    It is not unusual to find applications where of inactivity, but will then latch this POR and use it while it is desirable to have an initial Power-ON to disable the power supply to the POR detector cir- Reset there is a strong desire to avoid them being cuit so that it cannot create more resets until the created every...

    Same frequency simulcast systems need to maintain relatively close launch times between their transmitter sites. Usually in the order of microsec- onds. There may be other paging systems in the sur- rounding area, but as long as they do not have a mutual interference area or utilize different RF channels, there...

    Call count barring is not a new feature to the paging industry. It has existed across several differ- ent paging infrastructure platforms with slight varia- tions in implementation for many years. This fea- ture allows a paging carrier or system operator to limit the number of messages a subscriber may receive during...

    As the number and complexity of sensors and electronic control units in automobiles continues to rise, the difficulty in effectively integrating the elec- tronic systems grows. This paper outlines a chassis control system architecture intended to case the interfacing of sensors to the Electronic Control Units (ECUs)...

    The ideal testing environment for RF equipment is non-reflective, non-reverberant, and provides suf- ficient isolation from the ambient RF environment. A conducting enclosure provides a very high degree of isolation from the environment but is, by defini- tion, a reflective and reverberant environment because the...

    Desense (receiver interference caused by digital circuit noise) is becoming a greater problem as pagers shrink in physical size and digital circuits move closer to the antenna. (The microprocessor is not more than 1 cm away from the antenna in many modem pager designs.) A major cause of desense is the crowbar, or...

    AFCO Project 25 Common Air Interface (CAI) specifications call for use of the Digital Slotted Multiple Access (DSMA) method for subscriber radio inbound data traffic. This DSMA method defines a protocol to be used for channel access that minimizes collisions on the inbound channel. To be effective in avoiding...

    In a typical one-way messaging environment, all base stations transmit the same information signal at approximately the same time (simulcast). This results in delay spread and multipath interference. In the delay-spread case, the same signal arrives at the receiver at different times. Depending on the amount of delay,...
