Sleep state estimation device and program product for providing a computer with a sleep state estimation function

An object of the present invention is to provide a sleep state estimation device capable of estimating a sleep state (deep sleep, light sleep) in real time with relative simplicity. Voltage variations resulting from human respiratory movement are measured for each given period to calculate from the measurement results positive voltage peak values and time intervals between adjacent peaks. The obtained peak values and peak intervals are used to calculate a mean peak interval value A, a coefficient of variation B based on dispersion of the peak intervals, and a coefficient of variation C based on the peak values. The sleep state in this period is estimated from the calculation results. More specifically, referring to FIG. 5, the sleep state is estimated as a “wakeful state” or a “hypnagogic state” by checking whether the mean value A is larger or smaller than a threshold a and whether the coefficient of variation C is larger or smaller than a threshold c (S105) whereas the sleep state is estimated as the “hypnagogic state”, “light sleep” or “deep sleep” by checking whether the coefficient of variation B is larger or smaller than a threshold b and whether the coefficient of variation C is larger or smaller than the threshold c (S109, S113, S116, S117).

Closed-loop hypnotic head cover based on brain electric wave monitoring

The invention provides a closed-loop hypnotic head cover based on brain electric wave monitoring. The closed-loop hypnotic head cover becomes a daily necessity (in the fields of agriculture, light industry and medical supplies). The closed-loop hypnotic head cover is simple in structure and powerful in function, and the bidirectional interaction between the head cover and a mobile phone is achieved. The head cover is micro and lightweight terminal equipment and is composed of a cover body and an equipment cabin. The cover body is a net-shaped 'cap'. The equipment cabin is a soft cabin body, a built-in brain electrical sensor can acquire delta, theta, alpha, beta and gamma brain electric waves in real time, and the brain electric wave occurrence time and duration in each sleeping stage are recorded; corresponding brain electrical music is played, and brain electric waves are guided from a waking state to a meditation direction, then from a meditation state to a light sleep direction, and finally from a light sleep state to a deep sleep direction; through tracing acquisition, vertical comparison and verification are conducted on brain electrical data, and according to quantitative data and qualitative analysis, an objective assessment is made; through an optimization algorithm, the volume of hypnotic music changes with the change of different brain electricity, the brain electrical music is firstly played to guide the brain electric waves, the brain electrical sensor and a three-dimensional acceleration sensor are used for double acquisition, and the hypnotic effect is analyzed in the aspects of the brain electricity and a body.

Air-conditioning control method, air-conditioning control system and air conditioner

The invention provides an air-conditioning control method, an air-conditioning control system and an air conditioner, wherein the air-conditioning control method comprises the following steps: the original value of the sign parameter of a user is detected to obtain the age phase information of the user, the air conditioner is controlled to enter a control mode corresponding to the age phase information according to the age phase information, the duration is reserved at an interval to detect the sign parameter of the user, and according to the change of the sign parameter of the user, the situation that whether the user is at the light sleep phase or the carosis phase is sequentially judged to control the air conditioner to be adjusted to the corresponding sleep mode. With adoption of the air-conditioning control method provided by the invention, the corresponding control mode can be voluntarily selected according to the sign parameter of the user to meet different demands for sleep temperature from users at different ages and the air conditioner is enabled to meet the diversified demands of different groups; in addition, according to the difference in the sign parameters of users at different phases, the sleep modes can be automatically adjusted to meet different demands for temperature from users at different sleep phases, and the control mode of the air conditioner is enabled to be more scientific.

Sleeping monitoring system and method thereof

InactiveCN104720753AImprove sleep qualityPreventing the Unforeseen Circumstances of DiseaseDiagnostic recording/measuringSensorsDiseaseOutput device
The invention provides a sleeping monitoring system. The sleeping monitoring system comprises a motion sensor, a monitoring device and an output device, wherein the motion sensor is connected with the monitoring device, and an output signal of the monitoring device is connected with the output device. A method of sleeping monitoring comprises the steps of A, presetting the threshold value of a triaxial gravitational acceleration sensor and a reference value during the change of a sleeping posture; B, performing monitoring on human body sleeping, and recording, analyzing and processing real-time accelerated speeds of the change of the sleeping posture and other motion conditions; C, outputting sleeping state information to the output device according to the real-time accelerated speeds of the change state of the sleeping posture and the other motion conditions. The sleeping monitoring system provides beneficial data support for improving the sleeping quality and preventing the unforeseen circumstance that diseases are caused by unhealthy sleeping habits. When a human body is at a light sleep state, an awakening signal is output to an awaking device. The method of the sleeping monitoring adopts the triaxial gravitational acceleration sensor to sense the sleeping posture and the change of the sleeping posture, the cost is low, and the operation is easy.

Air conditioner control method based on human body sleep state and air conditioner

The invention discloses an air conditioner control method based on the human body sleep state. The air conditioner control method comprises the following steps: an infrared sensor is utilized to detect and judge whether a user in an air-conditioned room is in the lying state; if yes, a radar sensor starts to sample the breathing state of the user within unit time and determine the sleep state of the user; when the user is in the non-sleep state, an air conditioner is controlled to run to enable the real-time human body comfort level of the user to be equal to the standard human body comfort level; when the user is in the light sleep state, the control mode controls the air conditioner to run to enable the real-time human body comfort level to be equal to a first corrected standard human body comfort level; and when the user is in the deep sleep state, the air conditioner is controlled to run to enable the real-time human body comfort level to be lower than the second corrected standard human body comfort level, wherein the second corrected standard human body comfort level, the first corrected standard human body comfort level and the standard human body comfort level are sequentially decreased. The invention further discloses the air conditioner. The air conditioner control method and the air conditioner have the advantage of high intelligent degree.
