Abstract: A controller for a barrier operator is provided. The controller includes an energy source and a sensor configured to determine whether a predetermined event is satisfied and generate a modulation signal based on the predetermined event. The controller further includes a dimming device communicatively coupled to the sensor and the energy source, wherein the dimming device generates a modified current or a modified voltage in response to the modulation signal. A light source, most preferably an LED, is then electrically coupled to the dimming device and to illuminate in response to the modified current.

Abstract: An access control system controls synchronous or coordinated motion of two or more gates using a controller that calculates travel time for each gate and that adjusts the speed of the motors driving the gates to so allow the gates to reach the open and/or closed position at the same time, regardless of the length of the individual travel paths of the gate.

Abstract: A controller for a barrier operator is provided. The controller includes a control board communicatively coupled to a device and a display communicatively coupled to the control board. The controller further includes one or more data processors configured to receive device data of the device, generate natural-language content and encoded content in response to the device data, and display the natural-language content and the encoded content on the display. A system including the controller and a handheld device is also provided. The handheld device includes a camera and a handheld display. The handheld device further includes one or more data processors configured to receive the encoded content utilizing the camera, retrieve remote informational content from a remote database based on the encoded content, and display the remote informational content on the handheld display.
