuit. CONSTITUTION: At a reader / writer 1, a power supply voltage is impressed from a power supply circuit 3 to respective circuits. An oscillation circuit 5 outputs the carrier of 1MHz frequency for example and supplies the carrier to an amplitude modulation circuit 7. The carrier to be outputted from the amplitude modulation circuit 7 is sent through the magnetic coupling circuit composed of a transmission coil 9 and a reception coil 10 to an IC card 2 and converted to a direct current voltage as the power supply voltage by a rectifying / smoothing circuit 16. This power supply voltage is impressed to the respective circuits in the IC card 2 and power is applied to these circuits and supplied from the reader / writer 1 to the IC card 2. Thus, the number of transmission / reception channels is reduced and circuit constitution for transmission / reception is simplified. COPYRIGHT: (C)1991,JPO&Japio | ||||||

| PURPOSE:To decide precisely a distance by adding a range amplitude comparing circuit and a detected range number correcting circuit. CONSTITUTION:A detected amplitude value and a detected range number covering two ranges are outputted from a moving target detecting circuit, and stored in amplitude storage circuits 7a and 7b and detection range storage circuits 8a and 8b than amplitude-compared by an amplitude comparing circuit 9 to store detection range storage circuits 12a and 12b with a large-amplitude range number as a detection range number as to PRF1 and PRF2. Then, adding and subtracting circuits 13a and 13b perform addition and subtraction between selected detection range numbers xA and yA so as to correct an error of one range which is considered to occur on the basis of a real range number, and a truth decision circuit 14 reads a true/false value (1 or 0 display) on the basis the calculated range number to store the range number in latch circuits 15a and 15b when the value is true. A distance decision circuit 5 outputs a distance on the basis of the stored true range numbers (x) and (y). | ||||||

| PURPOSE:To make it possible to confirm the location of a person carring a response signal transmitting slave-device at the remote established place of a master machine, by a method wherein the master machine relays a discrimination signal among ones, which are always transmitted from the slave-devices corresponding to the number of said slave-devices, at every slave-device through a repeater to performs the transmission and reception with each slave-device and each slave-device is constituted so as to be capable of selecting the discrimination sigal transmitted by the master machine and transmitting a response signal. CONSTITUTION:When the location of a worker M1 carrying a slave-device is confirmed, among discrimination signals corresponding to slave-devices 7, 8, 9... always transmitted by a master machine 1, a discrimination signal for the slave-device 7 is received by the slave-device 7 through the repeater 2 positioned at the same floor as the slave- device 7. The slave-device 7 selects that said discrimination signal is one of itself in a selection part at the time of positional detection. When an always inherent response signal is received by the master machine 1 through the repeater 2, the master machine 1 selects the slave-device 7 and the repeater 2 from other ones to detect the positions of both of them and confirms that the worker M1 carrying the slave-device 7 is present on the fifth floor. By this mechanism, the locations of all slave-devices are successively detected and the position of each worker can be confirmed. | ||||||

| PURPOSE:To make it possible to perform each individual control of a moving object in an extremely easy manner, by specifying the existing position of a moving individual by synthetically judging the receiving levels of receiving antennas arranged at every set interval. CONSTITUTION:At least receiving antennas AR of a receiver R are arranged a large number of points P11-Pmn arranged at set intervals in a plane form. A number of lines of rows of each point among the points P11-Pmn are made same but the numbers may be not necessarily same. A receiver T is constituted of a code generating part G for fabricating a discrimination code at every individual, a transmission part TX for modulating the discrimination code fabricated in the code generating part G by a carrier to obtain a radio wave, a battery B and a timer TM for intermittently supplying power from the above-mentioned battery B to the code generating part G and the transmission part TX while a non-directional transmission antenna AT emitting a radio wave is connected to the transmission part TX. The receiver R is mainly constituted of a receiving part RX for detecting the received radio wave and a voltage-frequency converter. | ||||||

| PURPOSE:To output a positive response signal even if a received question signal level is low, by forming the response signal by treating a received and noise removed question signal with a means for receiving power supply corresponding to the level detection of said question signal. CONSTITUTION:The question signal from a question apparatus on the ground is received by an object response apparatus 2 and amplified by an amplifier 23 while the noise thereof is removed by BPF22. The level of this amplified signal is detected by a level detector 24 to control a switch circuit 25 and, only when the question signal passing the amplifier 23 is a predetermined level or more, power is supplied to a means which is constituted of frequency dividers 27-29, ROM11 and a switch 12 and generates a response code subjected to frequency deflecting modulation inherent to an object from a power source. Therefore, the generation of erroneous response caused by erroneous operation generated when the question signal is a low level is prevented and, even when the question signal level is low to a certain degree, the certain response signal is sent out to accurately perform the discrimination of the object. | ||||||
