KR20180015518A - Posture correction device with headphone using a horizontal sensor - Google Patents

Abstract

A device for neck massage and prevention of turtle neck syndrome having a shape capable of being put on the neck is able to sense horizontality with a low cost and simple horizontal sensor charging only 300 won, produce sounds with massage functions, and simply and efficiently corrects posture on the neck and the waist electronically. Through addition of various drowsiness prevention functions combined with smartphones and internet of things (IoT) technologies, the drowsiness prevention device can be a convenient wearable health care device. If the head falls down at an angle greater than a predetermined level, a cooling function can take effects to stop drowsiness by applying a slope sensor.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a posture correction device,

Horizontal sensor, posture correction

Until now, as a method of detecting drowsiness, the switch that senses the phenomenon of snoring when the drowsy is in, the basic drowsiness prevention device which made the mercury into the switch and the buzzer sounds through the electricity when the angle is more than a certain angle from the horizontal . However, not only the inconvenience of attaching this mercury sensor to the head but also the movement of the head even when not sleeping often causes the malfunction frequency to inconvenience the user, and it has begun to devise a more scientific and reasonable sensing method.

There are three types of technologies that have been introduced so far in relation to the drowsiness prevention device, and their characteristics and disadvantages are described below.

First, a commercialized drowsy earring sounds an alarm when the driver falls asleep. In other words, an alarm sounds even when the head is tilted, and the alarm does not ring if the driver does not bow his head (or leans on the driver's seat) (indirect measurement problem).

Second, an apparatus and method for preventing drowsiness based on an iridescent reflection image using a camera, an alarm sounds when a camera installed in front of a driver observes a pupil and the eyelid is wound for a long time or the pupil disappears from the camera. Such a device may malfunction due to strong scattered light, bowing or turning the head (sensor characteristics and arrangement problem), and moreover, the configuration is complicated and the installation cost is expensive (configuration problem).

Third, in the case of a device and method for preventing drowsiness of a vehicle (Patent No. 193924), drowsiness is sensed by a piezoelectric element and a lane detecting portion of a bumper disposed on a handlebar, and an alarm and a vibration sheet are operated to awaken a driver. However, depending on the position of the piezoelectric element, the pressure information is uncertain (sensor arrangement problem), the alarm sounds when the lane changes without losing sleep, and the alarm does not ring (indirect measurement problem). As can be seen from the above description, the above technologies can cause an alarm to be sound even in a non-sleeping state due to problems of sensor arrangement, indirect measurement, configuration and characteristics. Especially, the latter two are complicated in configuration and expensive. On the other hand, in the case where the pulse rate sensor is fixed to the umbilical vein of the wrist, the sensor can be accurately measured because it is in close contact with the umbilical vein of the wrist by a constant force. However, in the case of the grip strength measurement value, (Sensor characteristics and layout problems).

Observing that the surprise of the eyes is accelerated when the driver is sleepy, the drowsiness level detection system by visual monitoring is introduced. In general, the eye area tracking method detects an eye area in an input image transmitted using a front camera, measures the eye movement by a period of infrared absorption and reflection, Detect and sound an alarm or shock to get rid of drowsiness. However, this method is disadvantageous in that it is limited in use in a worksite or a classroom where classes are taken, since a video device or a fixed infrared emitter is necessary in the front. Therefore, the drowsiness detection method to be adopted in the present invention intends to improve the monitoring accuracy by a combination of the pulse rate measurement method and the gradient change gravity sensor which occurs when the drowsiness occurs while sleeping.

Generally, the pulse rate is almost constant when the blood pressure is normal. However, when the blood pressure is tired or sleepy, the pulse rate is lower than the normal pulse rate (hourly rate) and the blood pressure is lowered. In recent years, many researches have been made on the eyedropper recognition drowsiness prevention device. However, the inventor of the present invention has pointed out that the present invention can be easily installed and the portion where the pulse can be detected in the body part is widely distributed. In addition, when attaching any part of a car handle or body, it is possible to prevent the drowsiness in the state of the pre-drowsiness by analyzing a certain number of pulses as a pulse only by a difference in detection degree.

By allowing the user to maintain a posture that does not put the most stress on the spine when the user is sitting and working, it is possible not only to keep the user in the right posture, but also to prevent diseases such as a waist disk, The purpose of this paper is to provide a posture corrector.

When the liquid metal is out of the horizontal due to gravity, it senses the attitude disturbance through the current, and by combining this principle with the vibration motor in the form of headphone or necklace, the effect of stimulating the nape is obtained. Also, a small speaker makes a beep sound so that it can tell when the posture is disturbed.

It is a device for the posture correction of growing teenagers. It detects the attitude disturbance through the current when the liquid metal is out of the horizontal due to gravity inside. It combines this principle with the vibration motor in the form of headphone or necklace to stimulate the nape Effect.

This invention predicts each phase of the sleeping by detecting the pulse. It generates sound or vibration as a relatively weak warning until the second and third stages, but when the tilt sensor and pulse detection occur at the same time, It is equipped with a function to wake up drowsiness by cooling. In recent years, a lot of wearable smart watches, bands and glasses that are connected to Apple's, Sony's and Samsung's smart phones have been researched and the market is about to be released, and the detection function and operability of the drowsiness prevention device will be upgraded further. It is possible to make the function more advanced, smaller and lighter.

It combines this principle with the vibration motor in the form of headphone or necklace to stimulate the nape Effect. Also, a small speaker makes a beep sound so that it can tell when the posture is disturbed. There are many products that come out with vibration massage, but there is no horizontal sensor here, so it can be applied by cooling or weak electric stimulation which can give a slight stimulation to prevent sleepiness.
