Abstract: The contemplated modular jewelry organizer has a base and fixed segment that one or many modular segments may be connected to. The modular segments may be connected to each other to create longer segments. The connection may be facilitated by magnets. The modular segments may be separated from each other and from the fixed segment by retainment rings which prevent jewelry placed on one segment from moving to another segment.

Abstract: A body heat recovery device includes: a face mask, an inlet tube connected to a first portion of said face mask, an outlet tube connected to a second portion of the face mask; the inlet tube has a filter attached to an end of said inlet tube opposite an end of said inlet tube connected to the face mask to filter debris, dirt, etc., to protect the user.

Abstract: Rotational hardstop assemblies that provide greater than 360 degrees of non-continuous rotation for rotating mechanisms are provided. In certain embodiments, an assembly is used to provide 630 or more degrees of rotation for the shoulder axis of a robot, such as a wafer transfer robot. The rotational hardstop assemblies include opposing magnets as springs. According to various embodiments, the opposing magnets provide non-contact engagement and produce no contact noise nor have any wear over time. The rotational hardstop assemblies provide the ability to location from either direction of rotation of a robot cylindrical coordinate system.
