Patent number: 6417780Abstract: A radio control device is provided that has the D/R function wherein the rate can be switched by a simple operation without impairing the operability of a stick. The adjustment value (rate) determining a relationship between stick operation amount and servo motor operation amount is switched at the changeover point arbitrarily set within a range of stick operation amounts. The rate 1 is 100% while the rate 2 is 60%. The point 1 is set to the position corresponding to about 65% of the maximum value of the stick operation amount in the right direction (or down direction). The point 2 is set to the position corresponding to about 85% of the maximum value of the stick operation amount in the left direction (or up direction). In the rate 2, the rudder does not effectively work over the range where the operation amount of the stick is relatively small. When the adjustment value exceeds the point, the mode enters the rate 1, so that the rudder works effectively.Type: GrantFiled: July 12, 1999Date of Patent: July 9, 2002Assignee: Futaba CorporationInventors: Giichi Naruke, Youichi Konno, Masahiro Tanaka

Patent number: RE37784Abstract: A movable barrier or garage door operator has a barrier drive for moving the movable barrier or garage door between open and closed positions. Motion of the barrier is detected by a tachometer connected to the barrier drive or by upper and lower barrier travel limit switches. A test is made to determine if the barrier has been commanded to be in a closed state and to determine if a preselected time interval has elapsed following closure of the barrier. When both of those conditions are present and the door is moved upward without authorization an alarm signal is generated and can signal the barrier drive to apply a closing force. The timer prevents the barrier from being closed on a person or obstacle during normal operation and prevents injury. An obstacle detector also prevents unwanted closure on an obstacle.Type: GrantFiled: July 11, 2000Date of Patent: July 9, 2002Assignee: The Chamberlain Group, Inc.Inventors: James J.
