Great Toe Dorsiflexion Detection
First Claim
1. A biosensor for detection of limb movement and collection of biosensor data comprising:
- a biosensor housing having a ring portion and a housing portion, the toe ring portion defining a passage way through which a toe, finger, or other appendage may be received; and
an electronics sensor package disposed within or onto the housing portion of the biosensor housing having a power source, a movement processor, an activator, a data memory device, and a communications interface for transmitting data, wherein the movement processor is powered by the power source responsive to the activator, wherein movement of an appendage received in the ring portion is detected and recorded into the data memory device by the movement processor, and wherein the records in the data memory device may be transmitted selectively via the communications interface.

Abstract
A limb movement biosensor for wearing upon a great toe or other appendage, the wearing upon the great toe being particularly useful for sensing dorsiflexion of the great toe as an indicator of contraction of a wearer'"'"'s tibialis anterior muscle. A particular configuration of one embodiment allows for extended, multi-night data collection of limb movements by allowing an embedded microcontroller to sleep until movement greater than a pre-determined magnitude is detected by an accelerometer, by recording into memory such detection, while avoiding recording of the actual magnitude value of the detected movement. According to another optional embodiment feature, a light sensor is configured to wake up the processor from a lower power state, such as when a user removes the device from a light-protected package.
