Abstract: Methods and systems for estimating blood analyte conditions. In some methods, signal data may be received from a non-invasive blood monitor. The signal data may be used to train a model, which model may use a feature comprising at least two distinct electromagnetic radiation wavelengths, such as a Beer-Lambert inversion model. Following model training, signal data may be received from a non-invasive blood monitor using the at least two distinct electromagnetic radiation wavelengths. The trained model may then be used to estimate a blood analyte condition associated with the blood analyte, such as a concentration of the blood analyte.

Abstract: Apparatus for holding a fishing-hook while facilitating the threading of fishing-hooks. In an exemplary form, the invention includes a clam-shell housing, the housing having a pair of opposing first and second blocks, a pair of opposing first and second surfaces, with the first surface in the first block and the second opposing surface in the second block. The embodiment further includes at least one aperture formed at a periphery of at least one of the opposing surfaces and at least one hook-receiving channel to receive and fixedly engage the fishing hook, the channel being etched into the same opposing surface as the aperture and substantially shaped in form of the fishing-hook, with channel connected at one end to the aperture and extending thereof inwardly along the etched surface. In this way, a fishing-hook is firmly held by the housing, thus facilitating the threading of the hook.

Abstract: Apparatus and associated method for holding and restricting the movement of a fishing-hook while facilitating the threading of fishing-hooks. In an exemplary form, the invention includes a clam-shell housing for a fishing-hook, the housing having a pair of opposing first and second blocks, a pair of opposing first and second surfaces, with the first opposing surface in the first block and the second non-opposing surface in the second block. The embodiment further includes at least one aperture formed at a periphery of at least one of the opposing surfaces and at least one hook-receiving channel to receive and fixedly engage the fishing hook, the being channel etched into the same opposing surface as the aperture and substantially shaped in form of the fishing-hook, with channel connected at one end to said aperture and extending thereof inwardly along said etched surface. In this way, a fishing-hook is firmly held by the housing, thus minimizing movement and facilitating the threading of the hook.
