Abstract: A cabinet assembly includes a cabinet body, a tiltable wire shelf, and a shelf mounting system. The cabinet body has a base, a top, and a pair of sides that extend between the base and the top to define an inner volume. The tiltable wire shelf is mounted in the inner volume of the cabinet body and includes a front bar, a rear bar, a pair of side bars, and a plurality of crossbars. The shelf mounting system supports the tiltable wire shelf on the cabinet body and comprises a pivot coupling between the cabinet body and the front or rear bar of the tiltable wire shelf, and a sliding coupling between the cabinet body and one of the side bars of the tiltable wire shelf. The couplings cooperate to provide tiltable adjustment of the tiltable wire shelf relative to the cabinet body over a range of angles.

Abstract: A mobile computer workstation is disclosed and generally includes a base assembly, a power supply, a column assembly, a tray assembly, a monitor support assembly and a tray controller. The power supply can be housed in the base assembly. The column assembly is linearly extensible and extends upward from the base assembly. The column assembly can carry the tray assembly and monitor support assembly. The workstation can be optionally configured with a variety of storage solutions for any of a number of work environments and tasks. The tray assembly can house a computer that is integrated into the workstation. The tray controller provides a measure of security for the workstation by allowing access to the workstation and control over its features only by authorized users.

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.

Abstract: 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.

Abstract: An emergency crash cart includes a sealing structure that enables multiple storage sections of the cart to be locked and sealed simultaneously. The locking structure enables one of the storage sections to be unlocked and unsealed without unlocking or unsealing the other storage sections. The locking structure also can be actuated to unlock and unseal all storage sections simultaneously for rapid access to the contents of all storage sections of the cart.
