A turbo decoder system decodes L-length digital data consisting of a systematic code and 1and 2parity check codes, and includes a trellis controller obtaining the ratio of the bit-number Ep of the 1/2parity check code to the bit-number D of an original systematic code and generating, based on the code rate of the digital data, a trellis control output indicating a target decoding trellis, which is selected by a turbo decoder to perform decoding operations. A zero-patch module patches zeros into the systematic code, and patches, based on the value of Ep/D, one or more zeros into the 1/2parity check code so that parity check bits of the 1/2parity check code and the zero-bit(s) form a periodically depunctured parity check code.

A nursing system of the present invention can position where a person to be nursed through a sensor network widely deployed in an environment, instantaneously detect if the person to be nursed has an accident, and forward a message to inform a relative or medical staff. An autonomous robot will actively move beside the person to be nursed and transmit real-time images to a remote computer or PDA so that the relative or medical staff can swiftly ascertain the situation of the person to be nursed and the person to be nursed in case of emergency can be rescued as soon as possible.
