Abstract
An improved pressure-actuated control bar is disclosed which may be located on a door to control access or egress through the door, whereby the control bar is used to trigger unlocking or opening, or both unlocking and opening, of the door following pressure being exerted on the control bar by an individual desiring access or egress through the door. A comparator is used to determine whether pressure exerted on the control bar and sensed by a pressure-sensitive component with no moving parts is sufficient to trigger unlocking or opening, or both unlocking and opening, of the door. A second embodiment describes a push/pull door access handle which may be used on a handicapped-accessible door to initiate powered opening of the door when the handle is pulled, and to cause immediate cessation of the opening of the door when the handle is pushed.
