    摘要： Various embodiments are described herein for a method of communicating between a main processor of a mobile device and a battery for providing power to the device. In general terms the method comprises providing a communication interface (132) between the main processor (102) and the battery (130) to provide communication therebetween; sending a protocol version request packet (460) from the main processor (102) to the battery (130); initiating authentication (610) of the battery (130) by the main processor (102) if the battery (130) provides (604) a protocol version response packet to the main processor (102) in response to the sending a protocol version request packet; and reading a battery ID resistor of the battery (130) if the battery (130) does not provide a protocol version response packet to the main processor (102) in response to the sending (602) a protocol version request packet.

    摘要： Based on bounds of a period of reduced operation (404) for a base device (110), a base device generates a power management message (410) for transmission to a peripheral device (120). In the power management message, the base device inserts bounds of a period of reduced operation for the peripheral device. As a result, the periods of reduced operation conserve battery power in both devices and the two devices may reestablish a communications channel upon reaching the end of the period of reduced operation and resuming normal operations.

    摘要： A wireless device (104,106) may alert a wireless smart card reader (102) that communication of data between the wireless device (104,106) and the wireless smart card reader (102) is probably imminent by sending an activation alert. Upon receipt of the activation alert, if the wireless smart card reader (102) is in a low-power state, the wireless smart card reader (102) may enter a higher-power state. If the wireless smart card reader (102) is in the higher-power state upon receipt of the activation alert, the wireless smart card reader (102) may remain in the higher-power state until a timeout period has expired. The wireless device (104,106) may instruct the wireless smart card reader (102) to enter the low-power state by sending a deactivation alert if the wireless device (104,106) identifies that communication of data between the wireless device (102,106) and the wireless smart card reader (102) is not likely to occur within a specified period of time.
