Abstract: A multi-wheeled base for a mobile cart includes one or more swiveling, optionally locking, caster wheels and one or more non-swiveling traction wheels to improve the maneuverability of the cart by making it easier to steer and stop. The traction wheels may be manually-engaged traction wheels, which may be operated by a cam and lever. The traction wheels may also be automatically-engaged traction wheels operated by a motor and a threaded shaft, and activated by a motion-sensitive sensor or by an on/off electrical switch or button. The traction wheels are preferably in contact with the floor when the mobile cart is moving, and raised above the surface of the floor when the cart is stationary.

Abstract: A data processing application logging, recording, and reporting process and infrastructure. Compliance with regulatory directives such as HIPAA, internal organizational and corporate, personal information privacy, and other security policies can thus be enforced without the need to recode legacy application software. In one preferred embodiment, a core agent process provides “listener” functionality that captures user input events, such as keyboard and mouse interactions, between a user and a legacy application of interest. The agent obtains instructions for how to deal with such events, accessing information that describes the application's behavior as already captured by an application profiler tool. Keyboard and mouse data entry sequences, screen controls and fields of interest are tagged during application profiling process. This data is stored in application profile developed for each mode of a legacy application.
