"Hand team tic" J゛in I/i Valley was known,
Also, I encountered a lot of problems, such as having to take time to confirm the signature.

In order to eliminate this problem, for example, a device has been proposed in which all information is transmitted between the manager and the players by direct communication. This involves using a transmitter held by the coach to code the necessary instructions and transmitting them wirelessly, and the player's father, Yi Ling, converting the received code information into the required information and converting it into audio. This will be communicated to the players.

However, in this device, the player manually operates the switch ``ItL source'iu: 'III!'' at the first step of the first step, so that
For example, in the case of baseball, players sometimes forget to turn on the switch that is handed to them when they are standing at the edge of the field, and it is said that only the first players on the line can lose their power. This may cause inconvenience.

It also becomes possible to use all means to improve the transmission line density.

Next, we will discuss an example of how to identify a code in a receiver.As shown in FIG. 3, the code structure is as shown in FIG.

Let TB be the period of 1 bit during transmission, and the output of the receiving circuit 2 is 2j! (The signal time is set to 1, and the null bit is set to 0. The microcomputer 31 monitors the receiving circuit mlS2 and detects the time 10, that is, the time of deterioration from 1 to 0 on the 2nd evening.

Then, at time L after a period of time [0 to T B /2]

If the output of the receiving circuit ijlS2 is not 0 at time j t1, it is regarded as a failure and a state of waiting for the start bit is entered. jIS clock [1] When it is confirmed that the start pitch is I-, the output of the receiving circuit section 2 is
νJ out] 1゛B/l! Check IJ JυJ four times and identify the code. In the case of Figure 3, the code content is 01
Divided by 10" (all identification) The receiving circuit section 2 demodulates the transmission signal induced by the antenna 6 and outputs all code information.

This revenge. For example, a super re-biopsy wave method which has a simple configuration and is still less sensitive than the old one is used for the ili' injection. This method is used for fortune-telling, and in the case of audio signals, a sensitivity of about 1011 V can be obtained at the IRI signal strength at the input terminal of the receiver. Another method, such as a heterodyne detection method, provides a sensitivity of about 111V, but the circuit configuration is complicated and miniaturization is difficult. In terms of the number of parts, the heterogain detection method requires 5 to 10 times more than the ultra-reproduced wave detection method. On the other hand, the transmission of audio information requires a frequency band of at least 300 to 3 KHz. However, in the case of digital transmission, for example, if the total transmission speed is 100 bits per second, the basic /
The maximum i'J wave number is 5QHz, and even if its third harmonic is included, the frequency band will be 150Hz or less, and in the case of audio information, it will be 1720 or less. If you look at it the other way,
On the receiver side, the signal passband IIIlii can be narrowed to 1/20, which increases the sensitivity accordingly.

For example, if we modulate the radio wave type A2 specified by the Radio Law, the characteristics of the receiver circuit of the ultra-reproduced wave method described above are obtained as shown in Fig. 4, and the reception feeling at a bit error rate of 10-4 is
l! (A voltage of 1 to 2 μV can be obtained.Furthermore, if chip parts are used for the above He-electronic circuit, the volume will be reduced to 20 μV.)
It can be made to a size of approximately X 20 X 4 mm3, and can be formed using a hybrid IC if necessary. Therefore, a small and highly sensitive receiver 1d circuit can be realized.

At this time, power is supplied to the above-mentioned receiver from the power supply battery 4, and the receiver becomes ready to receive instruction information from the transmitter held by the director. Then, when the instruction information is transmitted from the transmitter, the receiver converts the instruction information received in the above-described manner into all voice information and transmits it to the player. When the athlete takes off the helmet 1, the switching lever 411 of the Ichigen Nuittsuchi 41 is returned to its original upright position by the force of the spring, the power switch 41 is opened, and the power supply to the receiver is stopped. As such, powering the receiver is accomplished by placing the helmet on the head without requiring any manual intervention.
