TL;DR: In this paper, the authors proposed a sleep method and apparatus for an intelligent terminal, which comprises the steps of judging whether screen turn-on time of the intelligent terminal reaches screen automatic sleep duration or not; when the screen turn on time of an intelligent device reaches the screen sleep duration, judging whether the intelligent device is in a non operation state or not, and automatically turning off a screen to enter a sleep mode.
Abstract: The invention is suitable for the field of intelligent terminals and provides a sleep method and apparatus for an intelligent terminal. The method comprises the steps of judging whether screen turn-on time of the intelligent terminal reaches screen automatic sleep duration or not; when the screen turn-on time of the intelligent terminal reaches the screen automatic sleep duration, judging whether the intelligent terminal is in a non operation state or not; and when the intelligent terminal is in the non operation state, automatically turning off a screen to enter a sleep mode. The step of judging whether the intelligent terminal is in the non operation state or not specially comprises the sub-steps of judging whether the intelligent terminal is in an unlocking state or not; when the intelligent terminal is in the unlocking state, detecting whether a bezel of the intelligent terminal bears a pressure or not; when the bezel of the intelligent terminal does not bear the pressure, judging that the intelligent terminal is in the non operation state; and when the bezel of the intelligent terminal bears the pressure, judging that the intelligent terminal is in an operation state, and keeping a screen turn-on state. According to embodiments of the invention, the availability of the intelligent terminal is improved.

TL;DR: In this article, the procedure for enabling a sleeping person to wake within a predetermined time (tz) when roused by a suitable signal is designed to minimise attendant stress by arranging the preset time to coincide with the naturally occurring repetitive phases of light sleep.
Abstract: The procedure for enabling a sleeping person to wake within a predetermined time (tz) when roused by a suitable signal is designed to minimise attendant stress by arranging the preset time (tz) to coincide with the naturally occurring repetitive phases of light sleep i.e. REM sleep-phasers (tREM). The individual's cyclic pattern of REM and non-REM sleep is established over a reference period using suitably recorded indicators e.g. eye movement, pulse, breathing etc. and the data is programmed into an armband or ear-clip pulse rate monitor. The preset waking time (tz) is always chosen to suit the pattern with any temporary alteration of the natural cycle effected by a brief interruption of sleep by signal during a non-REM phase. USE/ADVANTAGE - Assists waking experience to be as pleasant as possible. Alternation of normal cycle during non-REM i.e. deep-sleep phase is generally not noticed by sleeper.

TL;DR: The census enumeration of the population has been a necessity in order that the prevalence of disease, as determined by other methods, can be meaningfully related to the numbers at risk.
Abstract: arrangements for takingthe census the subject of the diseases of the living occupied our attention, and preparations were accordingly made for procuring returns of all those ptrsons who laboured under disease either at their homes or in public institutions upon the night of March 30, 1851."12a The purpose of the iniquirv was thus described on the Sick Returns (schedules) that were used: " The alleviation of human suffering arising from bodily infirmity is a work in which every member of the community should naturally feel an interest; and one important step in this direction is to ascertain the extent and character of the evils to be contended with; towards these most desirable objects. the Commissioners hope to assist by means of this Return."12b The results of this pioneer inquiry, published in a volume entitled Report on the Status of Disease, might not, by modern standards, be regarded as giving very sound evidence upon the prevalence of disease; nevertheless the inquiry was not without value, and was repeated at each census of Ireland until 1911. Cut of a total population of some 64 million persons, 104,000, or 1 in 6242, were returned as " labouring under disease" on the\chosen night; 9,000 of these in hospitals, asylums, and gao&s, 47,000 in workhouses, and 48,000 in their own homes. One-third of the sick were returned as suffering from an infectious disease, one-quarter from disease of the nervous system, and one-tenth from respiratory disease including consumption. Circulatory disease was infrequent, afflicting only 0.5% of those sick. Coronary disease, of course, was not mentioned, but the following passage in connexion with the 266 cases of heart disease (out of over 6 million persons) reported by people in their own homes contains matter for pondering upon: " As, however, a diagnosis of cardiac affection could not well be made except by professional persons, and as the peasantry of Ireland popularly term several other affections chiefly of dyspeptic character 'diseases of the heart,' from the distress experienced being, for the miost part, referred to the precordial region, we think it likely that the number returned as labouring under disease of the heartat their own homes is somewhat exaggerated."12c Apart from blindness, deaf-mutism, and mental impairment, no attempt has been made at the censuses of England and Wales to ascertain the prevalence of disease, but, as has been emphasized earlier, the census enumeration of the population has been a necessity in order that the prevalence of disease, as determined by other methods, can be meaningfully related to the numbers at risk. The census, however, is more than an enumeration of the people by sex, age, and occupation. It is a periodic social survey embracing every individual in the country, determining not only the number but also the condition of the people in relation to their social environment, their homes, and their families. As such it not only provides the means for recording the results of medical progress in the past but also points out some of the directions in which further efforts are needed to achieve still greater progress in the future.

TL;DR: In this article, a movable and wearable sleep analysis device is adopted in the sleep analysis method for conducting sleep analysis based on environment monitoring, which comprises a core processor, a three-axis gravity acceleration sensor, an environment monitoring module, a display module and a sleep monitoring module based on the body temperature and the heart rate.
Abstract: The invention relates to a sleep analysis method and device based on environment monitoring. The movable and wearable sleep analysis device is adopted in the sleep analysis method for conducting sleep analysis based on environment monitoring. The movable and wearable sleep analysis device comprises a core processor, a three-axis gravity acceleration sensor, an environment monitoring module, a display module and a sleep monitoring module based on the body temperature and the heart rate. The core processor monitors the human body sleep stage according to body temperature and heart rate information sent by the sleep monitoring module, judges the sleep quality of the human body, analyzes the influences caused by the change of environment parameters on the sleep quality according to environment parameter information sent by the environment monitoring module, finds the environment condition suitable for the sleep of a user most and improves the sleep quality of the user. The problems that an existing sleep monitoring device can not analyze the sleep quality according to the change of environment parameters or provide the optimal environment parameters affecting the sleep quality are solved.
