Claim 0:
1. A control knob for controlling operation of a machine, the control knob including:
an attachment surface configured for attaching the control knob to a surface of the machine;
a display platform formed with a recessed section and shaped and dimensioned to allow seating of an electronic display module in the recessed section so that it remains in a fixed position on the display platform;
a display member comprising the electronic display module disposed thereon;
an operational mode display controller for controlling display of operational modes of the machine upon the electronic display module, said operational mode display controller being configured for rotational movement around the electronic display module amongst a plurality of rotational positions, said operational mode display controller being operably connected with the electronic display module such that, responsive to the rotational movement of the operational mode display controller amongst the plurality of rotational positions, the electronic display module is configured to display a plurality of operational modes of the machine corresponding to the plurality of rotational positions;
an operational mode selector for controlling selection of one of the plurality of operational modes of the machine when said one of the plurality of operational modes is displayed on the electronic display module, the operational mode selector being configured for depressible movement to actuate selection of the operational mode displayed on the electronic display module;
a contactless motion sensor for sensing motion of the user's hand, and being operably-connected to the display member to provide for sensing motion of the user's hand, with the display member being configured to switch operation of the machine from a sleep mode to an active mode when the contactless motion sensor senses motion of the user's hand;
a sensor guide configured for controlling a field of motion within which motion of the user's hand is sensed by the contactless motion sensor to allow for switching operation of the machine from the sleep mode into the active mode;
the contactless motion sensor is configured for engagement within the sensor guide which protects and controls the field of motion that is sensed by the contactless motion sensor in use; and
a printed circuit board having an electrical connector configured for interconnection with machine systems via wiring to effect power and/or data/signal communication therebetween, and wherein securement tabs extend from the display platform downwardly through slots disposed in the printed circuit board and extend through a central passage of the operational mode display controller so as to engage with corresponding securement tabs extending upwardly through the central passage of the operational mode display controller from the attachment surface.
