Abstract: A method of fabricating a curvilinear magnet includes forming at least one slot in a material billet. The slotted material billet is inserted into a mold having a curvilinear pocket. The mold is closed around the slotted material billet such that the slotted material billet conforms to the curvilinear pocket and forms a curvilinear billet. The curvilinear billet is arranged in a structure. The curvilinear billet arranged in the structure is then magnetized.

Abstract: Methods and systems for receiving, by a destination device at which a securement-monitoring application is operating, from a securement sensor device, a securement-condition communication indicating a condition of a securement remote to the destination device. Operations also include determining, by the destination device using the securement-monitoring application, an action to take responsive to the securement-condition communication, such as notifying a user of an undesired condition at the securement. The operations further include initiating the action determined.

Abstract: A system implemented at a user structure, to monitor a tracked object using a three-body arrangement including the user, a tracked object, and a controlling apparatus. The system has a data storage device including user-presence module code causing a processor to determine, based on wireless sensing, whether the user has entered a first space having a boundary external to the user structure, or has left the space. Object-presence module code causes the processor to determine, based on tracked-object-presence data, whether the tracked object is within a second space. And the storage device includes alert-module code to, in response to determining that, depending on the embodiment, (i) the user entered or exited the first space and (ii) the tracked object is or is not present within the second space, initiate provision of a system-user alert communication to indicate that the tracked object is not present within the second sensed space.
