Fast timing acquisition for discontinuous reception (DRX)

Techniques performed by a User Equipment (UE) are provided for fast timing acquisition for Discontinuous Reception (DRX) cycles. The UE determines one or more System Frame Number (SFN) hypotheses. Each of the one or more SFN hypothesis can represent a possible SFN at which the UE can wake up from a sleep state of a Discontinuous Reception (DRX) cycle. For at least one of the one or more SFN hypotheses, the UE generates a detection metric based at least partially on a Physical Broadcast Channel (PBCH) sequence received from a base station, and determines, based on a value of the detection metric, whether the at least one SFN hypothesis represents a current SFN in accordance with a clock source used the base station for communicating with the UE. Other aspects, embodiments, and features are also claimed and described.

Low power heartbeat for low power mode

A first die is communicatively coupled to a first isolation communication channel and a second isolation communication channel and configured to send a first heartbeat signal over the first isolation communication channel. A second die is coupled to receive the first heartbeat signal from the first die over the first isolation communication channel and to supply a second heartbeat signal to the second isolation communication channel. The first die enters a first die low power mode responsive to detecting an absence of the second heartbeat signal and the second die enters a second die low power mode responsive to detecting an absence of the first heartbeat signal. The first and second die use low power oscillators in the low power mode to supply the heartbeat signals.

Ultralow-power sensor hubs

A system includes a frequency-locked loop (FLL) circuit, a sensor-hub circuit and a processor. The FLL circuit is used to generate a low-frequency clock. The sensor-hub circuit is coupled to a number of sensors and is configured to periodically poll the sensors during polling periods and to detect sensor activities. The processor is coupled to the sensor-hub circuit and can process sensor signals from one or more active sensors. The processor is off during polling periods and is turned on when a sensor activity is detected. The polling periods are based on the low-frequency clock generated by the FLL circuit.

MOTORIZED WINDOW TREATMENT

A motorized window treatment may provide a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment may include a covering material (e.g., a cellular shade fabric or a roller shade fabric), a drive assembly for raising and lowering the covering material, and a motor drive unit including a motor configured to drive the drive assembly to raise and lower the covering material. The motorized window treatment may comprise one or more battery packs configured to receive batteries for powering the motor drive unit. The batteries may be located out of view of a user of the motorized window treatment (e.g., in a headrail or in a battery compartment). The motorized window treatment may use various power-saving methods to lengthen the lifetime of the batteries, e.g., to reduce the motor speed to conserve additional battery power and extend the lifetime of the batteries.
