Method and device for starting sleep timer of terminal

Abstract: The embodiment of the invention provides a method and a device for starting a sleep timer of a terminal. The method comprises the following steps of: when the terminal is in a state where data are not transmitted, judging whether the terminal is used for executing real-time services, if so, setting the duration of the sleep timer of the terminal as first duration, and otherwise, setting the duration of the sleep timer of the terminal as second duration, wherein the first duration is greater than the second duration; and after the sleep timer of the terminal is set, starting the sleep timer. By the embodiment of the invention, the connection establishment time delay of the terminal of a user can be reduced, the calling time delay of voice services is reduced, and the experience of the user is improved.

Sleep Deprivation, Immune Suppression and SARS-CoV-2 Infection

Abstract: Sleep health and its adaptation to individual and environmental factors are crucial to promote physical and mental well-being across animal species. In recent years, increasing evidence has been reported regarding the relationship between sleep and the immune system and how sleep disturbances may perturb the delicate balance with severe repercussions on health outcomes. For instance, experimental sleep deprivation studies in vivo have reported several major detrimental effects on immune health, including induced failure of host defense in rats and increased risk for metabolic syndrome (MetS) and immune suppression in humans. In addition, two novel risk factors for dysregulated metabolic physiology have recently been identified: sleep disruption and circadian misalignment. In light of these recent findings about the interplay between sleep and the immune system, in this review, we focus on the relationship between sleep deprivation and immunity against viruses, with a special interest in SARS-CoV-2 infection.

System and method for transitioning a system comprising a microcontroller into a low power state in response to a first sleep type which is not recognized by part of the system and a second sleep type which is recognized by part of the system

Abstract: A computer system having an Advance Configuration and Power Interface-compliant, or ACPI, operating system performs certain machine specific tasks before going to a low power state. When the computer operating system indicates that entry into the low power state is desired, a microcontroller embedded in an input/output chip is alerted. Synchronization between the main processor of the computer system and the embedded microcontroller of the ACPI operating system is achieved, reducing the likelihood of system failure on the next boot operation. The embedded microcontroller then also causes the state of devices connected to the input/output chip to be saved. This helps the machine to go to a known state during the resume process.
