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 user can then be aroused during a light phase of sleep by timing the dawn simulator to increase to sufficient brightness to arouse the user during a light stage of sleep that is proximate to a desired wake up time.

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.

Abstract of Disclosure Method and arrangement for operating a communication system for communication between a central station (10) and one or a plurality or remote objects (20 to 25), as well as such an object, wherein at least one object is operated in a battery saving mode in which it is switched alternatively between a wake period for conducting communication between the object and the central station and a sleep period in which communication is inactive. Each object is designated a predetermined first time (t0) and a time interval (Dt), wherein each object initiates the wake periods at times t0+n (Dt) with n=0, 1, 2, ... and wherein the time interval is longer than the wake period.

The invention discloses an electronic price tag, a gateway and an electronic price tag system, and relates to the technical field of electronic price tag networking, and the electronic price tag comprises a data dynamic sending module which is used for randomly selecting time in a preset time interval and sending broadcast information to the gateway; the wake-up time selection module is used for entering sleep to select the wake-up time in the next time interval when the feedback information of the gateway is not obtained; and the time calculation module is used for stopping sending the broadcast information when the feedback information is obtained, entering dormancy and calculating the time for sending the data updating request information by next wake-up according to the time zone parameter information. The gateway comprises a time zone configuration module which is used for configuring a time zone and sending time zone parameter information to the electronic price tag. The electronic price tag system comprises the electronic price tag and a gateway. According to the invention, the broadcast information is sent by segmenting the electronic price tags and randomly waking up the electronic price tags within the segmentation time, so that automatic and rapid networking of the plurality of electronic price tags and the gateway is realized, and the network collision probability is reduced.
