Technical Examples

On-premises pager loss is reduced by alerting patrons they are out of range. Pagers include an LCD with messages or promotions. An LED on the pager emits different colors indicating the level of battery charge. Circuitry in the pager causes a higher charge to be delivered to the battery when the pager is first coupled to a charging unit, and a lower charge to be delivered thereafter. Stacked slots in the charging unit receive the pagers. This permits access without disconnection of pagers in other slots and removal from the slots using first-in-first-out rotation. Charging rails on the charging unit simultaneously and directly connect each pager in the slots. Charging units are electrically coupled to other units in a daisy chain. A light on the unit indicates whether it is receiving power. Conductors on the pagers mechanically interlock with the charging rail when a pager is inserted into a slot.
