Environmental temperature controlling apparatus

Abstract: PROBLEM TO BE SOLVED: To efficiently gain a sound sleep, namely, a comfortable awakening and a deep sleep by controlling an environmental temperature to match the biological sleep rhythm. SOLUTION: An environmental temperature controlling apparatus 1 includes a depth of sleep measuring means 41 and a temperature controlling means 51. The depth of sleep measuring means 41 has the function of detecting a starting point of sleep T 0 of a human body 9 and the function of measuring the depth of sleep of the human body 9 after the start of sleep and executes the detection of the starting point of sleep T 0 and the measurement of the depth of sleep after the start of sleep. The starting point of sleep T 0 and the depth of sleep are given to the temperature controlling means 51. The temperature controlling means 51 controls the environmental temperature on the basis of a cycle of the depth of sleep by decreasing the environmental temperature monotonously for at least a prescribed period from the starting point of sleep T 0 . The prescribed period is an interval between the starting point of sleep T 0 and the time when the depth of sleep reaches the second extreme value out of the extreme values showing the deep sleep.

Apparatus, system and method for thermoregulation

Abstract: PROBLEM TO BE SOLVED: To provide a good sleep by cooling a local part of a human body such as a head part without disturbing falling-asleep. SOLUTION: The subject thermoregulation apparatus is provided with a cooling/warming part 1, a temperature sensor 2 and a falling-asleep sensor 3. The temperature sensor 2 detects the temperature T of the head part, or the local part of a human body. The falling-asleep sensor 3 is provided with a body motion sensor 31 and a determination part 32, detects a time point of falling asleep and transmits it to a control part 11. Practically, the body motion sensor 31 detects the body motion of the human body to transmit it to the determination part 32. The determination part 32 finds the time t0 of falling asleep based on the body motion detected by the body motion sensor 31. The cooling/warming part 1 is provided with the control part 11 and a temperature regulation part 12. The control part 11 allows the temperature regulation part 12 to send air 100 regulated to a temperature lower than the temperature T of the head part from the time of falling asleep based on the temperature T of the head part as a local part of the human body detected by the temperature sensor 2. This constitution can cool the head part from the time of falling asleep. COPYRIGHT: (C)2006,JPO&NCIPI

Sleep controlling method and sleep controlling apparatus

Abstract: PROBLEM TO BE SOLVED: To regulate biorhythm by reducing an inhibition of a good sleep. SOLUTION: A sleep controlling method includes steps 11-15. In the step 11, a sleep is facilitated to make a starting point of the sleep earlier. In the step 12, an environmental temperature is reduced for a prescribed period after the starting of the sleep. In the step 13, the environmental temperature is maintained at the lowest value after the environmental temperature reaches the lowest value by the control in the step 12. In the step 14, an environment around a person before awakening is controlled. The step 14 includes a step 141 for increasing the environmental temperature, for example, monotonously increased for a prescribed period before an expected time of the awakening and a step 142 for facilitating the awakening. In the step 15, sleepiness after the awakening is reduced by applying light with stimulative brightness, color and temperature on a person. COPYRIGHT: (C)2006,JPO&NCIPI

Air-conditioning control system

Abstract: In order to provide a suitable environment corresponding to the stress state of room occupants and to the room occupants' purpose of use of the space, a deriving unit (27a) derives multiple heart rate-related parameters of the room occupants (E) on the basis of movement of the room occupants (E), and a determination unit (27b) determines the current stress state of the room occupants (E) on the basis of the heart rate-related parameters. A touch panel (41) receives the purpose for which the room occupants (E) are using the air-conditioned space (S). In response to the received purpose and the heart rate-related parameters, a device control-side CPU (48) selects a heart rate-related parameter that should be changed and controls operation of the air-conditioner (A) such that the selected heart rate-related parameter changes.

Sleep control device and control method therefor

Abstract: A drowsiness level detection section (6) detects a drowsiness level of an individual person. A sleep depth level control section (11) controls the sleep depth of the individual person based on the detected drowsiness level. The sleep depth level control section executes a first sleep control (4, s7), in which the sleep depth level of the individual person is maintained at a predetermined sleep depth level below a maximum sleep depth level (4, s6), if the detected drowsiness level is equal to or below a predetermined threshold.

Apparatus and method for controlling sleep mode of airconditioner

Abstract: An air-conditioner and a method for controlling the same are disclosed. The apparatus and method for controlling the sleep mode of the air-conditioner provides an optimum air-conditioning effect suitable for individual sleep stages in consideration of temperature characteristics of the sleep stages of a sleeping human being, such that it can provide the sleeping human being with an optimum sleep mode. The apparatus includes a room temperature sensor for detecting a room temperature; and a controller for controlling the sleep mode when the sleep mode begins, such that it executes a sleep-entrance stage for a rapid cooling mode during which the room temperature is quickly reduced to a first temperature less than a setup temperature, executes a deep-sleep stage for gradually increasing the room temperature to a second temperature higher than the setup temperature, and executes a wake-up stage for increasing the room temperature to a third temperature higher than the second temperature.
