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.

A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.

A wireless device, a network node and methods therein are provided for paging in a wireless communication network. The method in the wireless device comprises determining a paging window for receiving at least part of a paging transmission. The method further comprises receiving at least one paging synchronization signal, PaSS, comprised in the paging transmission, in said paging window; and further receiving at least one paging message comprised in the paging transmission, based on the received at least one PaSS.

A power management approach for a mobile device includes comparing a battery provided power supply voltage to a reference voltage in order to generate an alarm signal. In response to the alarm signal the frequency of an operating clock applied to a system-on-chip is changed.

Methods, systems, computer-readable media, and apparatuses for UE positioning are described. In some embodiments, a UE is configured to transmit a reference signal to a network resource for performing measurements on the reference signal and deriving the position of the UE. The timing of the reference signal is tracked at a particular precision. The precision is based on a timing accuracy that the UE can support from different timing accuracies. The different timing accuracies may be supported, each of which may have a different set of timing error limits. For example, for an angular-based positioning of the UE, a low timing accuracy may be supported. In comparison, for a timing-based positioning method, a high timing accuracy may be supported.

A method for communicating between a first radio frequency communications device including a first local oscillator and a second radio frequency communications device including a second local oscillator includes generating phase values based on samples of a received signal. Each of the phase values indicates an instantaneous phase of the received signal. The method includes unwrapping the phase values to generate unwrapped phase values. The method includes generating frequency offset estimates based on the unwrapped phase values. The method includes generating an average frequency offset estimate based on the unwrapped phase values. The method includes wrapping the average frequency offset estimate to generate a residual frequency offset estimate. The method includes adjusting the first local oscillator based on the residual frequency offset estimate, thereby reducing a frequency offset between the first local oscillator and the second local oscillator.
