A control method includes acquiring time information including a wake-up set time; acquiring a sleep state of a sleeper who is stimulated by a stimulation device; determining a change of the sleep state; causing the stimulation device to start increasing a stimulus which urges the sleeper to awake at a control start time as time before the wake-up set time by a predetermined time period; and controlling a change amount of the stimulus based on the change of the sleep state with the stimulus.

A method for an alarm silencing or suppression routine following activation of a wake-up alarm on an electronic device (42). The method comprises, following the alarm activation, monitoring (14) light levels at a light sensor (44) of the device and automatically silencing (20) or otherwise suppressing the alarm signal responsive to sensing (16) a light level at the sensor above a pre-defined threshold. Following alarm signal suppression, a further confirmatory monitoring period follows in which light levels at the sensor continue to be monitored (22). If they fall to below a further predefined threshold (26), or below the original silencing threshold, the alarm signal is reactivated (28). This ensures that a user has not returned to a darkened environment a short space of time after alarm silencing, which might lead to the user falling back to sleep.

A system for determining relevant information based on user interactions may include a processor configured to receive data and associated relevance information from a data source and a set of signals describing a current environment of a user or historical user behavior information in which the data source being local to a computing device. The processor may be further configured to provide, using a machine learning model, a relevance score for each of multiple data items based at least in part on the received relevance information and the set of signals. The processor may be further configured to sort the data items based on a ranking of each relevance score for each data item. The processor may be further configured to provide, as output, the multiple data items based at least in part on the ranking.

A multi-function clock is provided in which a clock face is configured to exhibit a first mode in association with a first clock function and a second mode in association with a second clock function. A first illumination feature is then configured to operate in association with at least the first mode and a second illumination feature is configured to operate in association with at least the second mode.

An apparatus control device includes a processor that acquires a stimulus acting on an apparatus from an outside, and sets an action time based on the acquired stimulus data, the action time being related to a behavior that a user of the apparatus habitually performs, the action time being a time at which the apparatus acts.

Techniques are disclosed for facilitating disabling an alarm in response to particular types of activity-indicative data. More specifically, activity-indicative data (e.g., sensor data or input(s) can be detected prior to a preset alarm time. Upon determining, based on the activity-indicative data, that a wakefulness condition is satisfied (e.g., that the activity-indicative data corresponds to one or more predefined characteristics), a disablement query can be displayed that includes an option to disable the alarm. In response to detecting a selection of the option, the alarm can be disabled such that the alarm stimuli is not to be presented at the preset alarm time.

A pulse wave signal is registered and an occurrence of human limb movements detected during sleep using a pulse wave sensor and an accelerometer. The values of RR intervals and respiratory rate are measured at preset time intervals Δt.sub.i based on pulse wave signal. Mean P.sub.1, minimal P.sub.2, and maximal P.sub.3 values of RR intervals, the standard deviation of RR intervals P.sub.4, average respiratory rate P.sub.5 and average number of limb movements P.sub.6 are determined based on the above measured values. Function value F(Δt.sub.i) is determined thereafter as:
F(Δt.sub.i)=−K.sub.1P.sub.1−K.sub.2P.sub.2−K.sub.3P.sub.3+K.sub.4P.sub.4+K.sub.5P.sub.5+K.sub.6P.sub.6,
where K.sub.1-K.sub.6 are weight coefficients characterizing the contribution of the corresponding parameter to function value F(Δt.sub.i); whereat the onset and termination of sleep phase favorable to awakening is determined by increments of function F(Δt.sub.i).

Upon ending or snoozing an alarm, an alarm clock module automatically engages media controlling devices to accomplish selected tasks. Examples of selected tasks include getting political or financial news, receiving a weather forecast or current traffic conditions, viewing or listen to entertainment, and accessing a planner or a calendar. In other words, the alarm clock module allows users to personalize what content the user would like to access or play while waking up. In use, the user has the ability to skip or adjust the order in which content is accessed or played. The alarm clock module differs from known media controlling devices which interface with virtual assistants because the primary input for the alarm clock module involves turning off or snoozing the alarm.

An electronic device configures the electronic device to operate in a first mode, when the current time is with a first scheduled sleep time period, and user input selecting an affordance using a first input mechanism is disabled in the first mode. While in the first mode, detecting first user input. The electronic device transitions the electronic device into a second mode different from the first mode if the first user input meets predefined criteria, and remains in the first mode and forgoes transitioning to the second mode if the first user input does not meet the predefined criteria.
