Abstract

The intent of the invention is to prevent radio/pager users from losing their units (beeper or radio, which- ever the caSe may be). Many units are lost because users may drop them and are not aware that they have dropped them (e.g. a beeper in a crowded train station). Others might just be unaware that they misplaced the radios (e.g. the utility company worker which forgets his radio on the truck's root). This invention will alert both user and dispatcher that she/he has dropped the unit and will lose it ifleft unattended.

SHOCK-ACTIVATED PAGER/RADIO ALARM

by Eduardo Gonzalez

  The intent of the invention is to prevent radio/pager users from losing their units (beeper or radio, which- ever the caSe may be). Many units are lost because users may drop them and are not aware that they have dropped them (e.g. a beeper in a crowded train station). Others might just be unaware that they misplaced the radios
(e.g. the utility company worker which forgets his radio on the truck's root). This invention will alert both user and dispatcher that she/he has dropped the unit and will lose it ifleft unattended.

  The idea is to include as part of the fwmware, a shock-activated circuit. These exist in IC form, and it should not be too d&x& to 6nd them in surface mounted type. This IC will be part of the firmware.

  Upon detecting a shock, (From a height of 4 R or higher), the IC should send its signal to the unit's fmnware. Upon receipt, the unit must (will) beep for a period of about 10 seconds. This will, in turn, call the

user's attention to the fact that she/he no longer has the unit (in their possession). The user will then realize that she/he has dropped the radio (or beeper) and pick it up.

  In the case of a radio, the firmware should issue a double word to the Central Controller. An Extended Function ISW with a certain argument mask (numeric field) can be set aside to identify "UNIT HAS BEEN DROPPED" (see Figure 1). Upon arrival to the...
