Abstract: Systems and methods for generating a personal profile and a recommendation based on the generated personal profile. The method includes generating a plurality of clusters, each cluster of the generated plurality of clusters including at least a set of variables for users included in the cluster, the set of variables related to at least one of gender, age, skin tone, acne marks, acne frequency, a lesion score, or a body distribution score, generating, for a new user, a profile, associating the generated profile into a cluster of the plurality of clusters, and generating, by a machine learning (ML) model, a recommendation for the user based on the associated cluster.

Abstract: An anterior rolling walker has a ground support frame, a vertical riser assembly, a torso support assembly and an actuator apparatus which allows a user to raise the torso support assembly from a first lowered position to a second raised position, and to anyone of a plurality of positions there between. The lift mechanism utilizes a single telescoping riser assembly which is positioned offset from the front of the walker, such that there is minimal structure to the front of the user, allowing the user to ambulate directly to (and make physical contact with) tables, desks, refrigerators, loved ones, and the like.

Abstract: A chain saw protector comprising a “U” shaped block of elastic material having a proximal base and first and second spaced apart mutually parallel legs, each having distal ends containing bores that are longitudinally aligned with each other where the bore in the second leg includes circumferential internal threads that engage a threaded shaft disposed in the bores, where the turning of the shaft brings the legs together for clamping a chain saw guide bar between the legs.
