TL;DR: In this paper, a sleep monitoring system consisting of a pressure sensor, a processor and an alarm is presented, where the pressure sensor is arranged in a mattress of a person under guardianship.
Abstract: The invention discloses a sleep monitoring system and a sleep monitoring method. The sleep monitoring system comprises a pressure sensor, a processor and an alarm, wherein the pressure sensor is arranged in a mattress of a person under guardianship, and when the person under guardianship moves in the bed, the pressure sensor is used for outputting different electrical signals according to different movements; further the processor is used for assessing the sleep of the person under guardianship according to electrical signals output by the pressure sensor and controlling the alarm to give out corresponding alerting signals according to assessment results. As the sleep monitoring system is used for monitoring the sleep state of the person under guardianship in a non-contact manner, the influence on the psychology of the person under guardianship is avoided, and the monitoring accuracy is increased.

TL;DR: A sleep evaluation device X includes: a sleep state determination part 1 for determining a person's sleep state in a sleep period from going to bed to leaving bed based on the person's biological information, a sleep section setting part 2 for dividing the sleep period into at least two sections; a sleep index setting part 3 for setting at least one sleep index for each section into which the sleep periods is divided by the sleep section-setting part 2; sleep index creation part 4 for creating each sleep index set by the SIS part 3 as discussed by the authors.
Abstract: PROBLEM TO BE SOLVED: To provide a sleep evaluation device capable of presenting appropriate sleep advice by accurately evaluating the quality of sleep by a simple method.SOLUTION: A sleep evaluation device X includes: a sleep state determination part 1 for determining a person's sleep state in a sleep period from going to bed to leaving bed based on the person's biological information; a sleep section setting part 2 for dividing the sleep period into at least two sections; a sleep index setting part 3 for setting at least one sleep index for each section into which the sleep period is divided by the sleep section setting part 2; a sleep index creation part 4 for creating each sleep index set by the sleep index setting part 3 based on the result of the determination by the sleep state determination part 1; a sleep evaluation value calculation part 61 for calculating a sleep evaluation value for each section using the sleep index created by the sleep index creation part 4; and a sleep evaluation part 7 for evaluating the person's sleep for each section based on the sleep evaluation value.

TL;DR: In this paper, a control circuitry determines whether the first sleep state indicates the user has fallen asleep, and the control circuitry generates for display the first media asset to enhance the user's sleep.
Abstract: Methods and systems for enhancing sleep of a user. In some aspects, control circuitry receives a first input relating to a first sleep state. The control circuitry determines whether the first sleep state indicates the user has fallen asleep. In response to determining the user has fallen asleep, the control circuitry determines a first media asset corresponding to the first sleep state. The control circuitry generates for display the first media asset to enhance the user's sleep. The control circuitry receives a second input relating to a second sleep state. The control circuitry determines whether the second sleep state indicates the user is ready to be awakened. In response to determining the user is ready to be awakened, the control circuitry determines a second media asset corresponding to the second sleep state. The control circuitry generates for display the second media asset to awaken the user.

TL;DR: In this paper, a sleep switch opens to interrupt current to the power supply converter after a first predetermined period expires, after which the sleep switch closes and then the current switch breaks after a ring-back signal informs a user that telephony service has been restored.
Abstract: Current to a relay causes a telephone to be connected to a SLIC Following LOOP, a sleep switch opens to interrupt current to the power supply converter after a first predetermined period expires If the telephone is on-hook, loss of current to the relay causes disconnection from the SLIC, but causes connection to a battery Current sensed from the battery through an off-hook hook switch generates a current signal The current signal closes a current switch, which is in parallel with the open sleep switch, thereby providing a current path to the converter The sleep switch then makes and then the current switch breaks After awakening, a ring-back signal informs a user that telephony service has been restored and a message may indicate that telephony service is being sought When the telephone is placed back on-hook, counting of a second predetermined period starts, after which the sleep switch opens again

TL;DR: In this paper , the authors investigate how various physiological signals recorded during sleep or wakefulness relate to objective measures of cognitive or physical performance and subjectively perceived sleep quality to inform conceptual understanding of the elusive, amorphous, and multi-dimensional construct of sleep quality.
