摘要:
A digital radio communication system (200) uses a repeater (216) to relay calls which can not be completed in a direct talk-around mode between two radios. The repeater (216) establishes early synchronization in advance of a pending call by listening to an originator radio (204) attempt to make a direct talk-around call to a target radio (210). Asynchronous digital two-way radio communication systems can benefit from the reduction in voice call connect time.
摘要:
An electronic device (100) having a battery (116) with an associated battery voltage. The battery (116) includes a plurality of cells configured to form a plurality of battery portions (116A and 116B). The electronic device (100) also includes a regulator (102), a first circuit (118), and a swith control circuit (106). The regulator (102) operates on the battery voltage and produces a regulated voltage. The first circuit (118) operated on the battery voltage. The switch control circuit (106) alternately applies the regulated voltage to the plurality of battery portions (116A and 116B) so as to charge the battery (116).
