Abstract: Articles made of shape memory alloys having improved fatigue performance and to methods of treating articles formed from shape memory alloy materials by pre-straining the articles (or desired portions of the articles) in a controlled manner so that the resultant articles exhibit improved fatigue performance. The shape memory articles are preferably medical devices, more preferably implantable medical devices. They are most preferably devices of nitinol shape memory alloy, most particularly that is superelastic at normal body temperature. The pre-straining method of the present invention as performed on such articles includes the controlled introduction of non-recoverable tensile strains greater than about 0.20% at the surface of a desired portion of a shape memory alloy article. Controlled pre-straining operations are performed on the shape-set nitinol metal to achieve non-recoverable tensile strain greater than about 0.20% at or near the surface of selected regions in the nitinol metal article.

Controlled pre-straining operations are performed on the shape-set nitinol metal to achieve non-recoverable tensile strain greater than about 0.20% at or near the surface of selected regions in the nitinol metal article. The pre-straining operations result in a significant increase in fatigue life of the selectively treated regions and an overall improvement in the fatigue performance of the device.

Abstract: An alternator comprises a regulator configured to control the electric current to a field coil. The regulator includes a field driver circuit, the field driver circuit configured to deliver the electric current to the field coil at a switching frequency. The regulator further includes a controller configured to vary the switching frequency of the field driver circuit between a plurality of different switching frequencies. The alternator further comprises a sensor configured to detect a predetermined alternator condition, and the controller is configured to adjust the switching frequency of the field driver circuit in response to the sensed predetermined condition such as, for example, a rotor speed, a pulse width from the field driver circuit, an efficiency of the alternator, a temperature within the alternator, a temperature outside of the alternator, or magnetic noise of the alternator.

Abstract: A wall-mounted shelving system includes a track and a bracket engagable with the track. The bracket has a collar for supporting a shelf-carrying pilaster and an engaging element protruding from the collar that includes a floor and an arm projecting upwardly from the floor to define an elbow. The track is adapted to be mounted horizontally on a wall and includes a downwardly open channel at its top and an outwardly projecting ledge at its bottom. The upper extreme of the engaging element arm is received in the channel of the track while the elbow can be supported to rest on the ledge. A pilaster is adapted to then be supported in the collar through an intermediate wedge member, and shelves and other objects can be supported on the pilaster.
