Definitions

• the invention relates to a device according to the preamble of claim 1.
• the object of the invention is to provide people with a device with which they can optionally identify themselves to other people with their wishes and can receive a preliminary confirmation signal if one or more people with the same desired profile around them are manageable Distance, without first addressing other people.
• the device itself should be such that the person cannot immediately be recognized as the type of the seeker or the type of the respondent. Rather, the person should be able to ventilate or preserve their anonymity at will. All devices are excluded, e.g. Direction finders and direction finders with their high expenditure on equipment. Cell phones are also out of the question for a variety of reasons. Desk phones, cassette recorders or related devices are also excluded. Wristwatches are best suited because they can easily hide the first use in the sense of the invention behind the usual main use. Pocket watches can also be used, although they are usually not worn in swimwear on the beach. In principle, pocket devices such as pocket ies are also possible, although women usually carry pocket calculators less often than men.
• 1 is a top view of a clock
• Fig. 4 is a side view of a circuit board with components and battery and
• Fig. 5 is a top view of a pocket device.
• a wristwatch has a bracelet 11 and a watch case 12.
• the top of the watch case 12 has a display panel 13 in LCD technology for the time, a display panel 14 for the date and an LCD display panel 16 for the invention.
• the display field 16 can contain digits from 000 - 999 or from AAA - 777. In the present case, the number combination 333 was entered. This is done by entering the 1s with a key 17, the 10s with a key 18 and the 100s with a key 19.
• the number combination 333 means according to an agreed assignment that the specific combination of the property E 8 + E 12 + E ⁇ + E ⁇ + E 3 - + .... + E 72 is expected and / or has itself.
• E 8 can mean, for example, "age between 25 and 30 years”.
• E- ⁇ can mean "size between 178 to 183 cm”.
• the property E 35 can mean "male” and the property E 72 can mean "impulsive property"
• a coding 666 or PQR corresponds to other properties, namely properties No. 21, 30, 39, 48 and 93 3 and 4, a loop antenna 22 is located on a circuit board 21. Because of better radiation properties, the watch case 12 is made of plastic. The loop antenna 22 can both transmit and receive.
• the transmitting unit 23 is active when transmitting and the receiving unit 24 when receiving. Both the received and the transmitted signal pass through a surface filter 26 and a surface filter 27.
• the transmission unit 23 and the reception unit 24 operate in half-duplex mode.
• a microprocessor 28 controls the transmission unit when it transmits and evaluates what the reception unit 24 receives. It controls an induction transmitter 29 which controls a piezo device 31 which can cause a watch bottom 32 to vibrate.
• a battery 33 is controlled by the microprocessor 28. It will have to deliver more power when it is transmitting and less when it is only receiving, and even less when the watch is only operating as a normal watch. This control takes place via the current control 34, which in turn is controlled by the microprocessor 28
• the keys 17, 18, 19 correspond to the input field 36.
• the microprocessor 28 converts this input into the display in the display field 16
• the symbolically represented structural units 37 sit on the circuit board 21, which correspond to the boxes in FIG. 3.
• the battery is also shown
• the transmission frequency is 433.92 MHz.This is a frequency that is free for the industry.
• the frequency stability is ⁇ 75 kHz.
• the technology of the surface wave filter 26, 27 is the SAW technology % selected
• the modulation frequency is 2.5 kHz (5 kbaud / NRZ format)
• the transmission power of the loop antenna 22 is -20 dBm, these data are all applicable to the transmitter
• the receiver has the same frequency, the same frequency stability and the same SAW technology.
• the demodulation is of the ASK type.
• the settling time is approx 10 ms.
• the sensitivity is approx. -106 dBm at BER 1%, 10 kbaud (NRZ format).
• the first intermediate frequency is 500 kHz.
• the questioning device receives two pulse trains each.
• the questioning device receives two pulse trains each.
• the pocket device 42 has, for example, a format of 6 cm x 8 cm.
• An antenna 38 is provided on the right side.
• a solar field 39 either supplies the necessary electricity completely and directly or to a battery.
• the pocket device 42 can be switched on with a key 41 and the pocket device 42 can be switched off with the key 43.
• the time can be displayed in field 44.
• Field 46 shows the distance to a responding device. In the pocket device 46, the received field strength at the antenna 28 is converted into the distance that is specified in the field 46. With a key 47, the pocket device 42 can be switched to "passive".
• a red LED 48 indicates that no one is answering.
• a green LED 49 indicates that response signals are being received.
• the pocket device With the key 51 the pocket device can be switched to "active".
• a three-digit code can be displayed with the fields 52 and the code which is reproduced in the fields 52 can be entered with the ten keys 53, which allow entering from "0" to "9".
