Release date: 2006-11-29 Hong Kong invents a smart hand strap to improve sleep apnea The Hong Kong Polytechnic University invented the smart hand strap to improve sleep apnea, winning the IENA Germany Nuremberg World Invention Exhibition Gold Award in Germany.
Vegetable Seeds are used in the production of vegetable seeds, divided into conventional and hybrid seeds.Vegetables that conventional types of vegetables to grow itself through natural laws of seeds, vegetables hybrid seeds (general hybrid F1 generation of hybrid) is by using different features of plants (male and female parent) for their pollination, change its characteristics.
First, many varieties and complex.In science and technology is the first productive force and science and technology oriented market sense, such as policy, scientific research institutions, experts and scholars engaged in the work of agricultural breeding have mushroomed, new achievements and new varieties are created.The resulting problems, a species and strains are many, character difference is small, removing impurity harder when breeding, varieties of authenticity and purity is difficult to guarantee;Second, in many scientific research units and experts and scholars of breeding race, south guo is inevitable the sham as the genuine, some traits instability, poor adaptability, or no market with a production value of species, strain, misleading, interfere with the normal order of seed production and operation.So for buying vegetable seeds, should be on the basis of reputation good place.Buy formal cultivated seeds.

This smart hand strap uses the principle of acupuncture treatment of Chinese medicine to help patients with sleep apnea to breathe, and the patient's sleep apnea index is reduced by 30%. The price of the new instrument is one-tenth of the current instrument, and the researcher said it is cost-effective.
Sleep apnea patients often stop breathing when they sleep, and the movement of the abdomen often changes, so the waist circumference keeps changing. This technique requires patients to wear a special belt or dress while sleeping, with a set of conductive smart textile materials and a signal processor that receives messages from conductive smart materials to monitor abnormal changes in the patient's waist circumference.
When the patient stops breathing for ten seconds and the smart textile material senses an abnormal change in the waist circumference, the signal processor will send a message to the smart hand strap. The smart hand strap is tied to the two poles, and the current is stimulated by the current on the wrist. The process lasts for eight seconds, and the acupuncture points are massaged to restore the breathing. Although current is used, the user does not feel an electric shock or pain.
Wang Guocheng, dean of the School of Medical and Social Sciences at the Hong Kong Polytechnic University, who is responsible for this invention, said that patients with sleep apnea usually use a ventilator to help with breathing during sleep, but they often wake up users and affect their sleep quality. He said: "Patients who sleep with oxygen masks will feel uncomfortable." Wang Guocheng said that the new technology can restore breathing and enjoy the dream without having to wake up the user, without surgery.
Wang Guocheng revealed that the whole research process lasted for three years. During the period, he went to the national college of Chinese medicine to view the literature. It was mentioned that several acupoints were related to breathing, which was the best effect to stimulate the missing points. At present, there are manufacturers to discuss cooperation in this invention, and we hope that it will be put into production in the second half of next year.
In addition, PolyU won the IENA Germany Nuremberg World Invention Exhibition Bronze Award with the intelligent warm clothing system. The system utilizes electronic temperature control and detection system, special nano-cloth and wireless data transmission and monitoring technology to carry out system thermal function engineering design, so that intelligent warm clothing can maintain the temperature input according to individual needs under heating conditions. From the lowest five degrees to the highest twenty-eight degrees, skiing keeps people warm even in the polar regions. Ultrasonic decalcification technology and material high-sensitivity magnetoelectric sensors also won the Bronze Award in the same event.
