Abstract
A rotary pushbutton and touchpad device, a system and a method detect rotary movement, axial displacement and touchpad gestures. The device has a knob which may rotate about an axis of rotation, may move upward and downward on the axis of rotation, and may have a touchpad. The touchpad may be fixedly connected to a rotary girder and/or a shaft clip within the knob which may prevent the touchpad from rotating when the knob is rotated. A substantially hollow and cylindrical outer shaft may be fixedly connected to the knob so that rotation of the knob rotates the outer shaft. The shaft clip may be fixedly connected to an actuator shaft which extends through the interior of the outer shaft and conveys axial displacement of the knob. Shutters extending from the outer shaft may rotate into or away from a position between a light emitter and a light pipe.

8. A system for detecting rotary movement, axial displacement and touchpad gestures, the system comprising:
-
a knob having a knob top and a knob bottom wherein the knob top has an opening and further wherein the knob bottom is fixedly connected to the knob top; a touchpad located within the opening wherein a user manipulates the touchpad to perform the touchpad gestures; a touchpad PC board located within the knob wherein the touchpad PC board generates a signal indicative of the touchpad gestures applied to the touchpad; an encoder housing from which an outer shaft extends wherein the outer shaft has a top end, a bottom end, an interior and an exterior and further wherein the top end of the outer shaft is fixedly connected to the knob bottom; shutters located within the encoder housing wherein the shutters extend outward from the outer shaft into the exterior of the outer shaft at the bottom end of the outer shaft; an encoder PC board located within the encoder housing on one side of the shutters wherein the encoder PC board detects an intensity of light; a housing base from which a base shaft extends wherein the base shaft extends through the interior of the outer shaft to a position between the knob bottom and the knob top wherein the knob bottom slides on the base shaft in a direction toward the housing base in response to an applied downward force on the knob top and slides on the base shaft in a direction away from the housing base in response to a release of the applied downward force on the knob top; an actuator shaft which slides in the base shaft in a first direction toward the housing base and perpendicular to the housing base in response to an applied downward force on the knob top and slides in a second direction away from the housing base and perpendicular to the housing base in response to a release of the applied downward force on the knob top; and a base PC board located within the housing base wherein an elastically deformable dome is located on the base PC board and between the actuator shaft and the base PC board and further wherein the elastically deformable dome has a base and a center wherein the base of the elastically deformable dome is fixedly connected to the base PC board and further wherein the base PC board generates a signal indicative of the axial displacement of the knob in response to depression of the knob pushing the actuator shaft downward into the elastically deformable dome so that the center of the elastically deformable dome contacts the base PC board. - View Dependent Claims (9, 10, 11)
