Streaming content using a data streaming device having limited power is described. A data streaming device receives streaming content from a network and provides the streaming content for display on a content display device. Data streaming device includes power supplies that receive power from the content display device. The power supplies use the power to operate components of data streaming device that process the streaming content. A measuring module measures the power provided to the data streaming device. When the power is insufficient, a controller generates an indication that there is insufficient power to operate the components of the data streaming device. The controller may also modify functionality of the components to operate using available power or disable a component of the data streaming device.

Users are enabled to readily use desired applications. A wireless communication device performs an inter-device wireless communication with another wireless communication device in accordance with the Wi-Fi (Wireless Fidelity) Direct specification. This wireless communication device includes a transmitting unit. This transmitting unit incorporates information about the role of the wireless communication device into an action frame specified in the IEEE (Institute of Electrical and Electronic Engineers) 802.11 specification, and then transmits the action frame.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support dynamic clock switching within a transmission time interval (TTI) to allow for more efficient and flexible processing within the TTI. In particular, a user equipment (UE) may be configured to use multiple clock speeds for processing signals within a TTI, and the UE may determine a clock speed to use for processing data within a TTI based on control information received from a base station. For example, the UE may determine an amount of time available for processing data based on the control information received from the base station, and the UE may adjust its clock speed to finish processing the data in the determined amount of time.

A motorized window treatment for controlling the amount of daylight entering a space through a window includes a covering material, a drive shaft, 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 to minimize motor usage and conserve battery life. 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, or in response to an infrared or radio-frequency remote control.

A timing method and a clock device are provided. The method includes: determining a timing point according to a timing duration of a clock device, where a clock period of the clock device is T, the timing duration is N times of a first time duration, and the first time duration is equal to Q.sub.2T, where Q.sub.2=Q.sub.1 or Q.sub.2=Q.sub.1 and Q.sub.1=C/T, N is a positive integer, Q.sub.1 is not an integer, and C is a constant (210); and performing one adjustment on timing time of the clock device each time P first time durations elapse, where an amount of time for each adjustment is one clock period T, P=1/|Q.sub.2Q.sub.1| (220). Based on this method, accurate timing can still be effectively implemented when a ratio of a constant C (for example, 1.25 ms) to a clock period is not an integer.

Disclosed is a closed-loop clock calibration method, comprising: performing clock calibration according to a calibration factor of an n.sup.th calibration period within the n.sup.th calibration period, and obtaining a calibration error of the n.sup.th calibration period; and according to the calibration error and calibration factor of the n.sup.th calibration period, obtaining a calibration factor of an (n+1).sup.th calibration period, n being a positive integer. Also disclosed are a terminal and a computer storage medium.

Example systems and methods are provided for maintaining a system clock during a sleep mode of a mobile communication device. An example system may include a high frequency clock circuit configured to generate a system clock, and a low frequency clock circuit configured to generate a sleep clock, where the sleep clock has a lower frequency than the system clock. The example system may further include a sleep system configured to deactivate the system clock in response to the mobile communication device entering sleep mode. The sleep system may include a sleep counter configured to use the sleep clock to maintain a sleep count for the deactivated system clock during the sleep mode, and a calibration unit configured to activate a calibration clock at periodic intervals during the sleep mode and utilize the calibration clock to calibrate a frequency of the sleep clock.

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 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.
