Patent ID: 8070128

Claim:
A dual function flush device comprising: a housing comprising a front portion and a rear portion, the rear portion tiltable in relation to the front portion; the rear portion of the housing having a motor unit with a rotating shaft, the rotating shaft further having a drive cam at a front end proximate the front portion of the housing; the front portion of the housing including a plunger having a first end and a second end with a face plate therebetween, the front portion of the housing further including a plunger bushing with the plunger slidably disposed therein, the plunger bushing engagable with a plunger chamber housing to form a plunger face plate chamber with the faceplate of the plunger disposed therein, the plunger extending through the plunger bushing such that the first end is adjacent the plunger bushing and the plunger further extending slidably through the plunger chamber housing such that the second is adjacent thereto; a plunger cam positioned at the second end of the plunger; the drive cam in operative communication with the shaft of the motor and engagable with the plunger cam such that rotation of the shaft rotates the drive cam which interacts with the plunger cam, moving the plunger along its longitudinal axis; and a non-contact sensor unit, in operative communication with the motor unit, at least partially disposed within the housing, the non-contact sensor positioned to detect user status; wherein actuation of the motor by the non-contact sensor or relative tilting of the rear portion of the housing in relation to the front portion of the housing engages the drive cam against the plunger cam, driving the plunger along its longitudinal axis.
