Apparatus and methods for communicating with a low duty cycle wireless device
First Claim
1. A low duty cycle wireless device comprising:
- a high data rate transceiver;
a low data rate receiver for receiving a command to receive display information at the high data rate transceiver and, in response, producing a wake up signal; and
a microprocessor receiving the wake up signal and, in response, waking up from a sleep mode and activating the high data rate transceiver to receive the display information, the microprocessor deactivating the high data rate transceiver once the display information has been received.

Abstract
A low duty cycle wireless device is disclosed. The low duty cycle wireless device includes a high data rate transceiver, a low data rate receiver, and a microprocessor. The low data rate receiver receives a command to receive a large amount of information. The display information far exceeds the capacity for reception through the low data rate receiver. In response to the received command, the microprocessor wakes up from a sleep mode and activates the high data rate transceiver to receive the display information. The microprocessor deactivates the high data rate transceiver once the display information has been received.

9. A method for communicating with a low duty cycle wireless device having a display, the method comprising:
-
receiving a command by a low data rate receiver indicating display information needs to be received at a high data rate;
producing a wake up signal, in response to receiving the command;
activating a high data rate transceiver to receive the display information, in response to the wake up signal;
receiving the display information by the high data rate transceiver; and
deactivating the high data rate transceiver upon completion of receiving the display information. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A low duty cycle wireless device comprising:
-
a bi-stable display;
a high data rate transceiver;
a low data rate receiver for receiving a command to update the bi-stable display and producing a wake up signal; and
a microprocessor, in response to the wake up signal, waking up from a sleep mode and activating the high data rate transceiver to receive display information, the microprocessor activating the bi-stable display to display the received display information, the microprocessor deactivating both the bi-stable display and the high data rate transceiver once the display information has been displayed. - View Dependent Claims (17, 18, 19, 20)
