Abstract

As more complex data services become available the use of single directional data communication (e.g. RF signals, electrical signals etc.) to a piece of hardware (pager, watch, computer, phone or other combinations) can be expanded using a transducer, which is already present in most of these devices, for bi-directional data communications.

NON-CONTACT DATA TRANSFER INTERFACE

by Stefan Peana and Daniel Peana

   As more complex data services become available the use of single directional data communication (e.g. RF signals, electrical signals etc.) to a piece of hardware (pager, watch, computer, phone or other combinations) can be expanded using a transducer, which is already present in most of these devices, for bi-directional data communications.

   Typical pagers on the market today receive data input through an RF signal sent from a terminal. The pager decodes the signal and alerts the user through a transducer alert. One possibility is the use of the pagertransducer coupled acoustically to a telephone as a bi-directional means of communication with a paging service. The ad- ditional pager hardware to accommodate a bi-directional acoustic port is minimal, see figure 1.

   Many new paging features can now be realized with the use of the bi-directional telephone communication capabilities. Roaming pagers can be programmed with a new RF address through telephone interface, thus eliminating the problems associated with "overthe air programming" when the user arrives in a new area where his RF address is already assigned. Use of the telephone line will help unload the rf channel if long instruction strings are to be sent to specific pagers at the user's request. Also, the bi-directional telephone interface can be used with full duplex communications prot...
