Blanket and pillow set

A circuit and method of analog data acquisition synchronization from an analog sensor in multiple channels associated with a USB hub. An analog to digital converter connected to the sensor that is part of a USB device has a time and phase corrected sampling clock that is referenced to a start-of-frame traffic signal with a preconfigured message indicating a time offset or delay seen upstream through a USB port. A plurality of similar devices are autonomously synchronized by the same message for multi-channel data acquisition by a locally generated trigger signal that allows a preset amount of delay set by the message. An accelerometer is a preferred sensor for such multi-channel data acquisition.
