摘要： 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. 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.

摘要： A utility cart includes an auxiliary swivel caster wheel assembly, a locking mechanism, and a trigger mechanism for causing the locking mechanism to releasably lock the auxiliary swivel caster wheel assembly. The auxiliary swivel caster wheel assembly is unlocked to enable the auxiliary swivel caster wheel to rotate about a vertical axis for improved maneuverability in small areas, and is locked to hold the auxiliary swivel caster wheel in a predetermined position for improved steering as the cart is moved from one location to another. The trigger mechanism is disposed on a steering handle to enable dynamic actuation of the locking mechanism while the cart is in motion.

摘要： A point of application workstation is disclosed and generally includes a base unit, a power unit, a support unit, a work surface and storage unit, a monitor assembly and a control unit. Extending upward from the base unit is the support unit which carries the work surface and storage unit, control unit and monitor assembly. The workstation may be stationary or mobile. The power unit is housed in the base unit. The work surface and storage unit may be configured with a variety of storage solutions for any of a number of work environments and tasks. The work surface and storage unit may house a computer that is integrated into the workstation. The control unit provides a measure of security for the workstation by allowing access to the workstation and control over its features only by authorized users.

摘要： A support system includes a support post and support means for adjustably supporting a member to the support post. The support means includes a locking mechanism movable between a first position for press-fitting the support means, directly or indirectly, against the support post and a second position for releasing the press-fitting. The locking mechanism has a surface that abuts the support post, or a wedge member associated with the support post, when in the first position thereby to effect the press-fitting and that is released from the support post when moved to the second position to release the press-fitting.

摘要： A lock assembly for use in an enclosed structure housing a locking bar having a plurality of locking fingers includes a lock arm mechanism having a lock arm and a lock arm mounting assembly for mounting the lock arm mechanism in the enclosed structure. The lock arm causes a rigid finger on the locking bar to be raised and lowered and in doing so raises and lowers the locking bar.

摘要： 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.
