    Abstract: Methods, apparatus, and computer-readable media are described herein related to using self-generated sounds for determining a worn state of a wearable computing device. A wearable computing device can transmit an audio signal. One or more sensors coupled to the wearable computing device may then receive a modified version of the audio signal. A comparison may be made between the modified version of the audio signal and at least one reference signal, where the at least one reference signal is based on the audio signal that is transmitted. Based on an output of the comparison, a determination can be made of whether the wearable computing device is being worn.

    Abstract: A technique includes communicating with a base station via a transmitter and a receiver of a first client device based on a static schedule. The static schedule indicates an uplink time and a downlink time allocated to the first client device and associated with each of multiple frames of the base station. Communication time between the base station and multiple client devices linked to the base station including the first client device is divided into multiple frames. A mode request signal is transmitted or received and performs one of: (i) requesting operation in a sleep mode for a selected number S of the frames, and (ii) indicating operation in a standby mode. An initiate signal is transmitted from the first client device to the base station via the transmitter and indicates when to begin operating in the one of the sleep mode and the standby mode.

    Abstract: This disclosure related to an audio unit of a head-mounted apparatus. The head mounted device includes a support structure with at least one side section with least one audio unit. The audio unit is transmits a first signal and a second signal. Either the first signal or the second signal is directed toward an ear of the wearer of the apparatus. The first signal may be an in-phase audio signal and the second signal maybe an out-of-phase audio signal with a 180 degree phase difference. Alternatively, both the first signal and the second signal are in-phase audio signals. The audio unit may operate in one of two modes. The first mode includes the first signal being an in-phase audio signal and the second signal being an out-of-phase audio signal. The second mode includes both the first signal and the second signal being in-phase audio signals.

    Abstract: Computer-implemented techniques are presented for a client device to wake up, independent of receiving a beacon signal, and transmit a first pilot signal to establish a link with a base station. Subsequent to waking up, the client device can perform an association process to establish the link with the base station to become “partially associated” with the base station and update the client device information at the base station. The client device information can be stored in a table at the base station, and the table can be a global table that is shared between all base stations in the wireless MIMO network. After establishing a link, the base station can inform the client device whether there is a pending call or data packet for the client device. If there is a pending call or data packet, the client device can become “fully associated” with the base station.

    Abstract: A technique includes (i) receiving a first pilot signal from a base station via a receiver of a client device, or (ii) transmitting a second pilot signal from the client device to the base station via a transmitter of the client device. First time differences and signal quality values for N samples of N respective packets in the first pilot signal are determined. Second time differences and signal quality values are received via the receiver. The second time differences and signal quality values are generated for M samples of M respective packets in the second pilot signal. An offset value is determined based on (i) the first time differences and signal quality values, or (ii) the second time differences and signal quality values. Activation or deactivation times of the receiver or the transmitter or transmission times of the transmitter are adjusted based on the offset value.
