Description
BACKGROUND OF THE
Most people often take a position to sit with their legs crossed, even though the time is different, but if the legs are sitting for a long period of time, they have a negative effect on the human body.
In particular, when one leg is raised close to the knee of the other leg and taken for a long time, blood pressure rises and in severe cases it may cause temporary muscle paralysis due to vascular injury or nerve damage. Especially in males, blood circulation is not smooth and sperm count may decrease.
A device has been developed to sense whether the neck or waist position is not shifted to the left or right and maintains a straight line, but it can not detect the posture in which the leg is twisted.
When a person takes a sitting position in which the legs are twisted, he or she unconsciously maintains the posture, and therefore, most of the time, when the human body is caused to suffer pain, it is recognized whether or not it is in a posture in which the leg is twisted.
Therefore, there is a demand for a device capable of detecting a moment when the legs are twisted and sit.

According to another embodiment of the present invention, there is provided a magnetic resonance imaging apparatus comprising: a first sensor unit attached around a knee of a leg of a user and transmitting electromagnetic induction energy through a first coil; A second coil attached to the back of the knee of the other leg of the user, receiving the induced energy of the first coil through the second coil, vibrating the built-in vibrator using the received energy, A second sensor unit for transmitting an energy magnitude through a wireless communication scheme; And a portable terminal receiving and displaying the vibration frequency, the vibration time, and the received energy magnitude from the second sensor unit in a wireless communication manner.
The first sensor unit may include: the first coil formed in a circular shape; And a battery disposed inside the first coil and supplying power to the first coil.
The second sensor unit may include: the second coil formed in a circular shape; A vibrating part disposed inside the second coil and vibrating in a vibration pattern set using charged electric power; And a controller for detecting the number of vibrations and the vibration time of the vibrator, and the energy magnitude received by the second coil, and transmitting the detected magnitude of energy to the second coil through a wireless communication scheme.
In addition, the portable terminal adjusts the size of the alarm sound according to the number of times of vibration and the vibration time, and increases the size of the alarm sound as the number of times of vibration and the vibration time during the set period accumulate. do.
The leg position detecting device and the leg position detecting system according to the embodiment of the present invention can promptly inform the user of the vibration and the beep sound when the user unconsciously takes a sitting position in which the legs are twisted, . Therefore, it is possible to prevent blood pressure rise, vascular damage and muscle paralysis, which may occur due to posture in which the legs are twisted.
In addition, the user can confirm how often he or she takes a long leg-twisting posture through the vibration frequency and the vibration time displayed on the portable terminal, thereby helping the posture correction.

The leg position detecting device and the leg position detecting system according to the embodiment of the present invention can promptly inform the user of the vibration and the beep sound when the person unconsciously takes a posture in which the legs are twisted sideways, . Therefore, it is possible to prevent blood pressure rise, vascular damage and muscle paralysis, which may occur due to posture in which the legs are twisted.
In addition, the user can confirm how often he or she takes a long leg-twisting posture through the vibration frequency and the vibration time displayed on the portable terminal, thereby helping the posture correction.
In addition, since energy is consumed only when the first sensor unit and the second sensor unit are close to each other, the power consumption of the battery is reduced and the usable time is increased.
Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the embodiments described above are to be considered in all respects only as illustrative and not restrictive.
