Modular safety device with dog deterrent and panic alarm

Abstract

A modular safety device has an ultrasonic device capable of transmitting ultrasonic sound with a frequency of at least 20 kHz. The ultrasonic sound is inaudible to human ear and can cause barking or approaching dogs to stay in place, stop or move away from the user. The modular safety device also includes a power supply and an audible alarm device. The audible alarm device is capable of issuing a distress sound audible to human ear. The power supply, ultrasonic device and audible alarm device are incorporated into a detachable and portable unit that can be easily carried on a user's person or attached to a user's mobile device such as walker or wheelchair.

1 . A modular safety device comprising:
 an ultrasonic device capable of transmitting ultrasonic sound with a frequency of at least 20 kHz,   wherein said ultrasonic sound is inaudible to human ear,   wherein said ultrasonic sound remains audible to barking or approaching dogs, and is capable causing such dogs to stay in place, stop or move away from the user;   a power supply communicably coupled to said ultrasonic device;   an audible alarm device communicably coupled to said power supply,   wherein said audible alarm device is capable of issuing a distress sound audible to human ear, and   wherein said power supply, ultrasonic device and audible alarm device form a detachable portable unit that can be easily carried on a user's person or attached to a user's mobile device such as walker or wheelchair.   
   
   
       2 . The modular safety device of  claim 1  further comprising a location tracer device for determining a user's location. 
   
   
       3 . The modular safety device of  claim 1  further comprising a compass for determining travel direction. 
   
   
       4 . The modular safety device of  claim 1  wherein the distress sound issued by the audible alarm device is at least 75 dB. 
   
   
       5 . The modular safety device of  claim 1  wherein the location tracer device is capable of determining the location of a user by employing a Global Positioning Satellite (GPS). 
   
   
       6 . A modular safety device comprising:
 a means for transmitting ultrasonic sound with a frequency of at least 20 kHz,   wherein said ultrasonic sound is inaudible to human ear,   wherein said ultrasonic sound remains audible to barking or approaching dogs, and is capable causing such dogs to stay in place, stop or move away from the user;   a means for supplying power communicably coupled to said means for transmitting ultrasonic sound;   a means for issuing an audible alarm communicably coupled to said means for supplying power,   wherein said means for issuing an audible alarm is capable of issuing a distress sound audible to human ear, and   wherein said means for supplying power, means for issuing ultrasonic sound and means for issuing an audible alarm are incorporated into a detachable and portable unit that can be easily carried on a user's person or attached to a user's mobile device such as walker or wheelchair.   
   
   
       7 . The modular safety device of  claim 6  further comprising a location tracer means for determining a user's location. 
   
   
       8 . The modular safety device of  claim 6  further comprising a means for determining travel direction. 
   
   
       9 . The modular safety device of  claim 6  wherein the distress sound issued by the audible alarm means is at least 75 dB. 
   
   
       10 . The modular safety device of  claim 6  wherein the location tracer means is capable of determining the location of a user by employing a Global Positioning Satellite (GPS).
