Abstract: Systems and methods are provided to provide guidance to a user regarding management of a physiologic condition such as diabetes. The determination may be based upon a patient glucose concentration level. The glucose concentration level may be provided to a stored model to determine a state. The guidance may be determined based at least in part on the determined state.

Abstract: A breakaway device for use with the strap system of a hard hat. The breakaway device is coupled to a strap system of a hard hat, and the strap system is coupled to a hard hat outer shell. The breakaway device includes a housing and a releasable component mated to the housing. In specific embodiments, the breakaway device further includes a latch. The latch includes a catch. When the device is configured in an unlatched position, the catch does not interfere with the removal of the releasable component from the housing. When the device is configured in a latched position, the catch does interfere with the removal of the releasable component from the housing, increasing the magnitude of force required to release the releasable component from the housing. In specific embodiments, both configurations are achieved with a single device. In other specific embodiments, the configurations are achieved through separate devices.
