Abstract: A treadmill includes a frame having a front end and a rear end, substantially opposite the front end; a front shaft assembly coupled to the frame proximate the front end of the frame; a rear shaft assembly coupled to the frame proximate the rear end of the frame; a running belt disposed about the front and rear shaft assemblies; and a bumper coupled to the frame proximate the running belt such that the bumper is disposed between the running belt and the frame. The bumper includes a partially rounded surface and a substantially flat surface. In use, the partially rounded surface and the substantially flat surface of the bumper are configured to selectively engage and restrict movement of the running belt towards at least a portion of the frame.

Abstract: Example methods and apparatus for communicatively coupling internal components and accessories appliances, and appliances with external components and accessories are disclosed herein. A disclosed example method of operating a domestic appliance having at least one of an internal communications network and/or an external communications network among at least two components includes identifying the components, communicating the capabilities of each identified component, communicating the status of each identified component, providing a command interface for operating the components, facilitating communication between the components, and operating the appliance using the command interface and the facilitated communication.

Abstract: A network control system for an appliance has a software operating layer that is responsive to a plurality of appliance function calls. A physical user interface on the appliance is capable of generating directly some of the appliance function calls. A virtual user interface connected remotely over the network is also configured to invoke some of the appliance function calls. But the virtual user interface can further invoke one or more of the function calls that the physical user interface cannot generate directly.

Abstract: A method and apparatus for sequentially operating a refrigeration system with multiple evaporators is provided in which only one evaporator is operated at a time and is run until a set of fuzzy logic rules determines that one of the other evaporators should be operated or that the operation of the evaporators should be terminated.
