Abstract: A feedback-control wearable upper-limb electrical stimulation device includes a plurality of electrical stimulation electrodes (10), a plurality of electromyography signal sensors (20), an electrical stimulation output unit (30), an electromyography signal acquisition unit (35), an electromyography signal operation unit (40), and a control module (50). Each electrical stimulation electrode (10) is adhered to or fixed in contact with a human trunk and applies an electrical stimulation signal to the neuromuscular system of the human trunk. Each electromyography signal sensor (20) is adhered to or fixed in contact with the human trunk at a corresponding position of the neuromuscular system of the human trunk where each electrical stimulation electrode (10) is disposed in an adhered manner. The electrical stimulation output unit (30) is connected to each electrical stimulation electrode (10) and provides an electrical stimulation signal.

Abstract: A feedback-control wearable upper-limb electrical stimulation device comprises a plurality of electrical stimulation electrodes (10), a plurality of myoelectric signal sensing elements (20), an electrical stimulation output unit (30), a myoelectric signal retrieval unit (35), a myoelectric signal operation unit (40), and a control module (50). Each electrical stimulation electrode (10) is adhered to or fixed in contact with a human trunk and applies an electrical stimulation signal to the neuromuscular system of the human trunk. Each myoelectric signal sensing element (20) is adhered to or fixed in contact with the human trunk at a corresponding position of the neuromuscular system of the human trunk where each electrical stimulation electrode (10) is disposed in an adhered manner.

Abstract: A network information security zone joint defense system is provided, which monitors a network connection status through a network defense appliance. Once the network defense appliance detects a user computer in a network system triggering the conditions of a network zone joint defense, the network defense appliance immediately and automatically connects to a specified network switch, such that the network switch interrupts the network access service provided for the user computer, so as to effectively prevent virus or hacker from continuing spreading virus to the same or other subnet of the network, and further prevent the virus from starting a DDoS attack or paralyzing the network server, and thus greatly reducing the damages and losses to the network system.
