| 20080229666 | Gate opening and closing apparatus - A gate opener has a slide gate panel that slides between an open position and a closed position in order to control passage through the gate. A support plate has a lower spindle support and an upper spindle support and is secured to the ground in appropriate fashion. A motor assembly is rotatably disposed between the lower spindle support and the upper spindle support and has a sprocket operationally attached thereto. When the bidirectional motor within the motor assembly is operational, the sprocket, which directly gearably meshes with a drive rack gear on the gate, rotates causing the gate to slide back or forth. A magnetic reed switch on the sprocket, support plate or control box, senses the presence of a magnet located on either end of the gate deactivates the motor reverse its direction for the next cycle. | 09-25-2008 |

| 20110113692 | CHICKEN COOP DOOR MODULE - A chicken coop door module having a frame, a door, and a motor drive unit. The motor drive unit is configured to move the door toward the open position in response to receiving an opening signal so that the frame opening is unobstructed, move the door toward the closed position in response to receiving a closing signal so that the frame opening is obstructed, and prevent the door from moving when no signal is received. The door module receives an opening signal in the morning to let the chickens out of the chicken coop, and a closing signal in the evening to close the door to secure the chickens in the coop. When no signal is received, the door is prevented from moving by the motor drive unit so that when open, the chickens may freely enter and exit the coop; and when closed, predators cannot open the door and attack the chickens. The chicken coop door module may include a controller to provide the opening signal and the closing signal base on a signal from a timer or light detector. | 05-19-2011 |
