Abstract:
The technology described herein relates to auxiliary wakeup for low-power devices. In an implementation, an auxiliary path for waking up a radio frequency (RF) radio of a low-power device is disclosed. The auxiliary path includes peak detector circuitry, pattern detector circuitry and a battery switch. The peak detector circuitry is operable to detect the presence of a RF field at a RF antenna of the low-power device. The pattern detector circuitry is enabled by the presence of a RF field and is operable to detect a time pattern in an amplitude envelope of a wakeup signal received at the RF antenna of the low-power device. The battery switch is operable to connect battery power to a RF radio of the low-power device when the time pattern is detected. Once powered, the RF radio establishes communication with a wakeup device.

Claim (Index 3):
The auxiliary path of  claim 2 , further comprising:\n a capacitor communicatively coupled to the second switch and the RF antenna and operable to divide voltage from the RF antenna,\n wherein impedance of the capacitor is relatively small compared to an impedance of a matching network for the RF radio.
