Abstract

A large part of the paging market is made up of people in the construction, or construction related industries, such as contractors, plumbers, electricians, county inspectors and real estate agents. These people generally have a need for a device for making mea- surements, such as a tape measure. It is possible to satisfy both the paging and measurement needs of these people by integrating a pager and a tape measure into a single package.

PAGER WITH INTEGRATED ELECTRONIC MEASURING DEVICE

by Rodney S. Whaley, Paul Gorday, Eric T Eaton, Salvador Sibecas and Adrian Napoles

  A large part of the paging market is made up of people in the construction, or construction related industries, such as contractors, plumbers, electricians, county inspectors and real estate agents. These people generally have a need for a device for making mea- surements, such as a tape measure. It is possible to satisfy both the paging and measurement needs of these people by integrating a pager and a tape measure into a single package.

  Figure 1 shows one embodiment of a device in which the pager is combined with an electronic measuring device, such as one using infra-red, ultrasonic or radio waRmeaSurement technologies. By combining the pager with the electronic measuring device, various circuit functions used in the pager, such as the microcomputer for signal processing and the LCD display for displaying messages can also be utilized to provide the measurement functions. An electrical block diagram showing the inter-

action of circuit functions is shown in Fiie 2. By sharing common circuit functions, the package size and cost of the integrated pager/electronic measuring device is less than the size and cost ofhvo separate devices.

  Figure 3 shows a second embodiment of a device in which the pager is combined with a mechanical meas- uring device. The measuring device inc...
