Abstract: An ophthalmic device includes an optic including an optic axis and a closed-loop haptic structure coupled to the optic via a frame surrounding the optic, the closed-loop haptic structure including a closed loop extending from first and second attachment points to the frame. The closed loop includes a first hinge and a second hinge. The first hinge has a first section having a first component extending in a first angular direction, a second section having a second component extending in a second angular direction opposite to the first angular direction, and a first connecting section between the first section and the second section. The second hinge has a third section having a third component extending in the second angular direction, a fourth section having a fourth component extending in the first angular direction, the fourth section being connected to the second section to form the closed loop.

Abstract: A moveable barrier proximate to an entry point to the secured area may obstruct entry to the secured area or permit access thereto. The barrier may be used in conjunction with one or more sensors that are each capable of detecting metallic objects. In response to determining that a metallic object does not satisfy one or more access parameters, the barrier may be caused to block access to the secured area. The one or more sensors may be in communication with a logic controller that permits a user at a human-machine interface to reset or reconfigure each of the one or more sensors.

Abstract: Methods, systems, and apparatuses for controlling access to a secured area are disclosed. A moveable barrier at an entry point to the secured area may include one or more light arrays affixed to a front surface of the barrier to provide information to persons proximate to the bather using one or more illumination patterns. A programmable logic controller in communication with the one or more light arrays may select a pattern of illumination for the one or more light arrays. A rear light array affixed to a rear surface of the barrier may be configured by the programmable logic controller to duplicate illumination patterns selected for the one or more light arrays affixed to the front surface of the barrier.

In response to determining that a metallic object does not satisfy one or more access parameters, the barrier may be caused to block access to the secured area.

Abstract: Systems and methods for monitoring and controlling access to a secured area are disclosed. A moveable barrier may be used in conjunction with one or more types of sensors and a logic unit to monitor and control access to the secured area. The barrier may permit access to the secured area when a set of access parameters are satisfied. A user at a human-machine interface may remotely communicate with persons detected at the secured area.
