A device and a method for waking a user in a desired sleep state. The device may predict an occurrence when the user will be in the desired sleep state, such as light sleep, and wake the user during that predicted occurrence. In one embodiment, a user may set a wake-up time representing the latest possible time that the user would like to be awakened. The occurrence closest to the wake-up time when the user will be in light sleep may be predicted, thereby allowing the user to sleep as long as possible, while awakening in light sleep. To predict when the user will be in the desired sleep state, the user's sleep state may be monitored during the night or sleep experience and the monitored information may be used in predicting when the user will be in the desired sleep state.

A new protocol system and method is described that utilizes a Schedule Information Vector (SIV) protocol for saving power in wireless local area networks. The protocol includes an access point, one or more stations, and an SIV frame including an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. The access point originates and transmits the SIV frame protocol of the scheduled wake-up time to the stations. The SIV frame protocol of the wireless network is further operable to dynamically adjust the scheduled wake-up times of the stations, a sequence of the wake-up times, a periodic wake-up time, a plurality of wake-up times, and a duration of the wake-up times of the stations. These adjustments may be made based on network traffic, traffic buffering times, data priorities, data length, and data rates.

A user is aroused from sleep by applying a stimulus of light to simulate dawn. The device operates to monitor movements of a sleeping subject by the use of one or more motion sensors. The detected movements are used to identify the sleep cycle timings for the user.

The present invention relates to an improved countermeasure for circadian and sleep disruption as caused by a traditional alarm clock. It incorporates a lighting system at the alarm clock that, prior to the preset waking time, will emit a light that gradually increases in intensity as it changes the ultraviolet spectrum of light it emits, so as to simulate the rising sun. This will ease the waking process for many people, especially those prone to simple disruptions of their circadian regulation. It may also be set to operate in a reverse mode so as to simulate the setting sun thus helping stimulate melatonin production and easing one into sleep.

Use of the sleep cycle count as an input to the decision algorithm advantageously enables a user to more fully control and optimize his or her personal sleeping behavior.

In transmission of paging information from a mobile network to a terminal device (200), the terminal device applies a discontinuous reception cycle to enter a sleep mode. Further, the terminal device determines an advance wakeup time (AW) for leaving the sleep mode. The advance wakeup time (AW) is advanced by an advancement time interval (DeltaA) with respect to a start of an active time of the discontinuous reception cycle. At the determined advance wakeup time (AW), the terminal device leaves the sleep mode and starts monitoring the downlink control channel with respect to paging configuration information transmitted by the mobile network. The paging configuration information defines a paging occasion for transmission of the paging information. On the basis of the paging configuration information, the terminal device monitors the paging occasion to receive the paging information from the mobile network.

According to an aspect, a wireless station uses a low-frequency clock during sleep intervals and a high-frequency clock during awake intervals. Drift between the low-frequency clock and the high-frequency clock are corrected to enable aligning a wake time instant of the wireless receiver with start of beacon transmissions from an access point, and thereby to reduce power wastage. According to another aspect, errors between the clock of an access point and that of a wireless station are corrected. The wireless station computes an error between the clocks, and extrapolates the error for a sleep interval to compute a wake-up time instant. The correction and extrapolation are performed in every awake interval. Again, undesired power consumption in the wireless station is thereby reduced.
