Patent ID: 8810356

Claim:
A data buffer apparatus with wireless transmission for coupling to a health monitor by a UART interface, including: a UART interface module, coupled to the health monitor with the UART interface and receiving at least a signal data that are continuously measured by the health monitor; a FIFO memory module, coupled to the UART interface module for storing the signal data; a wireless transmission module, used to establish a wireless connection, for transmitting the signal data to a reception unit through a wireless method; a battery module to provide power to the data buffer apparatus; and a microprocessor module, coupled to the FIFO memory module and the wireless transmission module, only processes data transmission and power consumption of the battery module; wherein, when the FIFO memory module is stored with the signal data, the microprocessor module controls the wireless transmission module to attempt to establish the wireless connection; if the wireless connection is established successfully, the signal data sent in first to be processed is sent out first to the reception unit through the wireless connection from the FIFO memory module; if the wireless connection is not successfully established, the microprocessor module will attempt to establish the wireless connection again after a period of time, the signal data is buffered in the FIFO memory module; wherein a first level of power is used when the wireless connection is successful and a second lower level of power is used when the wireless connection is not successful.
