A medical examination chair kit includes a group of sensors including electrodes in finger-tip sensors, various other types of sensors incorporated in covers attachable or placeable on a chair and load cells on an adjustable grid supporting the chair, all of which provide data which is partially processed in a transmission pocket mounted on the chair. The method for acquiring the monitoring data includes: receiving registrations of the agent and a gathering device by the task distribution server; receiving, by the task distribution server, an acquiring instruction sent by the gathering device; and sending, by the task distribution server, the acquiring instruction to the agent to instruct the agent to acquire the monitoring data. A primary seam binds the outer portion and the inner portion to the material sheet at the midline proximate the outer portion edge and inner portion edge. A judgment operation belongs to the preset operation. The modification module includes an addressing module, for mapping a new, simulated network address to a network packet and a propagation module, for modifying a propagation characteristic of the network connection.
