| 20080297370 | ROLLING CODE SECURITY SYSTEM - A rolling coda transmitter is useful in a security system for providing secure encrypted RF transmission comprising an interleaved trinary bit fixed code and rolling cede. A receiver demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and roiling codes with stored codes and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor to open or close a movable barrier. | 12-04-2008 |

| 20090140836 | MOVEABLE BARRIER OPERATOR TRANSLATION SYSTEM AND METHOD - A system includes a translator device that is configured to receive, using a pre-programmed native mode of operation, a first barrier actuation code transmitted by a transmitter according to a first code format. The translator device then analyzes the first barrier actuation code and verifies that it is a valid code. When a valid code, the translator device saves the information contained in the code, and creates a second barrier actuation code at least in part from information contained in the first actuation code and transmits the second barrier actuation code according to the second code format, which is different from the first code format. A barrier operator is coupled to the translator device and a barrier. The barrier operator has a receiver apparatus and the receiver apparatus receives the second barrier actuation code. The barrier operator determines whether the second barrier actuation code is valid, and when the barrier actuation code is determined to be valid, actuates the barrier. | 06-04-2009 |
| 20090146777 | Moveable Barrier Operator Feature Adjustment System and Method - At a moveable barrier operator, parameters are adjusted. At a first time, the moveable barrier operator is configured with at least one parameter and adjustment of the at least one parameter is disabled until a predetermined identification signal is received. At a second time, the predetermined identification signal is received and the at least one parameter is responsively adjusted. | 06-11-2009 |
| 20090175025 | PERMANENTLY INSTALLED LIGHT EMITTING ELEMENTS FOR A BARRIER OPERATOR - A barrier movement operator controls movement of a movable barrier. The barrier movement operator includes a head unit, including a chassis, for commanding the movable barrier to perform movable barrier functions. A plurality of closely mounted light emitting elements are fixedly mounted onto the head unit. A heat sink is in thermal communication with the set of light emitting elements and with the chassis of the barrier movement operator to dissipate thermal energy from the set of light emitting elements. A controller is utilized for controlling the head unit to provide power to the set of light emitting elements. | 07-09-2009 |

| 20100060413 | Garage Door Operator Having Thumbprint Identification System - A movable barrier operator having thumbprint identification in either a remote radio frequency transmitter, or a receiver/barrier operator system or both is provided. A control circuit with a non-volatile memory receives thumbprint information from a fingerprint detector device and stores the information, identifying an authorized user. On subsequent operation of the fingerprint detector, a fingerprint data set is received in the control circuit and an attempt is made to match the incoming data with previously stored data thus establishing the identify of the user according to highly reliable biometric principles. As an option, a variety of different actions can be taken based upon the perceived identity of a particular individual, as well as the type of device communicating with the receiver/barrier operator. | 03-11-2010 |
| 20100238117 | Movable Barrier Operator System Display Method and Apparatus - A movable barrier operator system operational component includes an integral display comprising at least one of a numeric display, an alphanumeric display, and a graphics display. The display can comprise an active display or an active interactive display and can further operate in conjunction with adjacent user-input interface opportunities. So configured, numerous user interface events can be highly leveraged to contribute to ease of installation and ease and reliability of use. | 09-23-2010 |
| 20100257784 | Movable Barrier Operator with Energy Management Control and Corresponding Method - A movable barrier operator system wherein one or more of the various components of the system is configured to operate selectively in at least either of two operational modes. Each operating mode is characterized by a corresponding energy usage profile. The operational status of the system is monitored and operating modes are selected that serve both to substantially ensure proper operation given current likely operational expectations and an overall desire to reduce energy consumption. | 10-14-2010 |
| 20100308960 | Method and Apparatus for a Rolling Code Learning Transmitter - A barrier movement operator system having a receiver for receiving, learning and responding to transmitted rolling code type access codes; at least one trained transmitter for operating the system by transmitting a rolling code type access code to the receiver; at least one learning transmitter for learning the rolling code type access code from said trained transmitter in order to operate the system; a controller for evaluating the relationship between the learning transmitter rolling type access code and the trained transmitter rolling type access code; and a device for providing a barrier movement in response to access codes received by the receiver. The barrier movement operator provides a method of learning valid security codes by a security code receiver comprising the steps of receiving a first security code, then within a predetermined period of time receiving a second security code, having a predetermined relationship to the first security code; and storing a representation of the second security code as a valid security code. | 12-09-2010 |
