Abstract: Computer implemented methods and systems are provided that comprise, under control of one or more processors of a medical device, where the one or more processors are configured with specific executable instructions. The methods and systems include sensing circuitry configured to define a sensing channel to collect biological signals, memory configured to store program instructions, a processor configured to implement the program instructions to at least one of analyze the biological signals, manage storage of the biological signals or deliver a therapy, and communication circuitry configured to wirelessly communicate with at least one other implantable or external device, the communication circuitry configured to transition between a sleep state, a partial awake state and a fully awake state.

Abstract: The present invention relates to a composition, for freeze-dry protecting extracellular vesicles, capable of preserving the function and characteristics of extracellular vesicles, and an extracellular vesicle freeze-drying method using same. Trehalose and sucrose of the present invention are added to an extracellular vesicle freeze-drying process to solve the problems of crystal growth and redissolution capacity degradation, which are problems in an existing freeze-dry protective agent, and also maintain the unique marker, functional factor expressions and therapeutic effects of the extracellular vesicles, and thus may be variously utilized for producing various therapeutic agents using extracellular vesicles.

Abstract: A faucet includes an outlet pipe and a switch member. The switch member is fitted on the outlet pipe near a water outlet and provided thereon with a pull handle able to be pushed to turn around. The push handle can be pushed to turn on or turn off the switch member on the faucet and can also be washed clean by water flowing down out of the outlet pipe, able to prevent bacteria from spreading and having great practicability.
