Ways to Execute the invention

in the The following is a preferred embodiment of the invention based on the attached drawings described.

The blind staff ( 1 ) consists of a handle ( 10 ), a rod body ( 20 ), a sensor system ( 30 ) and a wireless headphone ( 40 ). The handle ( 10 ) has a housing ( 11 ) that has a recording room ( 12 ) that has a cover ( 15 ) is closed. The housing ( 11 ) has through holes at one end ( 13 ) and a threaded hole ( 14 ) Mistake. The rod body ( 20 ) has a slip protection at one end ( 21 ) and at the other end a grub screw ( 22 ) on. The sensor system ( 30 ) includes four sensors to measure the distance from a solid ( 31 ), a sensor for detecting the depth of a liquid ( 32 ), a power switch ( 33 ), a button battery ( 34 ) and a vibrator ( 36 ) connected to a circuit board ( 35 ) are connected. On the circuit board ( 35 ) are a signal transmitter / receiver ( 351 ), a microprocessor ( 352 ), a sound card ( 353 ) and a buzzer ( 354 ) intended.

During installation ( 2 and 3 ) the circuit board ( 35 ), the button battery ( 34 ) and the vibrator ( 36 ) in the recording room ( 12 ) of the housing ( 11 ), whereby the four sensors ( 31 ) in the left, right, front and lower through holes ( 13 ) are recorded and the sensor ( 32 ) in the other lower through hole ( 13 ) of the housing ( 11 ) is included. The power switch ( 33 ) is at the other end of the case ( 11 ) attached. The lid ( 15 ) covers the recording room ( 12 ). Then the set screw ( 22 ) of the rod body ( 20 ) in the threaded hole ( 14 ) of the housing ( 11 ) turned.

When using the invention for a blind user ( 4 . 5 . 6 and 7 ) he can use the wireless headphones ( 40 ) carry the handle ( 10 ) grasp with one hand and the sensor system ( 30 ) with the power switch ( 33 ) switch on. If a solid barrier (such as stone or stairs) or a liquid barrier (such as puddle, moat or pond) occurs in the security area, the sensor can be used to detect the distance from a solid ( 31 ) or the sensor for detecting the depth of a liquid ( 32 ) capture this and send a signal to the signal transmitter / receiver ( 352 ) send. The signal transmitter / receiver ( 352 ) transmits this signal to the microprocessor ( 352 ), which is therefore via the sound card ( 353 ) through the buzzer ( 354 ) or the wireless headphones ( 40 ) issues a warning, the frequency of which can be changed as the barrier approaches.

When not in use or in a small room (such as an elevator), the user can use the power switch ( 33 ) of the handle ( 10 ) the sensor system ( 30 ) switch off.

If only the handle ( 10 ) is needed ( 8th ) the grub screw ( 22 ) of the rod body ( 20 ) from the threaded hole ( 14 ) of the handle ( 10 ) are turned so that the handle ( 10 ) from the rod body ( 20 ) is separated. Then the handle ( 10 ) with a fastener ( 50 ) (like Velcro) can be attached directly to the arm of the user.

When using the invention for a blind and deaf user ( 9 ) he can use the handle ( 10 ) grasp with one hand and the sensor system ( 30 ) with the power switch ( 33 ) switch on. If a solid barrier (such as stone or stairs) or a liquid barrier (such as puddle, moat or pond) occurs in the security area, the sensor can be used to detect the distance from a solid ( 31 ) or the sensor for detecting the depth of a liquid ( 32 ) capture this and send a signal to the signal transmitter / receiver ( 352 ) send. The signal transmitter / receiver ( 352 ) transmits this signal to the microprocessor ( 352 ), which is therefore due to the vibrator ( 36 ) issues a warning, the frequency of which can be changed as the barrier approaches.

following the advantages of the invention are summarized:

• 1. The four sensors for detecting the distance from a solid ( 31 ) and the sensor for detecting the depth of a liquid ( 32 ) of the sensor system ( 30 ) in the housing ( 11 ) a solid barrier (such as stone or stairs) or a liquid barrier (such as puddle, moat or pond) is detected in the security area, causing the buzzer ( 30 ) or the wireless headphones ( 40 ) can issue a warning to a blind user;
• 2. The four sensors for detecting the distance from a solid ( 31 ) and the sensor for detecting the depth of a liquid ( 32 ) of the sensor system ( 30 ) in the housing ( 11 ) a solid barrier (such as stone or stairs or a liquid barrier (such as moat or pond) is detected in the security area, causing the buzzer ( 30 ) or the wireless headphones ( 40 ) can issue a warning to a blind user whose frequency can be changed as the barrier is approached.
• 3. The four sensors for measuring the distance from a solid ( 31 ) and the sensor for detecting the depth of a

Liquid ( 32 ) of the sensor system ( 30 ) in the housing ( 11 ) a solid barrier (such as stone or stairs) or a liquid barrier (such as a moat or pond) is detected in the security area, causing the vibrator ( 36 ) by the handle ( 10 ) can generate a warning for a blind and deaf user whose frequency can be changed as the barrier is approached.

by virtue of the availability of the invention corresponds to the above facts, Progressiveness and novelty fully meet the requirements for a utility model.

The the above description is only a preferred embodiment the invention and is not intended as a definition of the limits and serve the scope of the invention. All equivalent changes and modifications belong within the scope of this invention.
