A method and apparatus for setting or modifying a programmable operating parameter associated with a power driven wheelchair is provided. In one embodiment, the method includes: a) operating a user interface device associated with a power driven wheelchair in a programming mode, b) selecting a programmable operating parameter associated with operation of the power driven wheelchair using the user interface device, c) selecting a value for the programmable operating parameter using the user interface device, and d) saving the selected value for the programmable operating parameter in a portion of a storage device associated with the power driven wheelchair using the user interface device. A method and apparatus for selecting one or more programmable parameter sets from a portable storage medium and saving the selected sets to a local storage device associated with a power driven wheelchair and vice versa is also provided.

By programming position parameters corresponding to user support surfaces of a power driven wheelchair, movement of the user support surfaces is automated. The user support surfaces can be positioned individually, as part of a sequence or as part of a series of sequences. Accordingly, with little effort, a user can position the user support surfaces of the wheelchair to a predefined position.

Food preparation apparatus and associated methods. In one method, dough is proofed in an oven compartment and then baked in the same oven compartment. Temperature and/or humidity can be controlled during proofing and/or baking cycles. A blower may be used, for example, to exhaust gas to ambient to reduce heat and/or moisture in the compartment. For example, the blower may be used between proofing and baking cycles to prepare an environment in the oven compartment for the baking cycle.

A patient's vital sign measurements are displayed in a fishbone diagram defined by a horizontal line with a vertical line crossing it to form four compartments. The patient's respiratory rate and heart rate are displayed in assigned compartments above the horizontal line separated by the vertical line and the patient's oxygen saturation (SpO2) and temperature are displayed in assigned compartments below the horizontal line separated by vertical lines. Two diverging horizontal lines form a sideways V are connected with the right hand side of the horizontal line to define a fifth compartment in which the patient's blood pressure is displayed.
