Abstract: The present invention provides an undercooling solidification method for preparing an amorphous or nanocrystalline soft magnetic alloy with high Fe content and the applicable amorphous or nanocrystalline alloy composition. The undercooling solidification is realized by glass purification combined with cyclical superheating or electromagnetic levitation melting. An undercooling solidification alloy is prepared into amorphous strips or powders through rapid quenching or atomization of melt, and can be prepared into a nanocrystalline alloy through heat treatment. The chemical formula of the applicable amorphous or nanocrystalline alloy is FeSiBM, wherein M is one or more of P, C, Nb, Mo, Zr, Hf, Mo, Y, Cu and Co. The amorphous or nanocrystalline alloy prepared by undercooling non-equilibrium solidification has the characteristics of high amorphous forming ability, high saturation magnetization and low coercive force.

Abstract: Techniques and apparatuses are described that implement a hearable with on-head detection using a single optical sensor. The hearable determines on-head detection based on a distance measured by the single optical sensor being less than a distance limit associated with on-head detection. A shape of the hearable's housing causes the hearable to have at least one orientation while at static equilibrium on a flat surface. This orientation causes the flat surface to be within the field-of-view of the optical sensor and causes a distance between the flat surface and the optical sensor to be greater than the distance limit associated with on-head detection. In this way, false positives associated with on-head detection can be mitigated without adding additional sensors (e.g., another infrared sensor, another proximity sensor, or a motion sensor) and without utilizing more complex optical sensors that determine additional information about the object, such as material composition.
