Abstract

A wireless data acquisition system includes a data acquisition unit including a data sensor; a first wireless data link and a second wireless timing link with predicable or low latency. Stimulus and time markers come from a trigger generator. Data signals from the data sensor are transmitted across the wireless data link and timing information of the data acquisition unit is transmitted across the wireless timing link. A receiving host receives the transmitted data and timing information for logging and/or processing.

Claims

1. A wireless data acquisition system comprising:

a data acquisition unit including a data sensor;

a wireless data link; and

a wireless timing link with predicable or low latency;

wherein data signals from the data sensor are transmitted across the wireless data link and timing information of the data acquisition unit is transmitted across the wireless timing link.

2. A wireless data acquisition system according to claim 1, wherein a time marker is transmitted across the wireless timing link from a trigger source to the wireless data acquisition unit.

3. A wireless data acquisition system according to claim 2, wherein the time markers are combined with the signals from the sensor on the data acquisition unit and transmitted to a receiver across the wireless data link.

4. A wireless data acquisition system according to claim 1, wherein a time marker is transmitted from said wireless data acquisition unit to a receiver across said wireless timing link.

5. A wireless data acquisition system according to claim 1, wherein said wireless timing link comprises an infrared transceiver.

6. A wireless data acquisition system according to claim 1, wherein said wireless timing link comprises a radio frequency transceiver.

7. A wireless data acquisition system according to claim 1, wherein said wireless data link comprises a radio frequency transceiver.

8. A wireless data acquisition system according to claim 1, wherein the sensor is adapted for sensing physiological signals.
